WF Film
The most commonly used Gel-Film® product is the WF film which is Gel bonded to a metalized polyester substrate material which gives a light gray appearance. WF is available with optional Pressure Sensitive Adhesive (PSA) backings which enables mounting of the film to any flat working surface (i.e. fixture, table).
WF film is available in standard square, rectangular, and round sheet sizes or can be custom cut to any shape and size per the customer’s specific requirements.
Applications with the PSA backing
- Disk Drive Row Bar Lapping
- Process Handling Fixtures
- Flex circuit laser cutting
- Sealing Gaskets
- Kitting of small components
- High Temperature Processes (up to 150°C)
Applications without the PSA backing
- Surface Protection
- Polishing Optics
- Scribe and Break cover sheet
- Flat panel display cover
- Support for handling fragile wafers
- Wafer Backgrinding
- High Temperature Processes (up to 150°C)
Stock Availability and Minimum Order Quantities (MOQ)
- WF-40x40-0060-X4 (MOQ 1 sealed pack of 50 units)
PF Film
The PF is similar to the WF product except the Gel material is not bonded to its clear polyester substrate. This allows the Gel Film® material to be easily removed from the polyester backing material, otherwise known as "Free-Gel". The PF film is optically clear. The more commonly used version of “Free-Gel" is the purified Gel version referred to as DGL Film.
PF film is available in standard square, rectangular, and round sheet sizes or can be custom cut to any shape and size per the customer’s specific requirements.
Applications
- Process Handling Fixtures requiring optically clear film
- Finger Print Recognition
- High Temperature Processes (up to 220°C)
DGL Film
DGL film is a Process B version of the PF "Free-Gel" film. The optically clear purified Free-Gel is laminated onto a flexible polyethylene backing with an easy to remove polycarbonate material used as the coversheet. For applications where a double-sided Gel material is required, DGL is typically the Gel-Film® product of choice. The Free-Gel can be exposed up to 220°C for long duration. DGL film is available in standard sizes or can be sold in any custom shape and sizes per your specific requirements.
Applications
- Vacuum Coating Processes
- Scribe & Break Coversheet
- High Temperature in-process handling
- Temporary Wafer Bonding
- Disk Drive Lapping
