Mold release additives are designed to improve your injection molding process by reducing friction, allowing more efficient processing and improving part quality time after time. IncroMold Our IncroMold range of mold release additives can be added directly into the polymer melt or via a masterbatch at around 0.5% to give a number of benefits in processing and finished parts. Key Benefits Consistent mold release Reduced cycle times Continuous running Scratch and scuff resistance Improved flow and dispersion of filled polymers Improved surface finish Fewer rejects and waste Reduced machine wear and cleaning Improved pigment dispersion.

Scratch resistance is important in high quality parts such as automotive interiors, household appliances and high-end cosmetic packaging. Our mold release additives also have the added benefit of improving scratch width and appearance by reducing friction at the polymer surface. Other post-molding benefits include lower torque release, improved de-nesting, reduction in assembly force, improved pigment dispersion and a reduction in the number of rejects. Case study: Increased output and cost reduction in PP molding A manufacturer of polypropylene parts for electric showers approached Croda wanting to increase production output and save costs. They were producing 71 shots per hour but had to use silicone spray as a mold release agent. The silicone spray was applied inconsistently and was difficult to remove from the surface of the finished parts, resulting in a sticky residue on the part. Croda recommended using IncroMold S at 0.5% to eliminate the use of silicone and allow continuous production. The customer found that they were able to produce 82 shots per hour (an increase of 15%), as well as reduce cycle times from 55 to 44 seconds (an improvement of 20%). By using IncroMold S, the customer observed that the improvement in mold release also resulted in more consistent quality parts, fewer rejects and a reduction in pin marks.
