High activity and strong compatibility
Through the unique organic-inorganic composite modification technology, the binding force between the surface of nano-calcium carbonate powder and PVC resin is significantly improved, effectively preventing filler agglomeration and ensuring excellent mechanical properties, such as tensile strength, impact toughness and size stability, under high addition amounts (40%-60%).
Precise particle size control improves surface texture
Available in multiple specifications from 800 mesh to 5000 mesh and can be customized. The D97 particle size distribution is ≤2μm. Nano-calcium carbonate significantly improves the smoothness and gloss uniformity of the surface of PVC products, reduces subsequent spraying costs, and is suitable for high-end products with strict appearance requirements.
Environmental protection and energy conservation, double effects in one
No heavy metals are added in the production process and comply with international environmental protection standards such as RoHS and REACH. Nano-calcium carbonate powder has excellent adsorption effect on heat stabilizers, which can reduce the amount of stabilizers in PVC processing by about 15%, reducing costs and enhancing environmental protection.
Dynamic thermal stabilization technology
The special coating process ensures that the nano calcium carbonate powder does not decompose or yellowing during high temperature processing (180-220℃), extending the service life of PVC products in outdoor environments, and is especially suitable for high weather resistance requirements such as door and window profiles and outdoor pipes.
