Engineered Plastics Prototyping and Fabrication

LGS offers fabrication solutions for most commercially available plastics, as well as highly engineered specialty materials and composites. Take a look at some of the traits which make engineered plastics and attractive alternative to common materials such as metals, wood and ceramics:

  • Great corrosion and chemical resistance
  • Light-weight, helping to reduce the inertia and centrifugal force
  • Easier and safer to handle
  • Abrasion resistant; minimalizes wear between mating parts
  • Absorbs shock loads that would crack or break metal, as in gear teeth
  • Outlasts other materials
  • Dielectric strength—high performance material at high temperatures with superior electrical properties.

Things to Consider

The following recommended questions can assist you in selecting the best plastic material for your particular application:

  • What requirements does the application have (thickness, size, color, mar resistance, etc.)?
  • To what temperatures will the application be exposed?
  • Will the application be exposed to chemicals or moisture?
  • If used in an electrical design, to what voltages will the application be exposed?
  • Does the material in this application need to resist wear or perform as a bearing?
  • Does the application need to be flexible (able to stretch or bend) or rigid?
Plastic Type Properties Temperature
Acrylic High impact resistance; lightweight; good chemical resistance; excellent weather-ability. 180° F - 200° F
PTFE (Polytetrafluorethylene) Excellent chemical, mechanical and thermal properties; weather resistant; low coefficient of friction 500° F
Nylon Lightweight; high strength-to-weight ratio; abrasion, corrosion and chemically resistant -40° F – 275° F
Polyimide Excellent resistance to high temperature; good chemical resistance; excellent electrical insulation 450° F - 500° F
Polycarbonate High impact strength; high dielectric strength; weather resistant; good chemical resistance

-40° F – 275° F
Polyester Flexible; inert to water; unaffected by oil, grease and aromatics fuels; excellent dielectric -100° F - 300° F
Polyethylene (high density) Excellent corrosion, abrasion, chemical and water resistance; high tensile strength 212° F - 220° F
Polypropylene Excellent forming characteristics; low moisture absorption; resistant to organic solvents 230° F
Polyvinyl Chloride (PVC) Chemically inert; water corrosion and weather resistant; high strength-to-weight ratio -140° F - 170° F
