Product Name: Pentaerythritol stearate
English alias: Pentaerythritol steam; Pentaerythrityl tetrastearate； PETS
CAS number: 115-83-3
Molecular formula: C77H152O8 (main component, may exist in different composition forms such as C37H72O5, C55H108O6 due to different degrees of esterification)
Appearance: White to slightly yellow powder, granules or waxy solid, with a fine texture at room temperature and no obvious odor
Conventional packaging: 20kg/bag
Pentaerythritol stearate is a polyol ester compound formed by the esterification reaction of pentaerythritol and stearic acid. It belongs to non-ionic surfactants and polymer material additives. Its molecular structure contains multiple long-chain alkyl and hydroxyl groups, exhibiting excellent lubricity, compatibility, and stability, and demonstrating outstanding performance in multiple fields.

1. Plastic industry: As an internal and external lubricant for resins such as polyvinyl chloride (PVC), polypropylene (PP), and polyethylene (PE), it can effectively improve the flowability of resin melts, reduce processing equipment wear, and enhance the surface smoothness of products.
2. 2. Coatings and Ink Industry: Used as plasticizers and leveling agents for film-forming substances such as nitrocellulose and ethylcellulose, it can improve the adhesion, glossiness, and water resistance of coatings/inks, reduce film cracking and wrinkling.
3. Cosmetics and personal care: As an emulsifier, emollient and consistency regulator, it is added to face cream, lotion, lipstick, hand cream and other products.
4. Metal processing industry: lubricants used for processes such as aluminum foil rolling and metal wire stretching.
5. Resin processing industry: As a release agent and lubricant for extruded, injection molded, and rolled products such as polystyrene (PS) and ABS resin.
Pentaerythritol stearate is a low toxicity substance that has no significant irritation or sensitization to human skin at conventional concentrations in cosmetics, food contact materials (grades that meet relevant standards), and other fields. The risk of absorption through the skin is extremely low.
Store in a cool, dry, and well ventilated warehouse, avoiding direct sunlight, rain, and high temperature environments
relative humidity < 60%
20kg/bag, 25kg/barrel: can be transported by ordinary trucks, with a stacking height of no more than 8 layers to prevent damage to the bottom packaging under pressure
