BUY POLYVINYL CHLORIDE
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.
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.
What are the basic forms of PVC?
Polyvinyl Chloride is widely available in two broad categories: Flexible and Rigid. But there are more types like CPVC, PVC-O and PVC-M.
- Plasticized or Flexible PVC (Density: 1.1-1.35 g/cm3): Flexible PVCis formed by the addition of compatible plasticizers to PVC which lower the crystallinity. These plasticizers act like lubricants resulting in a much clearer and flexible plastic. This type of PVC is sometimes called as PVC-P.
- Unplasticized or Rigid PVC (Density: 1.3-1.45 g/cm3): Rigid PVCis a stiff and cost-effective plastic. It shows high resistance to impact, water, weather, chemicals and corrosive environments. This type of PVC is also known as UPVC, PVC-U or uPVC.
- Chlorinated Polyvinyl Chloride or perchlorovinyl: It is prepared by chlorination of PVC resin. High chlorine content imparts high durability, chemical stability and flame retardancy. CPVCcan withstand a wider range of temperatures.
- Molecular Oriented PVC or PVC-O: It is formed by reorganizing the amorphous structure of PVC-U into a layered structured. Bi-axially oriented PVC has enhanced physical characteristics (stiffness, fatigue resistance, lightweight, etc.).
- Modified PVC or PVC-M: It is an alloy of PVC formed by addition of modifying agents, resulting in enhanced toughness and impact properties.
What are the key properties of PVC?
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. It is the preferred choice for many long-life and outdoor products.
Flame Retardancy: Because of its high chlorine content, PVC products are self-extinguishing. Its oxidation index is ≥45. Antimony trioxide has been extensively used in combination with phosphate ester plasticizers. This gives excellent fire performance and mechanical properties.
Cost/Performance Ratio: PVC has good physical as well as mechanical properties. It also provides excellent cost-performance advantages. It has a long life span and needs low maintenance.
Mechanical Properties: PVC is abrasion-resistant, lightweight, and tough.
Chemical Resistance: PVC is resistant to all inorganic chemicals. It has very good resistance against diluted acids, diluted alkalis, and aliphatic hydrocarbons. Some grades are attacked by:
ketones and esters,
chlorinated and aromatic hydrocarbons,
aromatic ethers and amines, and
nitro-compounds
Is PVC recyclable?
Products made from PVC are 100% recyclable. They can be identified as recycling code #3.
Adopting an appropriate recycling pathway for PVC is of economic value and has an environmental benefit. Key methods for PVC recycling include:
Mechanical Recycling
In mechanical recycling, the PVC waste is treated through shredding, sieving, and grinding. Depending on the composition, the quality of the recyclates can vary a lot. To discard impurities within these recyclates they are further:
- mechanically separated,
- ground,
- washed, and
- treated
It is reprocessed using various granulated or powder techniques and reused in production. “High-quality” recyclates can be re-used in the same types of applications. “Low-quality” recyclates can only be used in products made from other materials.
Chemical Recycling
Chemical recycling breaks up polymer into monomers and other substances.
- Monomers– Used to produce new polymers.
- Other substances– Used as starting materials in processes of the basic chemical industry.
The Chlorine is set free in the form of HCl that can be re-used or neutralized to form various products. Stabilizers containing heavy metals mostly end up in solid residues that will most probably have to be landfilled.
Feedstock Recycling
It usually involves thermal treatment of the PVC waste stream with the recovery of hydrogen chloride. It can be then returned to the PVC production process or used in other processes.
Recycled PVC can be used to produce packaging, film and sheet, loose-leaf binders, pipes, carpet backing, electrical boxes, cables and more. The industry is working with the regulatory authorities to ensure that recycling activities remain sustainable while complying with the regulatory regime.
