3 Polyamide (PA)

PLASTIC

3.1 Chemical properties

3.2 Parts made of polyamide

3.3 Special characteristics of polyamide

PA is characterized by a good resistance to oils, fats, and lubricants as well as to weak bases. Polyamide, however, is degraded by mineral acids, strong organic acids, oxidants and phenols.

Please do not use cleaners containing inorganic solvents on plastic parts.

This material is resistant to all commercially available cleaners, and to detergents, alcohol and soap solutions in particular. Polyamide is less resistant to acids.

From experience, cleaners based on soap solutions are the best choice to clean polyamide.

Abrasive cleaners will damage the surface texture, leaving matt, dull blemishes. Do not use such cleaners on plastic.

• Base of series 9200 Papilio

• Seat shell of series 2000_2080 uni_verso

In general

Excellent toughness combined with a good hardness.

Excellent abrasion resistance and great dimensional stability at high temperatures. Mechanical properties largely depend on the moisture content of the formed parts. Milky, opaque finish. Resistant to benzine, benzene, and many other solvents. Physiologically safe. Good level of sound absorption. Good friction behaviour. Processed in accordance with the standard thermoplastic processes. Polyamide meets the fire prevention requirements of DIN EN 1021 part 1+2.

Polyamide 6

Excellent toughness, even at cold temperatures. Hard. Some types of this group are suited for the production of plastic foils.

Polyamide 6.6

This polyamide boasts the best hardness, stiffness, abrasion resistance, and dimensional stability at high temperatures.

Polyamide 6.10

Low level of water absorption, therefore well-suited for parts requiring an increased dimensional stability

Polyamide 11

Very low level of water absorption, therefore excellent dimensional stability compared to other polyamides (with the exception of polyamide 12). Lower hardness and stiffness compared to polyamide 6. Polyamide 11 has the best shock resistance by far of all polyamides.

Polyamide 12

Even less water absorption than PA 11. Better shock resistance than polyamide 6, but not as good as PA 11. Increased resistance to stress degradation in comparison with other polyamides.

4 Integral foam (polyurethane)

This type of foam offers the advantage of having a closed-pored surface akin to a skin which is approximately 1 – 2 mm thick. The material is impervious to liquids, dirt and germs and therefore easy to clean and to disinfect. Nowadays integral foam parts are very often used for medical and cosmetic products. Shower seats in hospitals, arm pads on wheel-chairs, add-on parts for dialysis beds, just to name a few, are made of this material and have been found to be physiologically harmless. These foams have been approved according to DIN EN 30993. The production processes of integral foam are very similar to those of other PU foam parts, without CFC, azo dyes or PCB, containing no heavy metals.

PP is characterized by an excellent resistance to chemicals and a limited resistance to acids and bases.

The foam parts conform with the standard DIN 75200 and with the American Standard for Automobile Interior Equipment and also meet all the requirements of DIN EN 1021 Part 1 and 2, low specific weight (density). However, hard and sharp objects may damage the surface structure when used improperly.

From experience, we advise using a cleaner that is composed of soap-suds. Integral foam is characterized by a good resistance to oils, fats, lubricants, as well as to weak bases. In contrast, it is badly deteriorated by aggressive acids and bases.

Never use a cleaner containing inorganic solvents to clean plastic parts.

This material is resistant to most household used cleaners, especially detergents, alcohol and bases. Integral, however, is not resistant to acids. We have learned from practical experience that all cleaners composed of soapsuds are ideally suited to clean integral foam.

Abrasive cleaners destroy the surface structure and may leave matt blemishes. We therefore strongly advise against abrasive cleaners.

PLASTIC

All commercially available cleaners, such Pril, soapsuds, Rei, Dor, etc. can be used to clean HPL and MFC tops. In case of stubborn stains, cleaning solvent, turpentine or spirits can be used (however no scouring agents).

Even high-quality plastics can get damaged! Therefore never use any grinding or scouring cleaners! Do not put any hot pans or irons on plastic-coated surfaces! HPL table tops are resistant to boiling water.

In case aggressive cleaners or mixtures are used in hospitals, we recommend prior testing on material samples by way of precaution. When cleaning the lipping, please make sure that not too much cleaning liquid comes in contact with the lipping joint or with the wooden lipping. The surfaces should be cleaned with a soft, clean, non-fluffy cloth. In order to remove sticking dust or light soiling, you can use normal cloths, moisten them with water and add a small quantity of commer-cially available cleaners and wipe the surface clean without applying too much pressure (no scouring!). Subsequently, wipe the surface dry with a clean cloth. Commercially available all-purpose cleaning products, such as Mr. Clean, Ajax, Sidolin, or water-soluble washing powders, are suitable. Please use these cleaning products according to the manufacturer’s instructions as indicated on the packaging!

In case of stubborn stains, the above-mentioned cleaning products can be used in higher concentrations with longer application times (f.i. Bref Power or similar fat solvents), however never use them undiluted!

Always rinse the surface generously with clear water or glass cleaner using clean cloths and subsequently wipe the surface dry.

