TPE 鞋底改性 JSR RB810 亚光 雾面剂 高透明 增韧级 合成橡胶 (CAS No.None)

Product Name:JSR RB810 TPE

English Name:JSR RB810 TPE

Aliases:RB810 thermoplastic elastomer, styrene-butadiene block copolymer, PVC toughening modifier, matting agent

Physical Properties:This product is a styrene-butadiene block copolymer (SBC), supplied as transparent to translucent pellets. Specific gravity approx. 0.91, melt flow index (190°C, 5kg) approx. 8g/10min, styrene content approx. 18%. It features excellent transparency, low haze, flex-cracking resistance and tear strength, with good compatibility with SBS, PVC and various rubbers, improving melt flow and processability.

Uses:Mainly used as a modifier for SBS shoe soles: adding 15%~25% eliminates flow marks and produces a uniform matte surface without spray coating, reducing production costs while improving wet skid resistance, flex resistance and elasticity. It is also effective as a PVC modifier at 3%~5% loading to eliminate flow marks, retain plasticizer and enhance hand-feel. Additionally, it serves as a good upgrading agent for various rubbers, improving flow, weather resistance, extrusion performance and chemical resistance, especially suitable for high-hardness compounds above Shore A90.

Technical Specifications:

Appearance: transparent to translucent pellets, free from mechanical impurities.

Styrene content: approx. 18%, low crystallinity with high clarity.

Melt flow index: approx. 8g/10min (190°C, 5kg), excellent flowability.

Recommended loading: 15%~25% for SBS modification, 3%~5% for PVC modification.
