SIS is a class of styrene-isoprene-styrene triblock copolymers produced via proprietary sequential anionic polymerization. Most SIS products are of linear structure, with different amount of diblocks. It usually appears as porous particles with outstanding melt processability and thermal stability. SIS is mainly used in hot melt pressure sensitive adhesives, sealants and polymer modification....
TPU, the full Chinese name of TPU, is a thermoplastic polyurethane elastomer, which is a high molecular compound formed by the reaction and polymerization of diisocyanate molecules such as diphenylmethane diisocyanate (MDI) or toluene diisocyanate, macromolecular polyols and low molecular Polyols (chain extender)....
TPR material is a kind of raw material based on thermoplastic styrene butadiene rubber (such as SBS, SEBS), and then mixed with resin (such as PP, PS), filler, plasticizer and other functional additives....
With the development of science and technology, TPE materials will be used more and more widely. Because TPE has the advantages of both rubber and plastics, it has opened up a new application field for the rubber industry....
SBS has good tensile strength, elasticity and electrical properties, small deformation, good flexion and resilience, and large surface friction. The resistance to ozone, oxygen and ultraviolet radiation is similar to that of styrene butadiene rubber, with excellent air permeability, low temperature resistance and wet skid resistance....
SIS thermoplastic elastomer is mainly used as packaging bag, medicine field, double-sided tape, oil resistant label, etc; It is commonly used in adhesives, sealing materials, shoe materials, coatings, wire and cable sheaths, sealing rubber, molding of general daily necessities, medical or food materials, jelly candles, transparent candles, etc. it can also be used as phase solvent of engineering plastics....
