Offered in a wide range from rubbery soft to semi-rigid, Flexible PVC is widely used for plastic profile extrusions because of … It's currently ranked as the third most widely used plastic in the world (behind polyethylene and polypropylene). 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. PVC Pipe. This is due to its plasticizer content. They are soft and flexible in nature; their Tgs are less than room temperature. Flexible PVC offers a number of advantages, such as. Water Absorption % increase. 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. To avoid improper resin selection, Contact PMC for additional help in determining the exact engineering resin required for your application. However, plasticized PVC has a lower melting point, is less resistant to chemicals, and has a lower ultimate tensile strength than rigid vinyl. Applications include: Identifying the Tg of polymers is often used for quality control and research and development. Polyvinyl chloride (PVC) is one of the earliest industrialized plastic. 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. Polyvinyl Chloride or also known as PVC comes in two basic forms. Does flexible PVC film have good electrical properties? PVC has been used extensively in a wide range of construction products for over half a century. This solid form can then be modified with the addition of fillers and plasticisers depending on the task at hand. So if your film will only be exposed to a heat environment below 60C/140F, flexible PVC film is a good choice. Low Temperature Usage: -40 degrees C | 5 degrees C; High Temperature Usage: 60°C | 140°F; Tensile Strength. It was the 1950s when PVC started to replace rubber insulated and sheathed cables in general household wiring due to its ease of processing.

PVC, Rigid Rigid PVC Resin Properties & Uses. 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. PVC's strong, lightweight, durable and versatile characteristics make it ideal for window profiles. The softer the film, the more plasticizer, the lower temp it melts at. 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. Please Note: PMC does not sell the material listed below. Its current output is outranked only by polyethylene, since it exhibits corrosion resistance and good insulation properties for many purposes. Flexible PVC. Rigid PVC has an oxygen index of 45-50, compared to 21-22 for wood and 17-18 for most thermoplastics. 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). Cell Classification 12454 ASTM D1784. Flexibility can be increased over a wide range by adding varying amounts of several plasticizers such as dioctyl phthalate. 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.
