CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Manufacturer profiles associated with Pigments and Colorants.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
High-quality silicone rubber pigments maintain color stability up to 200°C continuous exposure, with some specialized formulations resisting temperatures up to 250°C for short durations.
Properly dispersed pigments at recommended loading levels (typically 0.5-5%) have minimal impact on mechanical properties. Excessive loading or poor dispersion can reduce tensile strength and elongation.
Inorganic pigments (metal oxides) generally offer better heat and UV resistance but limited color range. Organic pigments provide brighter colors and wider range but may have lower thermal stability.
