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.
