Structural characteristics and action mechanism of plastic lubricant silicone powder:
Silicone powder not only maintains the lubricating properties of EBS, but also has a polar group structure that can combine with some polar groups on the surface of glass fiber and inorganic filler. In glass fiber reinforced or inorganic filled PA6, PA66, PBT and other composite systems.
BZSP001 silicone powder forms similar anchoring nodes between glass fiber, inorganic filler and matrix resin. It improves the bonding state between glass fiber, inorganic filler and matrix resin. And then improves the dispersibility of glass fiber and inorganic filler in matrix resin. At the same time, BZSP001 silicone powder has lubricating properties, improves the processing fluidity of composite materials, and improves the surface finish of composite materials.
Uses of BZSP001 silicone powder in engineering plastics:
As mentioned above, BZSP001 is a silicone powder with excellent heat resistance, suitable for modification and processing of engineering plastics such as PA, PBT, PET, PP, PC, etc. It has the following functions in modified engineering plastics:
1. Improve the adhesion and dispersion of glass fiber and matrix resin, and effectively prevent the exposure of glass fiber.
2. Improve the uniform dispersion of flame retardant in matrix resin.
3. Improve the dispersion state of inorganic filler or pigment in matrix resin.
4. Improve the fluidity of composite materials and reduce mechanical wear.
5. Improve the surface finish of products.
Our company has developed BZSP001 series products according to the characteristics of resin. The main uses are as follows:
1. Used for glass fiber reinforcement PA6, PA66, PA46 to improve glass fiber dispersion and product surface finish.
2. Used for flame retardant reinforcement PA6, PA66, and improve product surface finish.
3. Used for flame retardant reinforcement PBT, PET, and improve product surface finish.
4. Used in flame retardant PC, PC/ABS system, improve the dispersibility and processing fluidity of flame retardant.
Many manufacturers will encounter the problem of PET surface slippage, and then solving this problem is actually very simple. Just choose the right lubricant and use the right amount of addition to effectively improve it.
The general low-grade lubricant is not ideal, because PET has excellent heat resistance, cold resistance, good chemical resistance and oil resistance. When improving the surface slippage, try to use high-molecular plastic lubricants. When using low-molecular lubricants, precipitation and migration are prone to occur. When choosing lubricants, try to choose ultra-high molecular weight plastic high-efficiency lubricants without organic carriers.
Ultra-high molecular weight plastic high-efficiency lubricants without organic carriers have a relatively good effect in use, but the price will be relatively higher than other low-molecular lubricants. Manufacturers should also choose according to their own costs. Plastic production and supply PET surface slip agent manufacturers, provide free sample debugging, and professional technical personnel guidance.
