High Temperature Resistant Polyurethane Base Material -EF0F-PU
EFOF - PU high temperature resistant polyurethane conductive product is made by wrapping the highly resilient foam using conductive fabric, with conductive adhesive on the back. It has wide and favorable EMI shielding property, which can provide an excellent solution for EMI. It can also provide non-conductive or conductive pressure-sensitive adhesive belt and can attach a release liner layer to the belt. They can be made into cross-sectional shapes like rectangle, D-shape, C-shape, P-shape, T-shape, knife shape and bell shape, and can be further customized for different applications through die cutting, perforating, grooving etc. It contains no halogen and conforms to the requirement of RoHS / REACH.
