HDPE is resistant to corrosive agents, impacts and abrasion. It is suitable for cases as well as guards for equipment subject to corrosion.

UHMW is impact- and abrasion-resistant and has a low friction coefficient. It is recommended for coatings, chain guides and concentrate chutes.

Fiber-reinforces plastic (FRP)
Lightweight and resistant, FRP is the perfect material for structural applications in highly corrosive environments such as concentration plant guards.

Slick, resistant to compression, impacts and, nylon is mainly used to manufacture rings and wear plates.
