PMMA韩国LG亚克力透明(原材料)
Typical applications are automotive industry (signal lamp equipment, instrument panel, etc.) , pharmaceutical industry (blood storage container, etc.) , industrial applications (DVD, light scattering) , electronic product keys (especially transparent) . Consumer goods for daily use (beverage cups, stationery, etc). PMMA is soluble in organic solvents, such as phenol, anisole and so on. It can be used as the dielectric layer of organic field effect transistor (Ofets) . INJECTION MOLDING PROCESS CONDITIONS DRYING TREATMENT: PMMA with hygroscopicity so processing before the drying treatment is necessary. The drying condition of PMMA was suggested to be 90 °C for 2 ~ 4 hours. MELTING TEMPERATURE: 240 ~ 270 °C. Mould temperature: 35ー70 °C. INJECTION SPEED: medium chemical and physical properties PMMA has excellent optical properties and resistance to climate change characteristics. White light penetrates 92% . PMMA products with a very low birefringence, especially suitable for the production of video discs. PMMA has room temperature creep properties. With the increase of load and time, the phenomenon of stress cracking can be induced. PMMA has good impact resistance. PMMA surface hardness is not high, easy to scratch, impact resistance is low, poor flow molding performance, such as the shortcomings of PMMA has been modified. Such as methyl methacrylate and styrene, Butadiene Copolymerization, PMMA and PC blending. Super Transparent PMMA material mainly used for mobile phone screen protection, the product is divided into two hardening coating, no hardening coating. It is characterized by excellent light transmittance, no impurities, electrostatic protection film, surface hardening thick hardness up to 5-6 hours. Special recommendation for the hardening of PMMA materials, known as the domestic plate.

亚克力性能
透明度优良,有突出的耐老化性; 它的比重不到普通玻璃的一半,抗碎裂能力却高出几倍;它有良好的绝缘性和机械强度;对酸、碱、盐有较强的耐腐蚀性能;且又易加工;可进行粘接、锯、刨、钻、刻、磨、丝网印刷、喷 PMMA
砂等手工和机械加工,加热后可弯曲压模成各种压克力制品。
物理性能
聚甲基丙烯酸甲酯 (Polymethylmethacrylate,简称PMMA,英文Acrylic),又称做压克力或有机玻璃,在香港多称做阿加力胶,它的铸板聚合物的数均分子量一般为2.2×104,相对密度为1.19~1.20,折射率为1.482~1.521,吸湿度在0.5%以下,玻璃化温度为105℃。具有高透明度,低价格,易于机械加工等优点,是平常经常使用的玻璃替代材料。 设计新颖、工艺先进、色调高雅、造型美观。 1.PMMA的重量轻,密度比玻璃低:PMMA的密度大约在1150-1190 kg/m3,是玻璃(2400-2800 kg/m3)的一半。同样大小的材料,其重量只有普通玻璃的一半,金属铝(属于轻金属)的43%。 2.PMMA的机械强度较高:有机玻璃的相对分子质量大约为200万,是长链的高分子化合物,而且形成分子的链很柔软,因此,有机玻璃的强度比较高,抗拉伸和抗冲击的能力比普通玻璃高7~18倍。抗拉强度为6~7千克力/毫米2,耐压强度为12~14千克力/毫米2,耐冲击性比聚苯乙烯好;它还有不易破碎的特点。有一种经过加热和拉伸处理过的有机玻璃,其中的分子链段排列得非常有次序,使材料的韧性有显著提高,用钉子钉进这种有机玻璃,即使钉子穿透了,有机玻璃上也不产生裂纹,这种有机玻璃被击穿后同样不会破成碎片。因此,拉伸处理后的有机玻璃可用作防弹玻璃,也用作军用飞机上的座舱盖。
