SUNION Class S-1522 is a premium linear tri-block and pure SI hybrid thermoplastic elastomer that embodies advanced engineering. Synthesized through an anionic polymerization process using styrene and isoprene monomers, S-1522 boasts a compact particle structure with a sophisticated transparent or translucent appearance, reminiscent of high-grade hard plastics. Featuring a composition of 15% styrene and 22% di-block content, this exceptional material offers outstanding advantages including streamlined material flow, enhanced efficiency, and reduced labor costs. These benefits are achieved through the versatile twin screw extrusion modification or direct injection production processes, making S-1522 a superior choice for innovative and cost-effective manufacturing solutions.

Attentions
The S-1522 thermoplastic rubber elastomer, classified as combustible, must be stored away from fire, heat sources, and strong oxidizing agents. Due to its internal double bonds, it is susceptible to cross-linking and cracking when exposed to sunlight or ultraviolet radiation. To preserve its quality, it should be kept out of direct sunlight and strong light exposure, and stored in a cool, dry, and well-ventilated warehouse.
