Acetal absorbs very little water and remains hard at temperatures down to -40°C. It is also highly heat resistant, melting at 180°C. Acetal may be approved for contact with foodstuffs. Disposal: pure acetal is classified as recycling code 07 (other plastics) and can be melted down if cleanly separated from other waste.
Composites of this material are classified as follows:
- plastic/aluminium – recycling code 90
- plastic/tinplate – recycling code 91
- plastic/miscellaneous metals – recycling code 92
Acrylonitrile butadiene styrene – ABS
Acrylonitrile butadiene styrene is resistant to oil and can withstand high temperatures, permitting continuous use between 85°C and 100°C. Disposal: ABS is classified as recycling code 07 (other plastics) and can be melted down if cleanly separated from other waste.

Polyamide 6 – Nylon 6 – PA
Polyamide 6, commonly known as Nylon 6, is used as a base material for various plastic seals. This thermoplastic is very strong, rigid and tough. It is highly resistant to wear, friction and abrasion.

Polyamide 6 is also highly resistant to heat, chemicals, lubricants and motor fuels. However, polyamides can absorb water, which make them susceptible to frost damage.
Disposal: PA is classified as recycling code 07 (other plastics) and can be melted down if cleanly separated from other waste.

Polystyrene – PS
Polystyrene is used as a base material for various plastic seals. This thermoplastic is resistant to all alkalis and mineral acids, but not to non-polar solvents such as petrol, ketones (eg. acetone) and aldehydes.

Polystyrene absorbs little to no water, so it is not susceptible to frost damage. However, it does not have long-term resistance toUV light and to heat; prolonged exposure to temperatures of 55°C and above will speed up the aging process. Polystyrene is classed as physiologically inert, making it safe for contact with foodstuffs; it is the only plastic that is approved for use in storing raw meat and fish.
Disposal: polystyrene is classified as recycling code 06 and can be melted down if cleanly separated from other waste.

Seals made from PS: Polywedge.
Polycarbonate – PC
Polycarbonate is used as a base material for various plastic seals. It is stiff, strong, tough and hard. Polycarbonates are resistant to water, as well as many mineral acids, oils and fats.

Polyethylene – PE
Polyethylene hardly absorbs any water, so it is not susceptible to frost damage. It is heat resistant up to 90°C, but prolonged exposure to temperatures above 80°C will lead to the material becoming softer. HDPE does not have long-term resistance to UV light; prolonged exposure to direct sunlight will slowly make it brittle.

Polypropylene – PP
Polypropylene is used as a base material for various plastic seals. The rigidity, hardness and strength levels of this thermoplastic are higher than those of Polyethylene, but lower than those of Polyamide.

Polypropylene is resistant to most organic solvents and fats, and to dilute acids and alkalis. It is heat resistant up to 105°C, but becomes brittle under cold conditions. Polypropylene is classed as physiologically inert, making it safe for contact with foodstuffs and for pharmaceutical applications.
