As a professional TPE material sales specialist, we often encounter customer feedback that TPE packaging molding viscosity is not good, and it will open immediately. Then this problem is the problem of TPE or the molding process. So today we have to solve this problem. After all, what factors affect the viscosity of TPE packaging, I will follow my footsteps to see ... TPE packaging, as its name suggests, is to glue TPE soft adhesive material to other materials. The general processing methods used are two-color injection molding machines for one molding, or general injection molding machines for the use of plastic mold, divided into two injection molding. Factors that affect the adhesion between the secondary injection TPE material and the matrix(PP, ABS, PC, PA):
1) Matrix type-additive(glass fiber, mineral filling, heat stabilized treatment, lubricating oil);
2) Type of color base carrier;
3) Water content in the secondary injection molding layer and Matrix;
4) quality of recycled materials and proportion of additions;
5) cleanliness, preparation and preheating of the matrix;
6) processing conditions(melt temperature, pressure, injection speed, cooling time);
7) Design of workpieces and molds(especially truncated design).
