Styrene-butadiene thermoplastic elastomer SBS behaves as a white or yellow rod or sheet of porous particles. It combines the advantages of both rubber and plastic, with excellent low temperature resistance, breathability and resistance to wet sliding. It is characterised by easy moulding, colouring, simple processing, no carburisation and low energy consumption. The remaining fractions can be recycled.
Key Applications: Widely used in footwear, adhesives, waterproofing membranes, modification of polymers and road asphalt, cables, toys and so on.
Advantages: Good elasticity and abrasion resistance, excellent processing performance, aging resistance. SBS rubber waterproof coating can keep the surface smooth and intact for a long time. It meets environmental protection certification standards for green building materials.
