Allied Colloids's Issue - Solution - FEP/GRP Vessels Background Allied Colloids are producers of flocculating gel which absorbs moisture in nappies etc. During the manufacturing process, a chemical reaction is induced in a cocktail of chemicals and they are transformed into a jelly-like consistency inside large tapered cauldrons. The cauldrons are then inverted to allow the gel to drop out. Problem The problem stemmed from the fact that the consistency of the gel was such that it was difficult to drop out. As the gel moved down the cauldron a vacuum was formed above it which made it even more difficult. What was needed was a non-stick surface which was also chemically resistant. The obvious choice is a fluoropolymer with their unsurpassed non-stick capability and blanket chemical resistanc
