MDIthane Series

Conventional polyester elastomers have weak water resistance, and they undergo hydrolysis with temperature and water vapor, resulting in the precipitation of acid, which in turn promotes their hydrolysis. MDIthane modifies the material to enhance its water resistance and environmental adaptability at room temperature, with characteristics such as low moisture absorption, permeability, resistance to steam, water, and seawater.

MDIthane Series

Conventional polyester elastomers have weak water resistance, and they undergo hydrolysis with temperature and water vapor, resulting in the precipitation of acid, which in turn promotes their hydrolysis. MDIthane modifies the material to enhance its water resistance and environmental adaptability at room temperature, with characteristics such as low moisture absorption, permeability, resistance to steam, water, and seawater.
Application

MDIthane is developed on the raw material 4,4 ` - diphenylmethane diisocyanate, which has excellent mechanical and dynamic properties. It has excellent load-bearing capacity, high wear resistance, and outstanding hydrolysis resistance.
