PVC has the full chemical name of Polyvinyl Chloride, abbreviated as Vinyl. PVC compound is a raw material used to create many products used in everyday life, from common household items to unique industrial products.
Structure of PVC compounds
As a thermoplastic, PVC is made of 57% chlorine (derived from industrial salts) and 43% carbon (primarily derived from oil/gas via ethylene). This chlorine gives PVC excellent fire resistance. PVC has high stiffness and mechanical properties. The mechanical properties of rigid PVC (uPVC) are excellent; elastic modulus can reach 1500 - 3,000 MPa. Soft PVC (flexible PVC) elastic is 1.5 - 15 MPa. PVC has excellent insulating properties, making it ideal for wiring applications. Good impact strength and weatherproof properties make it suitable for construction products.
PVC compounds are durable, cheap, and easy to use. Before PVC can be manufactured into finished products, it always requires conversion into a mixture by incorporating additives (but not necessarily all). They are heat stabilizers, UV stabilizers, plasticizers, processing aids, impact modifiers, fillers, flame retardants, biocides, blowing agents, optionally, and colorants. The selection of additives used for finished PVC products is controlled by the cost performance requirements of the end-use specification. Various processes are used to form PVC Compounds, including extrusion, injection molding, blow molding, calendering, spreading, and coating.
Applications of PVC compounds
PVC is used to manufacture a wide variety of products because of its wide range of properties. PVC compounds are often mixed with other substances to determine if they will be rigid, flexible, or semi-rigid, and this, in turn, determines the type of product that will be made with PVC.
Some applications: Producing shoes; Power cables; Gaskets Application; Pipe Fittings; Polyvinyl Flooring; Garden Faucet; Plumbing parts; Medical devices; Automotive Parts; Waterproof devices; Toy; Food packaging.
While using PVC compound for applications, the only thing to watch out for is overheating. PVC can withstand a certain amount of heat, but not extreme heat and flames unless manufactured to be fire-resistant. When continuously exposed to high temperatures, PVC products may melt, and the product may release certain chemicals that can be harmful.
Business customers need to define their product requirements when working with PVC suppliers. The PVC compound manufacturer ensures that the plastic filler compounds are flame retardant, minimizing risk during use.
Is PVC compound recyclable?
The world is moving towards sustainability, reducing carbon emissions, minimizing environmental pollution. The typical act of global concern is plastic recycling.
Plastic is considered a part of the world, is everywhere, and can be recycled. Manufacturers of plastic products and PVC compounds can rest assured because there are unique PVC compounds with a lifespan of 140 years and can be recycled about seven times. Depending on the type of product and the grade of the material, their recyclability is different.
Most importantly, as a manufacturing business, it is important to be aware of plastic product responsibilities to choose quality materials and commit to recycling.
