Nano-Calcium Product Description:
Highly active nano calcium powder is a functional filler specially developed for PVC products. Through nano-scale surface modification technology, it significantly improves the mechanical properties, processing stability and surface finish of PVC products. This product complies with international environmental protection standards such as RoHS and REACH. It is suitable for hard/soft PVC profiles, pipes, cables, films and other diverse scenarios. It helps customers reduce production costs by 10%-30%, while maintaining excellent product quality, and is an alternative to traditional fillers. The preferred solution.
Nano-Calcium Features:
Ultra-high activity and strong compatibility
Using exclusive organic-inorganic composite modification technology, the binding force between the calcium powder surface and PVC resin is increased by 50%, eliminating "powder agglomeration", and ensuring excellent tensile strength and impact resistance under high filling (addition amount can reach 40%-60%).
Precise particle size control improves surface texture
Provide multiple specifications from 800 mesh to 5000 mesh (support customization), and the D97 particle size distribution is ≤2μm, which significantly improves the surface smoothness and gloss uniformity of PVC products and reduces subsequent spraying costs.
Environmental protection and energy conservation, double effects in one
It is produced through a heavy-metal-free process and complies with EU environmental protection directives; the heat stabilizer has excellent adsorption properties, which can reduce the amount of stabilizer used in PVC processing by 15%, and reduce the overall cost of customers.
Dynamic thermal stability technology
The unique coating process ensures that calcium powder does not decompose or yellowing during high-temperature extrusion (180-220℃), extending the outdoor service life of PVC products.
