Tansparent PVC Oxygen Mask Raw Material PVC Powder PVC Plastic Granule
What is PVC (PolyVinyl Chloride)?
Polyvinyl Chloride (PVC or Vinyl) is an economical and versatile thermoplastic polymer. It is widely used in the building and construction industry to produce door and window profiles. It also finds use in:
drinking and wastewater pipes,
wire and cable insulation,
medical devices, etc.
It is the world’s third-largest thermoplastic by volume after polyethylene and polypropylene.
It is a white, brittle solid material available in powder form or granules. PVC is now replacing traditional building materials in several applications. These materials include wood, metal, concrete, rubber, ceramics, etc. in several applications. This is due to its versatile properties such as:
lightweight,
durable,
low cost, and
easy processability.
