RTP Company is introducing the new light and tough LT Compounds, a series of thermoplastic compounds said to weigh 5-10% less than typical filled compounds, but with equivalent mechanical properties and similar shrinkage values.
According to the company, LT Compounds are the fastest and easiest way to accomplish weight reductions in parts moulded with glass fibre reinforcement without compromising performance or requiring modifications to existing tools.
“Our LT Compounds can be drop-in replacements without the cost burden associated with other options to reduce weight,” explains Jason Kafader, Structural Product Manager at RTP.
Unlike chemical foaming agents, the density reduction provided by LT Compounds is not dependent on wall thickness, RTP reports, and furthermore, aesthetically pleasing parts are achievable, which is not always the case with chemical foaming. Since LT Compounds are often able to be used as a drop-in solution with existing tooling, the switch from other materials can be a smooth and economical transition.
“LT Compounds from RTP Company are best used as lightweight alternatives when the goal is to minimise energy consumption or the amount of human effort required to use the part, says Kafader. “This makes them an ideal material for handheld, battery-operated tools, sporting goods, handheld appliances, recreational vehicles, and other common markets for glass fibre reinforced compounds that will benefit from reductions in weight.”
