Avon Technical Products in Melksham, UK developed a way to fit the PFA sleeve without using heat shrinkable sleeving. However, it still relied on perfect PFA extrusions. Holscot worked closely with Avon to perfect a PFA sleeve which had to comply to exacting tolerances. The PFA sleeves have to be etched on the ID using the sodium ammonia technique. This process can often have a splashy appearance but this would not be desirable on the finished roller so Holscot developed an in house process which ultimately provided an even shade of etch within the roller. Holscot now supplies a wide diversity of PFA and FEP sleeves of varying thicknesses to the same exacting tolerances to a number of rubber roller manufacturers servicing the photocopier and printing industries.
