Kapton film is a brand name for Polyimide which is owned by Dupont. It is a non-thermoplastic polyimide film. It has a dark yellow colour and has an extremely high working temperature. The temperature range it can work within is -260C to +400c. This makes the film extremely versatile. Kapton does not have a melting point and has a low coefficient of linear expansion value. This would typically be 20 parts per mm / C. This is based on test valued of -14 to +38C. The film is not heat seal able but can be bonded to other surfaces which have a specially prepared surface.

Where this comes from

The part other shops don't tell you. Three separate questions, kept separate on purpose, each with its source.

UK company
Registered at Companies House as TECHBELT LTD, number 04433656. Checked 2026-08-29.
Means the business is a British legal entity, not a British-sounding name owned elsewhere. It says nothing about where anything is made.
UK operations
Not yet checked.
Means people employed here, or premises they actually work from. We keep this separate from the company badge because a registered office can be an accountant's spare room, and a company can be registered in Britain while everything it does happens somewhere else. Where we have not looked, we say so rather than assuming.
British-owned
Not established. Many companies file a statement rather than naming a controlling shareholder.
Read from the register of people with significant control, following the chain of holding companies. It does not gate anything: a firm can be made here and owned elsewhere, and that is worth telling you rather than hiding.
Where it is made
The maker doesn't say, so neither do we.
This is about the individual product, not the company. A British firm can sell things made abroad, which is normal and not a criticism. We would rather tell you which is which than average them into a score.
