SIS(Styrene-isoprene-styrene block copolymer)
PROPERTIES AND APPLICATIONS Styrene-isoprene block copolymers (SIS) are large volume, low priced commercial thermoplastic elastomers (TPE) which are produced by living ionic copolymerization by sequentially introducing styrene, 2-methyl-1,3-butadiene (isoprene), and styrene into the reactor. The styrene content typically varies between 15 and 40 percent. When cooled below the melting point, SIS’s with a low styrene content phase-separate into nano-sized polystyrene spheres imbedded in an... -
SEBS(Styrene Ethylene Butylene Styrene)
PROPERTIES AND APPLICATIONS Styrene-ethylene-butylene-styrene, also known as SEBS, is an important thermoplastic elastomer (TPE) which behaves like rubber without undergoing vulcanization.SEBS is strong and flexible, has excellent heat and UV resistance and is easy to process. It is produced by partial and selective hydrogenating of styrene-butadiene-styrene copolymer (SBS) which improves the thermal stability, weathering and oil resistance, and makes SEBS steam sterilisable.However, hy... -
SBS(styrene –butadiene block copolymer)
PROPERTIES AND APPLICATIONS Styrene-butadiene block copolymers are an important class of synthetic rubbers. The two most common types are linear and radial triblock copolymers having rubber center blocks and polystyrene end blocks. SBS elastomers combine the properties of a thermoplastic resins with those of butadiene rubber. The hard, glassy styrene blocks provide mechanical strength and improve the abrasion resistance, while the rubber mid-block provides flexibility and toughness. In m...
