tesa® 8857
50µm double sided translucent non-woven tape
Product description
tesa® 8857 is made from special tackified acrylic adhesive system which has excellent high temperature resistant property, ideal for demanding FPC mounting applications.
The acrylic adhesive gives this product an excellent temperature resistance up to 260°C. The highly comfortable ultra thin non-woven backing and highly temperature resistant release liner ensures it can be easily released without adhesive residue left or liner broken after reflow oven process.
Key features of tesa® 8857:
1 High temperature resistance with sufficient holding power and peel strength even after solder reflow process
1 High tensile strength, good repulsion resistance
1 Excellent die-cutting properties and very low oozing due to special backing
1 High conformability for uneven surfaces
1 High aging resistance
1 Conforming to RoHS
