Stable machining grades of polyolefin stock shapes.
The new series of Stable Machining Grade (SMG) materials from Quadrant Engineering Plastic Products (Quadrant EPP), Reading, Pa., was developed to improve the performance and productivity of parts machined from polyolefin stock shapes. Several products based on in-house R&D are to be launched in March and June. Each of these materials reportedly stretches the boundaries for machinable shapes manufactured from PP and PE.
The new materials each boast a special performance characteristic, such as dimensional stability, higher temperature resistance, or enhanced purity. Each formulation was developed based on market feedback--some of it segment-specific--that helped researchers better understand the problems end users were having with existing polyolefin formulations.
