Energy Absorbing Padding for Sports Application |
摘要 |
A method of producing a viscoelastic polyurethane foam coating in which a polyisocyanate is reacted with a polyol to form a prepolymer. The prepolymer is reacted with a polyol having at least one pendant carboxylic acid group to form a prepolymer with a pendant carboxylic acid group. The prepolymer with a pendant carboxylic acid group is neutralized with a tertiary amine and then reacted with water or an organic or inorganic polyamine. An energy absorbing unit in which the coating produced by the above method is provided on a viscoelastic polyurethane foam layer.
