摘要:
An airtight elastomeric laminate for tyres, wherein said laminate comprises at least two superposed layers of elastomer: a first layer, consisting of a composition based on at least one thermoplastic elastomer comprising polystyrene and polyisobutylene blocks, the amount of thermoplastic elastomer comprising polystyrene and polyisobutylene blocks being included within a range of more than 50 to 100 phr (parts by weight by 100 parts by weight of elastomer); a second layer, consisting of a composition based on at least one diene elastomer, the amount of diene elastomer being included within a range of more than 50 to 95 phr, and on at least one styrene thermoplastic elastomer (TPS), the amount of styrene thermoplastic elastomer being included within a range of from 5 to less than 50 phr.
摘要:
The present invention concerns a tyre comprising a tread, a crown with a crown reinforcement, two sidewalls, two beads, a carcass reinforcement anchored to the two beads and extending from one sidewall to the other, characterised in that the tread comprises a composition made from at least one diene elastomer, at a level of between 35 and 99 phr (parts by weight per hundred parts of elastomer), a thermoplastic elastomer, at a level of between 1 and 65 phr, said thermoplastic elastomer being a block copolymer comprising at least one optionally hydrogenated butadiene-styrene random copolymer elastomer block and at least one styrene thermoplastic block.
摘要:
The invention relates to a tyre provided with an inner layer having improved sealing, said layer comprising at least one rubber composition containing at least one or more diene elastomers, the total content thereof being between 1 and 99 pph (parts per hundred parts of elastomer), one or more thermoplastic elastomers including a polyisobutylene block, the total content thereof being between 1 and 99 pph, optionally between 0 and 120 pph of a reinforcing filler, and a cross-linking system.
