EPDM rubber sheet has high resistance to heat with a temperature range of -40℃ to +250℃. It also possesses a good flame resistance and is usually self extinguishing. FKM's have excellent resistance to oxygen, ozone and natural weathering and also have outstanding resistance to compression, especially at elevated temperatures. Its resistance to most solvents and chemicals give long service life as it has excellent resistance against hydrocarbons, aliphatics, aromatic and chlorinated chemicals and resistance to acids and alkalis including oxidants. However, they have poor performance against ethers, ketones and bases.
- Ultra-high molecular weight
- Broad molecular weight distribution capability
- High diene content
- High to low polymer Mooney viscosity
- Oil-extended grades
- Wide range of ethylene content, from amorphous to semi-crystalline
- Higher long chain branching capability
- Ultra-clean, low gel content
