Difference Between Lexan (Polycarbonate) and PVC(Vinyl, Wall Decals Material)

Lexan PC sheet, also called polycarbonate sheet, is an engineering plastic with excellent overall performance. PVC or Vinyl is the abbreviation of polyvinyl chloride, which is a polymer made by the polymerization of vinyl chloride monomer under the action of peroxide, azo compounds and other initiators; or by the mechanism of free radical polymerization reaction under the action of light and heat. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively called vinyl chloride resins.

1. What is PVC (or Vinyl, Wall Decals Material)

PVC is the abbreviation of polyvinyl chloride, which is a polymer made by polymerization of vinyl chloride monomer under the action of initiators such as peroxides and azo compounds, or by free radical polymerization reaction mechanism under the action of light or heat. Vinyl chloride homopolymer and vinyl chloride copolymer are collectively called vinyl chloride resin. vinyl is currently the second most produced general-purpose plastic and the most widely used plastic, PVC itself is also a colorless and transparent hard material, but it is much more brittle than PC, and its transparency is not as good as PC, and its other mechanical properties are also very different from PC. The so-called hard PVC is the PVC plasticizer added to 100 kg of PVC resin powder less than 5 kg of PVC plastic plastic, such as construction pipes, downspouts, plastic windows, credit cards and so are hard PVC. plasticizer added more than 5 kg is called semi-hard PVC, more than 25 kg is called soft PVC.

One of the major applications of vinyl in life is wall stickers.

You can find them everywhere online. The peel & stick vinyl wall decal is a smooth, satin finished product that is easy to install and totally removable! The vinyl wall material is also adjustable, featuring air-release channels allowing air to escape, resulting in a lower occurrence of air bubbles. The vinyl material is also adjustable, featuring air-release channels allowing air to escape, resulting in a lower occurrence of air bubbles, making it the preferred vinyl decal materials for wrapping vehicles such as cars, trucks, boats, and trailers. The vinyl material is available in either a glossy or matte scratch, uv, and water Transform your home or business with a custom wall decal. We found this wall stickers maker has the most various selection of the stickers used in life. Make a personal logo, quote or family portrait come to life with a wall decal. Easy to apply and you won’t be left with any sticky residue behind. Custom wall decals can make any space stand out and look professional. PVC can also be colored at will and made into various transparent and opaque colored products, so PVC is the most versatile plastic at present, and the price is only about 1/2 to 1/4 of PC.

The outstanding advantages of PVC products are its incombustibility, abrasion resistance, chemical resistance, and low leakage of gas and water vapor. In addition, the comprehensive mechanical properties, product transparency, electrical insulation, heat insulation, muffling, shock absorption, is the most superior performance to price ratio of general-purpose materials. The disadvantage is that the thermal stability and impact resistance are poor, and both hard and soft PVC are easy to produce brittleness in the process of use; PVC is most commonly used and cheap.

2. What is Lexan Polycarbonate

Lexan is Polycarbonate, a colorless, transparent, unqualified thermoplastic material. Known as a transparent alloy with very high mechanical strength, polycarbonate is colorless, transparent, heat resistant, impact resistant, flame retardant, and has UL94 V-0 grade flame retardant properties without additives. Because of its colorless transparency and excellent impact resistance, common daily applications include optical discs, resin eyeglass lenses, mugs, kitchenware (juicers, etc.), bulletproof glass, goggles, headlights, etc. PC is only available in rigid. PC is only available in rigid form. PC sheet is a high quality bar material made of polycarbonate as the main component using co-extrusion technology. Because its surface is covered with a high concentration of ultraviolet absorbers, in addition to its anti-UV characteristics and can maintain long-term weathering, never fade. Polycarbonate has high strength, high impact toughness, high glass transition temperature, and heat resistance, PC material working temperature between -60 ℃ to 120 ℃. It is a high-tech, extremely excellent overall performance, energy-saving and environmentally friendly plastic sheet, and is a commonly used plastic building material internationally.

PC sheet is the king of transparent plastics and is an engineering plastic with exceptionally good performance. pc sheet is basically indestructible and can bear great force. pc sheet is easy to be processed for finishing. All kinds of paints and lacquers can be evenly coated on the density board, which is the base material for doing the painting effect. A variety of veneer panels, films, decals and other materials can be glued on the surface of PC board. The impact strength is still very high, and the scale stability performance is good, but also colorless and lucid, coloring performance is also good, electrical insulation as well as corrosion resistance, wear resistance is good. Such excellent properties also lead to the expensive price of PC, but the strength is high and the time spent is relatively long.

3. What is the Difference Between PVC Vinyl and Lexan Polycarbonate

  • PC is polycarbonate plastic, which belongs to the category of engineering plastics, with good transparency, high strength and good weather resistance, and is often used for optical products, optical discs, sunlight panels, etc.
  • PVC is polyvinyl chloride plastic, belongs to the general plastic category, hard (without plasticizer) PVC products are often used for plastic doors and windows, water pipes, threading pipes, plates, etc., soft (with plasticizer) PVC products are often used in film, soft board, soft sheet, hose, medical products (such as infusion bags, etc.).
  • PC is the engineering plastics of the three major applications are glass assembly industry, automotive industry and electronics, electrical industry, followed by industrial machinery parts, CD-ROM, packaging, computers and other office equipment, medical and health care, film, leisure and protective equipment, etc. PC can be used as windows and doors glass, PC laminates are widely used in banks, embassies, detention facilities and public places of protective windows, for aircraft hatches, lighting equipment PC laminates are widely used in banks, embassies, detention and public places for protective windows, aircraft hatch covers, lighting equipment, industrial safety panels and bulletproof glass.
  • PVC is one of the most produced plastic products in the world, cheap and widely used, PVC resin is white or light yellow powder. Depending on the application, different additives can be added, and PVC plastic can show different physical and mechanical properties. By adding the right amount of plasticizer to PVC resin, a variety of hard, soft and transparent products can be made. With the booming development of domestic automotive, electrical, electronic and communication machinery industry, the demand for modified engineering plastics will rise significantly, and various high-strength and heat-resistant engineering plastics will be widely used. Polymer alloys, especially nylon alloys and PC alloys, will be favored by the market. Green environmental protection concept will be introduced into the modified engineering plastics industry, and the recycling of various scrap will become a common concern in the industry. The concept of reuse and environmental protection will be integrated into the design and manufacturing process of modified polymers.

4. How much do you know about plastics?


Plastics are plastic (flexible) materials that are formed by processing with high molecular weight synthetic resin/petroleum as the main component and adding appropriate additives, such as plasticizers, stabilizers, antioxidants, flame retardants, lubricants, colorants, etc., or rigid materials formed by curing and cross-linking.

Plastic waste is difficult to decompose naturally, and if it flows into the ocean, it can lead to marine life accidentally eaten, suffocation, poisoning, etc., affecting marine ecology; incineration of plastic waste can also cause air pollution, polyvinyl chloride (PVC) and polycarbonate (Polycarbonates) and other plastics, even under certain conditions will release harmful substances or endocrine disruptors, endangering biological reproductive function.
