Polyurethane is a thermoplastic so it cuts easily with a hot knife.
Melting temp is around F to F. Avoid breathing the fumes which is the case for any plastic. Cutting Polyurethane Parts.
One of the best machines for cutting urethane parts is a band saw. Long blades of to inches (3, to 4, mm) are desirable because they stay cooler and keep the urethane from melting. A band type we have found to work well is a 4 tooth per inch with raker set. A raker set blade is one that has its teeth alternating to the left and Estimated Reading Time: 1 min.
