Self Adhesive Rubber Seal & Gasket, Silicone Rubber Seal Gasket with Double Side Tape, also called Adhesive Backed Rubber Seal & Gasket, Silicone Rubber Seal with tissue tape & adhesive tape, which is made from elastomeric silicone rubber molded gasket or components with adhesive backed double sided tapes & films by die-cutting tooling. One of common backing adhesive tape is 3M double sides tape & files which can peel adhesion to metal & steel, plastic, glass, wood, circuit board, elastomer silicon rubebr materials etc.
Following is mainly talking about different elastomer rubber gasket & sheets materials with single & double side adhesive tape or coating.
Rubber materials for backed adhesive: silicone, NBR & buna n, neoprene, EPDM, FKM, conductive silicone rubber.
1. Different rubber materials need to coated by different glue or with different backed adhesive tape
2. Not every rubber materials suit to self adhesive backed or & coated
Self Adhesive Silicone Rubber Seal Usage for electronic products
Improve electronics waterproof or anti-dust effects.
Electronic device with adhesive backed silicone rubber sealing gasket, which water & dust proof can to up IP55, IP56, IP57, IP65, IP66, IP67 grade etc.
Reduce or eliminates the EMI & RFI noise.
Electronic Products circuit board or plastic shells with Self Adhesive Conductive Silicone Rubber Gaskets, which can eliminates & reduces electro-magnetic interference or radio frequency interference.
Protect Plastic Shell or Housing Cover
Plastic electronic cover is easy to scratch or break if without backed adhesive sleeves & covers. Generally, silicone self adhesive cover, skins & sleeves, also need matte smooth coated for good touch feel and anti-dust, which upgrade products.
Self Adhesive Silicone Pads & Cushions also can used as products tags & lables.
Self Adhesive Backed Silicone Keypads & Keyboard, as a reliable switches componenst, which have good anti-dust and water proof effetcs.
Xiamen Better Silicone Co.,Ltd, which not only can make silicone rubber compression mold, plastic injection mold and LSR injection molding, but also can produce different kinds silicone rubber & plastic components or sealing gasket with adhesive backing:
Nitrile & Buna n adhesive backed gasket & seal
EPDM self adhesive sealing gasket
Neoprene & CR seal with self adhesive double sides tape
Adhesive Backed Silicone Rubber Keypads & Membrane Keyboard
Backing Adhesive Silicone keypads with metal domes
Adhesive Silicone Rubber Sleeves, covers & skins.
Backed Adhesive Silicone Rubber Seal & Gasket Manufacturing Process
1. Make silicone rubber compression mold
2. After finishing mold-making, producing silicone rubber samples for test. If dimensions are ok, sending the whole piece of silicone products to factory for dealing with silicone glue & tapes.
If big silicone rubber products, burring firstly, and then deal with silicone glue.
If small silicone rubber parts, generally dealing with silicone glue firstly, and then choose fixture tooling ( die-cutting) to burring. Or removing the big barbs, and then deal with the silicone glue, finally fixture tooling (die-cutting) to de-burring.
Knowledge of Self Adhesive Backed Tape Process
Paste double sided silicone 3m tape with the anti-adhesive sides of anti-adhesive paper;
b. Cutting the inner round holes by cutting die;
Silicone products are coated with silica gel treatment agent; (Notes: silica gel treatment agent should be even/ well-distributed; and should not coat on the surface of silicone products)
Accurate placed stick double sides silicone 3m tape, the surface of 3m tepe should be even.
(Notes: should not be a little off; and should not have bubble.)
Next Die Cutting for dis-burring & remove silicone rubber flashing
After finishing die cutting, check if have less materials or not clear cutting.
Test the finished products by 3D projects and amplification instrument
Before packaging, check the silicone glue one by one.
