PEI (Ultem®)
Flame-resistant precision engineering with high heat resistance
PEI (Polyetherimide, branded as Ultem®) is an amorphous high-performance thermoplastic combining high strength, inherent flame resistance, and excellent electrical insulation. MK Industrial & Co.® supplies PEI sheets and rods across Bangalore and Karnataka.
About PEI (Ultem®)
PEI (branded as Ultem®) is an amorphous high-performance thermoplastic offering high mechanical strength, inherent flame resistance without additives, and excellent electrical insulation — all while maintaining dimensional stability up to 170°C continuous service. Ultem® is a registered trademark of SABIC.
MK Industrial & Co.® stocks PEI 1000 (unfilled, natural amber) and PEI 2300 (glass-filled) grades in sheets and rods — available in standard dimensions and custom cut-to-size across Bangalore and Karnataka.
PEI is specified across aerospace, automotive, chemical processing, and medical device applications wherever flame resistance, high heat resistance, and electrical insulation are all required at once.
