Flat Gasket made of HDPE
Product specification
Flat seals made of Polyethylene, transparent fitting outer or inner thread.
General Information
Excellent impact resistance, even at low temperatures
Good resistance to weather and aging
Antiadhesive, waxy and soft surface
High tearing strength
Physiologically safe
Good dielectrical properties
Chemical features:
Good resistance to weak and strong alkalis and acids, except oxidizing acids, and only relatively suitable for hydrofluoric acid; resistant to organic acids, aliphatic hydrocarbons, greases and mineral oils, alkohols, ketones, esters and amines.
Material specification:
Very low tendency to swell when in contact with polar fluids (e.g. alkohols, organic acids, esters, ketones etc.) as well as greases, oils and waxes.
Resistance to weather: the material degrades when exposed to direct sunlight
