Frivanit material is used to make parts for completing vehicles and operating in temperate and tropical climates at ambient temperatures from -40°С to +45°С and humidity up to 95%.
There are three grades of Frevanit:
- material 221-111-70- (has the properties of damping torsional vibrations in the vehicle transmission); Available thickness 1.0 mm
- material 42-321-67- (serves to hold the heater control levers in a given position); The produced thickness is 1.5-2.0 mm
- material 42-334-67- (serves to perceive the axial load at the moment of engaging and disengaging the clutch). Available thickness - 1.5-2.0 mm
The composition of the material includes the following ingredients:
Rubber; asbestos; sulfur; 2.2 mercapto-benzothiazole; fillers to ensure that the required characteristics are obtained.
