Styrene IsopreneStyrene Block Copolymer

SIS, short for styrene-isoprene-styrene block copolymer, is a thermoplastic elastomer.

SIS Rubber Characteristics
1. High Elasticity: The alternating arrangement of soft and hard segments in the SIS rubber molecular chain gives it high elasticity and excellent resilience.
2. Excellent Tensile Strength: The molecular structure of SIS makes it resistant to breakage under tension, resulting in high tensile strength.
3. Excellent Aging Resistance: SIS rubber has a long service life and is not susceptible to aging even after prolonged outdoor use.
