  • Durable plastic fencing
    Patent number: 9079336
    Abstract: Durable post and rail fencing comprises polyolefin posts and rails having a nominal diameter greater than 2.5 inches and a flexural modulus at 40° F. of at least 110,000 psi. Such rails and posts produced by extrusion through a circular die to a heat transfer medium to provide a log-like shape.
    Type: Grant

  • Plastic logs
    Publication number: 20040091644
    Abstract: Plastic logs having a smooth, textured, glossy surface with a nominal diameter greater than 2 inches and a flexural modulus at 40° F. of at least 70,000 psi. Thermoplastic material comprising such logs is preferably substantially polyolefin and other plastic materials having a higher melt temperature, e.g. a melt temperature at least 20° C. higher than the melt temperature of the polyolefin component. Such logs are produced by extrusion through a circular die to a heat transfer medium. Such extruded logs are especially useful for durable fencing.
