Pigments Powder for Rubber and Elastomers

High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.

Leading Supplier for the Global Rubber Industry

Deqing Demi Pigment Technology Co., Ltd. provides the rubber and elastomer market with pigments that offer superior durability and ease of integration. Our pigments are manufactured to ensure they do not contain copper or manganese "poisons" that can degrade natural rubber. We work with manufacturers of automotive seals, industrial belts, and consumer rubber goods to provide coloring solutions that enhance the product's aesthetic while maintaining its critical physical properties.

Rubber Application Segments

  • Automotive Components: Color-coded hoses, seals, and gaskets.
  • Industrial Belting: Durable coloring for conveyor belts and drive belts.
  • Footwear Soles: High-abrasion resistant pigments for sneaker and boot soles.
  • Flooring and Mats: UV-stable pigments for EPDM gym flooring and playground surfaces.

Functional Characteristics for Elastomers

  • Antioxidant Compatibility: Does not interfere with anti-aging additives.
  • Non-Migratory: Ensures color does not "bloom" or bleed to the surface of the rubber.
  • Excellent Weatherability: High resistance to ozone and UV-induced cracking.
  • Steam Stability: Remains stable during high-pressure steam vulcanization.
  • Q: Does the pigment affect the "rebound" of the rubber?

    A: No, our inorganic pigments are used at low concentrations and are physically integrated into the matrix, preserving the elastomer's natural resilience.

  • Q: Are they suitable for Silicone rubber?

    A: Yes, our high-purity iron and chrome oxides are excellent for liquid and high-consistency silicone rubbers due to their thermal stability.

Rubber Formulation Assistance

We provide guidance on "staining" versus "non-staining" pigment options to ensure the rubber product does not mark adjacent surfaces.

Compounding Support: Our team can assist in optimizing the "Master-batching" of the pigment into a rubber base to ensure 100% dispersion during the final milling or Banbury mixing stage.

Surface Interaction and Dynamic Color

Color science in elastomers involves measuring "Stress-Induced Whitening" (or lack thereof). We ensure our pigments have a strong affinity for the polymer chain, preventing micro-voids that cause color fading when the material is stretched. We use CIELab data to monitor color consistency before and after vulcanization, as the chemical change in the rubber binder can slightly shift the refractive index. By providing pigments with stable Lab* coordinates, we ensure that the finished rubber part matches the original design specifications.
