What types of materials does MPC use to develop custom formulations?
Most of the diisocyanate prepolymers or quasi-prepolymers we use, including MDI, TDI, PPDI, TODI, NDI, and HDI, are acquired from Fortune 500 suppliers. These prepolymers or quasi prepolymers are used in combination with MPC’s patented and proprietary curative mixtures of polyols, extenders, and cross linkers, with/without conductive additives, to meet specifications and achieve optimal performance. The isocyanate concentration (NCO) in prepolymers used in compounding is measured several times a day. The ratios for prepolymer (Part A) and curative (Part B) are computer-controlled on a metering machine for flow rate, temperature, and de-molding time to ensure the accurate stoichiometry during production. This results in urethane parts that possess consistent physical and mechanical properties. Casting products include solid and foam (open /close cell) in semi-conductive or insulating urethanes required by different industrial applications. The hardness of the solid roller, rod, wheels,
