   Plastic plate and other materials have the following characteristics
   <1> Light weight and rugged

   < 2> Easy to produce in large quantities, cheap

    <3> Wide range of applications, easy to color, some high temperature

    <4> Chemical resistance

   <5> Surface gloss, partially transparent or opaque for good insulator
   Plastic plates are also divided into general plastics and engineering plastics, mainly used to define the breadth of the use, such as PE board, PP board cheap, can be used in a variety of different types of machine production (such as extruder, laminator) The Engineering plastics are more expensive, but the stability of raw materials and physical properties are much better, in general, it has both rigidity and toughness of the two characteristics. Has good corrosion resistance, high strength, hardness, easy processing and welding and other characteristics, widely used for acid and alkali pond, extraction containers, and other chemical, water treatment, environmental protection equipment.
   Plastic plate with excellent chemical stability, corrosion resistance, hardness, high strength, anti-ultraviolet (anti-aging), fire-retardant (with self-extinguishing), reliable insulation, smooth surface, smooth, Deformation, easy processing, etc., is an excellent thermoforming material, can replace part of the stainless steel and other corrosion-resistant synthetic materials, is widely used in chemical, oil, electroplating, water purification equipment, environmental protection equipment, mining, extraction engineering, Board, fire board template, Mianshaozhuan pallets, architectural templates and advertising decoration and other industries.
   PVC board performance
   General performance PVC resin is a white or light yellow powder, the relative density of 1.35-1.45. The degree of softness and hardness of the product can be adjusted by adding the number of parts of the plasticizer. Pure PVC water absorption and permeability are few.
   Mechanical properties Mechanical properties PVC has a high hardness and mechanical properties. And increased with the increase of molecular weight molecular weight, but decreased with the increase of temperature. Hard PVC mechanical properties, and its elastic modulus up to 1500-3000MPa and soft PVC elasticity of 1.5-15MPa, but the elongation at break up to 200% -450%. PVC friction in general, the static friction factor 0.4-0.5, dynamic friction factor dynamic friction factor of 0.23.
   Thermal properties of PVC heat stability is very poor, 140 ℃ began to break down, the melting temperature of 160 ° C. PVC linear expansion coefficient is small, with flame retardant, oxidation index of up to 45 or more.
   Electrical properties Electrical propertiesPVCis a good electrical properties of the polymer, but because of its large polarity, electrical insulation than PP and PE. Dielectric constant, dielectric loss tangent and volume resistivity, resistance to corona is not good, generally suitable for low and low frequency insulation materials.
   Environmental performance: PVC can withstand most of the inorganic acid base, salt, most organic solvents. Suitable for medicine, chemical anti-corrosion materials.
