SIS YH-1209, chemical name: Styrene-Isoprene Block Copolymer. Physical form: White or light-colored porous round bars/flakes.
SIS Synthetic Rubber Features:
Thermoplastic: Melt-processable within a wide processing temperature range (200-250°C);
High Elasticity: Elongation at break reaches 500%-800%, with excellent resilience;
Adhesion: Highly bonded to a variety of materials (such as plastics, metals, and rubber), making it particularly suitable for the manufacture of pressure-sensitive adhesives and hot-melt adhesives;
Environmentally Friendly: Non-toxic and solvent-free, it meets environmental standards.
SIS RUBBER Main Application Areas
Adhesives and Pressure-Sensitive Adhesives: The core raw material for hot-melt pressure-sensitive adhesives (HMPSAs), used in labels, tapes, sanitary napkins, diapers, and other applications. They are solvent-free, environmentally friendly, and low-energy.
Plastic Modification: Blending with PE, PP, and other materials improves impact resistance and flexibility.
Asphalt Modification: Enhances asphalt's low-temperature crack resistance and high-temperature stability.
Other Applications: Flexible printing plates, coating toughening, footwear, and medical supplies.
