Polyethersulfone , color

As of November 1, 1995, the price range of UDEL polysulfone resias ia large quantities was 9.10— 12.03/kg depending on grade and color. RADEL A polyethersulfone grades sold for 10.46— 13.26/kg and the prices of RADEL R polyphenylsulfone resias were ia the range 15.75— 25.95/kg. MINDEL resias based oa polysulfoae had Hst prices betweea 6.72— 7.42/kg. 

Polysulfone It is a high performance amorphous plastic that is tough, highly heat resistant, strong and stiff. Products are transparent and slightly clouded amber in color. Material exhibits notch sensitivity and is attacked by ketones, esters, and aromatic hydrocarbons. Other similar types in this group include polyethersulfone, polyphenyl-sulfone, and polyarylsulfone. Use includes medical equipment, solar-heating applications and other performance applications where flame retardance, autoclavability and transparency are needed. 

The materials used for LFIA strips are nitrocellulose, nylon, polyethersulfone, polyethylene, fused silica, etc. A conjugate pad is where the analyte of interest forms a complex with the preimmobilized particles. Depending on the assay format, different types of particles may be immobilized in the conjugation pad ie, colloidal gold, colored or fluorescent particles, biomolecules, etc. In the detection pad, other specific biorecognition elements are immobilized and the interaction with the analyte is sensed using colorimetric, electrochemical, or another detection technique. The purpose of the absorbent pad is to wick the excess fluid so that higher sample volume can be used for better sensitivity.
