MPC carries Developer rollers, PCR rollers and Adder rollers for the most demanding print applications. MPC can develop formulations to meet OEM applications and specific remanufacturer requirements. MPC has responded to the needs of those remanufacturers providing Managed Print Service dealers with commonly used Lexmark and HP parts. Using our expertise in conductive polyurethane chemistry, MPC has developed a superior quality line of polyurethane laser print developer rollers for both monochrome and color print engines. The monochrome line includes a roller for the Lexmark S&T series inclusive of the T640, T520, T620, T630, T640, T650, E260, E360 and E460 series and other compatible systems. For HP color printers, MPC currently provides replacement urethane rollers for the HP4600, HP5500, HP3500 and HP3700 series.

Conductive polyurethanes can be custom-formulated for semi-conductivity ranging from E7 ohm-cm to E9 ohm-cm. Semi-conductivity levels as high as E5 ohm-cm can be achieved with special formulation. These conductive formulations use very low percentages of proprietary additives to control semi-conductivity uniformly throughout the product. Using only small amounts of these additives preserves the strength, resilience, thermal stability, and service life of the original polyurethane. Characteristics Very uniform electrical conductivity Low conductant loading Low conductant migration Negligible loss of urethane physical properties Applications Both conductive solid urethane and conductive urethane foam are widely used in office and paper handling machines including copiers, thermal printers, and laser printers. Conductive urethane is ideally suited for laser printer charge and developer rollers for toner dispensing and tribocharge management, and is also used in paper transport assemblies for copiers, fax machines, collators, postage meters, and other transport applications where static build-up is a problem. It can provide ESD protection in agricultural, mining, and materials-handling applications such as drive and conveyor belting, tank and bin liners, and hose and tubing. Other applications include antistatic drive belts for silicon wafer transport in clean rooms, and wheels and rollers for transport in static-sensitive environments.

Cellular Urethane Foam Cellular foam is chemically-blown, closed-cell urethane foam. MPC can formulate this foam to meet various physical properties (coefficient of friction, abrasion resistance, hardness and density) to suit your application. The rebound can be formulated for resiliency or energy absorption. Belts Features Replicates performance of solid, with flexibility of foam Excellent shock absorption and resiliency Chemically blown Self-cleaning, non-glazing Larger, less uniform cell structure than Microcellular Foam High tear strength and tensile modulus Applications Applications for cellular foam include self-cleaning paper feed rollers, retard pads, conveyor belts, bumpers, shock absorbers and timing belts. Note: Can be foamed over solid foam to modify the outer layer of a timing belt to add media transport to the toothed timing function.
