Calcium Stearate
Calcium Stearate
What is calcium stearate?
Calcium stearate is the metallic soap substances that is obtained from the action between Stearic Acid and Calcium Hydroxide. The chemical formulation is Ca(C₁₈H₃₅O₂)₂
Calcium Stearate is a white powder, water-insoluble, and non-moisture-absorbing and widely used.
👉 PVC (PVC Lubricant)
👉 Plastic Additive
particularly in the PVC Particularly in PVC (Polyvinyl Chloride). in both Rigid PVC and semi-rigid PVC
🌟The key feature of Calcium Stearate
✅ PVC (External Lubricant)
Calcium stearate is an External lubricant that helps reduce the friction between PVC and the metal of the machinery.
Reduce the issue of PVC mold stuck,Burn, and the machine wear and tear
✅ Enhancing the potential of PVC manufacturing
Helping in the PVC injection, extrusion, and compression molding flow
Perfect for the industry that wants to Waste reduction and enhancing the power of manufacturing.
✅ Non-moisture absorbing and water insoluble
Calcium stearate is a highly stable
Perfect for the uses of industry environments and long-lasting storage.
✅ Well mixed with Stabilizer PVC
Can be combined with
-
Calcium Zinc Stabilizer
-
Barium Zinc Stabilizer
For enhancing the effectiveness of the overall PVC stability system.
✅ No effect on the color and shine
Colorless, Odorless
Perfect for the work that was required Smoothness, shining, and stable quality
🏭 The usage of Calcium Stearate in the PVC industry
Calcium stearate in a PVC is widely used in these industries include:
• PVC (PVC Film / Sheet)
Making the film smooth and slippery and prevents it from sticking to the roller, while also allowing for good thickness control
• PVC (PVC Pipe & PVC Profile)
Reduce the cause of mold sticking, giving a smooth surface and good shape. Perfect for construction and industrial use.
• PVC (PVC Wire & Cable)
Helping the extrusion consistently reduces the friction, and it extends the lifespan of the insulation.
• The general PVC shaped
Perfect for the industry that wants to getting a high-quality of lubricant

💬 The frequency of asking question about Calcium Stearate (FAQ)
Q1: What is Calcium Stearate? What was it made for?
A: Calcium stearate is a PVC lubricant and plastic additive, helping prevent the mold from sticking, building the surface quality, and improving the manufacturing process.
Q2: How is calcium stearate different from barium stearate?
A: Calcium stearate is the leading of External Lubricant.
But the Barium stearate is leading of the heat stability and Internal Lubricant.
Q3: What type of PVC is the calcium stearate used in?
A: Used for hard PVC, semi-hard PVC, and general-shaped PVC.
Q3: Is calcium stearate safe?
A: It's safe for industry use; keep away from direct inhalation and use the PPE following the standard rule.
Q5: How to store it?
A: Keep in a dry, cool, tightly sealed place and keep away from moisture and the sun, not more than 40 degrees.
