Most compounders would rather sell compounds and not worry about color. Yet, many have found it difficult to color compounds at the press, particularly when molding with combinations of opaque compounds that are glass-filled or with high levels of talc, flame-retardants, or other functional additives.
As such, many manufacturers have made the switch to in-mold coloring of plastic parts to avoid the headache associated with meeting the Federal Clean Air Act’s rules. However, not all methods of in-mold colors have been proven to reduce cost. But, molders who made the switch to using highly loaded colorant like Carolina Color’s G3 in solid pellet form have seen significant cost savings.
The basic science behind Carolina Color’s G3 pellet technology is to add smaller quantities of more concentrated colorant to virgin resin to achieve the same end result as opposed to using larger amounts of conventional colorant. There are numerous benefits to doing so, not the least of which is improved physical properties.
Carolina Color’s G3 was specifically developed for molders looking to widen their processing window while lowering their cost to color nylons, ABS, and other engineered resins such as PC, PBT, PC-PBT alloys, and more. G3 with its high levels of pigment and excellent dispersion and distribution makes it easier to color compounds at the press.
G3 can be used for under-the-hood, external and interior transportation parts; electronic/electrical markets and medical devices markets; and products; building and construction materials; appliances; housewares, lawn and garden and power tool segments.
Key attributes and advantages to using G3 include:
– Provides highest pigment-loaded custom colors in the industry
– Can be used in both olefins and engineering resins
Carolina Color G3 features include:
– Low softening point allows good color incorporation
– Low use rates
– Highest industry loadings of pigments, dyes and additives.
-Low processing temperatures during compounding minimizes heat history of thermally sensitive colorants and additives
-Provides a good option for processers converting from pre-colored resins to color concentrates
– No screw slippage issues, unlike liquid color and wax-based products
