MAJOR’s PU strip designed for durability in wet or corrosive screening environments
The new polyurethane strip variant boosts the lifespan of the FLEX-MAT Modular series
MAJOR, a manufacturer of wire screen media, has introduced a polyurethane (PU) strip variant for the FLEX-MAT Modular series. The new variant is designed with greater chemical stability to increase the screen media's durability and effectiveness in wet and corrosive environments such as limestone operations.
"While most screen media provide excellent durability, we noticed accelerated wear in some corrosive applications," says Kevin Laporte, MAJOR research and development manager. "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."
The advanced durability extends the overall wear life of screen media in applications where the PU strips typically wear out before the steel wire and affect the integrity of the screen media.
Designed for challenging environments
FLEX-MAT's OPTIMUMWIRE bonds to MAJOR's distinctive lime green PU strips to offer higher wire vibration than woven wire screen media. The unique chemical compound holds up well against corrosive materials to ensure the strips match the lifespan of OPTIMUMWIRE and maintain screening integrity up to 10 times longer, according to the company. The new durability of the PU strips still allows the same flexibility as the standard option so the wires can vibrate freely.
Like MAJOR's standard polyurethane composition, the advanced PU strips are available for the FLEX-MAT Modular D, S and T Series. The new variant is not intended to completely replace the standard polyurethane.
A special order option
"The advanced PU strips aren't meant as a complete replacement for standard polyurethane. Instead, they're a special-order option for screen media going into harsh environments," Edwards says. "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."
All FLEX-MAT screen media feature the company's signature FLEX-MAT ID-enabled technology with an RFID tag embedded in the frame. This technology allows users to easily access product information by scanning the RFID chip with The MAJOR App.
