In the case of polymeric membranes, IEC has had extremely encouraging results when applying modified polysulphone
and polyamide membranes to prevaporation.
The list of high-performance polymers analysed in the Frost & Sullivan study includes fluoropolymers, high-performance polyamides, liquid crystal polyesters, polyphenylene sulphides, polyketones, and polysulphones
Made from polysulphone
, these connections are available to fit 3/4in.
Tenders are invited for Hollow Fiber Low Flux Dialyzer - Polysulphone
Super-toughness has been observed in thermoplastics that include poly(butylene terephthalate) (PBT) [1, 4, 8, 9, 13-15], poly(ethylene terephthalate) (PET) [12, 16-22], nylon [5, 6, 10, 23], polysulphone
(PSU) , and polyolefins [2, 3], mostly thanks to the chemical modification of the impact modifier or the use of compatibilizers.
A layer of non woven polyester gives structural strength, whilst a layer of microporous polysulphone
offers high permeability as well as resistance against compaction under high pressure.
Produced by The Inline Process Co of Heron House, 109 Wembley Hill Road, Wembley, Middlesex, tel:020 8907 5300, these Glass-Less sight tubes are tailored to user requirements and produced in polysulphone
or cast acrylic that is suitable for all types of process equipment, for use in sterile environments and under hygienic conditions.
4), reported that polypropylene exhibited an excellent fatigue resistance during large strain cyclic deformation and that ductile polymers (polycarbonate, nylon, polyoxymethylene, polysulphone
, and ABS, etc.
Super-toughness has been mainly obtained not only with semicrystalline thermoplastic matrices such as polyolefins (14), (15), (27), (28), poly-amides (8), (21-23), and polyesters (1-4), (9-13), (16-20), (32), (33), but also with amorphous ones, such as polysulphones
(7), polycarbonate (24) or poly(vinyl chloride) (25).
Membranes based on other thermally stable polymers, such as polysulphones
, polyether ketones, and polyimides have been widely studied but have not, hitherto, been commercialised on a large scale (6-8).
