Customized PPSU RTP 1499 PX Polyphenylsulfone

Customized RTP PPSU
Polyphenylsulfone, introduced by Union Carbide in 1965, was among the first thermoplastics developed for long term service beyond 300 degrees F (149 degrees C). Continuous use temperature, according to UL Method 746, is 302 degrees F (150 degrees C) for 40% glass reinforced polyphenylsulfone.

The addition of glass fibers to polysulfone results in nearly a twofold increase in tensile, flexural and compressive strengths and threefold increases in modulus values. Glass reinforcement lowers mold shrinkage.

The inherent properties of this material make it ideal for electrical and electronic applications.
