Flame resistant rubber based articles
Hose embodiments include an inner tube, a reinforcement layer disposed outwardly adjacent the inner tube, and an outer cover layer disposed outwardly adjacent the reinforcement layer. One or more of the inner tube and cover layer may be based upon a curable composition having EPDM, a filler package, and a sulfur curative, and after curing, the hose embodiments meet the testing requirements of the UL 94 standard. In some cases, the inner tube is based upon the curable composition, while in some other cases, the cover layer is based upon the curable composition. Yet, in other cases, the inner tube and the cover layer each is based upon the curable composition. In some aspects, the curable composition includes the EPDM in an amount of from 10% to 30% by weight, or even in an amount of from 30% to 80% by weight.
Wrapped V-belt
The present invention relates to a wrapped V-belt including: a tension member layer including a tension member; a tension rubber layer laminated on the tension member layer at a belt outer peripheral side; a compression rubber layer laminated on the tension member layer at a belt inner peripheral side; and an outside cloth covering an entire outer surface of the belt, in which the compression rubber layer includes a first compression rubber layer laminated at the belt outer peripheral side and a second compression rubber layer laminated at the belt inner peripheral side, and the tension rubber layer has a rubber hardness that is higher than a rubber hardness of the second compression rubber layer and lower than a rubber hardness of the first compression rubber layer.
Transmission V-belt
A power transmission V-belt includes a tension member, an adhesion rubber layer in which at least part of the tension member is embedded, and a tension rubber layer and a compression rubber layer stacked via the adhesion rubber layer. A rubber hardness of the tension rubber layer is smaller than a rubber hardness of the compression rubber layer. In the adhesion rubber layer, a rubber hardness on a tension rubber layer side relative to the tension member is smaller than a rubber hardness on a compression rubber layer side.
FRICTION TRANSMISSION BELT
A friction transmission belt includes a compression layer forming a pulley contact portion, the compression layer includes an inner layer formed from a rubber composition and an outer layer provided on a pulley contact side of the inner layer and formed from a fiber member, and a ratio (M10 modulus/M50 modulus) of an modulus at 10% elongation in a belt longitudinal direction (M10 modulus) to an modulus at 50% elongation in the belt longitudinal direction (M50 modulus), of the rubber composition, is not less than 1.5.
Electrically conductive belt
A conductive anti-static drive belt includes a first or drive surface having a plurality of tooth formations therein with a land portion formed between each adjacent pair of teeth. The drive surface is provided by a fabric layer having electrically conductive properties. The fabric layer has an interior surface opposite the drive surface. A second surface is provided opposite the drive surface. The second surface is provided by a polymeric body that conforms to and is mated with the interior surface of the fabric layer. At least one tensile reinforcement member is at least partially encased in the polymeric body and extends along the interior surface of the fabric C layer at each land portion throughout a loop formed by the belt. A conductive strand is at least partially encased in the polymeric body and extends along the interior surface of the fabric layer at each land portion.
COMPOSITE AND METHOD FOR MAKING
A composite includes a first layer of a first fluoropolymer; a second layer of at least one ply of a reinforcing fabric overlying the first layer; and a third layer of a second fluoropolymer overlying the second layer opposite to the first layer, wherein the first layer, the third layer, or combination thereof have an outer surface that is defect free; wherein the composite has a continuous length of at least about 3 meters. Embodiments of such composites can find applications, for example, as processing aids for an electronic device, a food, a polymer, insulating an electrical device, or heat sealing a polymer.
