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. Examples of flexible PVC products requiring transparency are wrap films, transparent bags and coating films. Applications include: Identifying the Tg of polymers is often used for quality control and research and development. PVC is the only general purpose plastic that allows free, wide and seamless adjustment of the required physical properties of products such as flexibility, elasticity, and impact resistance, by adding plasticisers, additives, and modifiers. PVC is manufactured with plasticizers, which confer rubbery properties on the end product. 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 PVC: RPVC (1.3–1.45 g cm-3) is denser than FPVC (1.1–1.35 g cm-3). Visit the IDES database for detailed specifications. We only use the. In general results for rigid PVC range from 10 to 25 (which usually meets the needed requirements) while flexible PVC materials can have higher radiant panel index results, typically ranging up to 50. Polyvinyl chloride (PVC) is one of the earliest industrialized plastic. PVC's inherent flame retardant and excellent electrical insulation properties make it ideal for cabling applications. PVC is also self-extinguishing per UL flammability tests. Polyvinyl Chloride or also known as PVC comes in two basic forms. Flexible PVC film starts to soften at 60C/140F. Does flexible PVC film have good electrical properties? Plasticized (Flexible) Polyvinyl Chloride (PVC-P) PVC-P is a thermoplastic, further classified as a polyvinyl plastic. These materials have many of the same properties as vulcanized rubber, but can be molded and extruded using conventional thermoplastic process equipment. POLYVINYL CHLORIDE (PVC) PROPERTIES PVC is the most widely used member of the vinyl family. This is due to its plasticizer content. This solid form can then be modified with the addition of fillers and plasticisers depending on the task at hand. Low Temperature Usage: -40 degrees C | 5 degrees C; High Temperature Usage: 60°C | 140°F; Tensile Strength. Mechanical. Color white, dark gray. In fact, vinyl films are widely used in refrigeration units. AuroraFlex™ SBS and SEBS compounds utilize multiple TPE/TPR chemistries to impart high-performance properties for durability and easy processing. So if your film will only be exposed to a heat environment below 60C/140F, flexible PVC film is a good choice. PVC is manufactured with plasticizers, which confer rubbery properties on the end product. By adjusting the type and amount of plasticizers, plastic molders can achieve a large range of flexible compositions. Value Test Method. We only use the material list to inform visitors that we are experienced in processing these materials for many fine products. Recently discovered health hazards due to extended exposure to the vinyl chloride monomer have resulted in strict production controls. 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. Material Notes: This property data is a summary of similar materials in the MatWeb database for the category "PVC, Extruded". PVC, or polyvinyl chloride, is a common thermoplastic and has uses in a variety of applications. It’s not as resistant to high temperatures, but it excels in low temperature applications. PVC's chemical structure of Chlorine polar groups and its amorphous nature allow it to mix easily with many different substances. Fire Properties of Polyvinyl Chloride | 5 Results from this test for some materials are shown in Table 7. To avoid improper resin selection, Contact PMC for additional help in determining the exact engineering resin required for your application. Hardness, Rockwell 110-120 ASTM D785. Flexibility can be increased over a wide range by adding varying amounts of several plasticizers such as dioctyl phthalate. Pipe, extruded wire covering, toys, bottles, door and window components, film and fabric coatings. Please Note: PMC does not sell the material listed below. The Seiden Crystal is an antistatic and fire retardant transparent PVC film for cleanrooms, flexible partitions and containment solutions. Flexible PVC is a soft, flexible material that ranges in appearance from transparent to opaque. It has a very low tensile strength and a moderately high ductility among thermoplastics. Hazen-Williams Factor C=150. The softer the film, the more plasticizer, the lower temp it melts at. HDPE: HDPE has a large value for strength-to-density ratio, and its density ranges from 0.93 g cm-3 to 0.97 g cm-3. 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. PVC offers excellent corrosion and weather resistance. Offered in a wide range from rubbery soft to semi-rigid, Flexible PVC is widely used for plastic profile extrusions because of … A frequent method of processing PVC involves the suspension of solid particles of the polymer in an appropriate plasticizer. This suspension, a "plastisol," is then heated resulting in a homogenous system which becomes a flexible solid upon cooling. ... Second is flexible forms that mostly used in cable insulation, ... Properties of PVC Plastic. 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). Depending on additives used in manufacturing with PVC, many qualities can be imbued in products including anti-mist, different colors, elasticity, fire retarding, flexibility, impact resistance and microbe prevention. By adjusting the type and amount of plasticizers, plastic molders can achieve a large range of flexible compositions. Polyvinyl chloride (PVC) products are 100% recyclable physically, chemically and energetically. Overview of materials for PVC, Extruded Categories: Polymer; Thermoplastic; Vinyl (PVC); PVC, Extruded. Flexible or plasticised PVC compounds, with a wide range of properties, can also be produced by the addition of plasticisers. A highly versatile polymer, PVC is compatible with many additives. PVC, Rigid Rigid PVC Resin Properties & Uses. Strength: Rigid PVC has extremely good tensile strength. Thermal Conductivity Its current output is outranked only by polyethylene, since it exhibits corrosion resistance and good insulation properties for many purposes. Please Note: PMC does not sell the material listed below. The films were conditioned according to ASTM D 882 and then tested following the ASTM methods indicated in Tables II–IV. It has a high strength-to-weight ratio and is a good electrical and thermal insulator. Standard physical properties including tensile strength, elongation, toughness, modulus, tear resistance, and barrier characteristics were evaluated for all films.
