3M 9731 一面矽膠 一面壓克力膠 雙面膠帶

Product Description
3M Double Coated Tapes 9731 and 9731RW have a firm, silicone pressure sensitive adhesive coated on one side of a polyester film carrier and a high performance acrylic adhesive coated on the other side of the carrier. The silicone adhesive features strong holding power to various silicone surfaces, good temperature performance and good solvent resistance. This tape also features high adhesion of the acrylic adhesive to a variety of surfaces along with good high temperature performance and good solvent resistance.

Product Features
Silicone adhesive provides good bond to silicone rubber, strong holding power to various silicone surfaces, good temperature performance and good solvent resistance.
3M  Adhesive 350 provides very high adhesion to a wide variety of materials, excellent shear holding power, high temperature resistance and excellent UV resistance.
A thin polyester carrier provides dimensional stability and improved handling with ease of die cutting and lamination compared to adhesive transfer tapes.
