What are the properties of PVC?

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.

What is PVC what are its properties and uses?

It is a white, brittle solid material available in powder form or granules. Due to its versatile properties, such as lightweight, durable, low cost and easy processability, PVC is now replacing traditional building materials like wood, metal, concrete, rubber, ceramics, etc. in several applications.

What is the Young’s modulus of PVC?

Polyvinyl chloride hard

Young’s modulus 3275 MPa
Melting temperature Amorphou °C
Glass temperature 85 °C
Minimum service temperature -10 °C
Maximum service temperature 70 °C

What is the yield strength of PVC?

Physical Properties Metric English
Tensile Strength, Ultimate 14.3 – 53.7 MPa 2080 – 7790 psi
Tensile Strength, Yield 3.45 – 73.1 MPa 500 – 10600 psi
Elongation at Break 2.00 – 330 % 2.00 – 330 %
Elongation at Yield 3.10 – 6.00 % 3.10 – 6.00 %

What is the raw material of PVC?

The essential raw materials for PVC are derived from salt and oil. The electrolysis of salt water produces chlorine, which is combined with ethylene (obtained from oil) to form vinyl chloride monomer (VCM).

Can PVC be melted and molded?

PVC is a thermoset material. It will become liquified at its melting point which ranges between 212F to 500F, depending on any additives used. PVC can be melted for injection molding purposes, cooled and then heated again without degredation.

What are PVC atoms?

Structurally, PVC is a vinyl polymer. (well, duh!) It’s similar to polyethylene, but on every other carbon in the backbone chain, one of the hydrogen atoms is replaced with a chlorine atom. It’s produced by the free radical polymerization of vinyl chloride.

Why is PVC brittle?

PVC pipe can become brittle due to chemical exposure. As a polymer, chemicals can have a profound negative effect on the makeup of PVC, causing loosening of bonds between molecules in the plastic and hastening the rate of plasticizer migration out of the pipe.

What is PVC density?

– PVC is chemically stable and does not de-polymerize. – Density: 1.32-1.42 g/cc.

What is PVC material for furniture?

Poly-Vinyl Chloride or PVC material is sheets made of plastic composite. It is understandable that when one talks about Poly-Vinyl Chloride or PVC material, the first thing that flashes in mind is pipes, bathroom or plumbing material. But today, due to its durability and ease of availability, PVC has many other uses.

What melts PVC plastic?

Melting PVC plastic can be a very simple project depending on your reason for melting it. If you simply need to melt the PVC enough that it is pliable, a heat gun will get the job done. If you need to melt the PVC to the extent that you can mold and shape it, you will need a double boiler.

What is Unplasticised PVC?

Unplasticised Polyvinyl Chloride – Unplasticised PVC – UPVC. It is an amorphous commodity thermoplastic that can be colorless and transparent but is much more commonly pigmented. It is strong, stiff, and inherently flame retardant with relatively good chemical resistance (solvents are its weak area, particularly stress cracking therein).

Is UPVC a rigid plastic?

Unplasticized (Rigid) Polyvinyl Chloride (uPVC, PVC-U) UPVC is a thermoplastic, further classified as a polyvinyl plastic. It has a moderately low heat capacity among thermoplastics. In addition, it has a moderately high ductility and a moderately low tensile strength.

What is polyvinyl chloride (PVC)?

Polyvinyl chloride, commonly referred to as PVC or Vinyl, is the world’s 3 rd most synthesised thermoplastic material. Its most well-known application is the formation of PVC pipes in the building and construction industry, but the benefits of PVC extend far beyond this into the medical, electrical and protective clothing sectors.

What is the chemical resistance of PVC-U?

PVC-U has a tin stabilised compound conforming to all EEC safety standards for the material VCM (Vinyl Chloride Monomer) and the WRc requirements for potable water use. The chemical resistance properties of PVC-U are excellent. It is resistant to most solutions of acids, alkalis, salts and solutions which can be mixed with water.
