Green Oxide Pigments for Plastics
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
The Heat-Proof Choice for Global Plastics
Deqing Demi Pigment Technology Co., Ltd. provides the "Thermal Shield" for the polymer industry. We recognize that in high-speed plastic processing, color stability is critical. Our plastic-grade green is manufactured to ensure zero "bleeding" or plate-out on molds. We provide the "Inert Green" that allows plastic manufacturers to create high-durability products—from stadium seating to industrial piping—with total color security.
Plastic Green Usage Areas
- Masterbatch: High-concentration green bases for universal plastic coloring.
- Outdoor Furniture: UV-permanent green for HDPE and PP furniture.
- Engineering Plastics: Heat-stable green for under-the-hood automotive parts.
- Plastic Pipes: Chemical-resistant green for industrial and water transport piping.
Plastic Green Technical Specs
| Metric | Value | Standard |
| Heat Resistance | Up to 1000∘C | Muffle Furnace Test |
| Moisture Content | Max 0.2% | ISO 787-2 |
| Migration Resistance | Grade 5 (Excellent) | ISO 105-X12 |
| Cr2O3 Content | Min 98.5% | ISO 1248 |
| Filter Pressure Value | Low (Premium) | EN 13900-5 |
Performance Characteristics
- Absolute Thermal Stability: Will not shift color during high-heat molding.
- Zero Migration: Will not "bleed" into adjacent colors in multi-layer plastics.
- Weather Protection: Acts as a natural UV stabilizer for the host polymer.
- Chemical Resistance: Stable against a wide range of oils, fuels, and industrial solvents.
Q: Is this green safe for toys?
A: Yes, our high-purity chromium greens are non-toxic and comply with EN 71 and FDA standards.
Q: Does it cause "Plate-out" on the extruder screw?
A: No, its inorganic nature and fine grind ensure clean processing without residue buildup.
Polymer Engineering Services
We offer "Filter Pressure Testing (FPV)," ensuring our green is clean enough for use in thin plastic films and fibers.
Custom Pre-Blended Masterbatch Bases: We can provide the green oxide in a pre-wetted form for rapid masterbatch compounding.
The Science of Thermodynamic Rigidity
In plastic processing, pigments are subjected to "Thermal Kinetic Energy." The science behind our plastic-grade green lies in its "Crystal Lattice Energy." Because Chromium Oxide has such high internal bonding energy, the atoms cannot be rearranged by the heat of an extruder (200∘C−300∘C). This scientific fact ensures that the "Coordination Environment" of the chromium ion remains constant, preventing the color shifts that plague organic pigments in high-performance polymer applications.
