Polysulfone food pans are used for the storage, heating, and serving of foods. The pans are made to Gastronorm standards and are available in the natural transparent amber colour of polysulfone. The wide working temperature range of -40°C to 190°C allow these pans to go from a deep freezer directly to a steam table or microwave oven.
The specific production methods involved are heavily dependent on the type of polymer used as well as its molecular weight. HFM production, commonly referred to as "spinning", can be divided into four general types: Melt Spinning, in which a thermoplastic polymer is melted and extruded through a spinneret into air and subsequently cooled.

PPSF is a moldable plastic often used in rapid prototyping and rapid manufacturing (direct digital manufacturing) applications.Polyphenylsulfone is heat and chemical-resistant suited for automotive, aerospace, and plumbing applications.
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 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.
The chemical and physical properties of synthetic membranes and separated particles as well as separation driving force define a particular membrane separation process. The most commonly used driving forces of a membrane process in industry are pressure and concentration gradient. The respective membrane process is therefore known as filtration ...
Figure 1: Comparative Costs and Production Volumes For Processing of Plastics. The economics of plastics processing is determined by the type of process.Plastics can be processed with the following methods: machining, compression molding, transfer molding, injection molding, extrusion, rotational molding, blow molding, thermoforming, casting, forging, and foam molding.
This way, potentially expensive design and production steps of e.g. affinity resins can be avoided. Finally, by filling the whole volume of the particle pores with an extractant (complexing agent), a higher capacity for solutes can be achieved than with ordinary adsorption or ion exchange resins, where only the surface area is available.
