Abstract: Disclosed herein is a method of producing a film, the method being capable of suppressing formation of die lines in melt extrusion molding using a T die. A thermoplastic resin composition having a relaxation modulus of not less than 100 Pa and not more than 2,000 Pa is melted and kneaded, the relaxation modulus being measured under conditions of a temperature of 260° C., distortion of 1%, and a relaxation time of 1 second, and extrusion molding of the thermoplastic resin composition using the T die is performed to form the film. The thermoplastic resin composition may contain an acrylic resin and a rubber particle.

Abstract: A hollow paving block comprises a substantially planar member having a first surface and a second surface opposite the first surface. The first surface of the planar member is a textured surface which functions as a top of the paving block. A side wall extends along and away from a periphery of the second surface of the planar member to define a cavity in the paving block. The side wall has a beveled edge which extends about a mouth of the cavity. At least one protrusion extends along the second surface of the planar member. The paving block is formed in part from crumb rubber and polyolefin.

Abstract: Various embodiments provide surface compositions and methods for porous, flexible, and durable surfaces that may stabilize native soil, provide substantially uniform drainage of moisture, and provide a barrier between the native soil, vegetation, and other compositions disposed over the surface composition, such as sand and/or soil. The compositions and methods may comprise utilizing a liquid coating composition, liquid binder, and/or antimicrobial composition in combination with a particulate material configured to provide a desired pore size, elasticity, compression, and/or stability to the surface composition. Various embodiments of the surface composition may form a prefabricated flexible bunker liner for application to the native soil in a golf course bunker beneath sand.
