properties of flexible pvc

PVC is also self-extinguishing per UL flammability tests. A frequent method of processing PVC involves the suspension of solid particles of the polymer in an appropriate plasticizer. It’s not as resistant to high temperatures, but it excels in low temperature applications. Posted on March 29, 2018. @ 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.) Before PVC can be made into products, it has to be combined with a range of special additives. Pipe, extruded wire covering, toys, bottles, door and window components, film and fabric coatings. Cheap, resistant, good weatherabiligy, ect. For most 3D printing needs, the standard PLA and ABS filaments are reliable enough in terms of product quality and workability. The mechanical properties of rigid PVC (uPVC) are very good; the elastic modulus can reach 1500–3,000 MPa. PVC Properties. Flexible PVC film starts to soften at 60C/140F. Modulus of Elasticity, psi @ 73°F (Tensile Modulus) 420,000 ASTM D638. The mechanical properties of rigid PVC (UPVC) are very good, the elastic modulus can get to 1500-3,000. Due to DEHP's unique properties, cost-effectiveness, and versatility, it can be used to tailor the properties of the products from soft and flexible to strong and tough. It has a very low tensile strength and a moderately high ductility among thermoplastics. Plasticized (Flexible) Polyvinyl Chloride (PVC-P) PVC-P is a thermoplastic, further classified as a polyvinyl plastic. The transparency of plastic products is measured through the haze value. Flexible PVC AuroraFlex™ SBS and SEBS compounds utilize multiple TPE/TPR chemistries to impart high-performance properties for durability and easy processing. PVC Pipe. The softer the film, the more plasticizer, the lower temp it melts at. Master Bond’s technical experts will review your application and recommend a product with the properties you need to meet your specific requirements. The Properties of Flexible TPU Filament, How to Work with it, and Best Brands. It has a low temperature tolerance, breaking down at temperatures over 140 degrees Fahrenheit and melting at temperatures over 160 degrees, unless it is put through an extra chlorination process; this makes it CPVC. Cell Classification 12454 ASTM D1784, Color white, dark gray, 24hrs @ 25°C .05 ASTM D570, Hardness, Rockwell 110-120 ASTM D785, Specific Gravity (g/cu,cm) 1.40 ± .02 ASTM D792, Tensile Strength, psi @ 73°F 7,450 ASTM D638, psi @ 73°F (Tensile Modulus) 420,000 ASTM D638, Flexural Strength, psi @ 73°F 14,450 ASTM D790, Compressive Strength, psi @ 73°F 9,600 ASTM D695, Izod Impact, ft-lb./in. These additives can influence or determine a number of the products properties, namely; its mechanical properties, weather fastness, its colour and clarity and indeed whether it is to be used in a flexible application. These compounds exhibit the advanced properties required for a number of different industries, including the aerospace, medical, optical, electrical, electronic and other manufacturing industries. 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. 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. <5 ASTM D635, Softening Starts, (approx.) It is also possible to manufacture PVC products with superior gloss. Specific Gravity (g/cu,cm) 1.40 ± .02 ASTM D792. Key mechanical properties include tensile, flex, compression and impact. 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 … PVC is an amorphous polymer and as a result its products can be made to be transparent. By volume, after Polyethylene (PE) and Polypropylene (PP), PVC is the third largest polymer used in products. Vinyl (PVC) tubing is very popular because it is flexible, versatile, and economical. Common Names: PVC (polyvinyl chloride) Temperature Range. 29 Shares. properties enhance with the molecular weight increases, but decreases with the temperature increasing. pvc Vinyl film also known as polyvinyl chloride, or PVC is a versatile, cheap thermoplastic of good dimensional stability, good impact strength, and excellent weathering properties that can be easily die-cut and that is printable with conventional screen and offset printing methods. Rigid PVC is used in a broad range of applications, including: Building & Construction; Exterior Siding There are, therefore, many different PVC products available with varying additive compositions and properties. These properties make flexible PVC suitable for food packaging to keep 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. PVC is resistant to acids and bases. Low Temperature Usage: -40 degrees C | 5 degrees C; High Temperature Usage: 60°C | 140°F; Tensile Strength. Value Test Method. It all starts with the composition of the product where only top-quality UV stabilisers and plasticisers are used. It has a high strength-to-weight ratio and is a good electrical and thermal insulator. Due to PVC properties, as described above, around 50% of PVC (or vinyl) manufactured is used in construction replacing other materials such as wood or glass. PVC's physical properties Fire retarding properties. Applications include: Identifying the Tg of polymers is often used for quality control and research and development. It also has good cling, excellent clarity and puncture resistant. As a material, PVC has not changed much since 1926. Our FlexPVC brand Flexible PVC pipe has an NSF 50 rating. This solid form can then be modified with the addition of fillers and plasticisers depending on the task at hand. See also polyvinyl chloride/vinylidene chloride. This suspension, a "plastisol," is then heated resulting in a homogenous system which becomes a flexible solid upon cooling. Physical Properties of. Figure 2.Compari… It is most commonly used in pipe and fittings. The production of PVC film takes place in factories in Japan and USA, with strict quality control guidelines. The chlorine is manufactured by the electrolysis of sodium chloride (salt) and the carbon originates from oil. PVC has high hardness and mechanical properties. For example, a measurement taken by the Japan PVC Pipe and Fittings Association showed no deterioration in 35-year-old underground pipes. LDPE retains good flexibility even at sheet thickness values of up to 40 millimeters.
