Title:
URETHANE COMPOSITION FOR STEERING WHEEL
Document Type and Number:
Japanese Patent JPS6438415
Kind Code:
A
Abstract:

PURPOSE: To obtain a urethane composition which gives polyurethanes for steering wheels with low porosity and a homogeneous skin layer and comprises the reaction products of various components such as specific graft-polymer dispersions, specified organic polyisocyanates, foaming agents, chain extending gents, catalysts, surfactants.

CONSTITUTION: A urethane composition for steering wheels is obtained from the reaction products of various components such as (A) a mixture of graft- polymers in polyols(mixture), (B) organic polyisocyanates selected form the group comprising isocyanate propolymers obtained by reacting a mixture of 4,4'-diphenylmethane diisocyanate, dipropylene-glycol and polyoxypropylen-glycol with a molecular weight of about 420, polyme-thylenepolypheylene polyisocyanate polymers containing about 55% diphenylmethane diisocyante, (C) foaming agents, (D) chain extending agents and (E) catalyst, surfactants and optionally flame retardants, fillers, ultraviolet-absorbing agents, etc.
