Mold releases for RTM, Nylon & TP elastomers. (Additives).

Three new mold releases for specific applications will be featured by Mel Plastics Research Laboratories, Woodside, N.Y.

* Xtend 825 is a semi-permanent, high-slip release specially designed for thermoset RTM composites, especially with non-gelcoated parts and difficult resins like DCPD polyesters. Xtend 825 is a reactive resin solution that cures to a densely cross-linked film. It provides multiple releases from the "B" or plug side of molds. This solvent-based product contains no HAPS (hazardous air pollutants) and can be applied at 100 to 200 F, so there is no need to remove RTM molds from service for each new release application.

* MoldWiz INT-1117EL is an internal mold release designed to improve processing and release of new EPDM-containing TPOs, TPEs, and TPUs for products ranging from footwear to automotive mechanical goods and electronic keypads.

* MoldWiz INT-38-HM is an internal release that improves flow and release of nylon and other engineering resins that are dried at temperatures up to 125 F. It has a drop melt of 252 F, so users can now blend the lubricant and resin prior to drying with no fear of melt-out. Available as a 100%-active pellet or free-flowing powder, it is a proprietary formulation of modified fatty acids that are suitable for food contact, Axel says. Tel: [phone], www.axelplasics.com
