Polyvinyl chloride (
PVC plastic)
Formula of each component has a certain relationship between each other, not isolated to matching.
Changshu below smooth talk about PVC plastic different profile formula of plastic material factory.
PVC plastic different profile when choosing auxiliaries, should fully consider various aspects factors. Considering the physical property indexes are not independent factors change, often influence each other, restrict each other. Such as in order to improve the impact resistance of PVC plastic different profile, add rubber or elastic polymer are effective, but will cause extrusion mold modulus and rigidity and heat resistance. And as to improve the heat resistance of PVC plastic different profile, it can improve the glass transition temperature of PVC chloride Tg. , but also increase melting temperature Tm, so as to make the processability of PVC resin and liquidity significantly worse. Evaluation formula pros should be mainly PVC plastic mechanical products property index, physical property indexes and, of course, depends on the plastic mechanical products using different environment and conditions, for example, according to the window frame used in indoor and outdoor environment, color, size of the physical property indexes of different requirements and differences. Rigid PVC resin compared with other thermoplastic resin, rigid PVC resin property indexes and processability by formula of additives, mixing technology and a greater influence on the forming conditions, the formula of hard PVC plastic different profile is a very complex and important work. Rigid PVC plastic different profile formula made from PVC resin, stabilizing agent, modification agent, lubricant, filler, coloring agent and so on more than 10 kinds of additives made from mixing, choose the type and quantity of additives, can be matched into different performance of PVC plastic different profile formula, thus the complexity of the PVC plastic different profile formula.
