Marine Bumper Pads
UHMW PE is a super engineering plastic that is probably not as well known as some other engineering plastics but can out perform its relatives in a number of importantareas.UHMW offers a combination of excellent properties outstanding abrasion resistance,superior impact resistance,non-sticking and self-lubricating properties and excellent mechanical properties,even in cryogenic conditions.UHMW product reduces noise from impact & vibration.It is a self-lubricating material that is chemical,corrosion,and wear-resistant.And its food safe.The weight is light.Life is higher than steel.The wear resistance is 3-7 times of carbon steel and stainless steel.
