As a leading innovator in polymer additives, Qingdao Sainuo Group. proudly introduces PETS (Pentaerythritol Tetrastearate), a high-performance lubricant designed to revolutionize your polymer processing. With its exceptional thermal stability, versatility, and eco-friendly profile, PETS is the go-to solution for industries ranging from PVC manufacturing to advanced engineering plastics.

What Makes PETS Stand Out?

PETS is a non-ionic, multifunctional ester-based lubricant synthesized from pentaerythritol and stearic acid. Its unique molecular structure ensures outstanding performance in high-temperature environments, making it ideal for demanding applications. Key advantages include:

1. Thermal Stability: PETS retains structural integrity up to 350°C with minimal weight loss, ensuring reliability in high-heat processes like extrusion and injection molding.

2. Dual Lubrication: Combines internal and external lubrication, reducing friction between polymer chains and equipment surfaces while enhancing flow properties.

3. Transparency & Surface Finish: Unlike traditional lubricants, PETS minimizes haze and improves clarity in transparent products like PC and PET.

4. Low Volatility: Minimal emissions during processing, promoting workplace safety and environmental compliance.

5. FDA Compliance: Approved for food-contact applications, ensuring safety in packaging and consumer goods.

Applications Across Industries

1. PVC Processing

PETS excels as a stabilizer and lubricant for rigid and flexible PVC. Studies by Qingdao University of Science and Technology confirm that adding 1–2 phr PETS in injection molding improves impact strength by 23.5% while maintaining thermal stability. For extrusion, 1 phr optimizes surface smoothness and reduces die buildup.

2. Engineering Plastics

• PC (Polycarbonate): PETS enhances melt flow rate by 30% at 0.3–0.5 phr, reducing processing energy and improving mold release.

• PA, PBT, PET: Acts as a nucleating agent for crystalline plastics, accelerating cycle times and boosting mechanical properties.

• PPO, PPS: Ensures consistent flow in high-temperature resins, ideal for automotive and electronics.

3. Rubber & Specialty Lubricants

• Reduces roll sticking and improves dispersion during rubber compounding.

• Serves as a metalworking lubricant for cutting and sheet rolling, extending tool life.

Why Choose Sainuo’s PETS?

1. Cost-Effective: Outperforms imported alternatives at competitive pricing.

2. Custom Solutions: Tailored formulations (PETS-A, PETS-B, etc.) to meet specific processing needs.

3. Technical Support: Backed by R&D partnerships with leading universities and 20+ years of industry expertise.
