Product Description
Ground Calcium Carbonate 325-3000 Mesh for Rubber Plastic Filler
Product Description
Ground Calcium Carbonate for Rubber/Plastic Filling (325-3000 Mesh)
Product Positioning
A series of filler-grade calcium carbonates specifically developed by Hongjian Chemical for the rubber and plastic industries. Utilizing advanced dry grinding and precise classification technology, we provide a full particle size range from 325 mesh (~45μm) to 3000 mesh (~5μm).
Core Value
- Full Particle Size Coverage: Finely divided mesh grades accurately match customer processes.
- Cost-Effectiveness Balance: Seeks the optimal balance between performance and cost.
- Quality Stability: Fully automated production lines ensure high batch-to-batch consistency.
Product Mesh Classification & Application Guide
Coarse Mesh Series (325-800 Mesh)
- 325 Mesh (d97 ≈45μm):
Applications: PVC profiles, pipes, sheets, rubber conveyor belt base layer.
Characteristics: High filling capacity, good flowability, low equipment wear. - 800 Mesh (d97 ≈18μm):
Applications: Plastic crates, chairs, rubber soles.
Characteristics: Balances mechanical properties and cost, primary choice for basic applications.
Medium Mesh Series (1250-1500 Mesh)
- 1250 Mesh (d97 ≈10μm):
Applications: Automotive plastic parts (door panels, dashboards), rubber sealing strips.
Characteristics: Good surface smoothness, high retention of impact strength. - 1500 Mesh (d97 ≈8μm):
Applications: PVC calendered film, artificial leather, foam rubber.
Characteristics: Excellent dispersibility, fine product feel.
Fine Mesh Series (2000-3000 Mesh)
- 2000 Mesh (d97 ≈6μm):
Applications: High-end cable compounds, TPE/TPR, precision rubber products.
Characteristics: Significant reinforcement effect, marked improvement in tensile strength. - 3000 Mesh (d97 ≈5μm):
Applications: Transparent PVC products, silicone rubber, high-end engineering plastic alloys.
Characteristics: Performance close to functional fillers, minimal impact on transparency.
