在塑料中具有*高的耐冲击强度值,且该特性高于铸锌和铸铝。
使用温度范围
在低温到高温很宽的范围内仍可保持稳定的特性。
电学特性
在很宽的温度范围内使用时变化很小,可作为优良的绝缘材料。
透明性
具有塑料中少有的优异透明性,适合光学及板材用途。
尺寸稳定性
具有优良的耐蠕变性能,尺寸几乎不受吸湿、温度、时间变化的影响。
阻燃性
具有优良的阻燃性,通过了UL规格Subject94的V-0、V-1、V-2、HB、5VA、5VB等级测试。
主要优点
1.具高强度及弹性系数、高冲击强度、使用温度范围广;

PC plastic adhesive according to different needs, you can choose the following adhesives: 1. G -933: one-component room-temperature cured soft elastic anti-shock adhesive, high and low temperature resistance, different viscosity bonding speed several seconds to several hours after curing. 2. KD-833 instant adhesive, can be a few seconds or tens of seconds fast bonding PC plastic, but the rubber layer is hard and brittle, not resistant to 60 degrees above hot water immersion. 3. QN-505, two-component adhesive, soft adhesive layer, suitable for large area of PC plastic bonding or composite. But the high temperature resistance is poor. Four. QN-906: two-component adhesive, high temperature resistance. 5. G-988: one-component room temperature vulcanizate, cured elastomer with * * waterproof, shockproof adhesive, resistant to high and low temperature, 1-2 mm thickness, 10 minutes or so to start curing, 5-6 hours basic curing, have a certain strength. It takes at least 24 hours to fully cure. Single component, no need to mix, after extrusion can be smeared static, without heating. 6. Kd -5606: UV curing adhesive, adhesive transparent PS sheet and plate, can achieve no trace effect, need to use UV lamp irradiation curing. The effect is beautiful after gluing. But the high temperature resistance is poor.
