1. Polypropylene (PP) and polyethylene (PE):
bimetallic screw barrel are adaptable to common thermoplastics such as polypropylene and polyethylene. These plastics typically melt at low to slight processing temperatures, and their extrusion and molding tactics are fairly simple. For this kind of fabric, screw and barrel design commonly specializes in presenting uniform heating and combining to make certain strong extrusion of the material.
2.Polyvinyl chloride (PVC):
PVC is a special plastic that requires better processing temperatures, and bimetallic screws and barrels can offer better put on resistance and thermal balance to cope with its unique melting requirements. These screws and barrels want to have better warmth transfer talents and exact mixing homes when processing PVC.
3. Polystyrene (PS) and polycarbonate (PC):
Plastics inclusive of PS and PC usually require better processing temperatures and accurate thermal balance. Bimetallic screws and barrels require unique surface coatings or fabric combinations while processing these substances to evolve to the processing requirements underneath excessive temperature and strain and ensure solid extrusion and molding of plastics.
4. Polyamide (PA):
Polyamide plastics including nylon require higher melting temperatures and pressures. For these substances, bimetallic screws and barrels usually use special floor treatments and alloy substances to address their better processing requirements and ensure uniform blending and stable extrusion of plastics.
5. Thermoplastic elastomer (TPE) and thermoplastic polyurethane (TPU):
The elasticity and softness of these substances require better thermal manipulate and combining abilities of the screw and barrel. Bimetallic screws and barrels are regularly designed with those traits in thoughts to make sure material balance for the duration of extrusion and molding.
