Abstract: A method for producing environmentally friendly, mono-extruded hemp composite board (EHB) is provided. By using hemp fiber and hemp hurd in combination with virgin and/or recycled binders, the system and method may be used to create preferable substitutes for traditional construction boards. The method generally comprises steps of processing hemp hurd/fiber and injecting said hemp hurd/fiber into an extruder along with a binder. Waste products from other production streams may be added as well to reduce waste/cost of said production streams. The resulting EHB is structurally superior to traditional construction boards largely due to the structural characteristics of dispersed hemp hurd and hemp fiber, their complete encapsulation in a binder material, and their lower hygroscopic properties. Additionally, since the EHB is created using an extruder, a downstream extrusion arrangement may be used to mold the EHB into shapes that are difficult to achieve with traditional construction boards.

Another aspect relates to a polyolefin-based foam sheet constituted of a 4-methyl-1-pentene-based polymer, in which the difference in Shore A hardness of at least one surface at different times is defined. A further aspect relates to a complex including a foam body constituted of a 4-methyl-1-pentene-based polymer and a member which is bonded to the foam body and is different from the foam body.
