Introduction and properties of PVC stabilizer

Sources generalized chemical stabilizer is very extensive, mainly based formulation designed to designers, the flexibility to use any chemicals to achieve a stable product quality purposes. Narrowly speaking, mainly refers to maintain high polymer plastics, rubber, synthetic fibers, such as PVC stabilizer
  and prevent its decomposition, the aging of reagents. PVC stabilizer for pipe can increase the solution, gel, solid, stable mixture of chemicals called stabilizers. PVC stabilizer for pipe can slow down the reaction, to maintain chemical balance, reduce surface tension, to prevent the light, thermal decomposition or oxidation decomposition effect.Composite Heat Stabilizer conducive scale production, for the development of lead salt heat stabilizer provides a new direction. Auxiliary heat stabilizer itself does not have heat stability, and only used in combination with the primary PVC stabilizer
 , heat stabilizing effect will be generated, and to promote the primary stabilizing effect of the stabilizer. Auxiliary heat PVC stabilizer for pipe generally does not contain metal, also known as non-metal heat stabilizers. Lead salt stabilizer low price, good thermal stability, has been widely used, the composite heat stabilizer of the various components can be adequately mixed in the course of production, with a significant improvement in mixing the resin dispersion uniformity. Simple supply and reserve the materials is conducive to production and quality management.

WSD PVC stabilizer Introduction

Solution can increase, colloidal solids, chemical stability of the mixture are called stabilizers. It can slow down the reaction, to maintain chemical balance, reduce surface tension, to prevent the light, thermal decomposition or oxidation decomposition effect. Sources PVC heat stabilizer chemical stabilizer is very extensive, mainly based formulation designed to designers, the flexibility to use any chemicals to achieve a stable product quality purposes. Narrowly speaking, mainly refers to maintain high polymer plastics, rubber, synthetic fibers, such as stability and prevent its decomposition, the aging of reagents. Auxiliary heat stabilizer itself does not have heat stability, and only used in combination with the primary stabilizer, heat stabilizing PVC stabilizer for profile will be generated, and to promote the primary stabilizing effect of the stabilizer. Secondary thermal stabilizers generally do not contain metal, which is also called a non-metallic heat stabilizers. Liquid stabilizer more popular in the country are: liquid barium zinc stabilizer, liquid calcium zinc stabilizers, liquid barium cadmium zinc stabilizers, liquid barium cadmium stabilizers, liquid potassium zinc catalyst foam stabilizer.

WSD PVC stabilizer one pack stabilizer PVC Heat stabilizer Introduction and Safety

  WSD PVC stabilizer is one important class of plastics processing aids, the birth and development of a thermal stabilizer synchronization with PVC resin is mainly used for the processing of PVC resin, heat stabilizer and so the PVC resin, the ratio of hard and soft PVC products are a close relationship. Since the thermal energy, such as PVC stabilizer for profile  fillers, and other compatible polymers and many other materials, which is considered one of the most common polymers. Its main drawback is the differential thermal stability.
  The use of additives to change the polyvinyl chloride (PVC) and the operating characteristics of the physical appearance, but can not prevent the decomposition of the polymer. Although in the physical and chemical factors of the polymer material will always gradually destroyed, but the PVC stabilizer is called a class of substances can be effectively prevented, substantially reduced or even stop the degradation of the material. Security issues heat stabilizers have more and more people's attention. . Safety PVC stabilizers should consider three aspects, namely the safety of the use of raw materials processing, the second is the user's security, the third is the safety of waste on the environment. Processors security PVC heat stabilizer calcium stearate  measures can be liquefied by stabilizers, cream-based, granular, etc. to be addressed. For the user's safety, the molecular weight of the stabilizer may be prepared in a reactive stabilizer or to improve its resistance to pulling, but taking into account the effect of stabilizing the chemical reaction at the molecular level, the above method is not the most appropriate method, the most good way to still use high security stabilizers. In the choice of the stabilizer, the stabilization process must also be considered in the resin with a stabilizer, or stabilizing agents react with each other the resulting chemical safety.
