The packaging industry, particularly for PET bottles, demands colorants that offer not only vibrant aesthetics but also robust performance during processing and throughout the product's lifecycle. When it comes to achieving a striking red hue for PET bottles, Solvent Red 135 (CAS 20749-68-2) has emerged as a preferred choice. As a leading manufacturer and supplier of specialty dyes in China, we are proud to offer this high-performance dye tailored for such demanding applications.

PET (Polyethylene Terephthalate) is widely used for beverage bottles due to its clarity, strength, and barrier properties. Coloring PET requires dyes that can withstand the high processing temperatures involved in bottle manufacturing, such as extrusion and blow molding. Solvent Red 135 excels in this regard due to its:

  • Exceptional Heat Resistance: With a heat resistance temperature of up to 300°C, Solvent Red 135 maintains its color integrity and brilliance even under the high thermal stress of PET processing. This makes it an ideal candidate for purchase by PET bottle manufacturers.
  • Transparency: Unlike opaque pigments, solvent dyes like Solvent Red 135 dissolve into the PET matrix, preserving the bottle's transparency while imparting a beautiful, clear red color. This is crucial for product appeal and visibility.
  • High Tinting Strength: Minimal amounts of the dye are needed to achieve a deep, consistent red, contributing to cost-effectiveness in large-scale production.
  • Excellent Lightfastness: The dye's resistance to UV degradation ensures that the color remains stable over time, even when exposed to light, extending the aesthetic appeal of the packaged product.

For procurement managers and formulators in the PET industry, selecting the right dye is a critical decision. We, as a reliable supplier in China, ensure that our Solvent Red 135 meets high purity standards, guaranteeing consistent results. When you buy from us, you benefit from our expertise in chemical manufacturing and our commitment to delivering quality.

The process of dyeing PET with Solvent Red 135 typically involves masterbatch production, where the dye is pre-dispersed in a PET carrier resin. This masterbatch is then let down into the main PET resin during bottle manufacturing. Our technical team can provide guidance on optimal dispersion and coloration levels to achieve your desired shade and performance. We invite you to request a quote and sample to evaluate the superior performance of our Solvent Red 135.

As a trusted manufacturer, we are dedicated to supporting the packaging industry with innovative and reliable coloration solutions. Solvent Red 135 offers a distinct advantage for PET bottle coloration, delivering both visual appeal and functional performance. Partner with us to ensure your PET products stand out with a brilliant and stable red.
