Abstract

The present disclosure relates to sprayed polyether and polyester polyurethane elastomeric articles and related methods of producing such elastomeric articles. More specifically, the present invention provides sprayed polyester polyurethane elastomer articles exhibiting excellent tensile and tear strength, excellent elongation properties, and improved wear resistance, with an adjustable tensile modulus.

Description

technical field [0001] This application generally relates to sprayed polyurethane elastomers, methods for producing articles using such sprayed polyurethane elastomers, and articles resulting therefrom. Background technique [0002] Spray polyurethane elastomers are used in many applications, including high-end products in automotive and other related fields, for purposes such as interior materials, instrument panel skins, and seat skins. Typically, spray polyurethane elastomers are based on two-component polyurethane systems formulated from polyol resins and isocyanates or isocyanate prepolymers. Traditional spray elastomers can be divided into three main categories, namely spray polyurethane, spray polyurea, and hybrid systems derived from polyurethane / polyurea using polyether polyols, polyamines or combinations. Resin compositions typically contain low viscosity polyols and additives such as catalysts, surfactants, chain extenders, crosslinking agents, fillers, and the l...
