Corrosive, abrasive and high temperature resistant resins have the potential to damage the screw and barrel screw unconsciously. For example, some engineering materials, thermoplastic elastomers, and biopolymer materials sometimes form a corrosive environment. In addition, reinforcing materials (such as glass fibers, glass spheres, etc.), certain fillers, and additives are abrasive.

To avoid affecting production efficiency and product quality, processors must closely monitor the hazards that these materials can cause to equipment. In order to maintain high processing standards, it is necessary to establish a preventive maintenance program (hereinafter referred to as the "PM" program). When necessary, the screw and barrel should be inspected and measured, and the screw pulled out and reinstalled or replaced, as minimal wear can affect product quality.

Protecting equipment from corrosive and abrasive resins is best done by choosing the right material to make the screw and barrel. The wear-resistant barrel and screw are manufactured to cope with corrosive, abrasive and high-temperature resistant melts, and the processing cost is about 3-4 times higher than that of the standard polyolefin screw. This is because the price of the wear-resistant alloy is relatively expensive and difficult to process. But they offer a longer service life and longer intervals for repairs.
