Product Description
An amorphous thermoplastic polyetherimide, stock shapes from ULTEM® resin possess a combination of useful characteristics, including high strength at elevated temperatures, high modulus, and broad chemical resistance. Tempalux stock shapes are inherently flame resistant with low smoke emission. Tempalux stock shapes display property retention and resistance to environmental stress cracking when exposed to a wide variety of chemicals. The standard color of Tempalux stock shapes is light amber. Glass filled grades appear tan or greenish in color. Tempalux rod, slab, and tubular bar are air annealed for stress relief.
Manufacturing Capabilities:
  • Rod: 0.25 to 8 in diameter
  • Sheet: 0.035 to 0.25 in thick
  • Slab: 0.375 to 4 in thick
  • Film: 0.001 to 0.029 in thick
