In technical terms, the particular versatility of PVC allows for precise adjustments to its material properties to give the exact performance and quality requirements for specific end-use applications.
PVC’s main automotive applications are:
1. Underbody coatings, sealants and floor modules.
2. Wire harnesses (e.g. cable insulation and grommets).
3. Passenger compartment parts (e.g. dashboard and door panels seating and […]
1.Extrusion: Sheet, film, pipe, profiles (all flexible or rigid), coated wire and cable (flexible coating)
2.Injection molding: Pipe fittings, electrical fittings, gaskets, footwear (including micro cellular soles)
3.Calendering: Sheet, film (flexible or rigid), flooring and floor tiles (flexible)
4.Compression molding: Thin sheeting or laminates, cellular articles
5.Blow Molding: Bottles and other containers
6.Paste Processing (Coating by Dipping, Spreading or Transfer […]
At first glance, PVC and CPVC pipe look the same, but they aren’t. Although they are both a type of plastic plumbing pipe, they vary in composition and outside diameter. For this reason, you cannot simply join the two types of plastic with a coupling. You can, however, solvent-weld a special fitting designed to compensate […]
Lead-based stabilizers used within PVC formulations are immobilized in the plastic matrix in much the same way as they are within traditional glass products made from lead crystal, and lead compounds will not be released during the service life of the articles.
The Risk assessment on lead shows that the use of lead stabilizers is safe […]
Lead is an abundant metal which has been exploited since mining began in ancient historical times. In 1998 lead consumption in OECD countries amounted to 5.2 million tonnes (6 million tones worldwide). The principal uses of lead are shown in the table below.
Lead has the longest history as a stabiliser for PVC. Lead compounds are a […]
PVC is extensively used for municipal water supply/sewage pipes, spouts, profiles, etc., since its mechanical properties such as tensile strength and tensile modulus are better than those of other general purpose olefin plastics, and these products are robust and durable.
When plasticisers are added, PVC shows rubber-like elasticity with high tensile strength and fatigue strength, and […]
Of the PVC produced by Western European manufacturers in 1998, around six percent was used in consumer goods. New uses are being found all the time because the versatility of PVC allows it to compete with many materials such as metal, wood and glass in our everyday lives.
A good example of how PVC can be […]
All polymers, including PVC, require the use of additives. For rigid PVC formulations these are stabilisers, modifiersand lubricants. For bendable PVC, plasticisers are also used to achieve flexibility.
Other additives may include processing aids and pigments. These are selected from food contact approval lists – such as those regulated at national level within Europe or US […]
Since PVC has a high polarity and high compatibility with a variety ofother high-performance plastics, it is possible to mix these easily to form polymeralloys. By polymer alloying techniques some of the shortcomings of rigid PVCproducts can be modified. Fig.1 shows the outline of property modificationthrough polymer alloying.
In addition to the polymer alloying technique, modifications […]
PVC is one of the most used plastic materials in the world. At global level, demand for PVC exceeds 35 million tonnes per annum and it is in constant growth (+5% on global average), with higher growth rates in the developing countries.
In Europe(EU-27), the production of PVC products – including exports – totals about 8 million […]
