Product Q&A
Q:What is Calcium Stearate used for?
A:
Calcium Stearate is widely used as a lubricant and release agent in plastics, rubber, and powder coatings. It helps improve processing flow and prevents materials from sticking to equipment. It also acts as a water repellent in building materials and an anti-caking agent in certain powders.
Q:Is Calcium Stearate safe for industrial use?
A:
Yes, Calcium Stearate is considered safe for industrial applications when handled properly. It is a stable, non-toxic compound. However, we recommend using appropriate protective equipment such as gloves and dust masks during handling to avoid prolonged skin contact or inhalation of dust particles.
Q:What is the difference between Calcium Stearate and Zinc Stearate?
A:
Calcium Stearate provides better heat stability and works well as a lubricant, while Zinc Stearate offers higher transparency and is preferred in clear PVC products. The choice depends on your specific application, such as rigid or flexible PVC, and the required final product appearance.
Q:How should Calcium Stearate be stored?
A:
Calcium Stearate should be stored in a cool, dry, and well-ventilated area. Keep the bags sealed to prevent moisture absorption, which can affect its performance. Avoid direct sunlight and high temperatures. Under proper storage conditions, the shelf life is typically 12 months from production date.
Q:What packaging options are available?
A:
Our standard packaging is 25 kg woven bags with inner PE liners. We also offer custom packaging options such as 500 kg or 1000 kg jumbo bags upon request. Please contact us for specific packaging requirements to meet your shipping and handling needs.
