Product Description

SBS YH-791H is a thermoplastic styrene butadiene rubber.
Good tensile properties: high tensile strength, generally ≥18.0MPa, which makes it not easy to break under stress, and can maintain good integrity and stability.
High elongation at break: elongation at break ≥700%, which means that the material has good flexibility and elasticity, and can be restored to the original state within a large deformation range.
Suitable hardness: Shore A hardness ≥68, with a certain rigidity, can provide better support and wear resistance for products.
Low volatile content and ash: volatile content ≤1%, ash ≤0.20%, indicating that the purity of the material is higher, less impurity content, which helps to improve the quality and performance stability of the product.

Application field:
Asphalt modification: This is one of its main application directions. The addition of SBS YH-791H to asphalt for modification can significantly improve the weatherability and load resistance of asphalt, so that asphalt can maintain good performance under different environmental conditions, and is widely used in road construction, waterproof coils, etc.
Footwear industry: can be used to make soles, with good elasticity, comfortable wearing, good wet slip resistance, good air permeability, wear resistance and other advantages, and the weight of the sole is relatively light, can reduce the overall weight of the shoe.
Adhesive field: As an adhesive with high solid substance content, fast drying, low temperature resistance, and has a good solubility in hydrocarbon solvents, fast dissolution, good stability, strong cohesion, can be used in the production of shoe adhesives, wood fast drying adhesive, label tape adhesive and so on.
Plastic modification: It can be blended with polypropylene (PP), polyethylene (PE), polystyrene (PS) and other plastics to improve the impact resistance and flexure performance of products, and is used in the production of automotive steering wheels, bumpers, seals and other parts.
