This product is excellent thermal stability of resin products, thermogravimetric analysis results showed that to 400 ℃, began to slow decomposition, with very little volatile, as a lubricant is widely used in various kinds of engineering plastics processing, can prevent the plastic melting body adhesion on mould and equipment, at the same time can make the products in high temperature stripping smoothly, even in the complex structure of the mold can ensure good demoulding, another in the process of feeding, it can prevent the raw material zone melting phenomenon (bridge).

It is helpful to improve the filling speed of injection feeding materials, and make the products get smooth surface and high smoothness.

Excellent nucleation of partially crystallized plastics and can be used in transparent products.


In the process of rubber refining, as lubricant, plasticizer and mold release agent.

-- lubricant, mold release agent, antifogging agent and antistatic agent in PVC, PC, ABS/PC alloy and other materials, adding amount: 0.3-1%

-- used as lubricant, dispersant and mold release agent in PPO, PPS, HIPS and other plastics.

-- on ABS at high temperature vica softening point, the processing fluidity of ABS engineering plastics can be greatly improved with the addition amount of 0.5-2%.

-- it is used as an environment-friendly high temperature anti-adhesion agent on PBT, PET and other bidirectional stretch polyester film, with good thermal stability and minimal volatility. The addition amount is 0.2-1.0%

-- in the processing of modified PA6 and PA66 products, it is used as a high-temperature lubricant with internal and external balance and a glass fiber anti-exposure agent with the addition amount of 0.4-0.6%

- antistatic agent, lubricant, dispersant and antifogging agent in PE and PP.

- in polyurethane (PU) as a slip agent and antifogging agent.

- in the field of cosmetics for skin moistening, lubrication.

-- used as thickening agent in the field of oilfield drilling chemicals.

The additive amount of this product is usually between 0.2 and 1%, and the producer can adjust the usage according to the specific situation.


-- good thermal stability and low volatility at high temperature, good demoulding and flow performance.

Excellent nucleation of partially crystallized plastics and can be used in transparent products.

-- outstanding thermal stability makes it suitable for processing thermoplastic engineering plastics without worrying about degradation.

- can significantly improve transparency and surface finish

Packaging: this product is plastic composite bag with transparent inner plastic bag, net weight is 25kg/ bag.
