In fact, vinyl films are widely used in refrigeration units. Vinyl (PVC) tubing is very popular because it is flexible, versatile, and economical. See also polyvinyl chloride/vinylidene chloride. PVC has excellent resistance to water and aqueous solutions, but it is attacked severely by stronger solvents such as aromatic hydrocarbons, ketones, esters and chlorinated solvents. This value is a percentage calculated by dividing the diffused light transmittance of the test piece with the total light transmittance. 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. 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. PVC is an amorphous polymer and as a result its products can be made to be transparent. It has a high strength-to-weight ratio and is a good electrical and thermal insulator. Pipe, extruded wire covering, toys, bottles, door and window components, film and fabric coatings. <5 ASTM D635, Softening Starts, (approx.) 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. 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 has a very low tensile strength and a moderately high ductility among thermoplastics. 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's physical properties Fire retarding properties. Flexible vinyl film has good barrier properties to oil and grease but is oxygen permeable. The soft PVC (flexible PVC) elastic limit is 1.5–15 MPa. There are, therefore, many different PVC products available with varying additive compositions and properties. Several alloys and copolymers are possible with PVC, including styrene and acrylonitrile. Properties of PVC. Approximately 90% of all plasticizers are used in polyvinyl chloride, or PVC. Flexural Strength, psi @ 73°F 14,450 ASTM D790. They are soft and flexible in nature; their Tgs are less than room temperature. It all starts with the composition of the product where only top-quality UV stabilisers and plasticisers are used. Modulus of Elasticity, psi @ 73°F (Tensile Modulus) 420,000 ASTM D638. PVC Pipe. It also has good cling, excellent clarity and puncture resistant. 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. It has high hardness and mechanical strength, meaning it is very strong. This solid form can then be modified with the addition of fillers and plasticisers depending on the task at hand. Key mechanical properties include tensile, flex, compression and impact. Applications include: Identifying the Tg of polymers is often used for quality control and research and development. It is most commonly used in pipe and fittings. For example, a measurement taken by the Japan PVC Pipe and Fittings Association showed no deterioration in 35-year-old underground pipes. So if your film will only be exposed to a heat environment below 60C/140F, flexible PVC film is a good choice. Under normal conditions of use, the most influential factor in affecting the durability of a material is its... Oil/chemical resistance. As a material, PVC has not changed much since 1926. 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. 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. MECHANICAL. PVC is resistant to acids and bases. It’s not as resistant to high temperatures, but it excels in low temperature applications. 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. 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 … The chlorine is manufactured by the electrolysis of sodium chloride (salt) and the carbon originates from oil. FlexPVC Flexible PVC Pipe fits standard Sch 40 and Sch 80 fittings.

Value Test Method. 29 Shares. Recently discovered health hazards due to extended exposure to the vinyl chloride monomer have resulted in strict production controls. by Joseph Flynt. Also, it is an important tool used to modify physical properties of polymer molecules. Flexibility can be increased over a wide range by adding varying amounts of several plasticizers … 3D Insider is ad supported and earns money from clicks and other ways. These materials have many of the same properties as vulcanized rubber, but can be molded and extruded using conventional thermoplastic process equipment. Flexible PVC is a vinyl polymer. Wendt has been the supplier of transparent PVC film in Europe for more than 25 years. These characteristics make it ideal for window profiles. Figure 2.Compari… Flexibility can be increased over a wide range by adding varying amounts of several plasticizers such as dioctyl phthalate. The production of PVC film takes place in factories in Japan and USA, with strict quality control guidelines. Our FlexPVC brand Flexible PVC pipe has an NSF 50 rating. The mechanical properties of rigid PVC (uPVC) are very good; the elastic modulus can reach 1500–3,000 MPa. Posted on March 29, 2018. For most 3D printing needs, the standard PLA and ABS filaments are reliable enough in terms of product quality and workability. 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). DEHP is used in PVC for applications like blood bags, intravenous bags, flexible tubing, catheters, and protective gloves. 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. Visit the IDES database for detailed specifications. POLYVINYL CHLORIDE (PVC) PROPERTIES PVC is the most widely used member of the vinyl family. LDPE retains good flexibility even at sheet thickness values of up to 40 millimeters. This is due to its plasticizer content. It is also possible to manufacture PVC products with superior gloss. Unmodified polyvinylchloride is a very rigid thermoplastic. These properties make flexible PVC suitable for food packaging to keep 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 Flexible PVC film starts to soften at 60C/140F. PVC is one of the most durable materials in the world because of plasticizers added to it, lasting up to 50 years without damage. PVC, or polyvinyl chloride, is a common thermoplastic and has uses in a variety of applications. Flexible or plasticised PVC compounds, with a wide range of properties, can also be produced by the addition of plasticisers. Flexible PVC (Polyvinyl Chloride) Unmodified polyvinylchloride is a very rigid thermoplastic. Cheap, resistant, good weatherabiligy, ect. properties enhance with the molecular weight increases, but decreases with the temperature increasing. The mechanical properties enhance with the molecular weight increasing but decrease with the temperature increasing. This suspension, a "plastisol," is then heated resulting in a homogenous system which becomes a flexible solid upon cooling. Knowledge of its properties is important in understanding if PVC has the strength for use in a specific application. Thermoplastic PVC is made of 57% chlorine and 43% carbon. The soft PVC (flexible PVC) elastic modulus is 1.5-15. PVC is also self-extinguishing per UL flammability tests. Common Names: PVC (polyvinyl chloride) Temperature Range. Flexible PVC AuroraFlex™ SBS and SEBS compounds utilize multiple TPE/TPR chemistries to impart high-performance properties for durability and easy processing.
