Rubbers

BS is the abbreviation of styrene butadiene styrene three block thermoplastic elastomer. It is also known as thermoplastic styrene butadiene rubber, and is known as the third generation synthetic rubber. SBS has dual characteristics of both plastic and rubber, that is, it is plastic at high temperature and is elastic at room temperature. Do not need vulcanization, it has the properties of vulcanized rubber; it does not have to be made of plastic, but it has the properties of thermoplastic. SBS has good compatibility with many polymers, excellent solubility, melting at high temperature, low melting viscosity, easy to modify and so on. It has been widely used in architectural decoration, printing compound film, pressure sensitive adhesive, wood industry and bag shoe making industry.

• Synthetic Rubber includes SBR (Styrene Butadiene Rubber), BR (Butyl Rubber), PBR (Poly Butadiene Rubber), SIS Block Copolymer (Styrene - Isoprene - Styrene) , SBS Block Copolymer and SEBS.

At present, the main adhesives for decorative use are chloroprene rubber and SBS adhesives. SBS adhesive because of its structural characteristics, determines the chloroprene adhesive and compared with the initial adhesion and poor bonding strength is not big enough, especially for polar material adhesion is poor, maintain time is too short, not conducive to the construction operation, heat resistance, weather resistance and poor defects, application in the decoration industry has been extremely limited.

• PVCHEM emphasizes the importance of consistent quality and professional services as key factors for fostering long-term business relationships.
