AI Technical Summary

Problems solved by technology

Although SEBS has excellent rubber elasticity, excellent weather resistance, low temperature resistance, environmental protection performance, etc., there are some problems in using SEBS alone as an elastomer material. For example, compared with traditional vulcanized rubber, SEBS has excessive rigidity and compression. Disadvantages such as large deformation and high density; its upper temperature limit, solvent resistance, oil resistance, etc. are usually inferior to traditional vulcanized rubber, etc.
