Product information

tesa® 8851

30µm double sided translucent non-woven tape

Product description

tesa® 8851 is an ultra thin double-sided non-woven tape, which has excellent temperature resistance property, ideal for micro-speaker dome mounting and FPC mounting applications.

tesa® 8851 is made from special tackified acrylic adhesive system and uses an ultra thin non-woven backing, which offers excellent temperature resistance up to 260°C and excellent converting performance. The temperature resistant glassine liner ensures it can be easily released after solder reflow process.
