HYTAC® WF is a high strength, high clarity thermoset epoxy syntactic plug assist material that maintains a performance characteristics even at temperatures up to 450°F (230 °C). Designed to result in improved clarity for APET and other clear polymers, HYTAC® WF incorporates glass spheres less than ½ the diameter of most syntactic foams. This translates to a more easily polished surface finish and provides nearly three times the strength and twice the stiffness of standard epoxy syntactic plugs.

Hytac® XTL is the latest generation of syntactic foams with enhanced toughness and superior machinability. This material is easy to machine and polish without dust. HYTAC-XTL is suitable for a wide range of plastics and allows users to machine fine details.

HYTAC® C1R is a toughened copolymer thermoset syntactic foam modified to provide high friction and the highest durability of any copolymer syntactic foam. Relatively new to the market (introduced in 2012) it has gained popularity for deep draw or zero draft application areas where high friction is needed. C1R was featured in the show daily at NPE 2015 after successful trials with Milliken Chemical and uVu Technologies demonstrated superior performance with transparent PP. Excellent surface characteristics are obtained straight from machining and may be easily modified with sandpaper to carry more or less material into the mold as needed. It may be polished to a very smooth surface when necessary for working with transparent plastics.

HYTAC® W was CMT’s first commercially-produced epoxy syntactic foam. With low thermal conductivity and CTLE associated with the syntactic structure, it proved to the thermoforming industry that felt-covered wood plugs could be resigned to the dustbin of history. While still used in low-volume or low-cost applications, W has been supplanted by other, superior levels of HYTAC® materials. It has low thermal conductivity and specific heat, this translates to lower heat transfer reducing warm-up time and virtually eliminating material sticking to the plug. It is dimensionally stable which means, that the low coefficient of thermal expansion means the plug maintains its shape over a wide temperature range.
