Abstract: A flexible hose construction with kink, crush, and burst resistance. The hose is constructed of a tubular member and a reinforcement strip at least partially embedded in the tubular member. The reinforcement strip is wound in a helical pattern encircling a central lumen of the tubular body. The material forming the reinforcement strip has a greater initial modulus than the material forming the tubular member.

Abstract: The present invention is directed to the incorporation of functionalized polyethylenes, in amount of about 1% to 95% by weight based upon the weight of the total crosslinkable material, into ethylene alpha olefin elastomers, such as EPDM elastomer compositions, which are crosslinked by peroxides, which results in improved properties, such as hardness and modulus of elongation, and can result in improved higher abrasion resistance, wear resistance, coefficient of friction, tensile strength, and other properties through a broad temperature range, which are beneficial to power transmission products, such as power transmission belts.

Abstract: The present invention is directed generally to track segments for track vehicles and, more specifically, to a track segment having an ethylene propylene diene monomer (EP(D)M) rubber based backer, and a method of making. In one embodiment, the track segment includes an EP(D)M rubber based backer including a rubber compound having 100 phr EP(D)M rubber wherein the diene component is optionally present, a peroxide curing agent, and one or more acrylic and/or methacrylic coagents. The track segment further includes a track pad and a track body. The track pad and backer cooperate with the track body to define the track segment for use in a track for a track vehicle. The EP(D)M rubber based compound provides a desirable balance of low heat build-up under heavy dynamic cyclic compression conditions, and also has a desirable load carrying capability, high heat resistance, and good cut/tear strength in hot climates.

Abstract: A reduced cost elastomeric blend suitable for use in vehicle timing belts and other applications constructed with elastomeric portions having a high HNBR concentration. The blends comprise from about 50 to less than 100 phr of HNBR and from about 0.1 to about 50 phr of lower cost diluent unsaturated nitrile rubber with from about 0.1 to about 30 phr of a heat resistant additive, which may be THERBAN HT. The elastomeric blends may be cured with a peroxide/co-agent cure system. The elastomeric blends may be mixed by a Y-mix method to improve ozone resistance. A timing belt constructed of the elastomeric blend is also taught.

Abstract: A Y-mix cycle has been discovered to achieve proper quality and consistency when mixing heavy fiber loaded compounds within a polymer compound. The Y-mix cycle may include the following steps: (1) mixing a first portion of a polymer with a first component mix that includes at least one filler to create a first blend; (2) mixing a second portion of the polymer (or a portion of a different polymer) with a second component mix that includes at least one fiber to create a second blend; and, (3) mixing the first blend with the second blend to create the polymer compound.
