Comparing materials for custom plastic extrusions

Both engineered and standard plastic materials can be developed to meet many needs. These include operating temperatures, UV resistance, coloration or opacity, flame resistance, rigidity and more.

Plastic compounds can produce extremely rigid profiles or mimic the physical properties of rubber. Below is a brief comparison of commonly used materials .  For more information on plastic materials as well as custom profile extrusion design, download our Intro to Designing Extruded Plastic Profiles.

 TPE (Thermoplastic Elastomer) 

  • Combines the look, feel, and elasticity of conventional rubber with the processing efficiency of plastics.
  • A wide range of durometers
  • Low compression set
  • High elongation
 
PVC (Rigid)
  • Tough and economical
  • Flame retardant
  • Resistant to most chemicals
  • Offered in clear, opaque, weather resistant, high tensile strength, and impact resistant formulations
  • Easily machined
 
PVC (Flexible)
  • Rubbery soft to semi-rigid
  • Abrasion-resistant
  • Good insulation properties
  • Commonly used for impact resistant bumpers, weather stripping and tubing
 
HIPS (High-Impact Polystyrene)
  • Rigid
  • Economical
  • Light-weight
  • Flat finish
  • Translucent white, standard and custom colors
 
ABS (Acrylonitrile Butadiene Styrene)
  • Versatile
  • Rigid
  • High impact resistance
  • Good chemical resistance to non-aromatic compounds
  • Best used in indoor applications
 
ASA (Acrylonitrile Styrene Acrylate)
  • Tough and rigid
  • Good chemical resistance
  • Thermal stability
  • Outstanding resistance to weather, aging and yellowing
  • High-gloss
 
EPP/EPE (Expanded Polypropylene/Polyethylene)
  • Eco-friendly
  • Flexible
  • Used for lightweight, energy management and cushioning applications
 
Polypropylene
  • Semi-rigid
  • Light-weight
  • Economical
  • Excellent chemical resistance
  • High service temperature
