  SEBS is an aliphatic double bond saturated by hydrogenation in order to expand the range of applications. The saturated thermoplastic elastomer SEBS has a saturated alkene structure in the soft segment, which has better weathering and heat aging resistance than SBS, and is stronger than SBS, so it has a wider range of applications.

  SEBS thermoplastic elastomer is a new type of polymer material between rubber and resin, not only can replace part of the rubber, but also can make good modification of plastic. It has excellent compatibility with other plastic materials, and because SEBS can be adjusted by adding extension oil to adjust the softness and hardness of the material, it can be made into a wide range of hardness foam products, the hardness of the finished foam products can range from 5C-60C, and the specific gravity is very low, between 0.08-0.3. SEBS has the characteristics of heat plastic, so the molded products after foaming can also be re-shaped to make the shape The foamed products can be recycled.

  SEBS foams have the following main characteristics.

  Compression deformation, non-slip characteristics better than EVA foam board, its physical properties and the traditional CR, EPDM, SBR similar, with the advantages of simple process, no rubber odor, easy color mixing.

  Because the aliphatic double bond has been saturated, it has the advantages of weather resistance, UV, oxygen, ozone and heat.

  It can be used in various rubber/plastic blends or used in various thermoplastic rubber/plastics as impact resistant, non-slip, wear resistant, compression resistant, and cold resistant modification materials.

  It has a soft touch similar to CR, SBR or PU foam, but the process is easier and does not cause odor or frosting problems.

  Compared with other high foaming, low specific gravity soft foaming materials, it has better physical and dimensional stability.    Excellent tensile recovery and elongation.

  Other characteristics include: good plasticity; high strength; good touch; high compression resistance; high flexibility; good weather resistance; good matte surface; high slip resistance and low temperature resistance.
