Can you color TPEs? Can you color TPEs? Because their natural color is usually cream, white, beige or translucent, TPEs are very easy to color.

Although PVC is one option, this manufacturer needed a colorable, drop-in replacement for PC/ABS. From there, the Avient team identified material options that offered high flame retardancy and finally, requirements for processing flexibility and colorability were applied. The results showed the Avient material outperformed typical FR PC/ABS and had an added bonus: a UL yellow card V0 flammability rating for all colors and some thicknesses.* Avient also used its custom color matching capabilities to provide pre-colored material that simplified molding, while the material’s wide processing window helped accommodate a variety of molding environments. * V0 @ 1.5 and 3.0mm FR PC/ABS failed 0% 20% 40% 60% 80% 100% 120% 140% Virex TB Clorox Broad Spectrum CaviCide SaniCloth Plus wipes FR PC/ABS failed FR PC/ABS failed FR PC/ABS failed FR PC / ABS (1.0% Strain) FR PC / ABS (1.5% Strain) Trilliant HC (1.0% strain) Trilliant HC (1.5% strain) FR PC/ABS failed 0% 20% 40% 60% 80% 100% 120% 140% Virex TB Clorox Broad Spectrum CaviCide SaniCloth Plus wipes FR PC/ABS failed FR PC/ABS failed FR PC/ABS failed FR PC / ABS (1.0% Strain) FR PC / ABS (1.5% Strain) Trilliant HC (1.0% strain) Trilliant HC (1.5% strain) TENSILE STRENGTH RETENTION AFTER 7 DAYS EXPOSURE Both materials were tested according to ASTM D543 for 7 days.
