A hose includes an outer cover layer and at least one ply disposed inward from the outer cover layer, characterized in that the outer cover layer is a shrink sleeve, and where the at least one ply is formed from a reinforced silicone rubber sheet which includes a reinforcement. The hose may further include an inner layer disposed within the at least one ply, and which defines a lumen. The shrink sleeve may be a polyolefin shrink sleeve. The layers are tensioned together with the shrink sleeve. The hose may be prepared by a shrink tension method without the use of a tape wrap. A method of preparing the above hose may include wrapping the inner layer around a mandrel, wrapping the at least one at least one ply around the inner layer, pulling the shrink sleeve over the at least one at least one ply, and vulcanizing the hose.

An ethylene-vinyl alcohol copolymer composition is substantially free from coloration, and contains: (A) an ethylene-vinyl alcohol copolymer; (B) a polyamide resin; and (C) an iron compound; wherein the iron compound (C) is present in an amount of 0.01 to 20 ppm on a metal basis based on the weight of the ethylene-vinyl alcohol copolymer composition.

The invention relates to a film comprising an optionally multilayer carrier layer; wherein one surface side of the carrier layer has been modified over part of its area either by surface activation or by printing with a print medium, such that the surface side has modified regions and unmodified regions; wherein the modified regions and the unmodified regions are coated over part or all of the area by a release material; and wherein the strength of adhesion of the release material to the carrier layer in the modified regions is different compared to the adhesion of the release material to the carrier layer in the unmodified regions.

Golf balls having covers made of thermoplastic polyurethane compositions are provided. Multi-piece golf balls can be made. Polyurethane primer coatings and polyurethane top-coatings are applied to the thermoplastic polyurethane cover. Different coating methods can be used. Isocyanate-rich and polyol-rich polyurethane coatings can be applied. In one embodiment, the golf ball can be treated with a multi-functional isocyanate prior to applying the coatings. The polyurethane cover composition and surface coatings can further include catalysts, ultraviolet (UV)-light stabilizers, and other additives. Heat is used to cure the coatings. The coating methods have many benefits and the finished balls have good physical properties.

Disclosed are a diaphragm for a sound generating device and a sound generating device. The diaphragm comprising at least one elastomer layer, wherein the elastomer layer is made of an ethylene propylene diene monomer; and the ethylene propylene diene monomer is formed by polymerizing three monomers, the three monomers being an ethylene monomer, a propylene monomer and a non-conjugated diene monomer respectively, a mass ratio of the ethylene monomer to the propylene monomer ranging from 0.25 to 4, and content of the non-conjugated diene monomer being 1%-15% of total content of the ethylene monomer and the propylene monomer. The ethylene propylene diene monomer has excellent high-temperature resistance and thermo-oxidative aging resistance; and after the rubber is made into the diaphragm, the diaphragm is capable of working in a high-temperature environment for a long time, maintaining not only excellent elasticity but also excellent anti-fatigue characteristic, thereby possessing excellent reliability.
