At NINGBO INNO PHARMCHEM CO.,LTD., we believe in empowering our clients with in-depth knowledge of the materials they use. Thermoplastic Rubber (SBS) YH-815E is a high-performance polymer with a broad spectrum of applications, from enhancing footwear to modifying plastics and improving asphalt. This article aims to provide a detailed look into its properties, advantages, and why choosing a reliable high quality thermoplastic rubber supplier is paramount for success.

The fundamental structure of SBS YH-815E is that of a star block copolymer, composed of styrene and butadiene segments. The specific ratio of approximately 40% styrene to 60% butadiene is key to its performance. This composition grants the material a unique dual nature: the styrene segments provide rigidity, strength, and thermal stability, while the butadiene segments offer flexibility, elasticity, and low-temperature performance. This balanced structure allows SBS to behave like a rubber at ambient temperatures but process like a thermoplastic at elevated temperatures, offering significant processing advantages.

Key properties that make SBS YH-815E stand out include its high tensile strength, reaching up to 24MPa, and a hardness of 89 on the Shore A scale. The low melt flow rate (MFR) of 0.1 g/10min at 200°C and 5kg load indicates good dimensional stability once processed, which is critical for applications requiring precise shapes and minimal post-molding distortion. Furthermore, its excellent low-temperature resistance, air permeability, and wet slip resistance, coupled with its ability to function without added sulfur, make it a versatile and efficient material choice.

The applications for thermoplastic rubber SBS YH-815E are diverse. In the shoe industry, it is prized for its ability to create comfortable and durable soles. For plastic modification, it serves as an excellent toughening agent, improving the impact resistance of various polymers. In the realm of adhesives, it forms the backbone of high-performance bonding agents. Moreover, its utility in asphalt modification leads to roads that are more resilient to temperature changes and wear.

When selecting SBS, the choice of supplier is critical. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing premium SBS grades that meet rigorous quality standards.
