What are the properties and uses of PVC?
Key Properties of PVC Polymer PVC is a very versatile and cost-effective material. Its main properties and benefits include: Electrical Properties: PVC is a good insulation material, thanks to its good dielectric strength. Durability: PVC is resistant to weathering, chemical rotting, corrosion, shock and abrasion.
What is PVC material used for?
Economical, versatile polyvinyl chloride (PVC, or vinyl) is used in a variety of applications in the building and construction, health care, electronics, automobile and other sectors, in products ranging from piping and siding, blood bags and tubing, to wire and cable insulation, windshield system components and more.
What are the properties of polyvinyl?
Some of the most significant properties of Polyvinyl Chloride (PVC) are:
- Density: PVC is very dense compared to most plastics (specific gravity around 1.4)
- Economics: PVC is readily available and cheap.
- Hardness: Rigid PVC ranks well for hardness and durability.
- Strength: Rigid PVC has excellent tensile strength.
Which metal is used to make PVC?
Chlorine is manufactured by the electrolysis of sodium chloride, salt. This is why the first PVC manufacturing plants were located close to natural sources of salt. The electrolysis of salt water produces chlorine….How is it produced.
| Additives | Properties achieved |
|---|---|
| Impact modifiers | To absorb shock without damage |
Why is PVC used for pipes?
PVC pipes are a safe choice for transportation of drinking water. This is due to their high degree of inertness and resistance to corrosion. PVC pipes are therefore free from bio-film contamination that can be a breeding ground for bacteria. By helping provide clean water, PVC pipes are beneficial to public health.
What is PVC?
Overview. Premature ventricular contractions (PVCs) are extra heartbeats that begin in one of the heart’s two lower pumping chambers (ventricles). These extra beats disrupt the regular heart rhythm, sometimes causing a sensation of a fluttering or a skipped beat in the chest.
What is PVC material made of?
PVC is made by reacting chlorine, carbon, and ethylene (a petrol product). The raw materials are essentially, salt and oil. Electrolysis of saltwater produces the chlorine, which is combined with ethylene (obtained from oil) to form vinyl chloride monomer (VCM).
Which material is made by PVC pipes?
Polyvinyl Chloride or PVC is a thermoplastic material derived from common salt and fossil fuels. The pipe material has the longest track record of all plastic materials. The first PVC pipes were made in the 1930’s.
Is PVC strong?
Strong, stiff, versatile low cost plastic material that is easy to fabricate, bond, and weld. Rigid PVC (polyvinyl chloride) is a strong, stiff, low cost plastic material that is easy to fabricate and easy to bond using adhesives or solvents. PVC is also easy to weld using thermoplastic welding equipment.
Does PVC melt in the sun?
PVC does surprisingly well when exposed to ultra violet rays (sunlight). Research shows little to no effect on PVC’s tensile strength or elasticity after prolonged sun exposure. The only degradation that seems to occur is impact strength.
Can you paint PVC?
PVC can be painted but it has to be prepared correctly and it needs to be painted with paints that are formulated for PVC.
Does PVC get brittle with age?
PVC pipes can become brittle and fail with age. But, PVC is an excellent option for the plumbing in your home.
Does PVC melt easily?
PVC is a thermoset material. It will become liquified at its melting point which ranges between 212F to 500F, depending on any additives used.
