Mingyi Silicone(Anhui) Co., Ltd.
Product introduction:
MY F3672 is a silicone fluorine silicone rubber compound, which is formed by hot vulcanization after adding a vulcanizing agent (the vulcanizing agent is selected according to the process requirements).
Product advantages：
l Easy to process
l Good mechanical properties, with high strength and resilience
l Excellent oil resistance, solvent resistance, high and low temperature resistance, and low transformer oil dielectric loss

Note: The data in the table are typical product performance and are not factory standards. Heat-resistant additives must be added to meet heat-resistant requirements.
Processing suggestions:
It is recommended to use 0.6-1.2 parts of dipentadienyl vulcanizer (2,5-dimethyl-2,5-bis (tert-butylperoxy)hexane).
The customer should determine the most suitable vulcanization temperature and time according to the product size and vulcanization method.
Application:
Can be used for compression molding products, injection molding products; has good mechanical properties
Storage and shelf life：
MY F3672 is stored in the original unopened packaging at below 40°C for 12 months from the date of production
