Impact Protection Bumpers

The Duramax Difference. Quality you can trust.

Our products are only manufactured of EPDM (Ethylene Propylene-Diene-Monomer) Rubber which can last 4X longer than SBR or butyl fenders.
  • Unaffected by ozone and has a greater resistance to sunlight and oxidation.
  • Highly resistant to seawater, steam and many chemicals.
  • Withstands temperatures as high as 150° F and as low as - 60° F.
heat chart
Material: EPDM (Ethylene Propylene-Diene-Monomer)
Range of Service: -60° F to 150°F (continuous duty)
Durometer: 70±5 shore “A” scale
Compression Recovery: Instantaneous recovery of 90-95% is observed over a 20,000 to 200,000 lb. static load on one foot sample lengths of designated cross-sections. Samples have been compressed 70% by overall height without any damage.
Impact Resiliency: As a function of fendering cross-section, high reaction loads with large energy absorptions have been transmitted with no damage experienced.
Shear Strength: For rubber and rubber-like materials, average shear strength is usually taken as 50% of tensile or compressive strength as per application.
Water Absorption: Negligible.
Life: Excellent for weather condition in ozone.
