Silicone masterbatch: the solution to internal and external lubrication problems
In the field of plastic processing, the selection of lubricants is crucial for improving production efficiency and product quality. Silicone masterbatch, as a multifunctional lubricant, has attracted widespread attention due to its unique internal and external lubrication characteristics. This article will explore how silicone additives can effectively solve internal and external lubrication problems, and analyze its application advantages in plastic processing.
1. The importance of internal and external lubrication issues
In the process of plastic processing, internal and external lubrication issues directly affect the flowability of materials, the service life of molds, and the quality of the final product. Good internal lubrication can reduce friction between polymer molecules and improve the flowability of materials; Good external lubrication helps to separate materials from processing equipment (such as molds), preventing adhesion and material accumulation.
2. Introduction to Silicone Masterbatch
Silicone masterbatch is a plastic additive containing silicone compounds, which has excellent thermal stability, chemical stability, and lubricity. The main component of silicone masterbatch is silicone oil, which can play the following roles in plastic processing:
-Internal lubrication: reduces friction between polymer molecules and improves material flowability.
-External lubrication: Reduce friction between plastic and processing equipment (especially molds) to prevent adhesion.
3. The internal and external lubrication mechanism of silicone masterbatch
3.1 Internal lubrication function
The silicone oil molecules in silicone additives can penetrate between polymer chains at high temperatures, forming a lubricating film. This layer of film can reduce the friction between polymer molecules, making it easier for the material to flow during processing, thereby improving production efficiency and product quality.
3.2 External lubrication effect
The lubricating film formed by silicone masterbatch on the surface of plastics can also reduce friction between plastics and processing equipment, especially molds. This external lubrication effect helps to facilitate the smooth demolding of materials in the mold, reduce adhesion and material accumulation, and extend the service life of the mold.
4. Application advantages of silicone masterbatch
4.1 Improving Production Efficiency
By improving the flowability of materials and reducing mold adhesion, silicone additives can significantly improve the production efficiency of plastic processing and reduce downtime caused by mold cleaning.
4.2 Improving Product Quality
The internal and external lubrication effect of silicone additives helps to reduce surface defects such as flow marks, weld lines, etc., thereby improving the overall appearance and performance of the product.
4.3 Extending Mold Life
The external lubrication effect of silicone masterbatch can reduce the wear and damage of molds, extend the service life of molds, and reduce production costs.
4.4 Environmentally friendly
Silicone masterbatch usually has good environmental compatibility, does not cause pollution to the environment, and meets the requirements of modern industrial production for environmental protection.
