PVC Alloys and Blends
The flexible PVC products are nowadays subjected to very demanding service conditions that limit their long-term usefulness. The shortcomings associated with the use of conventional PVC compounds can be overcome by addition of different polymer such as Nitrile rubber. Other polymers such as Thermoplastic Urethane and Olefinic copolymers are also used to impart special properties in PVC. The PVC / Nitrile blends can improve the following properties of flexible PVC compounds:
» Oil, solvent, gas and fat resistance
» Abrasion resistance, tensile and tear strength
» Compression set
» Plasticizer migration and extraction
» Low temperature flexibility after aging
» Provides a rubber like appearance and feel to PVC
Thermoplastic Elastomers (TPE)
TPEs are a family of polymers that can be repeatedly stretched without permanently deforming the shape of the part. Unlike rubber-like elastomers, they do not require curing or vulcanization, as they are true thermoplastics. Thermoplastic elastomers (TPEs) may be processed by conventional thermoplastic techniques such as injection molding, extrusion and blow molding. Thermoplastic elastomers have replaced rubber in many applications, most importantly the automotive industry. There are six main thermoplastic elastomer groups found commercially; styrenic block copolymers, polyolefin blends (TPOs), elastomeric alloys, thermoplastic polyurethanes (TPUs), thermoplastic copolyesters and thermoplastic polyamides. Uses: Automotive Applications, Seals, General Purpose, Overmolding, Consumer Applications, Gaskets, Medical/Healthcare Applications, Automotive Interior Parts, Flexible Grips, Handles, and more...
