摘要:
A vulcanizable adhesive composition, which comprises 45-75% by weight of phenol resin, preferably a mixture of novolak-type and resol-type phenol resins, 5-25% by weight of halogenated polymer, and 10-30% by weight of a metal oxide, can improve an interlayer adhesiveness between the acrylic rubber and metal without surface treatment of metal, such as a chemical treatment, e.g. zinc phosphate treatment, etc., blast treatment, or primer treatment, and thus can be effectively used in the production of a metal/adhesive layer/acrylic rubber composite.
摘要:
A fluoroelastomer latex composition stabilized against settling with from 1 wt% up to 50 wt% of a natural or synthetic pulp, comprising fibers having an average length of from 0.1 mm to 13 mm, uniformly dispersed therein.
摘要:
Tire tread containing rubber composition(s) comprising diene elastomer(s) (I), inorganic reinforcing filler (II), coupling agent (III) and plasticizers (IV), in which (I) contains 30 phr butyl rubber (parts by weight per 100 parts elastomer) and (IV) is a triester of glycerol and 12-22C unsaturated fatty acid. Independent claims are also included for (1) a method for the production of Tire tread with better adherence on wet roads, by mixing components (I)-(IV) in a mixer until the temperature of the mix reaches 130-200[deg]C, adding a crosslinking system, mixing at not above 120[deg]C and extruding or calendering the composition as a tire tread (2) tires with tread as defined above.
摘要:
The present invention provides a process for preparing a filled halobutyl elastomer, which includes mixing a halobutyl elastomer with at least one mineral filler and at least one dry liquid modifier and optionally curing the filled elastomer with sulfur or other curative systems. Filled halobutyl elastomers prepared according to the present invention possess improved levels of filler dispersion which results in a reduction in the hardness of the compound and an increased tensile strength.
