Product description

Toray’s TC250 offers an excellent balance of toughness, mechanical properties, and hot/wet performance. It is easily processed via vacuum bag/oven, autoclave, or press curing operations. Although TC250 is a 130°C (265°F) cure system, it can be post cured for a higher dry and wet Tg, which enhance the product’s elevated temperature performance. TC250 can also be cured or freestanding post cured to 177°C (350°F) to increase its high temperature performance.

TC250 is available with virtually all fiber reinforcements in unidirectional tape, slit unidirectional tape, woven and non-woven prepreg formats.
