Today, as an old brand of Yonghengsheng plastic machinery manufacturer, let me introduce to you what is the plastic temperature of PET and PVC sheets in general?
The plastic temperature of PET and PVC sheets in general:
1. PVC: Due to the poor thermal stability of PVC, long-term heating will cause decomposition, release HCL gas, and make polyvinyl chloride discolor, so its application range is narrow, and the use temperature is generally between 15 and 55 degrees.
2. PET: The heat distortion temperature of PET is 80~82 degrees. Color masterbatch and additives are added to the color and non-transparent film, which will affect the heat distortion temperature of the sheet, which can be adjusted according to the specific situation.
Blister molding technology: that is, plastic sheet (board) material thermoforming processing technology, which is one of the industrial technologies of plastic secondary processing. It is different from the one-time processing technology such as injection molding and extrusion. It is not heating molding for plastic resin or pellets or continuous molding with the same cross-section through the die; nor is it using machine tools, knives and other mechanical processing methods to cut some plastic materials Next, to obtain the required shape and size, but for the plastic sheet (board) material, heating, using mold, vacuum or pressure to deform the sheet (board) material to achieve the required shape and size, supplemented by supporting procedures to realize the application purpose.
The blister forming equipment includes clamping system, heating system, vacuum and compressed air system and forming mold.
