Polyetherimide (Glass Filled) Specifications

Description

An amorphous thermoplastic Polyetherimide, stock shapes from this resin possess a combination of useful characteristics, including high strength at elevated temperatures, high modulus, and broad chemical resistance. Polyetherimide stock shapes are inherently flame resistant with low smoke emission. Polyetherimide stock shapes display property retention and resistance to environmental stress cracking when exposed to a wide variety of chemicals. Glass filled grades appear tan or greenish in color. Polyetherimide rod, slab, and tubular bar are air annealed for stress relief.

Applications

Burn-in test sockets • Connectors • Automotive components • Valves, electrical fittings

Advantages of Polyetherimide (Glass Filled)

Inherent flame resistance • Extremely low NBS smoke evolution • Superior limiting oxygen index • Exceptional tensile and flexural strength • Broad chemical resistance • UV stable • FDA compliant

Manufacturing Capabilities

Rod: 1/4” to 8” diameter • Sheet: .035” to 1/4” thick • Slab: 3/8” to 4” thick

Color/Grades

Tan/Green • (custom colors available)
