What are the characteristics of PVC, the role?
- PVC (polyvinyl chloride), the simple structure of its monomer CH2 = CHCl
Chemical and physical properties:
Rigid PVC is one of the most widely used plastic materials.PVC is actually a vinyl polymer, its material is a non-crystalline material.PVC material in the actual use of often added stabilizer, lubricant, auxiliary processing agent , Colorants, impact agents and other additives. Has a non-flammability, high strength, weather resistance and excellent geometric stability of PVC on oxidants, reducing agents and strong acid has a strong resistance, but it can Strongly oxidized acid such as concentrated sulfuric acid, concentrated nitric acid corrosion and does not apply with aromatic hydrocarbons, chlorinated hydrocarbons in contact with the occasion.
PVC melting temperature during processing is a very important process parameter, if this parameter will lead to improper decomposition of the material. PVC flow characteristics are quite poor, its process range is very narrow. Especially large molecular weight PVC material is more difficult to process (this The material is usually added to the lubricant to improve the flow characteristics), so usually used are small molecular weight PVC material PVC shrinkage is quite low, generally 0.2 to 0.6%.s
What are the noncombustible materials?

PU wallboard and PVC wallboard, which is better
- Its characteristics are weathering, energy saving, heat insulation, insulation, no radiation, high strength, light weight, easy to install, safe and reliable. It is suitable for both indoor and outdoor applications. PU series of wallboard to create a American pastoral style, Mediterranean style, personality avant-garde style, neoclassical style, simple styles
Integrated wallboard is not pvc do?
- With excellent sound insulation and surface texture and facial decoration, diversification of dual functions. Inorganic high-strength sound insulation decorative panels sound insulation effect, the board surface treatment process types, there are different texture and imitation wood grain, imitation stone pattern, abstract pattern, etc., at the same time to achieve smooth, smooth, beautiful, realistic decoration Effect, and the product is not only high strength, toughness structure is good, with "self-breathing air purification, wet warm insulation" function, at the same time with wear, weather, fire, moisture, zero formaldehyde and other good physical properties.s
Will the PVC wall panels have no pollution?
- PVC has a strong resistance to oxidants, reducing agents and strong acids. However, it can be strongly oxidized acid such as concentrated sulfuric acid, concentrated nitric acid corrosion and does not apply with aromatic hydrocarbons, chlorinated hydrocarbons in contact with the occasion.s
What is the difference between PVC integrated wallboard and wood fiberboard?
- PVC integrated wall panels are often cheaper, and bamboo fiberboard to be slightly more expensive. In addition, PVC for a long time will appear hot up the phenomenon of cold, and bamboo fiber will not.s
Pvc wall board toxic?
- PVC is actually a vinyl polymer, the material is a non-crystalline material.s
