3M™ Low Outgassing High Shear Polyester Tape 8439FL is a silver colored polyester film tape for the demanding requirements of hard disk drive and related electronics manufacturing.
The metalized polyester backing offers low static and diffusivity and is complimented with a very low outgassing acrylic adhesive. This product offers a high level of permanence, yet is cleanly removable from most substrates even after extended heat treatments. 3M™ Non-Silicone Polyester Liner 5932 completes the construction. 3M™ Clean Seal Tapes are low outgassing tapes, which help reduce the risk of chemical contamination leading to head corrosion and media fogging which may cause hard disk drive failure.
