Injection Molding Materials
Choosing the right injection molding material can make or break your project. Our comprehensive guide helps you quickly compare options based on strength, flexibility, and heat resistance, so you can confidently select the ideal material for prototypes, production parts, or custom designs—ensuring high-quality results every time.
PEI
Type: PEI
Temperature Resistance, Strength, CorrosionResistant, Flame Retardancy, Electrical Insulation, Aging Resistance
PEI (polyetherimide) is a high-performance thermoplastic engineering plastic that combines excellent heat resistance, mechanical properties, and chemical stability, enabling it to be widely used in high-end industrial fields such as aerospace, electronics and electrical engineering, and medical equipment.
PTFE
Type: PTFE
Temperature Resistance, Corrosion Resistance, low friction Coefficient, Aging Resistance
Polytetrafluoroethylene (PTFE), commonly known as Teflon, is a high-performance fluoropolymer. It is frequently used in mechanical components requiring reduced friction and wear—such as bearings, gears, and piston rings—due to its non-stick properties, low friction characteristics, and self-lubricating capabilities. PTFE also exhibits excellent electrical insulation properties, making it highly suitable for applications like high-frequency cables, high-voltage insulators, and electronic components.
Additionally, PTFE maintains stable performance during long-term use across an extreme temperature range from -200°C (ultra-low temperature) to 260°C (high temperature), enabling its use in harsh environments such as aerospace systems, deep-sea equipment, and high-temperature industrial apparatus.
