Pentaerythritol Stearate Features

  1. Pentaerythritol Stearate has good thermal stability and low volatility at high temperatures, good demoulding, and flow properties, excellent nucleation for partially crystalline plastics, and can be used in transparent products.
  2. It is beneficial to improve the speed of injection and feeding so that the product can obtain a smooth surface and high finish.
  3. Can maintain product transparency and color stability.
  4. As an anti-blocking agent, it is applied to biaxially stretched polyester film to reduce the friction between the film and the film and improve the anti-blocking property of the film.
  5. As a plasticizer, it plays a plasticizing and lubricating role in the rubber mastication process.
  6. As a breathable emollient, it can be used in skincare products.

Pentaerythritol Stearate application

  1. For polycarbonate and alloys, nylon (PA66, PA6), ABS, polyphenylene oxide (PPO), polyphenylene sulfide (PPS) internal and external lubricants and release agents;
  2. Lubricant and dispersant for thermoplastic polyester (PBT, PET);
  3. Lubricants and dispersants for other thermoplastic engineering plastics such as PA, POM, PP, ABS, PVC, HIPS, and PE;
  4. Antistatic agent, lubricant, dispersant, and antifogging agent for polypropylene (PP) and polyethylene (PE);
  5. Antistatic agent and antifogging agent for polystyrene (PS);
  6. Stabilizer, antistatic agent, lubricant, and antifogging agent for polyvinyl chloride (PVC);
  7. Slippery agent and antifogging agent for polyurethane (PU);
  8. Lubricant for thermoset plastics.

(FDA approved, allowed to be used in food packaging materials).

Recommended dosage

The additional amount of the inner and outer lubricants is usually between 0.2 and 1.0%, and the manufacturer adjusts the appropriate amount according to the specific situation.

Product packaging and storage

Packed in 25kg plastic woven bag, transportation and storage must be moisture-proof, sun-proof, and stain-proof.
