See What we do
Interfacial has developed a novel method for manufacturing the market’s highest filled masterbatches (MBs). The manufacturing method consists of three-steps: pre-coating of mineral or filler, removal of liquid carrier, and pelletization. Utilizing this technology, Interfacial has designed, developed and manufactured MBs consisting of inorganic and organic fillers that have 75 wt% to 95 wt% loading level in polyolefin, polyamide, polyester, and other carrier resins. Some of the significant advantages and benefits of this technology include:
- Excellent dispersion of MB in main resin leading to enhanced properties
- Lower cost MB due to effectiveness of processing method
- Low temperature process that eliminates degradation of heat sensitive additives and/or fillers
Another major benefit of this technology is that it turns typically difficult-to-handle materials into MBs that are much safer, cleaner, and easier to handle. This includes hard-to-handle materials such as low bulk density conductive carbon blacks, nano and thermally conductive graphites, and carbon nanotubes. Called “Clean Carbon” due to the densification of these low bulk density powders, throughputs are increased since the pellets feed in much like conventional MBs. Another benefit is that transportation costs improve since companies can now package more material due to the fact that the pellets are tough and survive shipping in large totes. Furthermore, Interfacial has demonstrated that its low shear process can maintain the structure of conductive carbon black leading to performance similar to as-received powders. This game-changing discovery allows companies who handle these materials to maintain cleaner facilities as well as the reduction of these conductive materials causing issues with processing equipment.
