PET sheet
(polyethylene terephthalate) is a versatile thermoplastic known for its excellent dimensional stability, strong mechanical properties, and resistance to deformation under load. It withstands chemical exposure well, absorbs minimal moisture, and acts as an effective electrical insulator. Its durable, hard surface is ideal for wear applications and can be precisely machined and polished.
Henry Gallacher utilises advanced in-house 5-axis CNC machining to shape PET sheet into a variety of precision components, including bearings, gear wheels, control discs, and electrical insulators. Additionally, PET is suitable for fabricating tank lids, pump parts, friction strips, and serves effectively as a gas barrier.

PET sheet is stocked in various sizes and thicknesses. We also supply
PET (Ertalyte®) sheet
as a branded alternative when required.
Applications
PET sheet is commonly fabricated into components such as bearings, pump parts, frame elements, tank lids, insulators, friction strips, and control discs. It is widely used across mechanical, marine, electrical, food, and pharmaceutical engineering sectors.
