Abstract
PURPOSE: To obtain a flame-retardant foam of low smoke generation with low cost and serving for resource-savings, by highly expanding an ethylne-vinyl acetate copolymer composition highly incorporated with an inorganic filler.
CONSTITUTION: (1) 100pts.wt. of a resin component consisting of an ethylene- vinyl acetate copolymer containing 40W90wt% of vinyl acetate or a blend of the copolymer with another thermoplastic resin (an ethylenic polymer), (2) 50W 500pts.wt. of an inorganic powder (pref. a mixture of aluminum hydroxide and magnesium hydroxide with the particle surface treated with a monoalkoxy organotitanate and having a diameter of 0.1W2μ), (3) 5W50pts.wt. of a blowing agent, (4) 5W30phr of a flame retardant containing 40W80wt% of Br, and (5) 2W20phr of a flame retarding auxiliary are kneaded to form a composition followed by carrying out a crosslinking, in such a condition that the water content of the composition is ≤0.15%, either by adding 0.1W10pts.wt. of a crosslinking agent (e.g., a peroxide) or by irradiating an ionizing radiation, and then expanding at elevated temperature, thus obtaining the objective foam.
USE: Insulating pipe covers, packaging, packing, and cushioning materials, etc.
