SBS is the largest yield of SBCs (accounting for more than 70%), the lowest cost, a wide range of applications, based on styrene, butadiene as a monomer triblock copolymer, both plastic and rubber characteristics, known as the "third generation of synthetic rubber." Similar to styrene butadiene rubber, SBS can be in contact with water, weak acid, alkali, etc., with excellent tensile strength, large surface friction coefficient, good low temperature performance, excellent electrical properties, good processing properties and other characteristics, becoming the largest consumption of thermoplastic elastomer.

B. High viscosity: the same amount of oil absorption also shows higher solution strength, which can effectively reduce the thermal shrinkage of products.
C. Fast forming speed: under the same cooling time, it can perform better forming effect and effectively improve processing efficiency.
D. Good optical properties: non-oil-filled sheet forming, fog degree up to 5.0%, transparency in the forefront level.
Low gel content: better coating effect and thinner coating thickness, effectively reducing adhesive production costs.
E. Low Gel Content: The raw materials used in the product meet the requirements of food grade, do not contain the restricted additives such as king phenol and phthalol, meet the testing requirements of ROSH and REACH, and have strong safety and reliability.
F. Environmentally Friendly.
