[Bite Chemical] The role of erucamide in TPE and its addition suggestions

Erucamide appears as white particles or powder. Soluble in organic solvents such as ethanol and ether. The production method is obtained by ammoniation and dehydration of erucic acid and ammonia under the action of a catalyst. Erucamide, as an important derivative of erucic acid, is an excellent fine chemical product with a wide range of applications. Because it has a high melting point and good thermal stability (stable at 273°C), it is mainly used as an anti-sticking agent and slip agent for various plastics and resins, and an excellent lubricant and antistatic agent for extruded films. . Its main uses are smooth, anti-stick and bright.

The role and addition suggestions of erucamide in TPE are as follows:

It is understood that erucamide can be used as a release agent for thermoplastic elastomer TPE agents and surface smoothing and brightening agents.

Generally, adding 0.05% erucamide to low-hardness thermoplastic elastomer TPE-S will make the appearance smoother, but be careful not to add too much, as it will have a slippery feeling. If you want to prevent low The hardness of TPE-S is adherent. You can increase the amount slightly and use it with silicone lubricant for better results. (In medium-to-high hardness thermoplastic elastomer TPE-S, for specifications with higher oil-filled content that require aging resistance, it is recommended to add erucamide.)

To reduce the friction of thermoplastic elastomers for a long time Coefficient, the addition amount is about 1%, and it is combined with silicone, fluorine additives, etc.

In thermoplastic rubber TPV, it is recommended to use erucamide due to the high processing temperature, and the addition amount is about 0.05%.
