FKM Peroxide Curable Copolymer

FKM Peroxide Curable Copolymer also known as Peroxide Curable FKM Raw Polymer, refers to peroxide crosslinkable fluoroelastomer copolymers, a special type of FKM (fluoroelastomer). This FKM is vulcanized (crosslinked) with organic peroxides, which gives it different performance characteristics than traditional bisphenol-crosslinked FKM.

Applications of FKM Peroxide Curable Copolymer

1. Automotive Industry

• Engine seals, fuel system seals, O-rings, oil seals, gaskets

• Resistant to high temperatures, aviation gasoline, automotive fuels, and synthetic lubricating oils

• Suitable for long-term use in harsh environments requiring minimal compression set

2. Chemical Industry

• High-temperature, corrosion-resistant pipe linings, hoses, and pump seals

• Excellent resistance to acids, alkalis, strong oxidizers (e.g., oleum), and various non-polar solvents

• Ideal for applications exposed to extreme chemical conditions

3. Oil & Gas Industry

• Steam, acid, and alkali-resistant seals for demanding environments

• Suitable for extreme conditions involving high-temperature exposure, aggressive chemicals, and oil-based fluids

• Long-lasting performance in harsh outdoor and underground applications

4. Aerospace Industry

• High-temperature sealing materials for aircraft and space applications

• Exceptional resistance to radiation, ozone, and weathering

• Ensures durability in environments with fluctuating pressure and temperature

5. Electronics and Semiconductor Industry

• Used in coatings and components requiring high-temperature and chemical resistance

• Protects sensitive equipment from corrosive chemicals and thermal degradation

• Ideal for advanced industrial applications requiring long-term material stability

Widely used for manufacturing:

• Washers, gaskets, O-rings, V-rings, oil seals, diaphragms

• Rubber pipes, cable sheaths, heat insulation cloth

• Valve plates, expansion joints, rubber rolls, coatings

• Pasty room temperature vulcanization putties

Ideal for applications requiring resistance to:

• High temperatures

• Fuels (aviation gasoline, automotive fuel)

• Lubricating oils (synthetic oils)

• Fluids (various non-polar solvents)

• Corrosion (acid, alkali)

• Strong oxidizers (oleum)

• Ozone, radiation, and weathering

Features and Benefits

• Excellent heat resistance: better resistance to high temperature environments (typically up to 230-250°C) than bisphenol cross-linked FKM.

• Better chemical resistance: especially to strong bases, amine chemicals, vapors and organic acids than bisphenol cross-linked FKM.

• Better low-temperature flexibility: Compared to conventional bisphenol cross-linked FKM, it maintains a certain degree of elasticity at lower temperatures (e.g. -10°C to -20°C).

• Lower Compression Set: Suitable for seals that are subjected to prolonged pressure, such as O-rings and oil seals.

• No Hydrogen Fluoride (HF) by-products: FKM Peroxide Curable Copolymer avoids the problem that bisphenol cross-linked FKM can decompose at high temperatures to produce HF.

FKM Peroxide Curable Copolymer stands out for its superior heat resistance, chemical stability, and low compression set, making it the ideal choice for industries requiring durable and high-performance sealing solutions.

The watch band made of FKM Peroxide Curable Copolymer features a dense, high-quality texture that is soft, skin-friendly, hypoallergenic, stain-resistant, and exceptionally comfortable and durable to wear. Additionally, it can be produced in a variety of trendy colors. Beyond watch bands, this material is also suitable for manufacturing specialized clothing and other applications.
