The nucleating system includes a combination of an inorganic crystalline compound and an aromatic amide oligomer. The present inventors have discovered that the combination of these different types of nucleating agents result in excellent crystallization properties (e.g., rate of crystallization). Due to the improved crystallization rate, the thermoplastic composition can be molded at lower temperatures to still achieve the same degree of crystallization. In addition to minimizing the energy requirements of the molding operating, the use of lower temperatures can also decrease the production of “flash” normally associated with high temperature molding operations. The composition may also possess good viscosity properties that allow it to be readily molded into parts of a variety of different shapes and sizes.

  • Patent number: 8894901
    Abstract: A method of making a sheet of building material, useful for roofing or siding applications, and the sheet material made by such method. A mixture of a thermoplastic resin and mineral filler is prepared, the resin comprising about 10% to 40% by weight of the mixture and the filler comprising about 60% to 90% by weight. The mixture is mixed at a temperature above the melting point of the resin and is formed into a sheet at such temperature. The sheet is allowed to cool until the surface is at a temperature below the midpoint of the melting range of the thermoplastic resin, e.g. in the range of 210 to 220 degrees F. (99 to 104 degrees C.), for polyethylene, at which point it is strained by passing it through calendering rollers. The sheet material made by this process, having a high concentration of mineral filler, is fire resistant, durable, ductile, of moderate weight and resistant to weathering. It can be produced using relatively inexpensive manufacturing equipment.
