Polyurethane is a unique material that offers the elasticity of rubber combined with the toughness and durability of metal. Because urethane is available in a very broad hardness range it can offer the ultimate in abrasion resistance and physical properties.
Urethanes have better abrasion and tear resistance than rubber materials.
Urethanes offer superior impact resistance, while offering excellent wear properties and elastic memory.
ADVANTAGES TO POLYURETHANE
Abrasion resistant
Parts made of polyurethane will often outwear other materials by a margin of 5 to 50/one when severe abrasion is a factor. It has been proven to be vastly superior to rubber plastics.
Oil and solvent resistant
Polyurethane has excellent resistance to oils, solvents, fats, greases and gasoline.
Enough of the science though, purchase and enjoy.
I also have spring bar removal tool available which I am happy to combine postage with this purchase.
