DW 400 is a skived Ultra High Molecular Weight Polyethylene film (UHMW), available in both black and natural, that has been put through a densification process to enhance the physical properties and surface smoothness.

DW 400 has extremely high abrasion resistance, exceeding the abrasion resistance of steel in some cases. By adding the densification to the process, the DW 400 has increased tensile values as well as increased toughness. UHMW offers a broad range of chemical resistance and a low coefficient or friction making it an extremely versatile engineering material for many severe service applications. DW 400 can be used in chemical, fuel and hydraulic hoses, linings for chutes to decrease friction and wear as well as a great material used in conjunction with rubber belting surfaces.
