The new acrylic sheet is a kind of special organic glass treatment. Because of its good transparency and decorative effect, it is often used in home decoration products. There are three differences between recyclable materials and recyclable materials in acrylic sheets, including different grades and prices. Prices are part of the 2000-2000 years. Domestic boards are relatively cheap, while imported boards are a bit expensive. Acrylic sheets can be used in various specifications, generally: 122 * 244 cm, 122 * 183 cm, and other specifications 200 * 300 cm, the thickness is 0.1 to 5 cm, the weight of some acrylic sheets depends on the price, from tens to tens RMB/kg.
The new acrylic sheet can effectively prevent ultraviolet rays, and will not fade or yellow for at least 10 years. Weak anti-ultraviolet rays, light yellow, fading, not easy to crack. The light transmittance is greater than 93%. The light transmittance is less than 93% 85% or lower. The cross section is transparent and colorless, and the performance (thermal) is stable after processing. The slices are yellow, and the yellow is not obvious after the whitening agent is treated, and the yellow is short-term. After the odor-free treatment, heating and sunlight will increase the yellowing, resulting in a pungent odor and easy cracking. Excellent crack resistance and chemical resistance. No cracking, solvent resistance, and poor chemical properties. Excellent weather resistance. Resistance to bad weather. High-quality protective film provides excellent protection, and the packaging and protective film are relatively rough.
The brand-new acrylic sheet is mainly used for making sculptures, ornaments, and handicrafts, while the extrusion type is usually used for the production of billboards and light boxes. PMMA has the advantages of light weight, low price and convenient molding. The forming methods include casting, injection molding, machining, thermoforming, etc. In particular, injection molding can be mass-produced, with simple process and low cost. Therefore, its application is more and more extensive, widely used in instrument parts, automobile headlights, optical lenses, transparent tubes and other fields.
