Color Concentrates for the strictest medical applications
Compounding Solutions was founded with the concept to enhance existing color concentrate standards in the medical industry. We started as a specialty medical compounder and we remain as such. Highly effective dispersion of pigments and additives via our unique screw designs ensure great surface finish in thin walled tubing or micro-molded parts. Compounding Solutions mastered loss in weight feeding technology many years ago which further enhanced our compounds and concentrates consistency, pellet to pellet, lot to lot. Compounding Solutions produces all of our medical color concentrates inside our environmentally controlled white room Read More… and compliant to ISO 13485 quality system.

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.
