In Tests by Teknor Apex, New TekTuff™ PS Colorants Substantially Boost Dart Impact

PAWTUCKET, RI, U.S.A., May 27, 2015: New impact-modified concentrates enhance the toughness of styrenic polymers while imparting the same bright colors available with corresponding unmodified concentrates; it was announced today by Teknor Apex Company.

TekTuff™ PS concentrates increased impact strength by 45 to 90%, depending on use level, in ASTM D5628-10 falling dart tests conducted by Teknor Apex.

“This is in addition to our functional concentrate product line,” says John Wood, technical manager, Teknor Color Division. “We feel this has applications at many plastic processors.”

The new concentrates are recommended for housewares, toys, disposables, and packaging. They are available on a custom basis, including new color matches as well as any existing color.

The introduction of TekTuff PS concentrates follows last year’s announcement of a TekTuff series of color concentrates for providing impact resistance in polyolefins.
