How to select heat stabilizer in PVC injection molding?
The stability of PVC products will directly affect the processing performance and quality of the products. So how do you focus on the PVC injection molding, the choice of stabilizer? Now PVC heat stabilizer manufacturers explain the question for you.
In PVC products injection molding process, the material passes through the screw shear plasticizing and staying in screw front melt zone, relatively long residence time at high temperature, and because the melt injection at high speed, can produce a large amount of heat, due to the strong shear materials up to a high temperature. Injection formula of thermal stability, therefore, demand higher (torque rheometer at 200 deg.C on the determination of the thermal stability of time to reach 30-40 min) and dosage of heat stabilizer usually forming method of matching more than others.
The stabilizer used in the formulation of rigid polyvinyl chloride injection parts is mainly composed of lead salt thermal stabilizer, organic tin thermal stabilizer, composite calcium zinc thermal stabilizer and rare earth thermal stabilizer. Lead salt thermal stabilizer is widely used because of its high cost performance. But because lead is a toxic heavy metal, it is limited in many areas. For eco-friendly and non-metal toxic, calcium zinc stabilizer take the place of lead salt thermal stabilizer.
