Changshu smoothly of brittle plastic products factory about PVC plastic profile of the big four reasons

PVC plastic material in a short span of a few years, no matter from the industry occupies a proportion or from production, PVC plastic material has good prospects for development. The PVC plastic profile is a love-hate relationship, in the process of production of PVC plastic material what is the reason of the brittle? Changshu below smooth crisp da plastic products factory on PVC plastic profile four big reasons.



1, the excessive packing



in the production of PVC plastic profile joined the excess calcium carbonate, the unreasonable packing will greatly reduce the profile of the physical and mechanical properties, material brittle phenomenon.



2, stabilizers, too little or too much



the role of stabilizer is inhibiting degradation, stability agent can affect the impact strength of profiles, more or less stable doses can cause plastic material brittle phenomenon.



3, external lubricant consumption too much



the dosage of lubricant is overmuch, can cause the compact difference between the plastic material, poor plasticizing, resulting in shock resistance is poor, cause plastic material brittle.



4, and other reasons for



hot mix sequence set value and the curing time, temperature, these will have decisive factor on the performance of the plastic material.
