显示器用PMMA塑料光学级

产品详细信息显示器用PMMA塑料光学级PMMA的密度低于玻璃：PMMA的密度约为1.15-1.19 g/cm，是玻璃（2.40-2.80 g/cm）和金属铝（属于轻金属）的一半。PMMA塑料光学级

PMMA具有较高的机械强度：PMMA的相对分子质量约为200万。它是一种长链聚合物，分子链非常柔软。因此，聚甲基丙烯酸甲酯具有较高的强度和抗拉伸和冲击性。它比普通玻璃高7到18倍。有一种加热和拉伸的有机玻璃，其中分子段以非常有序的方式排列，从而显著提高材料的韧性。钉子被钉入有机玻璃中，即使钉子穿透，也不会产生裂缝。这种有机玻璃被子弹击碎后不会碎裂。因此，拉伸的PMMA可以用作防弹玻璃，也可以用作军用飞机的遮篷。PMMA塑料光学级在日常生活中，最常见的是显示器，如电脑、平板电脑、电子仪器等。聚甲基丙烯酸甲酯塑料光学级聚甲基丙烯酸甲酯的熔点较低：聚甲基丙烯酸甲酯的熔点约为130-140°C（265-285°F），远低于约1000度玻璃的温度。PMMA塑料光学级PMMA具有高透光率。可见光：PMMA是目前最优秀的聚合物透明材料，其透光率为92%，高于玻璃。PMMA塑料光学等级

Product Details

PMMA plastic optical grade for display

The density of PMMA is lower than that of glass: the density of PMMA is about 1.15-1.19 g/cm, which is half of glass (2.40-2.80 g/cm) and 43% of metallic aluminum (belonging to light metal).PMMA plastic optical grade

PMMA has high mechanical strength: PMMA has a relative molecular mass of about 2 million. It is a long-chain polymer and the molecular chain is very soft. Therefore, PMMA has high strength and resistance to stretching and impact. It is 7 to 18 times higher than ordinary glass. There is a heated and stretched plexiglass in which the molecular segments are arranged in a very orderly manner, resulting in a significant increase in the toughness of the material. The nail is nailed into the plexiglass, and even if the nail penetrates, no crack is generated. This kind of plexiglass will not break into pieces after being broken by bullets. Therefore, the stretched PMMA can be used as a bulletproof glass and also as a canopy on a military aircraft.PMMA plastic optical grade

In daily life, the most common are displays, such as computers, tablets, electronic instruments, and so on.PMMA plastic optical grade

The melting point of PMMA is lower: PMMA has a melting point of about 130–140 ° C (265–285 ° F), which is much lower than the temperature of about 1000 degrees of glass.PMMA plastic optical grade

PMMA has a high light transmittance. Visible light: PMMA is currently the most excellent polymer transparent material, and its light transmittance is 92%, which is higher than that of glass.PMMA plastic optical grade
