Non-hazing mold release for soft TPOs.


A new proprietary processing aid for molding high-impact, soft-touch TPOs is said to provide enhanced flow and excellent release of parts from mold cavities while leaving parts residue-free. MoldWiz INT-33PAS from Axel Axel: see Absalon.  Plastics Research Laboratories, Woodside, N.Y., is offered as a free-flowing powder or 100%-active pellet pel·let

1. A small pill; a pilule.

2. A small rod-shaped or ovoid mass, as of compressed steroid hormones, intended for subcutaneous implantation in body tissues to provide timed release over an extended period of time.
 and is typically used at 0.3%.

Axel sources say soft TPOs can be difficult to release, but INT-33PAS is designed to provide easy mold release while also ensuring that consistent color and surface finish can be maintained throughout the life of a molded part. INT-33PAS was developed to address "hazing Hazing is an often ritualistic test and a task, which may constitute harassment, abuse or humiliation with requirements to perform random, often meaningless tasks, sometimes as a way of initiation into a social group.
