Process aid additive used with phenolic BMC.

This manufacturer's internal mold release and process aid additive, INT-326PWD, has been designed specifically for use with powdered novolac resins, and especially for phenolic bulk molding compounds (BMC).

Use of this MoldWiz INT-326PWD additive, is said by the company to result in a number of very significant benefits. Parts are said to release cleanly from the mold, and all parts will be ready for secondary processing without the need to de-grease the parts to achieve secondary surface adhesion, according to the company. Also, there is said to be no detriment to the physical properties of the molded part.

INT-326PWD is a proprietary blend of copolymers, crosslinked polyolefins and organic phosphate esters with modified fatty acids. The recommended level of addition of the INT-326PWD powder is generally 1% by resin weight, according to the manufacturer.

The maker of INT-326PWD is an ISO 9001 registered company offering over 600 process or resin specific process aid additives and external release agents under the trade names Xtend and MoldWiz. All of the company's products are said to be formulated from raw materials that comply with the chemical substance inventory lists of TOSCA, DSL, METI, EINECS, Australia and Korea.
