摘要:
A castable polyurethane elastomer comprising the polymerization reaction product of a polyurethane prepolymer and 2,3-bis(hydroxymethyl) bicyclo [2,2,1] heptane as a chain extender. The elastomer has an advantageously low rebound property, which makes it particularly useful in shock absorber and anti-vibration mounting applications.
