Material Notes:
MILLATHANE CM is a sulfur and peroxide curable polyether urethane rubber. Its outstanding property is its great resistance to abrasion, which makes it of special interest for articles that are subjected to high wear in service. It has a unique combination of excellent properties, such as low temperature characteristics, and resistance to heat deterioration, ozone cracking, weathering and swelling in oils or solvents.An activator containing zinc should be used to insure faster rates of cure in reasonable periods of time. Zinc diethyldithiocarbamate and zinc dibutyldithiocarbamate over the range of 0.1 to 1.0 phr have been used, but they do not give cures as satisfactory as the ZnCl2/MBTS complex known as CAYTUR 4.FormulationMillathane CM 100.0N330 Carbon Black30.0Coumarone-Indene Resin15.0MBTS4.0MBT1.0Sulfur0.75CAYTUR 40.20Zinc Stearate0.5All information provided by TSE Industries
