en.Wedoany.com Reported - Struktol USA has introduced the VMO series of melt flow modifiers, designed to help polypropylene processors boost production efficiency while meeting sustainability goals. The series utilizes a patented combination of fatty acid derivatives and chain scission technology to rapidly and precisely adjust the melt flow index (MFI), enabling increased throughput and cost reduction at low addition levels.
The VMO series comprises five activity grades—VMO 058, 108, 208, 308, and 408—each tailored to different melt flow targets and processing requirements. The series is supplied in off-white to beige pastille form and incorporates an odor neutralizer to reduce the smell of the finished compound. The masterbatch format facilitates precise addition in extrusion, compounding, and injection molding processes. The products are compatible with polypropylene containing up to 35% polyethylene (PE), maintaining stable performance in both virgin and recycled material applications, thereby supporting the circular economy and closed-loop recycling.
The drop points of the various grades range from 74°C to 86°C, with a specific gravity of 0.98 to 1.0, and a shelf life of no less than two years. Packaging options include industry-standard 50-pound bags and 2000-pound pallet packs. Struktol provides accompanying technical service, research and development, and quality assurance support to help processors achieve the optimal balance of efficiency and quality.
Furthermore, as reported by PlasticsToday in November 2025, Struktol also launched two specialty additives, RP 17 and RP 53, specifically designed to address odor issues in recycled plastics, meeting the growing demand for higher recycled content in plastic products. RP 17 also functions as a processing lubricant and mold release agent, reducing buildup and the frequency of equipment cleaning; both products help improve filler dispersion, shorten mixing times, and enhance surface finish and physical properties.
Struktol is part of the Schill+Seilacher Group, operating in over 100 countries worldwide, specializing in additives for natural rubber, synthetic rubber, plastics, and wood-plastic composites.
