  pc, the residual bisphenol a, the higher the temperature,the faster speed of release. therefore, should not be "pc waterbottle filled with hot water. if your kettle number is 07, thefollowing methods can reduce the risk: do not heat when using, donot direct in the sun. don’t use a dishwasher&a bowl machine toclean the kettle. di before use, rinse with baking soda&warmwater&dry naturally at room temperature. if the container hasany 

falls/breakage, it is recommended not to use it because thesurface of the plastic is prone to contain bacteria if there arefine pits. avoid repeated use of aged plastic appliances. a cup oflow is 7 cups are made of polycarbonate used, i.e., pc, used tocall a bisphenol a material in the production process of rawmaterials in "pc, pc" in the material will be more/less existbisphenol a monomer, the higher the temperature, the faster speedof release. pc "pc" -1750, pc "pc" -1100, pc "pc" -1150, pc "pc"-1220, pc "pc" -1070, pc "pc" -1070u, pc "pc" 3025ir, 3022, pc / /pc / / -1220u.

  the chemical&physical properties of pa6 are similarto those of pa66, however, it has a lower melting point&a widerange of process temperatures. its impact resistance&solubilityare better than pa66, but its moisture absorption is stronger.because many of the quality characteristics of plastic parts aresubject to moisture absorption, so the use of pa6 design productsshould take full account of this. in order to improve themechanical properties of pa6, a variety of modifiers are oftenadded.
