Premium Products Deserve Top Priority!
You may not have noticed that municipal pipes crisscrossing urban underground networks, sturdy shopping bags in supermarkets, high-efficiency self-leveling floors at construction sites, and even express delivery cartons all adopt the same eco-friendly new material.
Developed through high-value utilization of by-products from phosphorus chemical industry, Recrystalized calcium gypsum stands out with four core merits: high transparency, superior strength, stable performance and zero precipitation. It can replace traditional fillers to cut costs, upgrade product performance and feature outstanding environmental friendliness. This exclusive patented material is independently developed by Guizhou Phosphate Chemical Group.
Four Core Advantages
✅ High Transparency
When applied to film and bags, anhydrous gypsum-based Recrystalized calcium gypsum delivers higher transparency than calcium carbonate and talc powder.
✅ Zero Precipitation
It boasts similar transparency to sodium sulfate filler without the defect of powder precipitation, ensuring stable finished product quality.
✅ Excellent Strength
Compared with traditional calcium carbonate fillers, it greatly improves tensile property and hardness of end products.
✅ Stable Performance
Matched with mature processing equipment, it maintains steady physical indicators of finished products in mass production.
What Exactly Is Recrystalized calcium gypsum?
Recrystalized calcium gypsum is high-quality modified anhydrous gypsum refined from calcium sulfate dihydrate, a by-product generated in phosphoric acid production. It undergoes crystal transformation, drying, depolymerization, activation and air classification.
In short, it realizes technological upgrading for high-value reutilization of industrial by-products. With exclusive technical reconstruction, industrial waste gypsum is restructured into functional fillers featuring high purity, high whiteness and uniform particle size, perfectly conforming to circular economy and green manufacturing trends.
Core Strengths Empowering Downstream Industries
🔹 Superior Performance & Better Filling Effect
It significantly enhances mechanical strength and durability of plastic products, optimizes film transparency and brightens product colors while reducing pigment dosage.
🔹 Smooth Processing & Higher Production Efficiency
Low oil absorption value and uniform particle size ensure excellent dispersibility and fluidity, boosting production efficiency, stabilizing yield rate and lowering production loss.
🔹 Cost-effective & Economical
It can fully replace ground calcium carbonate, light calcium, talc powder, barium sulfate and other conventional fillers to slash raw material costs, and cut usage of auxiliary additives for overall expense optimization.
🔹 Eco-friendly & Aligned with Dual-carbon Goals
Derived from comprehensive utilization of industrial by-products, it complies with waste-free city construction and circular economy policies, helping enterprises highlight green development credentials and fulfill social responsibilities.
