Steam Resistance Fluoroelastomer Custom Rubber Molding AFLAS FEPM Rubber O Ring
Description:
Aflas is a peroxy vulcanized fluoroelastomer FEPM made by
alternating copolymerization of tetrafluoroethylene and propylene.
The long-term use temperature reaches 230 degrees Celsius.
It also has excellent oil resistance, acid resistance, high temperature steam resistance,
and acid gas resistance. It is mostly used for durable sealing materials, gaskets and O-rings.
Especially the alkali resistance and amine resistance are outstanding,
and it has the best insulation performance in fluoro rubber.
Usage:
Aflas are widely used in food processing, nuclear power, electricity, oil extraction, chemical plant,
automobile, machinery and many other industries.
Application:
1. Tetrapropylene fluorine rubber has excellent heat resistance and chemical resistance,
and is used in equipment seals such as O-rings in chemical plants, petroleum extraction, food processing and other industries.
2. Not only for engine oil, but also for cooling water with excellent durability.
3. Aflas' copolymer has excellent electrical insulation and is suitable for wire sheathing.
4. Aflas has excellent durability to additives such as dispersant and antioxidant added in engine oil.
5. Aflas has various grades with excellent extrusion processability and can be used for film processing.
It is used in products such as large area film and cutting processing.
6. Aflas can be processed into sponge products. AFLAS,
which takes into account durability and flexibility, makes fluoroelastomers more versatile.
