Material Notes:
Polyethylene has a good chemical resistance against almost all acids and bases, detergents and hot water. PE has good insulation properties and is easy to weld. The operating temperature is from -50°C to 90°C.Properties:low densityhigh toughnesshigh elongationvery good electrical and dielectric propertiesvery low water absorptionlow steam permeabilityhigh chemical resistancegood protection against stress crackingfood safesoft surfaceHF welding not recommendednatural color is not weather resistanceApplicationsTransport containerspumps and valve partsparts used in tank constructioncomponents with medical applicationsgasketssliding profilescomponents for the food industry
