properties of flexible pvc

The mechanical properties enhance with the molecular weight increasing but decrease with the temperature increasing. These materials have many of the same properties as vulcanized rubber, but can be molded and extruded using conventional thermoplastic process equipment. It is also possible to manufacture PVC products with superior gloss. 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 offers excellent corrosion and weather resistance. Flexible PVC AuroraFlex™ SBS and SEBS compounds utilize multiple TPE/TPR chemistries to impart high-performance properties for durability and easy processing. The chlorine is manufactured by the electrolysis of sodium chloride (salt) and the carbon originates from oil. Specific Gravity (g/cu,cm) 1.40 ± .02 ASTM D792. Also, it is an important tool used to modify physical properties of polymer molecules. So if your film will only be exposed to a heat environment below 60C/140F, flexible PVC film is a good choice. For example, a measurement taken by the Japan PVC Pipe and Fittings Association showed no deterioration in 35-year-old underground pipes. This solid form can then be modified with the addition of fillers and plasticisers depending on the task at hand. POLYVINYL CHLORIDE (PVC) PROPERTIES PVC is the most widely used member of the vinyl family. PVC is strong, lightweight, durable and versatile. These properties make flexible PVC suitable for food packaging to keep 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. These characteristics make it ideal for window profiles. It has a high strength-to-weight ratio and is a good electrical and thermal insulator. This is due to its plasticizer content. Modulus of Elasticity, psi @ 73°F (Tensile Modulus) 420,000 ASTM D638. However, elongation at break is up to 200-450%. Flexible or plasticised PVC compounds, with a wide range of properties, can also be produced by the addition of plasticisers. Wendt has been the supplier of transparent PVC film in Europe for more than 25 years. It’s not as resistant to high temperatures, but it excels in low temperature applications. Master Bond’s technical experts will review your application and recommend a product with the properties you need to meet your specific requirements. Because PVC film provides a wide array of functional performance characteristics at a low cost, any potential replacement material will need to provide similar performance at a comparable total system cost. PVC has high hardness and mechanical properties. It also has good cling, excellent clarity and puncture resistant. PVC Pipe. TPO & Santoprene™- Emergency Relief Shelter Component, PVC & Flexible PVC - Co-extruded Reversable Wire conduit, Santoprene™ - Expansion Joint for construction, United Plastics Components Launches Video, Wide range of flexibility possible with varying levels of plasticizer. This value is a percentage calculated by dividing the diffused light transmittance of the test piece with the total light transmittance. Flexible PVC is a vinyl polymer. PVC has inherently superior fire retarding properties due to its chlorine content, even in... Durability. Low-density polyethylene is the most common plastic used for flexible plastic sheets on account of the fact that it’s very flexible. By volume, after Polyethylene (PE) and Polypropylene (PP), PVC is the third largest polymer used in products. Flexibility can be increased over a wide range by adding varying amounts of several plasticizers such as dioctyl phthalate. Properties of PVC. See also polyvinyl chloride/vinylidene chloride. •Physical Properties of Flexible PVC using specially plasticizers •Requirements for PVC Plasticizers •General Relationships between the structure of Plasticizers and their behaviour in PVC •Characteristics of the Major Types of Plasticizer •Polymeric Modifiers for PVC The mechanical properties of rigid PVC (UPVC) are very good, the elastic modulus can get to 1500-3,000. Vinyl (PVC) tubing is very popular because it is flexible, versatile, and economical. 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 Knowledge of its properties is important in understanding if PVC has the strength for use in a specific application. 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. Common Names: PVC (polyvinyl chloride) Temperature Range. Thermoplastic PVC is made of 57% chlorine and 43% carbon. Our FlexPVC brand Flexible PVC pipe has an NSF 50 rating. by Joseph Flynt. This suspension, a "plastisol," is then heated resulting in a homogenous system which becomes a flexible solid upon cooling. <5 ASTM D635, Softening Starts, (approx.) A frequent method of processing PVC involves the suspension of solid particles of the polymer in an appropriate plasticizer. Yes. PVC is resistant to acids and bases. The production of PVC film takes place in factories in Japan and USA, with strict quality control guidelines. It has high hardness and mechanical strength, meaning it is very strong. Applications include: Identifying the Tg of polymers is often used for quality control and research and development. 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. It offers outstanding clarity and is used in a wide range of applications and settings, from general laboratory use to food, beverage, medical device, and pharmaceutical manufacturing. Visit the IDES database for detailed specifications. 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. Pipe, extruded wire covering, toys, bottles, door and window components, film and fabric coatings. LDPE retains good flexibility even at sheet thickness values of up to 40 millimeters. The transparency of plastic products is measured through the haze value. Several alloys and copolymers are possible with PVC, including styrene and acrylonitrile. Rigid PVC is used in a broad range of applications, including: Building & Construction; Exterior Siding Before PVC can be made into products, it has to be combined with a range of special additives. The soft PVC (flexible PVC) elastic modulus is 1.5-15. It is most commonly used in pipe and fittings. 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.
