Rohm and Haas Co. has introduced to North America an impact modifier that boosts extruded vinyl processability and output.
Paraloid KM-348 is a high-efficiency, all-acrylic modifier, according to the Philadelphia company. Processing is improved through lower melt temperatures, lower die pressures and reduced torque, thus easing strain on the extruder motor.
Rohm and Haas claimed the new modifier matches or beats competing products when used at 20 percent lower addition levels. It is geared to weatherable extrusions.
