AMERICHEM INC.

Specialty lubricant concentrates for most thermoplastics reportedly improve wear resistance and mold release, reduce warpage and rejects, lower material and energy costs, make finishing easier, and reduce tool wear. Available in cubes, pellets or as powders, alone or in multifunctional concentrates with other additives and/or colors.

AXEL PLASTICS RESEARCH LABORATORIES

Mold Wiz internal lubricants and processing aids are complex polymeric blends containing no wax, silicone, or metallic stearate. Nonexuding additives are mixed into thermoplastics, thermosets, and rubbers at levels of 0.1-1% by weight.

Products compounded into thermoplastic resin or dry blended by end user. Synergistic effects reduce melt temperatures and increase melt flow index for faster cycle times at lower temperatures. Improved resin flow allows easy fill of deep draw cavities, with smooth release of thin-walled parts. No warpage when releasing parts from cores or threaded molds. Better wetting of reinforcements and aided elimination of buildup, flow marks and weakness in the weld line. Molds remain clean; no solvent vapors are released. Molded parts ready for painting, bonding, printing or plating without degreasing. Many products FDA approved.
