The soft PVC (flexible PVC) elastic limit is 1.5–15 MPa. Cheap, resistant, good weatherabiligy, ect. PVC has high hardness and mechanical properties. They are soft and flexible in nature; their Tgs are less than room temperature. Knowledge of its properties is important in understanding if PVC has the strength for use in a specific application. by Joseph Flynt. Posted on March 29, 2018. Flexible polyvinyl chloride (PVC) is one of the largest-volume medical film materials, and as such provides a significant opportunity for both raw material and waste reduction. 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 … Flexible or plasticised PVC compounds, with a wide range of properties, can also be produced by the addition of plasticisers. Tensile Strength, psi @ 73°F 7,450 ASTM D638. Flexible PVC is a vinyl polymer. Vinyl (PVC) tubing is very popular because it is flexible, versatile, and economical. A frequent method of processing PVC involves the suspension of solid particles of the polymer in an appropriate plasticizer. For example, a measurement taken by the Japan PVC Pipe and Fittings Association showed no deterioration in 35-year-old underground pipes. These materials have many of the same properties as vulcanized rubber, but can be molded and extruded using conventional thermoplastic process equipment. PVC offers excellent corrosion and weather resistance. Pipe, extruded wire covering, toys, bottles, door and window components, film and fabric coatings. 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, or polyvinyl chloride, is a common thermoplastic and has uses in a variety of applications. Figure 2.Compari… 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. Yes. Flexible PVC AuroraFlex™ SBS and SEBS compounds utilize multiple TPE/TPR chemistries to impart high-performance properties for durability and easy processing. PVC has inherently superior fire retarding properties due to its chlorine content, even in... Durability. 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. Also, it is an important tool used to modify physical properties of polymer molecules. 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. The mechanical properties of rigid PVC (UPVC) are very good, the elastic modulus can get to 1500-3,000. properties enhance with the molecular weight increases, but decreases with the temperature increasing. PVC is resistant to acids and bases. The mechanical properties of rigid PVC (uPVC) are very good; the elastic modulus can reach 1500–3,000 MPa. @ 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.) PVC, Rigid: Chemical Name: Polyvinyl Chloride, Rigid: Structure: Amorphous: Opacity: Clear to Opaque: Strength: Tough: Specific Gravity: 1.45: Shrinkage: 0.4% to 1.0%: Melting Point: 185° F Deflection Temperature: 150.8° F – 192.2° F: Service Temperature: 140° F: Applications. So if your film will only be exposed to a heat environment below 60C/140F, flexible PVC film is a good choice. For most 3D printing needs, the standard PLA and ABS filaments are reliable enough in terms of product quality and workability. The soft PVC (flexible PVC) elastic modulus is 1.5-15. Under normal conditions of use, the most influential factor in affecting the durability of a material is its... Oil/chemical resistance. MECHANICAL. Key mechanical properties include tensile, flex, compression and impact. Plasticized or Flexible PVC (Density: 1.1-1.35 g/cm3): Flexible PVC is formed by the addition of compatible plasticizers to PVC which lower the crystallinity. Flexural Strength, psi @ 73°F 14,450 ASTM D790. Applications include: Identifying the Tg of polymers is often used for quality control and research and development. This solid form can then be modified with the addition of fillers and plasticisers depending on the task at hand. It is most commonly used in pipe and fittings. In fact, vinyl films are widely used in refrigeration units. Common Names: PVC (polyvinyl chloride) Temperature Range. 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. 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. Figure 1.Polyvinyl Chloride structure PVC is a white, brittle solid available in powder form or granules, formed through an addition polymerisationreaction between vinyl chloride monomers (Figure 1). Physical Properties of. The chlorine is manufactured by the electrolysis of sodium chloride (salt) and the carbon originates from oil. POLYVINYL CHLORIDE (PVC) PROPERTIES PVC is the most widely used member of the vinyl family. It is suitable for direct burial, and approved applications include swimming pools, hot tubs, spas, irrigation and for other purposes. Modulus of Elasticity, psi @ 73°F (Tensile Modulus) 420,000 ASTM D638. These compounds exhibit the advanced properties required for a number of different industries, including the aerospace, medical, optical, electrical, electronic and other manufacturing industries. PVC Pipe. Flexibility can be increased over a wide range by adding varying amounts of several plasticizers … PVC is one of the most durable materials in the world because of plasticizers added to it, lasting up to 50 years without damage. The transparency of plastic products is measured through the haze value. Properties of PVC. 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. 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. PVC's physical properties Fire retarding properties. PVC is strong, lightweight, durable and versatile. <5 ASTM D635, Softening Starts, (approx.) Recently discovered health hazards due to extended exposure to the vinyl chloride monomer have resulted in strict production controls. The softer the film, the more plasticizer, the lower temp it melts at. FlexPVC Flexible PVC Pipe fits standard Sch 40 and Sch 80 fittings. It has a high strength-to-weight ratio and is a good electrical and thermal insulator. Visit the IDES database for detailed specifications.
