How it works
What Makes TecsPak Different
More energy per kilogram – and it lasts.
A Tougher Elastomer
TecsPak is a patented thermoplastic elastomer (TPEE) first developed for heavy railway draft gear. Its shape and Miner’s processing set exactly how it stiffens as it compresses, so a bumper can be matched to the load.
Lasts Far Longer
In comparative tests TecsPak lasted 20 times longer than urethane and 10 times longer than rubber. It is inert to dirt, oil, hydraulic fluid, petrol and diesel, and works from about −40 °C to +49 °C.
Why TecsPak bumpers
Designed to the Load
Engineered Rate
Shape and material tuned to the load rate you need.
Axial or Radial

Emergency Rated
Rated energy plus an emergency-stop rating for each size.
Custom
Special durometers, sizes and colours available.
How to choose
Sizing a Bumper
Energy
Work out the energy to absorb from the moving mass and speed.
Force
Check the peak force the structure can take.
Space
Free height and bulge at solid height must fit.
Temperature
TecsPak stiffens in the cold and softens in heat – tell us the range.
