Polyurethane Gaskets
Polyurethane is known for its excellent elasticity, tensile strength and wear resistance with good permeability. They have good oil, heat and abrasion resistance which makes them compatible for industrial usage.
Over a temperature range of -40°C to +82°C (-40°F to +180°F), resistance to petroleum based oils, hydrocarbon fuels, oxygen, ozone and weathering is good. However, polyurethanes quickly deteriorate when exposed to acids, ketones and chlorinated hydrocarbons.
Polyurethane elastomers are special rubbers whose performance and characteristics of processability have been designed to satisfy particular technical demands in the sector of the rubber. Their items are characterized
in fact from the follow ing peculiarities:
Over a temperature range of -40°C to +82°C (-40°F to +180°F), resistance to petroleum based oils, hydrocarbon fuels, oxygen, ozone and weathering is good. However, polyurethanes quickly deteriorate when exposed to acids, ketones and chlorinated hydrocarbons.
- Excellent mechanical properties (elevated elongation and tensile strength)
- Good elastic characteristics from -76 to 230ºF (-60 to +110ºC)
- Good abrasion resistance
- Good compression set from - 22 to +158ºF ( -30 to +70ºC)
- Excellent resistance to light, ozone, to the oxidation and the atmospheric agents
- Good/excellent chemical resistance (aliphatic aromatic solvents)low gas permeability
