Polyvinyl Chloride (PVC) is a fine, white, odorless powder, soluble in ketones and tetrahydrofuran. The product is obtained through the polymerization of vinyl chloride suspension. PVC's major benefit is its compatibility with many different kinds of additives, making it a highly versatile polymer. Its compatibility with additives allows for the possible addition of flame-retardants although PVC is intrinsically fire retardant because of the presence of chlorine in the polymer matrix. PVC has excellent electrical insulation properties, making it ideal for cabling applications, weatherproof and impact strength (ideal for electrical cables and construction materials). PVC Suspension can only be used in mixture with the appropriate additives able to render the polymer in a form which can be processed in a useful finished product. Depending on the plasticizer content, it results a semi-rigid finished product (low plasticizer content), flexible finished product (high plasticizer content). OLTVIL 1 64100 is a PVC grade indicated for use in plasticized, semi-rigid and rigid applications. OLTVIL 1 64100 is recommended for formulation of vinyl compounds used especially for processing by extrusion, injection, compresion or calendering.