Neveruse scouring milk, such as ATA, Viss, or similar cleaners containing scouring agents, as these products might damage the surface and leave unsightly scratches or scouring marks. We strongly advise against the use of aggressive bathroom or toilet cleaners.

In case of stubborn stains, such as coffee or red wine, we recommend frequent cleaning cycles. Cleaning dilutions or cleaning solvents can be used to keep the surfaces clean (Attention: inflammable!). The surfaces must be rinsed with clear water every time without fail. Especially EM surfaces need regular cleaning cycles. Liquids, such as coffee, milk, should be wiped off as soon as possible and not be left to dry.

5 Cleaning and care instructions for HPL and MFC tops,

lipping and laminated seat shells

(22)

PLASTIC

The international committee of manufacturers of decorative synthetic surfaces has issued the following recommendations regarding the cleaning and care of HPL and MFC tops:

• Lightly soiled table tops can be cleaned with a soft, moistened cloth • More persistent stains can be treated with some hot soapy water or with a commercially available cleaner which does not contain any scouring agents in order to avoid scratches on the surface

• Stubborn stains, such as varnishes, lacquers, adhesives, ink, lipsticks, can be removed with organic solvents, f.i. acetone, trichloroethylene, cleaning alcohol, etc.

The surface of HPL and MFC table tops is resistant to the following substances:

Acetone, alcohol, red and white wines, spirits, beer, benzine, benzol, blueberries, cola drinks, vinegar, meat and sausages, lemonades, coffee, tea, cocoa, potassium permanganate, carbolic acid 5 %, lipstick, milk and dairy products, nail polish and nail polish remover, fruit and vegetable juices, petroleum, ammonium hydroxide, salt solutions, shoe polish, soap and detergents, mustard, soda 2 %, turpentine, carbon tetrachloride, animal and vegetable fats and oils, ink and recording ink, hot water, citric acid, onions.

lipping and laminated seat shells

PLASTIC

On the following page, you find the cleaning recommendations with regard to HPL table tops issued by the Technical Group Decorative Laminated Table Tops within the department Semi-Finished Products at the Frankfurt-based GKV (German Association of the Plastics-Processing Industry) (last update: April 2000)

These cleaning instructions have been worked out by the International Committee of the Decorative Laminates Industry (ICDLI) according to the latest developments in processing technology in Europe.

Laminated seat shells

The laminated seat shells of series 2100_2180 uni_verso can be cleaned with some hot soapy water or with a commercially available cleaner. Please take heed that the cleaner doesn’t contain any scouring agents at the risk of damaging the surface. Heavy soiling can be treated with acetone.

1. Application area

The information supplied in the table on the following page applies to surfaces of decorative high-pressure laminated (HPL) and MFC table tops according to EN 438, part 1, and to the parts produced with these materials. These cleaning instructions apply to all types of soiling, either due to normal usage or caused during the processing and assembly of HPL parts.

2. General remarks

HPL table tops do not require any particular care because of their hard-wearing and hygienically impervious surface. In general, HPL surfaces are easy to clean; this rule also applies to textured HPL surfaces. No care products are necessary! Furniture polish as well as all cleaners containing wax tend to fill up the surface texturing, building a sticky, unsightly, dirt-binding film; we strongly recommend against using this type of cleaners! While in use, the decorative laminates should be cleaned regularly. Please use mild cleaners that do not contain any scouring agents, as these can scratch the surface or reduce the surface’s gloss level. In case of heavy soiling, special cleaners may be necessary. In such cases, please observe the manufacturer’s instructions (f.i. adequate ventilation, etc.)

3. Special recommendations for high-gloss surfaces

Special attention should be given when cleaning high-gloss HPL surfaces. We strongly recommend against the use of cleaners containing scouring or grinding agents or Vienna chalk, as these products can lead to an irre-versible change in the gloss level. It is absolutely imperative to remove grains of dust or any other impurities from the surface before the actual cleaning process in order to avoid scratches. Please only use residue-free drying cleaners or cleaning solutions and subsequently wipe the HPL surface dry with a soft, clean, absorbent and dry paper cloth (paper towel) without leaving streaks.

4. Cleaning instructions

The cleaning instructions as well as all elaborations on possible difficulties in this table are arranged according to the soiling degree. We would like to stress the fact that the mildest cleaning method must be applied first before trying a more aggressive method.

PLASTIC

Owing to the fact that the fibres are non-absorbent, stains can be removed with a vacuum-cleaner; stubborn stains must be treated with a spray extraction cleaner. Dab spilled liquids away with an absorbent cloth. Dried-in stains can be removed using a mild cleaning agent and a soft brush, subsequently vacuum-clean.

In the long term, signs of usage are inevitable given the soft surface texture. We therefore recommend regular cleaning and brushing cycles. It is to be expected that the surface texture is roughened or smoothed through permanent use. This material is not resistant to strong mechani-cal impacts concentrated on one spot. Disinfectants can theoretimechani-cally be applied to the seat shell. However, due to the rough surface, any disinfec-tant would loose some of its efficiency. We therefore advise against the use of disinfectants.
