Applying expertise in specialty compounding and masterbatch technologies to its popular long fiber thermoplastic (LFT) product line has enabled RTP Company to commercialize a new polypropylene LFT concentrate designed to meet demanding automotive specifications.
The melt impregnated LFT concentrate, grade designation RTP 199 X 118012, combines 60% by weight very long glass fiber reinforcement and masterbatch additives into a single pellet, allowing processors to easily blend it with neat polypropylene resin at the press.
“Our LFT concentrate is directed towards processors with large volume needs and engineered for shop floor simplicity,” said Eric Lee, Business Manager—Structural Products. It is ideal for injection molding applications such as automotive front-end modules and door plates, as well as large profile extrusions.
The LFT concentrate can be used to elevate stiffness, impact resistance, and long-term endurance of polyolefin materials when diluted to long glass fiber levels of 20 to 40% in finished goods. Masterbatch additives are included to achieve superior dispersion, allowing the LFT concentrate to be blended with materials of varying melt flows.
“Processors appreciate our experience, because it provides confidence that our assessment skills will result in a solution that addresses their business needs first, without bias. If an LFT concentrate allows them to be more competitive, we want to provide them that advantage,” said Lee.
