PMMA韓國LG亞克力透明(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 perbance, 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.

亞克力性能
透明度優(yōu)良,有突出的耐老化性; 它的比重不到普通玻璃的一半,抗碎裂能力卻高出幾倍;它有良好的絕緣性和機械強度;對酸、堿、鹽有較強的耐腐蝕性能;且又易加工;可進行粘接、鋸、刨、鉆、刻、磨、絲網(wǎng)印刷、噴 PMMA
砂等手工和機械加工,加熱后可彎曲壓模成各種壓克力制品。
物理性能
聚甲基丙烯酸甲酯 (Polymethylmethacrylate,簡稱PMMA,英文Acrylic),又稱做壓克力或有機玻璃,在香港多稱做阿加力膠,它的鑄板聚合物的數(shù)均分子量一般為2.2×104,相對密度為1.19~1.20,折射率為1.482~1.521,吸濕度在0.5%以下,玻璃化溫度為105℃。具有高透明度,低價格,易于機械加工等優(yōu)點,是平常經(jīng)常使用的玻璃替代材料。 設(shè)計新穎、工藝先進、色調(diào)高雅、造型美觀。 1.PMMA的重量輕,密度比玻璃低:PMMA的密度大約在1150-1190 kg/m3,是玻璃(2400-2800 kg/m3)的一半。同樣大小的材料,其重量只有普通玻璃的一半,金屬鋁(屬于輕金屬)的43%。 2.PMMA的機械強度較高:有機玻璃的相對分子質(zhì)量大約為200萬,是長鏈的高分子化合物,而且形成分子的鏈很柔軟,因此,有機玻璃的強度比較高,抗拉伸和抗沖擊的能力比普通玻璃高7~18倍??估瓘姸葹?~7千克力/毫米2,耐壓強度為12~14千克力/毫米2,耐沖擊性比聚苯乙烯好;它還有不易破碎的特點。有一種經(jīng)過加熱和拉伸處理過的有機玻璃,其中的分子鏈段排列得非常有次序,使材料的韌性有顯著提高,用釘子釘進這種有機玻璃,即使釘子穿透了,有機玻璃上也不產(chǎn)生裂紋,這種有機玻璃被擊穿后同樣不會破成碎片。因此,拉伸處理后的有機玻璃可用作防彈玻璃,也用作軍用飛機上的座艙蓋。
