Blue Pigments for Rubber and Polymer Use
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Global Partner for Blue Polymer Colorants
Deqing Demi Pigment Technology Co., Ltd. provides the global polymer and rubber industries with a versatile range of blues. From the deep "Royal Blue" of phthalocyanines to the bright "Cobalt" tones of ultramarines, we ensure our blues are the highest purity available. We understand the regulatory landscape (REACH/FDA) and ensure our blue pigments meet the stringent safety requirements of the medical, toy, and food-packaging sectors.
Rubber & Polymer Application Areas
- Automotive Hose & Seals: Heat-stable blue for under-the-hood components.
- Consumer Goods: Vibrant blue for toys, household appliances, and electronics.
- Sports Equipment: Durable blue for rubberized tracks and gym flooring.
- Medical Tubing: High-purity blue for clinical and laboratory equipment.
Rubber & Polymer Blue Specs
| Metric | Value | Standard |
| Lightfastness | 7 - 8 | Blue Wool Scale |
| Heat Stability | 200∘C−280∘C (Grade dependent) | DIN 53772 |
| Heavy Metal Content | ND (Not Detected) | EN 71-3 / RoHS |
| Migration Resistance | Grade 5 | ISO 105-X12 |
| Oil Absorption | 35 - 50 g/100g | ISO 787-5 |
Attributes for High-End Coloration
- Vibrant Saturated Hues: Achieves "brilliant" blues that stand out in retail environments.
- Excellent Chemical Resistance: Unaffected by acids, oils, and industrial chemicals.
- Safe for Consumer Contact: Complies with global safety standards for skin-contact items.
- Non-Warping in Plastics: Does not cause shrinkage issues in injection-molded parts.
Q: Can these be used in EPDM rubber?
A: Yes, our blues are fully compatible with EPDM and do not interfere with the peroxide or sulfur curing cycles.
Q: Is there a "Blue" for transparent plastics?
A: Our high-transparency phthalocyanine grades are ideal for creating clear, deep-blue "Jewel" tones in resins like PS or PC.
Regulatory & Safety Compliance
We provide full documentation for "Food Contact" and "Toy Safety" applications, ensuring our clients can export their finished products to any global market without regulatory hurdles.
UV Longevity Testing: We offer accelerated UV testing on specific polymer/rubber plaque samples to demonstrate how the blue hue performs over 2000+ hours of intense exposure.
The Science of Blue Light Scattering
In polymers, we focus on the "Scattering Coefficient" (S). Blue pigments have unique interactions with light due to their molecular structure. We monitor the "Mass-tone" and "Tint-tone" consistency to ensure that whether the pigment is used at 100% or 1%, the color remains predictable. By optimizing the particle size to the 150-250nm range, we maximize the "Blue Undertone," resulting in a cleaner, more premium aesthetic in the final molded product.
