Salient Features:-
Purity
Long shelf life
Safe to use

Other Details:-
An exothermic powder which is applied to the feeder head. When Exothermic Reaction of AVA APC Powder is complete, the burnt out material expands and has strong insulating factors which reduces heat loss by radiation. Used for all grades of Iron/ Steel castings especially when feeder heads indicates a requirement for a medium sensitivity exothermic anti piping compound.

Function:-
Anti Piping Compounds are used to prevent the considerable heat loss to atmosphere that can take place from uncovered risers, As long as the surface of the open of the top feeder remains liquid, atmospheric pressure exerts its powerful influence in the feeding of castings. Unfortunately often it is lost when the sculling of the metal acts as a barrier to atmospheric pressure and the riser then, only has its own gravitational ,mass to promote feeding

Types:-
Expandable
Non-Expandable
