Processing suggestions

It is recommended to use 0.6%-1% of bis (2,5-dimethyl-2,5-bis (tert butylperoxy) hexane as a curing agent. Customers should determine the most suitable vulcanization temperature and time based on product size and vulcanization method.


Advantage

1. Wide temperature range for use (-60 ℃~200 ℃);

2. Excellent oil resistance, solvent resistance, and chemical medium resistance;

3. Good strength and resilience;

4. Good insulation;

5. Good breathability.


Application

1.Aviation industry: as fuel oil and lubricating oil resistant seals/contacts on aircraft.

2.Automotive industry: various types of vehicle sealing rings, oil seals, diaphragms, conduits, valve linings, etc.

3.Petrochemistry industry: sealing components for equipment such as pumps, valves, and oil tanks that are resistant to high temperature, low temperature, and chemical attack.

4.Medical and health department: medical devices and artificial organs

5.Military industry: harsh applications that require low temperature/oil/acid resistance in the environment.
