High Thermal Stability # Melting point 200 to 225 degree ; highest among common stearates, ideal for high temperature PVC processing without decomposition
Excellent for Transparent PVC # Barium stearate does not impair clarity, making it the classic choice for transparent PVC sheets, films, and bottles
Dual Function: Stabilize + Lubricate # Acts as both heat stabilizer component and external lubricant in one additive, simplifying formulations
Synergistic with Zn/Ca # Pairs with zinc stearate (Ba-Zn system) or calcium stearate for balanced stabilization and lubrication
Good Heat Aging # Slows PVC thermal degradation at processing temps 180 to 220 degree, extends product service life
Paint & Varnish Matting # Effective flatting/sanding agent in coatings for uniform low-gloss finish
Consistent Ba Content 0.5% # Tight barium control ensures reproducible stabilization performance batch to batch

Product Q&A
Q:Are you a trading company or manufactuer?
A:
We are a manufactuer with over 20 years of experience.
Q:What is barium stearate and how does it work?
A:
Barium Stearate is a white powder made by neutralizing stearic acid with barium compounds. With a melting point of 200 to 225degree ;the highest among common metal stearates . it offers excellent thermal stability. In PVC it works as a heat stabilizer component and external lubricant: it absorbs HCl released during thermal degradation and forms a lubricating film on the metal surface, preventing sticking and discoloration. It is especially valued for transparent PVC because
Q:Which industries and applications use barium stearate?
A:
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?
A:
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?
A:
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.
