Hongjian Chemical GCC Product Series
1. Plastic Special Series - "Functional Filling Additive"
PVC Profile/Pipe Grade: Concentrated particle size distribution (d97: 15-25μm), low oil absorption, effectively improves product stiffness, heat deflection temperature, and dimensional stability, reducing production costs.
Polyolefin Masterbatch Grade: High whiteness (≥95%), good compatibility with carrier resin, suitable for preparing high-fill ratio (70-85%) masterbatches with excellent dispersion.
2. Coating Special Series - "Cost-Effective Functional Filler"
Interior Emulsion Paint Grade: Fineness 800-1250 mesh, excellent suspension and film feel, can partially replace titanium dioxide to reduce costs.
Industrial Paint Grade: Strong weather resistance, high chemical inertness, improves coating corrosion resistance and wear resistance, suitable for primers, intermediate coats, and marine paints.
3. Rubber Special Series - "Semi-Reinforcing Filler"
General Rubber Products Grade: Can partially replace carbon black and silica, improves processing performance, increases product hardness, modulus, and wear resistance.
Light/Colored Rubber Products Grade: High whiteness, does not affect product color, high filling capacity, significant cost advantage.
Silicone Sealant Grade: Extremely low moisture content (≤0.2%), good compatibility with the system, provides suitable thixotropy and extrudability, prevents settling.
Building Putty/Grout Grade: Reasonable particle morphology, improves workability and sandability, enhances product hardness and crack resistance.
