Melting point: 148 °C (298 °F; 421 K) Boiling point: 397 °C (747 °F; 670 K) Solubility in water. Insoluble ... Udel Polysulfone Design Guide (Report). Alpharetta ...
Polyphenylsulfone has no melting point, reflecting its amorphous nature, [2] and offers tensile strength up to 55 MPa (8000 psi). Its commercial name is Radel. [ 3 ] In plumbing applications, polyphenylsulfone fittings have been found to sometimes form cracks prematurely or to experience failure when improperly installed using non-manufacturer ...
Above its glass transition temperature and below its melting point, ... Polyether sulfone (PES) or polysulfone is a class of specially engineered thermoplastics [6] ...
The compound (C 5 H 5) 2 TiS 5 is an example of a polysulfide complex. Polysulfides are a class of chemical compounds derived from anionic chains of sulfur atoms. [1] There are two main classes of polysulfides: inorganic and organic.
Melting point: −31 °C (−24 °F; 242 K) Boiling point: ... gamma-valerolactone showed the potential to fabricate polysulfone membranes as a co-solvent. [15]
Unlike hollow fiber membranes made from polysulfone, the aging process of the fiber is relatively quick so that air separation performance remains stable throughout the life of the membrane. PPO makes the air separation performance suitable for low temperature (35–70 °F, 2–21 °C) applications where polysulfone membranes require heated air ...
The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
