Description

 

UHMW-PE dock bumpers and pad has the following advantages:

  - good tensile strength
-good impact intensity
-super compression strength
-good breaking elongation

-15 Percent the weight of steel pads

-Chemically inert, serviceable from 180° F to - 250° F

-Corrosion, chemical, wear and moisture resistant.

-Non-stick surface, easy to clean
