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 ( Flat Printed Circuit) mounting applications.
The acrylic adhesive gives this product an excellent temperature resistance up to 260°C. The highly conformable 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
