For more than 50 years, Penn Color has been at the forefront of developing and producing the highest quality color & additive master batches for the plastics industry. We are among the largest custom master batch producers in North America, and paired with our privately-held & family-run ownership; we have all the resources and buying power of the large suppliers, yet maintain a responsive and agile approach to our customer relationships as a smaller supplier would. Technology is at the core of what we do best. Our research & development team includes professionals with advanced degrees in polymer, physical, organic and analytical chemistries, knowledge of color trends & styles, and strong backgrounds in color matching for all thermoplastic resins.
