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. This suspension, a "plastisol," is then heated resulting in a homogenous system which becomes a flexible solid upon cooling. Low Temperature Usage: -40 degrees C | 5 degrees C; High Temperature Usage: 60°C | 140°F; Tensile Strength. By adjusting the type and amount of plasticizers, plastic molders can achieve a large range of flexible compositions. Hardness: Rigid PVC is very hard. Polyvinyl chloride (PVC) is one of the earliest industrialized plastic. 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's currently ranked as the third most widely used plastic in the world (behind polyethylene and polypropylene). Pipe, extruded wire covering, toys, bottles, door and window components, film and fabric coatings. Recently discovered health hazards due to extended exposure to the vinyl chloride monomer have resulted in strict production controls. What is the heat resistance of flexible PVC film and sheets?

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. See also polyvinyl chloride/vinylidene chloride. Properties of PVC and HDPE. The softer the film, the more plasticizer, the lower temp it melts at. Standard physical properties including tensile strength, elongation, toughness, modulus, tear resistance, and barrier characteristics were evaluated for all films. Rigid PVC can be offered in clear, opaque, weather resistant, high tensile strength and impact resistant formulations that are easily machined. Offered in a wide range from rubbery soft to semi-rigid, Flexible PVC is widely used for plastic profile extrusions because of … 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. Unmodified polyvinylchloride is a very rigid thermoplastic. The Seiden Crystal is an antistatic and fire retardant transparent PVC film for cleanrooms, flexible partitions and containment solutions. The films were conditioned according to ASTM D 882 and then tested following the ASTM methods indicated in Tables II–IV. Value Test Method. There are, therefore, many different PVC products available with varying additive compositions and properties. PVC's inherent flame retardant and excellent electrical insulation properties make it ideal for cabling applications. It was the 1950s when PVC started to replace rubber insulated and sheathed cables in general household wiring due to its ease of processing. Flexible PVC (Polyvinyl Chloride) Unmodified polyvinylchloride is a very rigid thermoplastic. So if your film will only be exposed to a heat environment below 60C/140F, flexible PVC film is a good choice. Material Notes: This property data is a summary of similar materials in the MatWeb database for the category "PVC, Extruded". Flexible PVC film starts to soften at 60C/140F. PVC is a thermoplastic polymer. 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. Water Absorption % increase. We only use the material list to inform visitors that we are experienced in processing these materials for many fine products. Rigid PVC has an oxygen index of 45-50, compared to 21-22 for wood and 17-18 for most thermoplastics. GENERAL. PVC, Rigid Rigid PVC Resin Properties & Uses. It has a high strength-to-weight ratio and is a good electrical and thermal insulator. This solid form can then be modified with the addition of fillers and plasticisers depending on the task at hand. flexible PVC suitable for food packaging to keep meat and other perishable produce fresh (when FDA approved). Cell Classification 12454 ASTM D1784. PVC Properties. Its current output is outranked only by polyethylene, since it exhibits corrosion resistance and good insulation properties for many purposes. PVC's strong, lightweight, durable and versatile characteristics make it ideal for window profiles. They are also used in packaging (blisters). A frequent method of processing PVC involves the suspension of solid particles of the polymer in an appropriate plasticizer.

AuroraFlex™ SBS and SEBS compounds utilize multiple TPE/TPR chemistries to impart high-performance properties for durability and easy processing. DEHP is used in PVC for applications like blood bags, intravenous bags, flexible tubing, catheters, and protective gloves. PVC, or polyvinyl chloride, is a common thermoplastic and has uses in a variety of applications. FLEXIBLE. What are the Characteristics of Polyvinyl Chloride (PVC)? 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. Flexible or plasticised PVC compounds, with a wide range of properties, can also be produced by the addition of plasticisers. They are soft and flexible in nature; their Tgs are less than room temperature. The significance of this is that most rigid and flexible PVC will not burn alone without the … PVC comes in two forms (rigid PVC – RPVC and flexible PVC – FPVC), and some of their properties slightly vary. 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.

Polyvinyl Chloride or also known as PVC comes in two basic forms. Flexible PVC is a soft, flexible material that ranges in appearance from transparent to opaque. These materials have many of the same properties as vulcanized rubber, but can be molded and extruded using conventional thermoplastic process equipment. 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. Please Note: PMC does not sell the material listed below. This is due to its plasticizer content. Does flexible PVC film have good electrical properties? Hazen-Williams Factor C=150. To avoid improper resin selection, Contact PMC for additional help in determining the exact engineering resin required for your application. Flexible PVC is a soft, flexible material that ranges in appearance from transparent to opaque. PVC offers excellent corrosion and weather resistance. However, plasticized PVC has a lower melting point, is less resistant to chemicals, and has a lower ultimate tensile strength than rigid vinyl. Key mechanical properties include tensile, flex, compression and impact. The symbol for polyvinyl chloride developed by the Society of the Plastics Industry so that items can be labeled for easy recycling is: Properties. PVC has been used extensively in a wide range of construction products for over half a century. 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. Polyvinyl chloride (PVC) is a popular thermoplastic that's odorless, solid, brittle, and generally white in color. It has a very low tensile strength and a moderately high ductility among thermoplastics. Flexibility can be increased over a wide range by adding varying amounts of several plasticizers such as dioctyl phthalate. It’s not as resistant to high temperatures, but it excels in low temperature applications. We only use the material list to inform visitors that we are experienced in processing  these materials for many fine products. Flexible PVC is a vinyl polymer. 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. 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).
