Product Overview:

Pentaerythritol Tetraisostearate (PETS) is a high-performance tetraester of pentaerythritol and isostearic acid. It offers excellent thermal stability, lubricity, and plasticizing properties, making it an ideal multifunctional additive for PVC, rubber, engineering plastics, and cosmetic formulations. As a non-volatile, non-toxic ester with superior hydrolysis resistance, PETS is widely preferred in demanding industrial applications where conventional plasticizers fail to perform.

Key Features:

✓ Outstanding thermal stability – stable up to 300°C, suitable for high-temperature processing

✓ Excellent internal/external lubricity – reduces torque and improves melt flow during processing

✓ Superior plasticizing efficiency – low migration, low volatility, long-lasting flexibility

✓ Hydrolysis-resistant – performs well in humid environments

✓ FDA-compliant cosmetic grade available – suitable for skincare and color cosmetic formulations

✓ REACH registered – compliant with EU chemical regulations

Applications:

• PVC Processing – Acts as a high-temperature lubricant and plasticizer in PVC extrusion, calendering, and injection molding; improves surface finish and reduces plate-out

• Rubber Industry – Used as a processing aid and internal lubricant in tire and rubber compound manufacturing; enhances dispersion of fillers and improves mold release

• Engineering Plastics – Functions as a lubricating additive in polycarbonate (PC), PET, and nylon processing; improves melt flow and dimensional stability

• Cosmetics & Personal Care – Employed in skincare creams, lipsticks, and color cosmetics as an emollient, pigment dispersant, and film-forming agent; imparts smooth, non-greasy feel

• Lubricating Oils & Greases – Used as a base stock component and anti-wear additive in high-performance industrial lubricants

• Coatings & Inks – Acts as a flow and leveling agent in industrial coating systems
