Thermoplastic Elastomer SIS HEXAS EL-9102

Hua Whakataki

Styrene-butadiene me te styrene-isoprene block copolymers (SBR), e mohiotia ana ano ko te styrene-butadiene-styrene (SBS) me te styrene-isoprene-styrene (SIS), e rua nga copolymers triblock e hono ana he poraka polystyrene i ia pito o te mekameka ngota. me te raupapa butadiene, isoprene ranei kei waenganui.Ko te SBS me te SIS he elastomers thermoplastic, he whakakotahitanga e whakaatu ana i te elasticity me te resilience o te rapa butadiene me te rapa isoprene (rapa maori) me te kaha o te polystyrene ki te whakarewa me te hanga i raro i te awe o te wera.
