What is polycarbonate sheet<\/b><\/strong>\uff1f<\/b><\/strong><\/h1>\n

Polycarbonate sheet (PC) is a group of thermoplastic polymers containing carbonate groups in chemical structure. The polycarbonate sheet used in the project is a strong and tough material, and some grades are optically transparent. They are easy to process, form and heat form. Because of these characteristics, polycarbonate has found many applications. Polycarbonate has no resin identification code (RIC) of xxx and is identified as “other” in the RIC list, 7. Products made from polycarbonate may contain the precursor monomer bisphenol A (BPA).<\/p>\n

Properties and processing editing of polycarbonate<\/b><\/strong><\/h3>\n

Polycarbonate is a durable material. Although it has high impact resistance, its scratch resistance is very low. Therefore, the hard coating is applied to polycarbonate glasses and polycarbonate external automotive components. Compared with polymethylmethacrylate (PMMA, acrylic acid), polycarbonate has stronger properties and longer retention time at extreme temperatures. Heat treatment materials are usually completely amorphous, so they are highly transparent to visible light and have better light transmittance than many kinds of glass.<\/p>\n

The glass transition temperature of polycarbonate is about 147 \u00b0 C (297 \u00b0 F), so it gradually softens above this temperature and flows above about 155 \u00b0 C (311 \u00b0 F). The tool must be kept at high temperature, usually higher than 80 \u00b0 C (176 \u00b0 F), to produce strain-free and stress-free products. The low molecular weight grade is easier to form than the high grade, but its strength is therefore lower. The toughest brand has the highest molecular weight, but it is more difficult to process.<\/p>\n

Unlike most thermoplastics, polycarbonate can withstand large plastic deformation without cracking or fracture. Therefore, it can be processed and formed using sheet metal technology at room temperature, such as bending on the brake. Even for sharp bends with small radii, heating may not be necessary. This makes it valuable in prototype design applications that require transparent or non-conductive parts, which cannot be made of metal plates. PMMA\/acrylic, similar in appearance to polycarbonate, fragile, and cannot be bent at normal temperature.<\/p>\n
