srg plastics specializes in custom plastic profile extrusion

 

Plastic profile extrusion  produces a part that has a continuous
cross-section such as a tube or channel. Using heat up to 600
degrees F and pressure the profile is pulled at a specified line
speed through a machined set of dies and calibrators that
match the part dimensions.

Profile extrusion materials offered

  • PVC  available in rigid, semi-rigid and flexible (often referred to as vinyl)                               
  • Acrylic  excellent clarity and hardness used in retail display
  • ABS  considered an engineering grade exhibits good impact properties
  • Polycarbonate  has excellent strength (usually referred to as Lexan)
  • Styrene  is an economical choice for clear applications
  • Polyethylene  excellent impact strength and lubricity
  • Polypropylene  good durability and used in toys and consumer items
  • PETG  similar to acrylic and not as prone to fracturing
  • TPE and TPR  elastomers that exhibit natural rubber

Physical properties of custom extrusion plastics

Materials can be enhanced to:

  • increase impact strength
  • resist ultra violet exposure
  • resist cold for outdoor application
  • resist extreme heat
  • withstand harsh chemicals
  • Meet FR requirements


Material additives:

  • high gloss – semi gloss – matte finishes
  • anti-stat for electronics
  • stock colors
  • custom colors
  • foaming agent to reduce weight
  • fungicide agent for mold control
