PL-S Parting Line Sealer for rotomolding support


Helping Rotomolders To Eliminate Costly Repairs

PL-S® Parting Line Sealer is a unique polymer compound that resists flow at high molding temperatures during the rotational molding cycle.

It is a pliable compound that cures in the mold during the molding process and fuses to the outer skin of the part. The excess material can be easily trimmed away using standard flash-removal tools.

PL-S Parting Line Sealer was developed for one reason…to keep your resin in the mold where it belongs during the molding cycle.
