High styrene rubber HS-60 with styrene 60-65%
Overview:
High styrene rubber is a special variety of styrene butadiene rubber, because of its high content of combined styrene so called high styrene rubber, also known as hard rubber, is a nonpolar polymer, prepared by styrene, butadiene copolymerization through the emulsion, its chemical structure formula: -(CH2-CH=CH-) m-(CHC6H5-CH2)n-(CHC6H5-CH2)n-(CHC6H5-CH2)n-(CHC6H5) CH2)m-(CHC6H5-CH2)n-
White flake particles, its heat distortion temperature of 70-90 ℃, white solid, using a unique emulsion polymerization technology, high content of styrene monomer and butadiene monomer copolymerization as a rubber filler and reinforcing agent, and natural rubber, butadiene rubber, styrene butadiene rubber and other dienophthalic rubber blending, rubber hardness can be improved, aging resistance, abrasion resistance, tearing strength, tensile strength, and has easy mixing Processing, easy coloring and good thermoplasticity, electric insulation.
Mainly used for:
1. Light-colored outer tires of high-grade bicycles
2. Electrical insulating materials
3. Various rubber rollers and rubber sheets
4. Sports goods
