There are a wide array of Applications for Rigid PVC. Here are Some:
PVC is a tough and rigid plastic material that can be worked under ambient conditions. It is best suited with injection molding and can work well with additives such as stabilizers, processing aids, pigments, lubricants, impact modifiers, and fillers. Some of the other major advantages include:
It is important to process the material at the correct mold temprature to avoid the production of hydrochloric acid and decomposition. Some other limitations associated with PVC are:
1. What and how is PVC material made?
Ans. PVC is made by suspension, bulk, solution, and emulsion polymerization of vinyl chloride monomer utilizing free radical initiators. The most common way of extracting or obtaining a vinyl monomer is reacting ethylene with oxygen and hydrogen chloride over a copper catalyst.
2. Is PVC a waterproof material?
Ans. The waterproofing ability of PVC highly depends on the formula. PVC coating on other materials is waterproof and resistant to dirt, chemicals, salt, mildew, oil, and UV rays and provides the material additional strength and durability.
3. Which one is better? Polyester or PVC
Ans. Both the materials have their own pros and cons. PVC is fire and water-resistant and very temperature stable; conversely, polyester is highly flammable but resistant to many atrocities like chemicals, water, wrinkles, stretching.
PVC is used for applications like clothing, roofing membranes, upholstery, flexible hoses, pipes, ceiling tiles, and insulation for electrical cables. Talking bout Polyester, its best applications are synthetic fiber, plastic bottles, power belting, floppy disk liners, sails, high strength thread/ropes, etc.
4. Is PVC biodegradable?
Ans. The original PVC plastic is not biodegradable, but many manufacturers can provide additional solutions with materials that make PVC biodegrade faster in landfills without affecting its inherent properties.
5. What is the repeat unit of PVC?
Ans. The basic repeat unit of the PVC is [-CH2-CHCI-].
