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, while 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.

To be compliant with the FDA regulation 21CFR 177.2600, articles made must be made from the lists of ingredients shown in that section of the Federal Register. Additionally, if the article will come in contact with aqueous or oily foods, water or hexane extractions, respectively, need to be done on the finished article. TSE Industries, Inc. makes no guarantees that the end article complies with any part of the United States Code of Federal Regulations. All testing, registrations, and final approvals must be made by the article’s manufacturer.
Millathane® E40 is a sulfur or peroxide curable polyether polyurethane rubber for the production of rollers, belts seals, gaskets, and other molded parts that require excellent abrasion resistance, low-temperature performance, hydrolytic stability, and high mechanical strength.
Millathane® 66 is a peroxide curable urethane rubber for the production of oil, fuel, and chemical resistant parts which require excellent low and high-temperature performance and high mechanical strength. Compounds of this compound have excellent abrasion resistance. Premilled contains 1.5 phr of a polycarbodiimide (Millstab™ P) as a stabilizer for improved hydrolysis resistance and heat aging properties.
Millathane® 55 is a high-performing polyether millable urethane rubber developed primarily for applications requiring low viscosity, high hardness sulfur-cured compounds. Compared with Millathane E34 in sulfur cured compounds, Millathane 55 compounds have higher hardness but with lower viscosity. Compounds also have excellent abrasion resistance, high resilience (rebound), excellent ozone resistance, moderate oil and fuel resistance, and very good hydrolytic stability. It is sold in bales, not pellets, for ease of processing on rubber mills.
Millathane® 76 is a polyester millable urethane having improved processing properties over a wide Mooney viscosity range. It has excellent damping properties that are useful in vibration control for automotive applications. O-rings, seals, and gaskets are often made from this compound because of its excellent oil and fuel resistance. It is comparable to nitrile in oil and fuel resistance but has better low-temperature properties and excellent ozone resistance.
Millathane® 76 can be used to replace conventional elastomers like natural rubber, nitrile, and EPDM. It possesses excellent abrasion resistance combined with toughness, low-temperature flexibility, ozone resistance, good damping, high tear strength, and good stress relaxation properties. It is a suitable choice in applications such as bushings, small copier rolls and bumpers, o-rings, hydraulic seals, belts, and solid tires.
Millathane® 97 is designed for applications in shoe soling, roll coverings, and other applications where transparency in brightly colored or decorative products is required. It’s a polyether millable urethane rubber having excellent wear properties, a high coefficient of friction, and very good UV stability.
Millathane® 5004 is a peroxide curable polyester millable urethane rubber. It has excellent processing characteristics and can be injection molded easily. In addition to excellent abrasion resistance, it has the highest stress-strain values of all peroxide cured polyurethanes. The cured stock has excellent tear strength, excellent low-temperature flexibility, and resistance to oxygen, ozone, fuels, and oils.
Millathane® CM is a sulfur or peroxide curable polyether millable polyurethane rubber with excellent physical properties and abrasion resistance. It also has good oil resistance and excellent low-temperature properties and is used for molded articles, rollers, and military and aircraft applications.
Millathane® E34 is a high-performance polyether millable urethane rubber that has been developed for applications requiring high abrasion resistance, low-temperature flexibility, ozone resistance, oil and fuel resistance, outstanding hydrolytic stability, and improved processing. The compound also has high resilience (high rebound) characteristics.

Millathane® HT Premilled
Millathane® HT is a polyester millable polyurethane that has excellent frictional properties for applications like rollers for paper handling. It can be processed and cured by use of conventional rubber manufacturing equipment and techniques to yield finished urethane rubber parts. Compounds prepared from Millathane® HT can be vulcanized with either sulfur or organic peroxide-based systems. It has excellent frictional characteristics with good heat aging and low-temperature flexibility. It also features a high abrasion resistance, excellent ozone, and weathering resistance, and good oil and fuel resistance. Millathane® HT Premilled contains 1.5 phr of a polycarbodiimide hydrolysis stabilizer (Millstab™ P).
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.
