Styrene–Ethylene–Butene–Styrene block copolymer（ SEBS) is a white particle with polystyrene as the terminal segment and polybutadiene hydrogenated The obtained ethylene–butene copolymer is a linear three-embedded copolymer of the middle elastic block SEBS does not contain unsaturated double bonds, so it has good stability and durability. Aging properties.
Benzene Ethylene–Ethylene–Butene–<span style="font-family: Characteristics and uses of Styrene block copolymer (SEBS):
SEBS It has excellent aging resistance, has both plasticity and high elasticity. It can be processed and used without vulcanization, and leftover materials can be reused. It is widely used in the production of high-grade elasticity. Body, plastic modification, adhesive, lubricating oil tackifier, filler and sheathing material for wires and cables, etc.
SEBSIt has good UV stability, oxidation resistance and thermal stability, so it can also be used in asphalt for roofs and road construction.
SEBShas good compatibility with paraffin, so it can be used as a flexible surface coating for paper products.
SEBSIt is temperature insensitive when there is no obvious shear flow when heated, so it can be used asIPN‘s template. (The basic principle of IPN: two immiscible polymers can achieve entanglement The mutual penetration of the knot segments allows the two immiscible polymers to be cross-linked through covalent bonds“Lock“together.)
SEBSThe organic solution of the oil blend can replace natural latex in the manufacture of surgical gloves and other products, due toSEBSIt does not contain unsaturated double bonds and has high purity. It has the following two advantages:(1) span>Good antioxidant and ozone resistance;(2)Natural rubber contains proteins that can cause dangerous allergic reactions in some patients, but this blend does not.
