Below is a list of Urethane Bumpers manufacturers from Sioux City, Iowa. Urethane bumpers are protective parts that function to absorb shock or to impede contact. Since they are formed from urethane, which is elastomer containing urethane carbamate links, this type of bumper has many advantages over conventional elastomers and plastic materials. Some examples of these benefits include high abrasion and impact resistance nose abatement properties, high load bearing capacities and a broad hardness range.
