Activated Precipitated Calcium Carbonate is surface‑activated precipitated calcium carbonate as direct replacement for Shiraishi P‑50. Surface organic treatment enhances the compatibility between calcium carbonate and polyolefin as well as PVC resin. When incorporated into PVC profiles, sealant and PP modified formulations, this mineral filler improves product toughness, reduces shrinkage and optimizes extrusion processing performance.

Product Detail

Product Overview Activated Precipitated Calcium Carbonate (CAS 471‑34‑1, Shiraishi P‑50 Equivalent) is precipitated calcium carbonate with fatty‑acid surface activation treatment. Fine‑controlled particle size and modified surface deliver good wet‑out with non‑polar polymer matrix. During extrusion and kneading processing for PVC profiles, construction sealants and modified‑PP compounds, the filler disperses evenly inside resin. It enhances notched toughness of polymer parts, lowers molding shrinkage, improves dimensional stability and optimizes melt fluidity for extrusion production. This activated precipitated calcium carbonate is widely used for rigid PVC profile, plastic modification and elastic sealant formulations.

Key Features ‑ Fatty‑acid surface activation improves resin‑filler interfacial compatibility ‑ Improves notched‑toughness performance for PP and rigid PVC polymer compounds ‑ Reduces molding shrinkage and enhances dimensional stability of molded articles ‑ Optimizes melt fluidity for plastic extrusion and sealant compounding processes ‑ Direct functional equivalent grade for Shiraishi P‑50 activated precipitated calcium carbonate

Typical Technical Properties ‑ Chemical Type: Fatty‑acid activated precipitated calcium carbonate ‑ Appearance: White free‑flowing fine powder ‑ Median Particle Size: Refer to TDS ‑ Bulk Density: Refer to TDS ‑ Activator Content: Refer to TDS

Applications ‑ Rigid PVC profile: Functional filler for window and door profile extrusion compound ‑ Modified PP compound: Toughening mineral filler for polypropylene modified granules ‑ Construction sealant: Reinforcing filler for elastic joint sealant formulations ‑ Polymer compounding plant: Raw activated PCC for thermoplastic and sealant production

Processing Recommendation Add activated precipitated calcium carbonate during high‑speed mixing or kneading stage. Adjust filler loading according to targeted toughness and shrinkage requirements. Ensure sufficient homogenizing mixing. Complete lab trials before mass compounding production.

Storage & Handling Store in cool, dry warehouse and avoid moisture absorption. Reseal packaging immediately after opening. Wear dust‑proof mask and protective gloves when handling fine mineral powder.
