Back in the early 1990’s, Holscot was contracted by what was then Allied Colloids to manufacture cauldrons for the production of flocculating gel (Sodium Polyacrelate) used in hygiene absorbent pads such as nappies.  The end product is made in large tapered chemical vessels and, once a chemical reaction takes place, the consistency becomes that of a jelly so it is very difficult to extricate.  The customer needed a non-stick, chemically resistant liner to solve the problem (a coating would simply have not been durable enough).  They tried many potential solutions but the only one that worked was a glass backed FEP liner overwrapped with GRP and integrated into the existing Stainless Steel Vessels.

At the time, Holscot worked with Northern Plastics in Bradford to create 66 of these cauldrons for the Allied Colloids plants in Bradford and Grimsby, England.

More than 25 years later, some of these original cauldrons are finally reaching the end of their lives and the time has come to renovate them.  Once again, Holscot has stepped up to the plate and is working with Engenda in Elland to take the existing vessels, strip out the FEP/GRP element and completely replace them.  We are fortunate to have many long-standing experts within our business who recall the original chemical vessels and now are responsible for training the newer members of the workforce to carry out the renovations.

Once complete, it is hoped that they will be able to get another 25 years of production out of them, with little or no maintenance needed in the intervening period.
