Millathane® Formulary and Grades

Millathane® millable polyurethane rubber comes in a number of Polyester and Polyether grades and subsequent formulary setups.

  • Polyether grades have better water and hydrolysis resistance than polyester grades.
  • Polyester grades have better heat, oil and compression set resistance than polyether grades.
  • Most Millathane grades are available in a range of viscosities and can be packaged as dense bales or premilled sheets.

Millathane® UV

Millathane® UV is an ultra-violet curable millable polyurethane compound typically used with Millathane® 97, but other Grades can be used as well. Millable polyurethane extrusions can be continuously cured and products molded using UV light without the use of ovens, microwaves or salt bath units. (Patent Pending) These curable compounds can be extruded or calendered onto fabric or as an unsupported sheet and then continuously cured by passing them through a UV-curing conveyor belt chamber. Molded parts can be press-cured using special transparent molds to allow curing with UV light, or can be cured in a UV chamber. Time of irradiation varies with the nature and type of material, the type and concentration of other ingredients, and the type and power of the light source. They are great for extruding hollow tubing and other continuous shapes, such as bars, rods, L-channels, U-channels, square tubing, and the like.  It’s great for extruded protective covering over all types of cables, hoses, and protective conduit. Contact us for more information if you are interested in using this alternative curing system.
