Generally, PVC board will break when the impact force exceeds the toughness force. Sometimes, too low temperature will reduce longitude and toughness, and too few reinforcing and toughening agents will also cause easy fracture. If the processing temperature is too high and too low, it is easy to fracture without good plasticizing effect. Today, let's take a look at the properties of this material.
PVC plate is a kind of chemical plate. The material is very soft, so the weight of PVC products is very small and it is easy to move. The cabinet made of this chemical material does not absorb water, nor will it expand and deform like wood. But its formaldehyde content is very high, so it is a heavily polluted material. In addition, PVC cabinets have poor resilience, easy fading and high temperature resistance.
1. the density of pure polychlorinated nitrobenzene is 1.4g/cm. The density of PVC plastic parts containing plasticizer and filler is generally 1.15-2.00g/cm.
2. rigid PVC board has good tensile, bending, compression and impact properties, and can be used as structural material alone.
3. the softness, elongation at break and cold resistance of soft PVC board will increase, but the brittleness, hardness and tensile strength will decrease.
4. PVC has good electrical insulation performance, can be used as low-frequency insulation material, and has good chemical stability. Due to the poor thermal stability of PVC, heating for a long time will lead to decomposition, release hydrogen chloride gas, and discoloration of polychlorinated nitrobenzene. Therefore, its application range is narrow, and the application temperature is generally between 15~55 ℃.
5. PVC board is PVC, a kind of plastic product synthesized by 43% oil and 57% salt. Compared with other kinds of plastic products, PVC uses raw materials more effectively and reduces fuel consumption. At the same time, the energy consumption of PVC manufacturing industry is also very low. In addition, PVC products can be recycled and converted into other new products or incinerated to obtain energy for later use.
