vvSIn the modern world plastic parts are all around us, from the computer cabling that connects us to the world wide web, to the electrical wiring and conduits that wind around our houses and businesses, to the infinitely numbered plastic pieces on the dashboards of our vehicles. The majority of plastics are made from PVC (Polyvinyl Chloride) and manufactured by PVC compounders in facilities in many countries and across the US.
Chemical engineers are able to change the chemical properties of rigid plastic blends to create rigid PVC compounds that maintain their shape or flexible PVC that if often used for soft tubing or other bendable parts. The uses for PVC plastics really are endless and include residential, commercial and industrial products including:
Automotive Parts - shifters, gaskets for doors, seals for windows or sun roofs, console molding, trim, wiring
Industrial - handles, grips, hoses, tubing, knobs, suction cups, grommets, parts
Medical - tubes, bendable tubes, food IVs. Plastics found in the medical field are made from medical grade PVC plastics developed for safety and sanitation.
Building/Construction - window stripping, seals for windows, outside trim
Wires & Cabling - appliance wiring, communications cabling, automotive cabling and wires
Electric - cords, harnesses for wires, boots for battery terminals, shields
These industries can manufacture components without having to use metals, glass, and other materials. This allows factories create lighter, cheaper products. Another benefit of plastic blends is their resistance to corrosion.
Environmental concerns in recent years have spawned the creation of chemical free flexible PVC compounds that are safer for use in children's toys and vinyl compounds involved in food processing.
