Amber PEI SHEET for 3D
2 month ago
Product Introduction:
PEI, short for Polyetherimide, is a high-performance thermoplastic engineering plastic with excellent high temperature resistance, high strength, excellent chemical corrosion resistance and dimensional stability. Its molecular structure contains ether bonds and imide rings, which give the material the characteristics of maintaining mechanical properties at high temperatures and is widely used in high-end industrial fields.
Product advantages:
High temperature resistance: continuous use temperature 170°C, short-term resistance above 200°C.
High strength: tensile strength 100-130 MPa, bending modulus 3-4 GPa.
Chemical resistance: resistant to strong acids, strong alkalis, alcohols, ketones and aliphatic hydrocarbons.
Electrical insulation: dielectric strength 16-18 kV/mm, dielectric constant 3.1 (1 MHz).
Low smoke and non-toxic: low smoke and no corrosive gas during combustion, in line with medical and aviation standards.
Easy to process: good fluidity, can be injection molded, extruded, and 3D printed.
Why choose PEI?
Extreme temperature adaptability: suitable for high temperature environments such as aerospace and automobile engine surroundings.
Biocompatibility: FDA certified, can be used for medical implants and food contact equipment.
Lightweight metal replacement: low density (1.27-1.33 g/cm³), reducing component weight.
Long-term stability: fatigue resistance, anti-aging, suitable for precision long-term use parts.
When it comes to high-performance applications, the durability of PEI sheet plays a crucial role. It maintains its physical properties even at elevated temperatures, making it an ideal choice for parts that require long-term exposure to heat. Its ability to withstand repeated sterilization cycles without degradation ensures longevity and reliability in critical environments. For those looking for a material that combines strength, clarity, and thermal resistance, PEI sheet is an excellent option.
PEI sheet is usually a sheet of spring steel with PEI powder sprayed over its surface. And PEI, abbreviation for polyetherimide, is an amorphous, amber-to-transparent thermoplastic with characteristics similar to the related plastic PEEK. Relative to PEEK, PEI is cheaper, but is lower in impact strength and usable temperature. Its strong adhesive properties and chemical stability makes PEI sheet an ideal surface for both FFF and FDM 3D printers. PEI 3D printing is the most easy FDM 3D printing plate.
Industrial applications of PEI sheet extend beyond just 3D printing and medical devices. It is commonly used in electrical insulation, automotive parts, and electronic enclosures due to its excellent dielectric properties and resistance to moisture. In addition, its low flammability and high heat resistance make it suitable for use in environments where safety is a primary concern. The material’s ability to maintain its shape and structure over time ensures that it remains a reliable choice for long-term projects.
