Key features

Superior Release Performance # Zinc stearate is the most effective metal stearate release agent ; low surface energy prevents rubber, PU, and plastic from sticking to molds

Highly Hydrophobic # Water contact angle >100 degree; repels moisture better than calcium stearate, ideal for waterproofing and anti-caking

Polyolefin Clarifying Agent # As nucleating agent in PP or PE, increases transparency and shortens cycle time ;replaces sorbitol clarifiers at lower cost

Low Dosage External Lubricant # Effective PVC external lubricant at just 0.1 to 0.5 phr, improves surface gloss without plate-out

Heat Stable to 200 degree # Stable during normal PVC/rubber processing; no decomposition or yellowing at typical extrusion temps

Vulcanization Activator # Activates thiuram/sulfide accelerators in rubber, improving cure rate and crosslink density

Free Fatty Acid no more than 0.5% # Low free acid prevents corrosion of equipment and degradation of sensitive polymers

Product Q&A

Q:Are you a trading company or manufactuer?

We are a manufactuer with over 20 years of experience.

Q:What is zinc stearate and how does it work?

Zinc Stearate is a zinc salt of stearic acid, produced as a light fluffy white powder. Among all metal stearates, it has the lowest surface energy, making it the most effective mold release agent. It works by forming a thin hydrophobic lubricating layer between the molten polymer/rubber and the mold surface, preventing adhesion. It also acts as an external lubricant, vulcanization activator, and nucleating agent in polyolefins. Our zinc stearate is available.

Q:Which industries and applications use zinc stearate?

Widely used across six major fields: (1) Rubber : release agent and vulcanization activator for tires, seals, molded goods (1to 5 phr); (2) PVC : external lubricant and heat stabilizer synergist, improves gloss (0.1 to0.5 phr); (3) Polyolefins : nucleating/clarifying agent in PP and PE for transparent parts (0.1to 0.3%); (4) Powder Coatings :sanding and matting agent;

Q:What is the recommended dosage in different applications?

Rubber (release + activation): 1to 5 phr; PVC external lubricant: 0.1to 0.5 phr (combine with internal lubricant for balance); PP/PE nucleating agent: 0.1to 0.3% by resin weight; Powder coatings: 0.5to 2.0% for sanding/matting; Cosmetics: per formulation (typically 2 to15%). Overdose in PVC may cause plate out or blooming;our technical team can optimize your ratio.

Q:What is the packaging and shipping method?

Standard packaging: 20 kg net weight in kraft paper bags with PE inner liner (also available in 25 kg bags). Palletized packing: 40 bags per pallet (800 kg), stretch wrapped. 20 ft FCL loads approximately 16 MT (palletized). Shipping terms: FOB Shanghai . Lead time: 7 to 15 days after order confirmation.
