TSE Industries launches its new Millathane UV, a UV-curable millable polyurethane compound.
For the first time ever, millable polyurethane extrusions can be continuously cured, and products molded, using UV light without the use of ovens, microwaves or salt bath units.
Millathane UV curable compounds can be extruded or calendered, onto fabric or as 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.
Millathane UV can be used for extruding hollow tubing and other continuous shapes, such as bars, rods, L-channels, U-channels, square tubing, and the like. Physical properties are similar for UV and peroxide cured compounds. Typical compounds are in the 60-80 Shore A range, but higher and lower hardnesses will be available.
