摘要:
Tyre having an inner and/or outer surface comprising a receiving region, an adhesive layer deposited on said receiving region and a protective film deposited on said adhesive layer, characterized in that said adhesive layer is made from a block thermoplastic elastomer (TPE) comprising an elastomer block made from a diene elastomer having a molecular (or mass) unsaturation level greater than 0%.
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 invention relates to a composite reinforcement (R-2) that auto-adheres, during curing, to a diene rubber matrix. Said reinforcement can be used as a reinforcing element for a pneumatic tyre and comprises: at least one reinforcing thread (20), for example a carbon steel cord; a layer (21) of a thermoplastic polymer composition, covering each thread individually or collectively as a plurality of threads, comprising a thermoplastic polymer having a positive glass transition temperature and an unsaturated, functionalised thermoplastic styrene elastomer having a negative glass transition temperature, said elastomer carrying functional groups selected from the groups epoxide, carboxyl, anhydride or acid ester. The invention also relates to a method for producing such a composite reinforcement, and to a semi-finished rubber product or item, especially a pneumatic tyre, including such a composite reinforcement.
摘要:
A tyre tread includes a cellulose-based filler material placed in a cavity of the tread. The filler material includes a blend of a degradable cellulose-based thermoplastic and an unsaturated thermoplastic elastomer.
摘要:
The invention relates to a tyre comprising a tread, a crown with a bracing ply, two sidewalls, two bead fillers, and a casing ply attached to the two bead fillers and extending from one sidewall to the other, wherein the tread comprises at least one thermoplastic elastomer, said thermoplastic elastomer being a block copolymer comprising at least an elastomer block of the optionally hydrogenated butadiene-styrene statistical copolymer type, and at least an styrene-type thermoplastic block, and the total value of thermoplastic elastomer being between 65 and 100 pce (parts by weight per hundred parts of elastomer).
