Abstract
A component such as a siding panel comprised of a PVC/wood flour composite. Another embodiment is a component such as a siding panel that is made from a PVC/CPE/wood flour composite. The cellulosic composite may be extruded through a die and then bent into the shape of the component. Optionally, a reinforcement backer (e.g., an expanded polystyrene foam panel) may be adhered to the cellulosic composite siding.
Claims40
A siding panel made from a composite material, said composite material comprising:
- cellulosic filler in an amount of about 15 to about 35% by weight of said composite material;
- PVC resin in an amount of about 20 to about 70% by weight of said composite material;
- and
- chlorinated polyethylene in an amount not exceeding about 40% by weight of said composite material.
A component made from a composite material, said composite material comprising:
- cellulosic filler in an amount of about 20 to about 30% by weight of said composite material;
- PVC resin in an amount of about 30 to about 60% by weight of said composite material;
- chlorinated polyethylene in an amount of about 5 to about 30% by weight of said composite material;
- and
- inorganic filler in an amount not exceeding about 15% by weight of said composite material.
A component made from a composite material, said composite material comprising:
- cellulosic filler in an amount of about 20 to about 30% by weight of said composite material;
- and
- an alloy in an amount of about 70 to about 80% by weight of said composite material, said alloy comprising PVC and chlorinated polyethylene;
- wherein said chlorinated polyethylene is in an amount of about 5 to about 30% by weight of said composite material.
A component made from a composite material, said composite material comprising:
- cellulosic filler in an amount of about 15 to about 35% by weight of said composite material;
- and
