    • Polyimide (PI)

Common Materials

  • Polyethylene (PE): Versatile and cost-effective, used in packaging and containers.
  • Polypropylene (PP): Durable with good chemical resistance, ideal for automotive and consumer goods.
  • Acrylonitrile Butadiene Styrene (ABS): Strong and impact-resistant, commonly used in electronics and automotive parts.
  • Polyoxymethylene (POM): High stiffness and low friction, suitable for precision components.
  • Polystyrene (PS): Lightweight and easy to mold, used in disposable items and packaging.​

Material Selection Considerations

When choosing a material, consider:

  • Mechanical Properties: Strength, flexibility, and durability.
  • Thermal Properties: Operating temperature range and heat resistance.
  • Chemical Resistance: Exposure to solvents, acids, or bases.
  • Aesthetic Requirements: Color, transparency, and surface finish.
  • Regulatory Compliance: Food-grade, medical-grade, or flame-retardant standards.​
