Master Bond’s technical experts will review your application and recommend a product with the properties you need to meet your specific requirements. A frequent method of processing PVC involves the suspension of solid particles of the polymer in an appropriate plasticizer. The production of PVC film takes place in factories in Japan and USA, with strict quality control guidelines. PVC has inherently superior fire retarding properties due to its chlorine content, even in... Durability. The mechanical properties of rigid PVC (uPVC) are very good; the elastic modulus can reach 1500–3,000 MPa. LDPE retains good flexibility even at sheet thickness values of up to 40 millimeters. PVC is resistant to acids and bases. For example, a measurement taken by the Japan PVC Pipe and Fittings Association showed no deterioration in 35-year-old underground pipes. It is most commonly used in pipe and fittings. Posted on March 29, 2018. The transparency of plastic products is measured through the haze value. Tensile Strength: 2.60 N/mm2; Elongation: 100-400%; Notched Impact Strength: 2.0-45 Kj/m2; Thermal Coefficient of expansion: 80 x 10-6; Density 1.38 g/cm3 Specific Gravity (g/cu,cm) 1.40 ± .02 ASTM D792. PVC is strong, lightweight, durable and versatile. 3D Insider is ad supported and earns money from clicks and other ways. Visit the IDES database for detailed specifications. The Properties of Flexible TPU Filament, How to Work with it, and Best Brands. Flexible PVC film starts to soften at 60C/140F. PVC's physical properties Fire retarding properties. Properties of PVC. 29 Shares. Other types of PVC are called CPVC (PVC-C) (chlorinated PVC), which has a higher chlorine content and oriented PVC (PVC-O) which is PVC-U where the molecules are preferentially aligned in a particular direction. Usage of PVC has grown steadily since its introduction in the early 1930s to become a very widely used plastic in a myriad of uses from films and mouldings to extruded pipe. This durability applies even through the recycling process, because the physical properties of re-converted products are virtually the same as those made from virgin PVC … It is also possible to manufacture PVC products with superior gloss. It all starts with the composition of the product where only top-quality UV stabilisers and plasticisers are used. @ 73°F .75 ASTM D256, Expansion (in/in/°F) 2.9 x 10^-5 ASTM D696, (BTU/in/hr/ft/°F) 3.5 ASTM C177, °F @ 264 psi 170 ASTM D648, Specific Heat, Cal/°C/gm .25 ASTM D2766, Dielectric Strength, V/mil 1,413 ASTM D149, Dielectric Constant, 60 Hz, 30°F 3.7 ASTM D150, @ 95°C, ohms/cm 1.2 x 10^12 ASTM D257, Flammability Rating V-0 UL 94, Flame Spread Index <10 ASTM E162, Flame Spread 0-25 10-25 ULC ASTM E84, Flash Ignition Temp 730°F, Average Time of Burning (sec.) Flexural Strength, psi @ 73°F 14,450 ASTM D790. The soft PVC (flexible PVC) elastic modulus is 1.5-15. Before PVC can be made into products, it has to be combined with a range of special additives. These materials have many of the same properties as vulcanized rubber, but can be molded and extruded using conventional thermoplastic process equipment. 250°F, Material Becomes Viscous 350°F, Material Carbonizes 425°F, Smoke Generation 80-225 600-1000 ULC ASTM E84, Please Use Chat Feature Below to Contact Us - 8-4pm EST M-F. It’s not as resistant to high temperatures, but it excels in low temperature applications. properties enhance with the molecular weight increases, but decreases with the temperature increasing. The soft PVC (flexible PVC) elastic limit is 1.5–15 MPa. Flexibility can be increased over a wide range by adding varying amounts of several plasticizers such as dioctyl phthalate.
