Major, which recently introduced an advanced polyurethane (PU) strip variant to the Flex-Mat Modular series, is showcasing its new development at AGG1 Aggregates Academy & Expo.
The new variant, which offers increased durability and extends media lifespan and effectiveness in wet and corrosive environments, is being highlighted March 25-27 in Booth 1809 at America’s Center Convention Complex in St. Louis.
“While most screen media provide excellent durability, we noticed accelerated wear in some corrosive applications,” says Kevin Laporte, R&D manager at Major. “We immediately began testing to create a corrosive-resistant alternative we could develop into a new polyurethane variant. The new polyurethane strips would allow these specialty operations to benefit from Flex-Mat’s productivity-boosting qualities while still maximizing uptime.”
According to Major, the advanced polyurethane strip features greater chemical stability to improve performance in alkaline, acidic and wet environments such as limestone operations. The company says advanced durability extends the overall wear life of screen media in applications where polyurethane strips typically wear out before the steel wire, affecting the integrity of screen media.
Like Major’s standard polyurethane composition, the advanced polyurethane strips are available for the Flex-Mat Modular D, S and T series. Major says the new variant is not intended to completely replace the standard polyurethane.
“The advanced PU strips aren’t meant as a complete replacement for standard polyurethane,” says Ian Edwards, vice president responsible for global sales at Major. “Instead, they’re a special-order option for screen media going into harsh environments. The best use of the advanced PU strips is when operations are screening corrosive or wet materials or when the operation notices their polyurethane is breaking down faster than the steel wire. In most cases, the standard polyurethane strip option continues to perform optimally for our customers.”
