1. NBR (Nitrile Butadiene Rubber)
NBR is a synthetic elastomer produced by copolymerizing butadiene and acrylonitrile through emulsion polymerization. It offers excellent resistance to wear, heat, and aging, outperforming natural rubber in oil-related applications. It is widely used in products exposed to petroleum-based hydraulic oils, lubricants, fuels, and kerosene.
2. VMQ (Silicone Rubber)
Silicone rubber is built on a backbone of silicon–oxygen (–Si–O–Si–) bonds with organic side groups. It demonstrates outstanding thermal stability and long-term aging resistance. VMQ also provides good flame retardancy and strong resistance to oils and many chemical media, making it suitable for high-temperature and demanding environments.
3. FKM (Fluoroelastomer)
FKM is a high-performance elastomer containing fluorine atoms within its molecular structure. It is well known for its exceptional resistance to heat, ozone, hydraulic fluids, and aggressive chemicals, making it ideal for severe operating conditions.
4. EPDM (Ethylene Propylene Diene Monomer)
EPDM is a terpolymer of ethylene, propylene, and a small amount of diene. It features excellent resistance to ozone, weathering, and many corrosive substances, along with good elasticity. Its natural color is light beige, and it is commonly used in outdoor and chemical service applications.
5. PTFE (Polytetrafluoroethylene)
PTFE is a fluoropolymer made from tetrafluoroethylene. It is chemically inert and highly resistant to corrosion, offering outstanding sealing performance, low friction, non-stick properties, electrical insulation, superior aging resistance, and excellent performance across a wide temperature range.
