One of our recent solutions has been replacing UHMW L-shaped channel for chain runs in OSB mills with Redwood Plastics and Rubber Redco 750 polyurethane. The issue is that the chain creates too much heat on the UHMW plastic warping it and causing it to bubble. Redco 750 bears more load and its properties appear to dissipate the heat better resulting in a solution to the problem.
These channels can be manufactured in virtually every desired profile, though a one-time set up fee would be required for a profile with new dimensions. Once the tooling is done, shipments can be made in the reasonable time frame of typically 3 weeks. The material is flexible, yet strong, and resilient to abrasion and wear as well as carrying up to 2500 PSI of load.
