Variants
3M 5490 and 5491 are extruded Teflon film adhesive tapes with highly heat-resistant silicone adhesive, which differ mainly in thickness. They have excellent chemical resistance, a low coefficient of friction and good adhesive-repellent properties. As the Teflon film is extruded, the tapes have an extremely smooth surface and do not curl up when unwound.
- Excellent resistance to chemicals
- High temperature resistance
- Extruded PTFE adheres better to straight surfaces than peeled PTFEx
- Creates an extremely smooth surface
- Particularly suitable for gliding finishing of straight surfaces
- Extruded PTFE tape hardly rolls up when unwinding
- Short-term temperature resistance up to +260 °C
