摘要:
The present invention provides a rubber composition capable of reducing rolling resistance, and improving abrasion resistance, wet skid performance, and steering stability. A tire having a tread and/or a sidewall using the rubber composition is also provided. The rubber composition of the present invention comprises not less than 10 parts by weight of the silica (1) having an average primary particle diameter of not less than 22 nm and not less than 5 parts by weight of the silica (2) having an average primary particle diameter smaller than 22 nm based on 100 parts by weight of a rubber component, wherein the total amount of the silica (1) and the silica (2) is 15 to 150 parts by weight. The tire of the present invention is prepared by using the rubber composition.
摘要:
It is an object of the present invention to provide a tire rubber composition and a pneumatic tire produced using the rubber composition, which improve mechanical strength, abrasion resistance, rolling resistance, wet grip performance, and dry grip performance in good balance. The present invention relates to a tire rubber composition comprising: a rubber component that contains a modified diene rubber; and a silica component that contains a silica surface-treated with a silane coupling agent, wherein the amount of the modified diene rubber in 100% by mass of the rubber component is 15% by mass or more, and the dispersion ratio of the silica component is 70% or higher.
摘要:
The present invention has its object to provide a rubber composition for a tread which can prevent reversion and can also achieve environmental performance (excellent rolling resistance, response to depletion of oil resources, attention to CO 2 emission), wet grip performance, dry grip performance, handling stability, and durability (abrasion resistance, crack resistance) in a well-balanced manner. The present invention also aims to provide a pneumatic tire using the rubber composition for the tread thereof. The rubber composition for a tread includes a rubber component containing 35% by mass or more of an epoxidized natural rubber; and a white filler, wherein a total sulfur content is less than 1.75% by mass, and a crosslink density is 7.0 × 10 -5 mol/cm 3 or more.

摘要:
The present invention relates to (1) an acrylic resin glove comprising a film having a crosslinked structure, said film being formed of an acrylic resin emulsion, and (2) an internal surface treating agent for acrylic resin glove, comprising an acrylic resin emulsion, and at least one organic filler selected from the group consisting of (meth)acrylic resin micro-particles, polyolefinic resin micro-particles and cellulose beads, each having an average particle diameter within a range from 3 to 10 µm, the content of said organic filler being within a range from 2 to 8% by weight based on the total weight. The acrylic resin glove is superior in fitting and detaching properties and is also superior in washing resistance while maintaining required mechanical characteristics. The internal surface treating agent is useful to obtain an acrylic resin glove having the above-described characteristics by forming a film of this treating agent on the internal surface of the acrylic resin glove, thereby to improve the lubricity of the internal surface of the glove.
