Plastic pc is food grade.
Plastic pc is food grade. pc plastic can be used to make sports cups jugs, bottles, etc., widely used in the production of plastic containers, is a safe material. Safety hazards: PC in the residual bisphenol A (harmful substances), the higher the temperature, the release of more and faster. Therefore, PC water bottles should not be used to hold hot water, so as not to increase the speed and concentration of BPA release.
PC's biggest advantages are good strength and toughness and good-looking, with a certain degree of flame retardancy. Engineering plastics strength, there is nothing to say, and because of poor crystallinity, so the transparency of the PC is very high, about 89-90%, you can refer to the best transmittance of PMMA is 92-93%, and because PMMA is not scratch-resistant, so a lot of optics and strength are required in the field of the need for PC on the scene.
