the commonly used blister temperature of pet and PVC sheet?

1. PVC: due to the poor thermal stability of PVC, long-term heating will lead to decomposition, release HCl gas, make PVC discoloration, so its application range is narrow, the use temperature is generally between 15-55 degrees.
2. Pet: the thermal deformation temperature of pet is 80-82 degrees, and the color and non transparent sheet are added with color masterbatch and additives, which will affect the thermal deformation temperature of sheet, which can be adjusted according to the specific situation.
[blister forming technology] that is, the thermoforming processing technology of plastic sheet (board), is one of the secondary processing industrial technologies of plastics. It is different from injection molding, extrusion and other one-time processing processes. It is not aimed at the heating molding of plastic resin or particles or the continuous molding of the same cross section of the same die. It is not to use machine tools, cutting tools and other mechanical processing means to cut a part of plastic materials to obtain the required shape and size. It is aimed at the plastic sheet (plate) material, to heat it, to use the mold, to be true Air or pressure can deform the sheet (plate) to achieve the required shape and size, supplemented by supporting procedures, so as to achieve the application purpose.
The equipment includes clamping system, heating system, vacuum and compressed air system and forming mould.
