Pekutherm “TI2” is a physical action Purging Compound, that stridently scours away outgoing plastic, built up previous material, burnt on residues, expels color and off specification contaminants including gas residues from inside of a Hot Runner System. Pekutherm “TI2” has no chemical reactant and hybrid lubricant. It does have a carrier resin unlike any other formulation of Pekutherm. This formulation is made exclusively for Hot Runners. Pekutherm “TI2” does contain a mild abrasive and does not function as all the other formulations. [*Warning*] because Pekutherm “TI2” does not melt completely, it’s not advised to be used on small orifice gates or indirect gates.
