Physical Properties

Strong chemical stability, non-toxic, odorless and non-irritating.

It can be surface modified (such as stearic acid and titanate coupling agent treatment) to enhance the compatibility with organic materials.

Main Application Fields And Functions

1. Functional role of plastic industry：

Filling enhancement: replace part of the resin and reduce production costs.

Improvement of mechanical properties: improve tensile strength, rigidity and dimensional stability (especially suitable for PVC, PP, PE).

Optimization of processing performance: improve melt fluidity and shorten injection cycle. 

Typical application：Hard PVC products: pipes, profiles.

Automotive plastic parts: instrument panels, interior parts (composite with engineering plastics after surface modification).

2. Functional role of rubber industry：

Reinforcement filling: replace some carbon black, reduce costs and improve color (white/light-colored rubber products).

Adjustment of wear resistance and elasticity: improve the tear strength and resilience of rubber products.

Typical application：

Tires: sidewall rubber, inner lining.

Seals and hoses: oil-resistant and aging-resistant rubber products (composite with nitrile rubber). Sole material: improve wear resistance and lightweight.

3. Functional role of coatings and inks：

Whitening and covering: Replace some titanium dioxide.

Rheology control: improve the thixotropic properties of the coating and prevent sedimentation.

Enhanced weather resistance: improve the coating's resistance to chalking and ultraviolet rays.

Functional role：

Whitening and covering: Replace some titanium dioxide.

Rheology control: improve the thixotropic properties of the coating and prevent sedimentation.

Enhanced weather resistance: improve the coating's resistance to chalking and ultraviolet rays. Typical application：

Water-based coatings: building interior and exterior wall coatings.

Industrial anticorrosive coatings: composite with epoxy resin to improve the dispersion of fillers. Printing ink: adjust the viscosity to improve the clarity of printing.

4. Functional role of paper industry：

Packing instead of wood pulp: reduce the amount of fiber and save costs.

Improve paper performance: improve opacity, smoothness and printing suitability.

Environmental protection requirements: adapt to neutral/alkaline papermaking process and reduce acid pollution of wastewater.

5. Medicine and Food

Medical field：

Calcium supplements: excipients for tablets and gel hair (must comply with USP/EP pharmacopoeia standards).

Drug carrier: Sustained-release skeleton material in controlled-release preparations.

Food additives：

Nutritional fortifiers: calcium sources for bread and milk powder (limited use in GB 2760). Anticaking agent: Prevent powdered food from clumping (such as salt and seasonings).

6. Environmentally friendly materials in other emerging fields：

Degradable plastics: PLA/PBAT composite materials are used as fillers to reduce costs and accelerate degradation.

Wastewater treatment: Adsorb heavy metal ions (such as Pb2+, Cd2+) and adjust the pH of wastewater. 

New energy：

Lithium battery diaphragm coating: improve the high temperature resistance of the diaphragm and the wettability of electrolyte. Photovoltaic materials: anti-aging fillers in EVA film.

Building materials innovation：

Lightweight concrete: replace part of the cement and reduce the weight of the building (suitable for assembled buildings).

Environmentally friendly putty powder: replace talcum powder to improve the hardness of the wall.
