extrusion machine composite railing ties

Composite Rail Tie - Industrial WoodOur rail ties are proven to last up to four time longer than wood ties in certain environments. composite rail ties key beneficial factors: *Can be installed using same equipment\machines used for traditional wood ties. *Exceptionally long life. *Excellent spike retention. *High compressive strength. *Long life cycle in harsh climates. *High electrical impedance. *Resists rail plate cutting. *Improved gauge retention over the life of the tie. *Reduced Noise and vibration attenuation.

about AXION's Green Technology - Axion Structural InnovationsThis thermoplastic bridge, able to withstand heavy loads with little to no maintenance, expected to last at least 50 years, is no longer the bridge of the future it's the bridge for today. It also meets national environmental goals of being completely recyclable. This technology is not only good for [the Department of Defense], but should be immediately transferred to state departments of transportation for use with short-span bridges wherever possible.

Entrepreneur Puts Mixed-Polymer Recycling On Track to Success ...Polywood Inc. in Edison, N.J., uses mixed recycled plastics to make fiber-reinforced structural profiles for railroad ties, I-beams, and decks. Article Post: ... Rutgers patented its immiscible polymer-blend extrusion process and tried to commercialize it in cooperation with a company that later became U.S. Plastic Lumber. But by ... Kerstein's new company, Polywood, eventually patented its use of the unfilled PE/PS composite for railroad ties and has patents pending on other applications.

Ontario extruder cuts into the market for wood railroad ties ...13 Oct 2015 ... Each wooden tie can leach up to 15 kg of creosote over its lifetime. For this reason, Europe will ban the use of creosote-treated wood rail ties by 2018, and similar legislation in Canada might not be that far off. Which is where Duropar Technologies Inc. comes in. The Brampton, Ont.-based company has developed composite rail ties made entirely from difficult-to-recycle plastic and asphalt wastes, and is on the cusp of bringing the product to market. Duropar got its start ...

They've Been Working on the Railroad : Plastics TechnologyU.S. Plastic Lumber makes ties, marine pilings, wood-filled decking, and other composites. USPL sells ties for both freight and transit, though mainly for transit. It acquired a patented formulation of recycled HDPE plus 10% to 20% short glass from Tri-Max, a maker of pilings that went bankrupt. USPL obtains some plastic flake from its own recycling operations in Chicago and applies the Tri-Max recipes to extruded marine pilings and to molded Dura-Tie RR ties. USPL uses an extrusion ...
