However, these high- heat materials require much higher mold and melt temperatures than typical plastics such as polypropylene (PP), nylon and polycarbonate (PC). To mold high-performance thermoplastics, processing equipment must be capable of melt temperatures up to 400°C and mold temperatures up to 200°C. These can range from viscosity changes that affect consistency of the molding process to dimensional stability and aesthetics of the finished part.

In addition, they process easily on standard injection molding machines and can be overmolded to simplify your production process. Ability to add surface texture – Our injection molded TPEs are easily processed in commonly used, complex molds. Our materials allow you to add surface texture by bead blasting or chemically texturing the mold.

HVAC doors are typically produced by injection molding two parts that provide structural strength and air sealing performance. This global reach also allowed Avient to respond quickly to mold trials, and eliminate import and shipping challenges. Avient engineered a new customized formulation for the part, which provided both the processability required for extremely short cycle injection-compression molding, as well as including an additive to stabilize the material when in contact with copper.

Colorant Chromatics™ PEI Masterbatch Colors for High-Temperature Injection Molding Applications Colorant Chromatics™ PEI colorants are specifically designed to color polyetherimide (PEI) resin used in high-temperature injection molding applications. Formulations are heavy metal free and manufactured using state- of-the-art pigment dispersion techniques that improve homogenization and color distribution during injection molding. KEY CHARACTERISTICS • Consistent coloring and improved homogenization with the polymer offer more efficient processing and waste reduction • Opaque PEI masterbatches available with shorter lead times and a range of readily available standard colors • Minimum order quantities as low as 5kg (10 lbs) for improved inventory control • Robust colorant formulations mean no disruptions to existing molding processes, allowing manufacturers to bring products to market faster and without investing in new machinery FEATURES AND COLORS PEI colorants are manufactured using 100% prime virgin PEI resin.
