Synergistic application of different lubricants
Using calcium stearate alone in the formula can accelerate plasticization, increase melt viscosity, increase torque, and have a certain release effect, while using polyethylene wax alone can delay plasticization and reduce torque. When calcium stearate and polyethylene wax are mixed and used in...Read more -
The influence of various lubricants on the speed of PVC plasticization
Lubricants generally have the characteristics of internal lubrication and external lubrication at the same time, and cannot absolutely have a single performance. From the use effect, the greater the polarity, the better the compatibility with PVC, the more obvious the effect of increasing the f...Read more -

How to control the rate of plasticization
The plasticizing rate is the plasticizing time, and a reasonable lubricating system is an effective method commonly used to control the resin plasticizing rate. This is also an important reason why lubricants must be used for high- temperature easily decomposable resins. It is also an important...Read more -
The principle of anti-settling effect of polyamide wax
Polyamide wax contains abundant hydroxyl and amide groups, which can form strong hydrogen bond chemical forces and form a network structure, thereby increasing the viscosity of the system to achieve anti-settling and anti- sagging effects. ...Read more -
Application of grafted polyethylene wax in plastic filling system
Grafted polyethylene wax is an excellent long-chain coupling agent due to its structural characteristics. The low molecular weight polyethylene part of the grafted wax has good compatibility with the resin and can form intermolecular entanglements. The group and the filler form a complex bond...Read more -
