PurTone RX

PurTone Rx Color Concentrates

Color Concentrates for the strictest medical applications

Compounding Solutions’ PurTone Rx color concentrates use USP Class VI and/or FDA 21 CFR part 73 subpart D components, which are exempt from batch certification for use in medical devices. Our color concentrates suggested let down ratio is 4% for all of your injection molding and tubing extrusion applications and they are made using the resin of the application rather than using a universal carrier.
 
Universal carrier resins are commonly used in color concentrate production, such as polyethylene (PE) or Ethylene Vinyl Acetate (EVA). They can work for some applications however due to stringent regulatory body guidelines, the use of universal carrier color concentrates is less than ideal to say the least. Matching the base resin of the color concentrate with the resin chosen for the project is the ideal match. Having the same base resin chemistry will ensure compatibility, great mixing into base resin, and ease of processing.
