What Are Calcium Sulfate Whiskers?
Calcium Sulfate Whiskers are ultra-fine, needle-like crystalline fibers synthesized under controlled hydrothermal conditions. Composed primarily of CaSO₄·2H₂O or CaSO₄·0.5H₂O, these whiskers exhibit exceptional aspect ratios, uniform morphology, and excellent dispersion in polymer matrices—especially rubber.
The keyword Calcium Sulfate Whiskers CaSO₄ for Rubber defines a class of high-performance inorganic fillers that significantly enhance the physical properties of rubber compounds.
Why Use Calcium Sulfate Whiskers CaSO₄ for Rubber?
Integrating Calcium Sulfate Whiskers CaSO₄ for Rubber into your formulation provides a host of mechanical and functional advantages:
🔹 Key Benefits:
Superior Reinforcement – Improves tensile strength and modulus
Thermal Stability – Withstands high processing and service temperatures
Low Shrinkage – Enhances dimensional accuracy in molded products
Good Dispersion – Reduces agglomeration for uniform properties
Cost-Effective Alternative – Replaces expensive materials like aramid fibers or nano-clays
📊 Comparative Performance:
| Property | Without Whiskers | With CaSO₄ Whiskers |
|---|---|---|
| Tensile Strength | Moderate | ↑ 25–35% |
| Compression Set Resistance | Fair | ↑ Significantly |
| Heat Deformation Resistance | Low | ↑ 40–50% |
Applications of Calcium Sulfate Whiskers CaSO₄ for Rubber
