Structural thermoplastic addresses a performance gap
RTP
The new RTP 100 eExtra Performance (XP) Compounds (photo) are thermoplastic compounds that are formulated for higher strength, modulus and impact properties than any standard chopped-fiberglass polypropylene (PP) compounds available in the market today, says the manufacturer. With strength, stiffness and impact resistance performance that is close to the company’s Very Long Fiber (VLF) compounds, the RTP 100 XP Compounds also enjoy the lighter weight and chemical resistance of standard PP compounds. This helps to expand the range of opportunities in industrial and commercial applications. For instance, compared to common glass-fiber-reinforced PP at similar loads, the inherently chemical resistant and non-hygroscopic RTP 100 XP Compounds exhibit up to 20% higher modulus values and twice the impact resistance, says the company, and their lighter density makes these compounds well-suited for applications where lower weight is desired. The RTP 100 XP Compounds are available as standard pellets in formulations containing from 10–50 wt.% glass fiber reinforcements, and can be easily injection molded into large or small complex geometries. Additives can be incorporated to meet other demanding requirements of the application.— RTP Co., Winona, Minn.
