What is PVC?
Polyvinyl chloride (PVC), also known as polyvinyl or vinyl, commonly abbreviated PVC, is the world's third-most widely produced synthetic plastic polymer, after polyethylene and polypropylene.
PVC comes in two basic forms: rigid (sometimes abbreviated as RPVC) and flexible. The rigid form of PVC is used in construction for pipe and in profile applications such as doors and windows. It is also used in making bottles, non-food packaging, and cards (such as bank or membership cards). It can be made softer and more flexible by the addition of plasticizers, the most widely used being phthalates. In this form, it is also used in plumbing, electrical cable insulation, imitation leather, flooring, signage, phonograph records, inflatable products, and many applications where it replaces rubber.
Reflectivity & Sustainability
PVC plays a major role in delivering and sustaining the quality, comfort and safety of modern life-styles. Its impressive ratio of cost to performance also means that people of all income groups can enjoy these benefits. High living standards are not just about the present, however. Future generations also have the right to material and other benefits. This is the foundation of the concept of ‘Sustainable Development’.
PVC roofing membranes are sometimes referred to as vinyl are a combination of the chemicals ethylene and chlorine. During the production process, other materials are added to PVC to enhance certain features that serve its roofing purpose. These various additives include plasticizers, biocides, UV light inhibitors, color pigment, heat stabilizers and fiberglass or polyester reinforcements. With the addition of these chemicals, PVC roofing membranes become resistant to water damage, UV light degradation, high winds and fires.
