    Low temp use of Polyethylene/polyproylene

    Harry; Thanks for the info.The enclosure is approx. 8 x 18" with the living hinge at the top. We tried std. pp and the hinge worked fine as long as you perform the recommended flexing operation after molding. Cold temp on the pp though stinks. We are now trying HDPE, MDPE. Rdgs Tom

    Low temp use of Polyethylene/polyproylene

    We are designing a telecommunications closure for outdoor use. The design calls for a living hinge and impact requirements at -20c. Does anyone know of of material in the polyproylene/polyethylene family that will sustain such conditions?
