What is the difference between PVC transparent board and acrylic?
1. Transparency and environmental protection, acrylic (PMMA) environmental protection is better than PVC, and some manufacturers' PVC may add plasticizers (plasticizers) in their formulations, and the plasticizer is not good.
2, transparency: Acrylic (PMMA) transparency should be good.
3, in addition, the price of PVC is cheap, the raw material of acrylic (PMMA) is expensive.
PVC
(1) Stereo words can be made into various illuminating characters, do not emit light or various advertising identifiers, such as guidelines, billboards, spiritual forts, and more.
The PVC can be divided into soft PVC and hard PVC. The hard PVC accounts for about 2/3 of the market, and the soft PVC accounts for 1/3.
(2) Hardness PVC board: The product quality implements GB / T4454-1996, has good chemical stability,Corrosion resistance, high hardness, high strength, high strength, anti-UV (aging), refractory flame retardant (self-extinguishing), reliable insulation, smooth surface, non-water, non-deformed, easy processing, etc.
This product is a superior thermoforming material that can replace some stainless steel and other corrosive synthetic materials, which are widely used in chemical, petroleum, electroplating, water purification processing equipment, environmental equipment, mines, pharmaceutical, electronics, communications and decoration.
(3) PVC transparent board: A high strength, high-transparent plastic plate produced by the advanced imported raw material. The product has a variety of varieties such as white, gemlan, tea, brown.The product is high in strength, high transparency, weather resistance, non-toxic, hygiene and physical properties than plexiglass. Widely used in equipment guards, interiors, drinking sinks, liquid level display, etc.

Acrylic board
(1) "Acrylic" is a sound translation, and English is acrylic. It is a chemical material. Chemical name is "PMMA" polyacrylate,Commonly known as "special treatment organic glass", the raw materials of acrylic in the application industry are generally in the form of particles, sheet materials, pipes.
(2) Acrylic also known as specially treated organic glass, is the organic glass replacement product, with acrylic production, the light box made is good, the color is pure, the color is rich, beautiful and flat, and the daylight is two effects.Long service life, does not affect the characteristics of use,In addition, acrylic sheets are perfectly combined with aluminum plastic sheet profiles, advanced wire screen printing, etc.
(4) Acrylic extruded plate: The molecular weight of the extrudate is low, the mechanical properties are slightly weaker than the cast plate. However, this feature is conducive to the bending and thermoforming processing, when processing a larger sheet material.At the same time, the thickness tolerance of the extrudate is smaller than the cast plate. Since the extrusion plate is a large amount of automated production, the color and specifications are inconvenient, the product specifications are subject to certain restrictions.
(5) Features: Solvent resistance: polymethyl methacrylate can be resistant to a thinner inorganic acid, but concentrated inorganic acid can cause it to erode, alkali,However, but warm sodium hydroxide, potassium hydroxide can molate, salt, salt, fatty hydrocarbons, dissolved in water, methanol, glycerol, etc.However, the absorption of alcohol is absorbed, and the stress cracking, no ketone resistance resistance, chlorocene and aromatic hydrocarbon. Its solubility parameter is about 18.8 (J / cm3) 1/2,Dissolved in many chlorine and aromatics, such as dichloroethane, trichlorethylene, chloroform, toluene, ethylene and acetone can also dissolve it.Polymethyl methacrylate has good resistance to gases such as ozone and sulfur dioxide.
Heath resistance: polymethyl methacrylate has excellent atmospheric aging, and the sample is natural aging test, weight change,The tensile strength, the light transmittance is slightly decreased, the color is slightly yellow, and the anti-silver rinse decline is more significant, and the impact strength is also slightly improved, and other physical properties have almost no change.
