Waterproof engineered floor and wall planks have a veneer layer bonded with a plastic composite core, and an underlayer, preferably an underlayer of cork.

Methods of manufacturing a conveyor belt (126) include applying a rubber composition (114) to a first side of fabric reinforcement (112) and scattering productive thermoplastic elastomer pellets (106) onto a second side of the fabric reinforcement to produce an uncured belt structure (120). The uncured belt structure (120) is continuous fed into a double belt press (116) to press the productive thermoplastic elastomer pellets (106) together with the fabric reinforcement (112) to produce an uncured belt (128). Uncured belt (128) is then heated in the double belt press (116) to a temperature of at least 300 F. and maintained in the double belt press (116) under a pressure of at least 12 psi and a temperature of at least 300 C. for a residence time of at least 20 minutes to produce a cured conveyor belt (130), which is continuously withdrawn from the double belt press (116).

A laminate of a thermoplastic resin or thermoplastic elastomer composition film and a rubber composition layer, which can be used as an inner liner for a pneumatic tire, with improved adhesive strength at the interface of the thermoplastic resin or thermoplastic elastomer composition film and the rubber composition layer. A laminate comprising a thermoplastic resin or thermoplastic elastomer composition film and a rubber composition layer, the rubber composition containing a rubber component, a condensate of a phenol compound and formaldehyde, and methylene donor and a vulcanizing agent, wherein 2.5-40% by mass of the rubber component is butyl rubber or halogenated butyl rubber, the content of the condensate is 0.5-20 parts by mass per 100 parts by mass of the rubber component, and the content of the methylene donor is 0.25-200 parts by mass per 100 parts by mass of the rubber component.

A conveyor belt includes a cover layer defining a load carrying surface, a pulley engaging layer disposed parallel to the cover layer, and a carcass containing a reinforcement layer, where the carcass disposed between the cover layer and the pulley engaging layer. The cover layer is formed by curing an admixture containing at least a cross-linkable functionalized polyethylene and polyethylene polyolefin. According to the disclosure, the cured admixture is effectively maintained within the cover layer during use of the conveyor belt. In some cases, the load carrying surface maintains a wet clay cleanability value of greater than 3, or even a wet clay cleanability value of greater than 4.4. The cross-linkable functionalized polyethylene may be a cross-linkable oxidized polyethylene. In some aspects, the cross-linkable functionalized polyethylene does not form a polyethylene film upon the load carrying surface.

A method of manufacturing a marine hose that at least a base hose, a sponge layer, a foam rubber layer, and a cover rubber layer. The method comprises the steps of: wrapping a sponge layer around the outside of the base hose; wrapping a foam rubber layer around the outside of the sponge layer, the foam rubber layer containing an unvulcanized foam rubber composition; wrapping a cover rubber layer around the outside of the foam rubber layer; and vulcanizing the wrapped assembly; wherein the foam rubber composition includes a rubber component containing as a main component at least one selected from the group consisting of natural rubber, styrene butadiene rubber, chloroprene rubber, ethylene propylene rubber, ethylene propylene diene rubber, and reclaimed rubber.

Multi-stage composite materials, their preparation, and their uses are described. A composite includes a first layer of a first material contributing to mechanical strength of the composite having a first length, and a second layer of a second material contributing to the mechanical strength of the composite having a second length, wherein the second length is greater than the first length, wherein the second length of the second layer is affixed to the first length of the first layer at both ends of the first and second lengths so that the second layer is spaced apart from the first layer.
