The performance of the PC endurance plate?

by:GWX     2020-08-26

endurance plate manufacturers come to the conclusion that the performance of the PC board is as follows:

optical performance

light transmittance: PC endurance plate has the light transmittance of more than 85% of the glass.

weathering: general PC board exposed outdoors for a long time, easy cause yellowing by ultraviolet radiation and surface degradation. Plate surface must be accompanied by a layer of UV resistant layer, even if long exposure outside, its optical and mechanical properties are no change.

sound insulation performance

PC sound insulation effect is higher than glass 3 - endurance plate 4 db, is the material of highway noise barrier.

chemical resistance

polycarbonate at room temperature to weak acid, weak alkali and alcohol resistance performance is good, but the cavity soda acid, benzene, chlorinated hydrocarbons and esters resistance performance is a bit poor, prone to dissolve, swelling or breakdown phenomenon. Because of its chemical resistance with temperature of internal residual stress and exposure duration, so should pay special attention to before use. Light weight

under the same thickness and area of PC endurance plate weight was only about half of the glass, so can save the handling and construction difficulty and the freight.

are important in ensuring lexan sheet manufacturers, and the machine is utilised by everyone from makrolon suppliers to lexan sheet manufacturers.
