Title:
エラストマーポリウレタンフォームおよびその生成方法
Document Type and Number:
Japanese Patent JP7459081
Kind Code:
B2
Abstract:
Embodiments of the present disclosure includes an elastomeric polyurethane foam with improved high temperature performance, comprising a reaction product of components including: (a) an isocyanate functional urethane prepolymer derived from one or more prepolymers comprising monomeric diphenylmethane diisocyanate (MDI) and polymeric MDI, and a polyether diol; and (b) an isocyanate-reactive component including: (i) a first polyol in an amount of about 10 to about 70 parts by weight of the isocyanate-reactive component, wherein the first polyol is a propylene oxide or ethylene oxide-capped nominal diol with a number-average molecular weight between about 1000 g/mol and about 9000 g/mol; (ii) a second polyol in an amount of about 0 to about 50 parts by weight of the isocyanate-reactive component, wherein the second polyol is a nominal triol with a high proportion of randomly dispersed ethoxy groups with a number-average molecular weight between about 1000 g/mol and about 8000 g/mol; (iii) a third polyol in an amount of about 0 to about 20 parts by weight of the isocyanate-reactive component, wherein the third polyol is an ethylene oxide-capped nominal tetraol with a number-average molecular weight between about 250 g/mol and about 6000 g/mol; and (iv) a fourth polyol in an amount of about 0 to about 80 parts by weight of the isocyanate-reactive component, wherein the fourth polyol is an ethylene oxide or propylene oxide-capped nominal triol with a number-average molecular weight between about 1000 g/mol and about 13000 g/mol. In one another embodiment, the isocyanate-reactive component also includes an additive package in the amount of about 1 to about 30 that can contain, but is not limited to, blowing agents, catalysts, coloring agents, inorganic filler, and anti-oxidants.
