An oriented polymer composition (OPC) article comprising a body having a length, which is greater than any perpendicular dimension, comprised of an OPC having a softening temperature, the body having an outer surface extending the length of the body, having polymer strands aligned in the lengthwise direction of the body, wherein the length dimension stability is greater than 99% when tested by heating the article for 24 hours at temperatures at least up to and including 71 degrees Celsius after completion of the manufacture of the article and processes for forming said article.

Plastics-based manufactured article and processes for forming said article

An oriented plastic composition (OPC) shaped article having a length, width and thickness dimension in which the width and thickness dimensions are less than that of the length dimension, having at least one surface that can be machined so that a portion of the OPC shaped article is reduced in the width or thickness dimension along at least a portion of the length of the article and a process for making and machining an OPC shaped article.

Plastics-based manufactured article and process for forming

Solid state draw a laminated polymer billet containing two or more polymer compositions laminated to one another to prepare an oriented polymer composition.

Solid state drawing laminated polymer billets

A building product and method for manufacturing a building product made from an oriented polymer composition which can be split to provide a surface of the building product with a plurality of visible fibrils to form an aesthetic representative of split wood.

Building product and method of manufacture and use

Draw a polymer composition by providing a polymer composition containing an orientable polymer having a softening temperature and a filler; conditioning the temperature of the polymer composition at or below its softening temperature; and drawing the polymer composition at a draw rate of at least 127 centimeters per minute in order to achieve an oriented filled polymer composition demonstrating a stable extent of cavitation with draw rate.

Solid state drawing a filled polymer composition to a stable extent of cavitation and density

Prepare an oriented polymer composition that is cavitated, has cross sectional dimensions all at least three millimeters and at least one de-oriented surface layer having a thickness of at least 80 microns and at least 50 microns less than half the thickness of the oriented polymer composition, the de-oriented surface layer having a lower degree of polymer orientation than a 100 micron thick portion of the oriented polymer composition adjacent to and below the de-oriented surface layer by sufficiently heat treating a surface of a cavitated oriented polymer composition.

Oriented polymer composition with a deoriented surface layer

Including crosslinked rubber particles in an oriented polymer composition induces cavitation in the oriented polymer composition and can increases the scratch and mar resistance as well as fibrillation resistance.

Rubber filled oriented polymer composition article

An oriented polymer composition containing thirty to 95 weight-percent inert inorganic filler and a continuous phase of at least one orientable polymer contains void spaces due to cavitation and has a density of less than 0.8 grams per cubic centimeter, a flexural modulus of 1.4 gigapascals or more, cross section dimensions all greater than 1.5 millimeters, a delamination force value of 44.5 Newtons (ten pounds force) or more and little or no blowing agent.

Low density oriented polymer composition with inert inorganic filler

An inventive solid state drawing die has shaping walls that define a shaping channel and that, in the course of solid state drawing, direct polymer composition along a drawing path. Each cross section of the drawing path (and, hence, polymer composition in the drawing path) is non-circular, substantially proportional to one another, contains a centroid that lies on a substantially straight line parallel to the drawing direction and all cross sectional dimensions are 1.5 millimeters or more.
