Introduction to the basic characteristics and main uses of pvc raw materialsIntroduction to the basic characteristics and main uses of pvc raw materials
PVC skinning boards are gradually entering people's lives. You can see the traces of PVC skinning boards in every corner of life, but how much do you know about the basic characteristics and main uses of raw materials? I will give you a detailed introduction below:
It is one of the largest plastic products in the world with low price and wide application. PVC resin is white or light yellow powder. Different additives can be added according to different uses, and PVC plastics can exhibit different physical and mechanical properties. Adding an appropriate amount of plasticizer to PVC resin can make a variety of hard, soft and transparent products.
The density of pure polyvinyl chloride is 1.4g/cm3, and the density of polyvinyl chloride plastic parts added with plasticizers and fillers is generally 1.15-2.00g/cm3.
Rigid PVC has better tensile, bending, compression and impact resistance, and can be used alone as a structural material.
Soft PVC will increase in flexibility, elongation at break, and cold resistance, but brittleness, hardness, and tensile strength will decrease.
Polyvinyl chloride has good electrical insulation properties, can be used as low-frequency insulation materials, and its chemical stability is also good. Due to the poor thermal stability of polyvinyl chloride, prolonged heating will cause decomposition, release HCL gas, and change the color of polyvinyl chloride, so its application range is narrow, and the use temperature is generally between -15 and 55 degrees.
The main purpose:
Due to its high chemical stability, it can be used to make anticorrosive pipes, fittings, oil pipelines, centrifugal pumps and blowers. PVC hardboards are widely used in the chemical industry to make linings for various storage tanks, corrugated boards for buildings, door and window structures, wall decorations and other building materials. Due to its excellent electrical insulation properties, it can be used to manufacture plugs, sockets, switches and cables in the electrical and electronic industries. In daily life, PVC is used to make sandals, raincoats, toys and artificial leather!
