In fact, vinyl films are widely used in refrigeration units. GENERAL. Does flexible PVC film have good electrical properties? 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. They are also used in packaging (blisters). FLEXIBLE. Some of the most significant properties of Polyvinyl Chloride (PVC) are: Density: PVC is very dense compared to most plastics (specific gravity around 1.4) Economics: PVC is readily available and cheap. PVC has been used extensively in a wide range of construction products for over half a century. Flexibility can be increased over a wide range by adding varying amounts of several plasticizers such as dioctyl phthalate. It has a very low tensile strength and a moderately high ductility among thermoplastics. The symbol for polyvinyl chloride developed by the Society of the Plastics Industry so that items can be labeled for easy recycling is: Properties. Density. Hardness: Rigid PVC is very hard. Figure 2.Compari… PVC comes in two forms (rigid PVC – RPVC and flexible PVC – FPVC), and some of their properties slightly vary. PVC's strong, lightweight, durable and versatile characteristics make it ideal for window profiles. Offered in a wide range from rubbery soft to semi-rigid, Flexible PVC is widely used for plastic profile extrusions because of … This solid form can then be modified with the addition of fillers and plasticisers depending on the task at hand.

Its properties are usually categorized based on rigid and flexible PVCs. Material Notes: This property data is a summary of similar materials in the MatWeb database for the category "PVC, Extruded". These materials have many of the same properties as vulcanized rubber, but can be molded and extruded using conventional thermoplastic process equipment. Pipe, extruded wire covering, toys, bottles, door and window components, film and fabric coatings. 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. Flexible PVC is a soft, flexible material that ranges in appearance from transparent to opaque. Examples of flexible PVC products requiring transparency are wrap films, transparent bags and coating films. We only use the. A frequent method of processing PVC involves the suspension of solid particles of the polymer in an appropriate plasticizer. We only use the material list to inform visitors that we are experienced in processing these materials for many fine products. 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. Key mechanical properties include tensile, flex, compression and impact. Flexible PVC film starts to soften at 60C/140F. Cell Classification 12454 ASTM D1784. Rigid PVC has an oxygen index of 45-50, compared to 21-22 for wood and 17-18 for most thermoplastics. Recently discovered health hazards due to extended exposure to the vinyl chloride monomer have resulted in strict production controls. Value Test Method. PVC is manufactured with plasticizers, which confer rubbery properties on the end product. Flexible PVC (Polyvinyl Chloride) Unmodified polyvinylchloride is a very rigid thermoplastic. POLYVINYL CHLORIDE (PVC) PROPERTIES PVC is the most widely used member of the vinyl family. Flexibility can be increased over a wide range by adding varying amounts of several plasticizers such as dioctyl phthalate. 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. 1. Mechanical. PVC Properties. See also polyvinyl chloride/vinylidene chloride. Rigid PVC products that have high transparency are used in construction materials such as day-lighting, transparent partitions for clean rooms, or industrial flat plates, corrugated panels. It has a high strength-to-weight ratio and is a good electrical and thermal insulator. PVC is widely used in a number of industries and fields, including construction, furniture, automobile and medical applications. The Seiden Crystal is an antistatic and fire retardant transparent PVC film for cleanrooms, flexible partitions and containment solutions. AuroraFlex™ SBS and SEBS compounds utilize multiple TPE/TPR chemistries to impart high-performance properties for durability and easy processing. However, plasticized PVC has a lower melting point, is less resistant to chemicals, and has a lower ultimate tensile strength than rigid vinyl. They are soft and flexible in nature; their Tgs are less than room temperature. Color white, dark gray. 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. What is the heat resistance of flexible PVC film and sheets? Hazen-Williams Factor C=150. So if your film will only be exposed to a heat environment below 60C/140F, flexible PVC film is a good choice. This is due to its plasticizer content. Visit the IDES database for detailed specifications. Oxygen index values above 27 can easily be attained with flexible PVC. Flexible PVC offers a number of advantages, such as. 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. Common applications in which Flexible PVC is used include: Plastic Molded Concepts, Inc. P.O. PVC is most commonly used in plumbing and drainage applications, although it's also sold in the form of pellets or as resin in its powder form.

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. Rigid PVC can be offered in clear, opaque, weather resistant, high tensile strength and impact resistant formulations that are easily machined. Plasticized (Flexible) Polyvinyl Chloride (PVC-P) PVC-P is a thermoplastic, further classified as a polyvinyl plastic. A highly versatile polymer, PVC is compatible with many additives. Hardness, Rockwell 110-120 ASTM D785. 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. Several alloys and copolymers are possible with PVC, including styrene and acrylonitrile. PVC: RPVC (1.3–1.45 g cm-3) is denser than FPVC (1.1–1.35 g cm-3). PVC is a thermoplastic polymer. Flexible PVC is a vinyl polymer. Standard physical properties including tensile strength, elongation, toughness, modulus, tear resistance, and barrier characteristics were evaluated for all films. 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. By adjusting the type and amount of plasticizers, plastic molders can achieve a large range of flexible compositions. Common Names: PVC (polyvinyl chloride) Temperature Range.
