Nylon
Strong, wear-resistant engineering plastic with moisture absorption and broad molding use.
Engineering Plastics Selection Guide
Choose an engineering plastic around load, temperature, and environment.
Compare polymer family, strength, stiffness, wear, temperature, chemicals, moisture absorption, electrical behavior, dimensional stability, processing, and cost.
Buying Overview
Start with the complete application requirement.
Engineering plastics can replace metals in applications requiring low weight, corrosion resistance, electrical insulation, wear performance, low friction, chemical resistance, or complex molded geometry. Selection must account for temperature, time under load, creep, moisture, UV, chemicals, tolerances, flammability, additives, and manufacturing method.
Comparison Criteria
Technical and supplier factors to review.
Use consistent criteria across suppliers and options so recommendations, quotes, and risks can be compared on the same basis.
Acetal
Dimensionally stable, low-friction plastic suited to precision components, gears, and mechanisms.
Polycarbonate
Tough, transparent polymer with high impact resistance and useful temperature performance.
UHMW Polyethylene
Low-friction, impact-resistant material commonly used for wear strips, liners, and guides.
PEEK
High-performance polymer offering heat, chemical, wear, and mechanical capability.
PTFE
Fluoropolymer known for chemical resistance, low friction, electrical insulation, and temperature range.
PPS and High-Heat Plastics
Materials selected for dimensional stability, chemicals, flame resistance, and elevated temperature.
Filled and Reinforced Grades
Glass, carbon, mineral, lubricant, conductive, and flame-retardant modifications.
RFQ and Specification Details
Provide enough information for an accurate recommendation.
Mechanical Load
Define tensile, compressive, bearing, impact, fatigue, creep, and wear requirements.
Temperature Profile
Include continuous temperature, peaks, cycling, heat aging, and thermal expansion.
Chemical Exposure
Identify fuels, oils, cleaners, acids, alkalis, moisture, steam, and sterilization.
Dimensional Requirements
Specify tolerance, moisture conditioning, creep, shrinkage, flatness, and stability.
Electrical and Fire Performance
Include insulation, dielectric strength, conductivity, static control, and flammability.
Processing Method
Clarify machining, injection molding, extrusion, thermoforming, welding, or additive manufacturing.
Selection Workflow
A practical path from requirements to approval.
Define the complete environment
Document load, temperature, chemicals, moisture, UV, wear, electricity, and fire requirements.
Screen polymer families
Eliminate materials that fail temperature, chemical, mechanical, or regulatory needs.
Account for time and moisture
Review creep, stress relaxation, conditioning, dimensional change, and long-term aging.
Match the processing method
Confirm machinability, moldability, shrinkage, warpage, tooling, joining, and finishing.
Validate with representative testing
Use prototypes, conditioned samples, load testing, chemical exposure, and dimensional checks.
