摘要:
The present invention has its object to provide a high performance studless tire, which has both good braking force and high handling stability on ice or snow, at higher productivity and at a lower price for customers. The studless tire comprises a tread made of a rubber composition that contains 0.5 to 5.0 parts by mass of a fatty acid and/or a derivative of the fatty acid per 100 parts by mass of a rubber component.

A sealing plate for a prismatic secondary battery includes a pair of mouths for attaching a negative and positive electrode terminals, one mouth being formed near one end in a longitudinal direction of the sealing plate, and the other mouth being formed near the other end, coining areas used for positioning of an insulating member and formed around the pair of mouths on a front face of the sealing plate, a gas release valve and an electrolyte pour hole formed between the pair of mouths, and grooves formed between the respective coining areas and the long side edge of the sealing plate. The groove has a smaller depth near the gas release valve than the depth near the coining area. Even when the sealing plate is produced through forging, the front face has good flatness and the coining areas are unlikely to have a sink mark or a shear drop.

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 CO2 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/cm3 or more.

The present invention relates to a rubber composition for a base tread, containing: a rubber component; and a mixture of a zinc salt of an aliphatic carboxylic acid and a zinc salt of an aromatic carboxylic acid, wherein the rubber component contains natural rubber and butadiene rubber, the butadiene rubber content being 10 to 90% by mass per 100% by mass of the rubber component, and the mixture of a zinc salt of an aliphatic carboxylic acid and a zinc salt of an aromatic carboxylic acid is contained in an amount of 1 to 10 parts by mass per 100 parts by mass of the rubber component.
摘要:
A laminated seamless belt having at least a base layer and an outer layer. The base layer contains a polyester thermoplastic elastomer as its main component. The base layer has a volume resistivity set to not less than 1.0×106(Ω·cm) nor more than 1.0×1011(Ω·cm). A volume resistivity of the outer layer is set to not less than 1.0×1011(Ω·cm) and not less than 10 times as large as that of the base layer. The base layer and the outer layer are formed by laminated extrusion.
