What types of thermal plastics can be used in Profile Extrusion?

H.D.Plastics is a premier supplier and exporter for custom Profile extrusion

The manufacturing process is including:

  1. Plastic extrusion: Plastic is heated and pushed through a heated chamber by a screw.
  2. Molding: Plastic is forced through a die that creates the final shape of the part.
  3. Cooling: The extruded plastic is cooled.
  4. Cut or spool: The continuous shape is spooled or cut into lengths.

The most common thermoplastic polymer can be used in profile extrusion as below:

  • Acrylic (PMMA)
  • Acrylonitrile butadiene styrene (ABS)
  • Polyamide (PA)
  • Polystyrene (PS)
  • Polycarbonate (PC)
  • Polypropylene (PP)
  • Polyethylene (PE)
  • Polyvinyl chloride (PVC)

The widely popular choices are PE, rigid and flexible PVC, HIPS, PS, and ABS. These resins offer a wide range of properties and are relatively low cost in comparison to the engineering resin grades.

Rigid PVC extrusion has good color stability, is a low cost, has good toughness and durability, and is used in many outdoor applications in building and construction.

Flexible PVC  is clear, tough, and flexible and mostly used in tubing, gaskets, and seals.

Polyethylene is a low cost, flexible, and can be coiled and cut to length in filled applications.

The attributes of each polymeric grade determine which material to use in different extrusion profile applications.  Using the proper extrusion processing conditions with the correct resin viscosity allows virtually all resins to be used in profile extrusion.

We are a leading manufacturer of Flexible PVC (Polyvinyl Chloride) plastic profile extrusion products. The profiles are extremely flexible, lightweight, and clear, and can be cut to your specific length.
