New Structural Thermoplastic from RTP Company Fills Performance Gap

RTP has developed new RTP 100 eXtra Performance (XP) Compounds, a series of thermoplastic compounds formulated for higher strength, modulus and impact properties than any standard chopped fibreglass polypropylene (PP) compounds available on the market today.

With strength, stiffness, and impact resistance performance that is close to RTP’s Very Long Fibre (VLF) compounds, combined with the lighter weight and chemical resistance of standard PP compounds, RTP says its 100 XP Compounds provide a new realm of design possibilities for applications in the automotive, furniture, appliance, storage, industrial/construction, electronics, and energy markets.

According to RTP, the comparison to common glass fibre reinforced PP at similar load levels, RTP 100 XP Compounds exhibit up to 20% higher modulus values and twice the impact resistance. Their lighter density makes RTP 100 XP compounds an ideal choice for “lightweighting”, the process of reducing the overall weight of an application by replacing heavier metal components with lighter weight thermoplastic compounds. Due to their inherent chemical resistant properties and non-hygroscopic nature, RTP 100 XP Compounds are also an excellent alternative to nylon or other compounds where moisture can reduce load bearing capabilities.

RTP 100 XP Compounds are available from RTP Company worldwide as standard pellets in formulations containing from 10-50 weight % glass fibre reinforcement, and can be easily injection moulded into large or small complex geometries. Additionally, it says, additive technologies may be incorporated to create robust compounds, engineered to meet demanding requirements such as long term heat aging, cold weather impact resistance, flame retardance, ultra violet protection, or compliance with government agency approvals.
