Application and Characteristics of PVC Material

PVC (polyvinyl chloride) is a high molecular material obtained by polymerizing vinyl chloride monomer (VCM). Due to its low price and excellent performance, PVC has become the third most widely used general synthetic resin after polyethylene and polypropylene.

In 1912, German chemist Fritz Klatte first synthesized PVC and applied for a German patent. However, during his patent period, he was unable to develop suitable commercial products.

In 1926, Walde Semon of B.F.Goodrich in the United States synthesized PVC and applied for a patent in the United States. They improved PVC by adding various additives, making it more flexible and easier to process. This improvement made PVC quickly gain widespread commercial applications and become an important plastic material.

                                                                               

Characteristics: acid and alkali resistance, flame retardant, insulation, poor light and heat stability, stable agents need to be added during application; PVC must be used with plasticizers during application, and the material state can change from soft and elastic to hard and brittle.

Sensory characteristics: visual: matte, adjustable transparency, medium gloss; tactile: soft and warm; auditory: low pitch; olfactory: no odor.

Shape: resin granules, pipes, profiles including sheets, plates, rolls, fibers, foam, films, coatings Classification - Polyvinyl chloride (PVC) comes in two basic forms: rigid and flexible.

Rigid PVC products are used for pipes, window and door profiles, bottles, and credit or membership cards, while flexible PVC products are used for hoses, electrical wires and cables, insulation, hoses, and other profiles.

Applicable processes - calendering, extrusion, injection molding, blow molding

Applications - building materials - pipes, components, window frame profiles, waterproofing membranes, flooring; electronics - wires, cables, tape, plugs; others - dashboard foam panels, packaging, film, bottles, etc.

Building materials - PVC is a very durable material and is widely used in the construction industry. Due to its high chemical stability, it has high mechanical strength and good corrosion resistance; flame retardant; inner wall smooth, low fluid flow loss; light weight, easy transportation and installation, so it is often used in building materials for drainage systems.

Toys - PVC can be produced through almost all plastic processing methods, processing is simple, cost-effective, easy to color, so PVC is also widely used to manufacture toys.

As a material that comes into contact with the human body, the use of plasticizers in PVC products for toys and other skin-contact applications is often a matter of concern. In the future, the use of non-toxic and environmentally friendly plasticizers in PVC products will be the main trend. Synthetic Leather - PVC synthetic leather is a composite material made by coating or laminating a mixture of PVC resin and certain additives onto a base material and then processing it, which is similar to natural leather and has the characteristics of vibrant appearance, soft texture, wear-resistant, fold-resistant, acid and alkali resistance, etc.

PVC synthetic leather classification, from the point of view of use can be divided into shoe, luggage, floor materials and other several kinds. Product design Industrial design Design inspiration CMF design PVC.
