T-Ply products (commonly known as Hot-Tops and Cap Boards) are insulating mineral-based specialty
products used to line the insides (Cap Boards) and tops (Hot-Tops) of steel ingot molds.
Designed to be either preset in the mold prior to teeming, or placed on the rising metal at the end of
the mold fill, Thermatex Exothermic/Insulating Cap Boards are used in place of more traditional
powders to improve existing hot topping operations by maintaining the steel temperature in the head of
the riser during solidification.
Thoroughly tested and field proven, Thermatex T-Ply Hot-Tops and Cap Boards allow molten steel to fill the
body of the mold as solidification occurs during the cooling stage. This results in improved
segregation pattern, pipe reduction, and elimination of smoke and fume difficulties, all of which
reduce hot topping costs and improve performance and quality.
Thermatex products are designed to maximize the yield of sound metal through uniform mold coverage,
resulting in a consistent and high purity steel that is mandatory for products such as bearing steels,
valves and valve bodies, mining/drilling equipment and other critical applications.
Thermatex Ingate Gaskets are designed to be placed around the ingate prior to the ingot mold being set in place, forming a protective "ring" .
The barrier created reduces spillage, waste, cleanup time and of course, cost. Adjustable, universal fit.
Thermalite ceramic fiber material is a blend of high purity silicate ceramic fibers, combining both organic and
inorganic binders for handling strength and shape integrity at high working temperatures.
It resists oxidation, reduction, and attack from most corrosives. Thermalite vacuum-formed shapes can be surface treated
on one or both sides, forming an inorganic protective shell for extra strength, or impregnated throughout the entire shape
for an almost rock hard density making them the strongest of all vacuum formed products. Custom shapes and special applications as well as inorganic formulations are available including
Thermalite flexible wet blankets molded to almost any surface configuration.
High temperature gaskets
Flue and exhaust liners
Metal contact heat shields
