Polyvinyl chloride (PVC) is a synthetic plastic polymer thermoplastic used in a broad range of applications. It appears in both rigid and flexible forms, and each form includes a number of different classifications. Additionally, while PVC is naturally brittle, manufacturers can add plasticizers to produce flexible materials. PVC plastic is the third most produced synthetic plastic polymer, with ~40 million tons produced every year.
Emco Industrial Plastics is the largest stocking distributor and fabricator of PVC sheet, rod and tube. Emco has served the chemical processing industry for over 40 years.
PVC Properties
Type 1 PVC – The normal impact grade material conforms to ASTM D 1784-81 Class 12454 B, Type 1, Grade 1. It features excellent chemical resistance in both acid and alkali solutions for temperatures up to a maximum of 140° F. All grades are self-extinguishing. Applications range from machined and fabricated parts to chemical processing and ventilation equipment.
Type 2 PVC – High impact grade material conforms to ASTM D-1784-81, Class 15344-D, Type II. Grade 1. Has excellent resistance to acids and alkaline solutions. Superior properties allow for cold rolling, vacuum-forming and ease of fabrication. Applications are primarily ventilation equipment, such as fume scrubbers, ducting and blower housings which require higher impact resistance than Type I provides.
Some properties of PVC plastic include:
High levels of hardness and density
Can incorporate heat stabilizers during processing to bolster heat resistance
PVC thermoplastic insulates materials, reducing the formation of condensation and resisting internal temperature changes of hot or cold liquids
Its polar nature renders it suitable for low- to medium-voltage and low-frequency insulation applications
PVC is chemically resistant to salts, acids, bases, alcohols, and fats, and as such, it can withstand corrosive sewage environments
Benefits of PVC Material
Many applications across a wide array of industries prize PVC plastic for its safety, flexibility, and durability. Key benefits include:
Good chemical stability allows PVC products to accept or convey different liquids without changing their material properties or composition
PVC material comes in rigid and flexible forms, as well as varying thicknesses and color options
Excellent corrosion resistance and can stand up to tough weather conditions
Excellent longevity—PVC materials in buildings can last over 20 years, and PVC water pipes remain operational for more than 50 years
High strength-to-weight ratio
PVC’s simple composition of readily available and affordable materials ensure it remains cost effective even in large quantities
Recyclers can easily grind PVC material into small pieces and melt it to make new PVC plastic products
PVC Plastic Applications
The diverse properties and benefits of PVC make it a common material choice for applications across many industries.
Building and construction: Due to its durability and weather resistance, the building and construction industry uses both rigid and flexible PVC plastic. PVC materials can replace traditional wood, metal, and concrete building materials. Construction firms use rigid PVC for roofing, siding, decking, fencing, wall coverings, and more. Flexible PVC can be found in piping, electrical cable insulation, caulks, sealants, and other materials.
Chemical Processing Industry: Emco can supply fabricated components for corrosion resistant exhaust systems in PVC Type I, as well as other thermoplastics, such as PVC Type II and CPVC. All are constructed to your specifications, and will meet all applicable standards. Other applications include: industrial waste treatment, brines, plant water distribution, roof drain systems, oil refining and the photographic industry.
Packaging: PVC’s light, flexible, transparent, strong, safe, and cost-effective qualities make it useful in packaging. PVC’s chemical stability allows its use in food packaging such as presentation trays and cling film without affecting taste. PVC blister packaging also appears in batteries, electronic components, and pharmaceutical tablets. Rigid PVC also packages disposable medical devices as it allows for radiation sterilization.
Healthcare: The healthcare industry has used PVC materials for over 50 years as an alternative to rubber and glass tubing and containers. Its rigid chemical composition prevents hazardous microbe invasion, and it is easy to clean. PVC plastics insulate against infection transmission when it is used in and between lab equipment.
Household products: PVC fabric helps shoes, coats, and aprons resist water seepage, and it’s a key component of artificial leather materials. Signs, stickers, ski equipment, and sports bags also include elements fabricated from PVC materials.
