A Must-See for Cost Reduction & Quality Improvement! What Makes This New Product So Powerful?

    You may not have noticed it yet:
    Municipal pipes running underground, sturdy shopping bags in supermarkets, self-leveling floors on construction sites, even express delivery cartons…
    Behind these seemingly unrelated products lies the same green new material, quietly making its way in.

    It comes from the high-value utilization of phosphorus chemical by-products, and stands out with four core strengths: high transparency, excellent strength, stable performance, no precipitation.

    It not only replaces traditional fillers to lower costs but also improves product performance — with a built-in green environmental advantage.
    It’s called Crystal-Converted Calcium, powered by exclusive technology from Guizhou Phosphate Chemical Group (GPC).

   High transparency
    When used in films and bags, anhydrite / Crystal-Converted Calcium delivers higher transparency than calcium carbonate and talc powder.

   No precipitation
    Its transparency in film products is comparable to sodium sulfate, yet unlike sodium sulfate, it causes no powder precipitation.

    Excellent strength
    Compared with traditional calcium carbonate fillers, downstream products show better tensile properties and hardness.

   Stable performance
    With standard processing equipment, it ensures consistently stable performance in finished products.

   From Industrial By-Product to Functional New Material
    What exactly is Crystal-Converted Calcium?
    Crystal-Converted Calcium is a type of high-purity anhydrite, produced from calcium sulfate dihydrate — a by-product of phosphoric acid production.
    It is refined through a series of processes: crystal structure conversion, drying, depolymerization, activation and air classification.

    In short:
    It is a technological upgrade for the high-value utilization of industrial by-products.
    Gypsum generated from phosphoric acid production is restructured via GPC’s proprietary technology, transforming it into a functional filler with high purity, high whiteness and uniform particle size.
    It fully aligns with the trends of circular economy and green manufacturing.

   Four Core Strengths
    Despite its technical name, every advantage of Crystal-Converted Calcium directly addresses industry pain points:
    ✅ Superior performance — visible filling effect
    When filled into plastic products, it significantly improves mechanical strength and durability.
    In film blowing, it boosts transparency. For colored products, it enhances color vividness and reduces pigment consumption.

    ✅ Smoother processing — maximized production efficiency
    With low oil absorption and uniform particle size, the powder disperses easily and flows excellently during production.
This means higher efficiency, more stable yield, and less waste caused by poor dispersion.

    ✅ Lower cost — outstanding overall cost performance
    It can replace heavy calcium carbonate, light calcium, talc powder, barium sulfate and other traditional fillers, cutting raw material costs.
    Its high performance also reduces the dosage of other additives, further optimizing total production cost.

    ✅ Green & eco-friendly — in line with “Dual Carbon” goals
    Derived from comprehensive utilization of industrial by-products, it supports “Zero-Waste Cities” and circular economy policies.
Using Crystal-Converted Calcium enhances the green attribute of products and boosts corporate social responsibility image.

   Application Scenarios Beyond Imagination
    What makes Crystal-Converted Calcium stand out is its versatility.
    It acts as a functional filler in polymer materials and a cementitious material in the construction sector.

    🔹 Polymer Filling Sector
    After grinding to 800–2000 mesh and surface activation, it is widely used in:
    Pipes: municipal stormwater & sewage pipes, power and communication pipes
    Packaging: hollow boards, packaging boxes
    Films & bags: biodegradable mulch films, shopping bags, inner bags, stone paper
    Others: paints, coatings, non-woven fabrics, highway anti-glare boards, composite resin manhole covers, power cover plates, flower boxes, manure leakage boards
    Compatible with a wide range of polymers: PP, PE, PVA, PMMA, PAM and more.

    🔹 Building Material & Cementitious Sector
    With special additives, it can be made into cementitious materials for:
    Anhydrite self-leveling mortar
    Gypsum-based tile adhesive
    Various gypsum-based building materials
    Produced by Guizhou Phosphate Chemical Group
    Dual Guarantee of Quality & Capacity

   Produced by GPC，Dual Guarantee of Quality and Production Capacity

    As a core product of GPC’s green environmental protection sector, Crystal-Converted Calcium benefits from the Group’s strong resources and technological strength:
    Abundant phosphogypsum supply with stable quality, high whiteness, low impurities, extremely low heavy metal and radioactivity levels
Annual capacity of 100,000 tons for stable large-scale supply, Years of expertise in phosphogypsum comprehensive utilization; participant in developing multiple national, industrial and local standards; holder of dozens of authorized patents.   

    Supporting annual capacity of 25,000 tons for deep-processed products including anhydrite masterbatches and packaging boxes, providing integrated solutions from raw material to finished product from industrial by-product to multi-functional new material,
   

   Crystal-Converted Calcium proves that green manufacturing and economic benefits can go hand in hand.
