3M9448 is a non-woven fabric base double-sided tape in 3M double-sided tape. It is made of non-woven fabric coated with acrylic adhesive on both sides. It has good initial adhesion and holding adhesion, easy die-cutting processing, and good stability. , Good adhesion to plastics, rubber, rough surfaces; good holding power at high temperatures, long-term temperature resistance of 80 ℃: short-term temperature resistance of up to 120 ℃; according to the color of the tape, it is divided into white glue and black glue.

The bonding strength increases with the increase of the contact area between the adhesive and the surface to be adhered. Applying a stable pressure will help the adhesive and the surface to be adhered, thereby increasing the bonding strength.

To achieve the best bonding effect, the bonding surface must be clean and dry. The best temperature range for tape application is 21-38℃. It is recommended that if the initial bonding temperature is lower than 10℃, it is not suitable for bonding, so When the adhesive is too hard, it cannot be firmly bonded to the object; however, if it has been bonded, the holding power at low temperature is also satisfactory.

Applications:

Double-sided tape meets the requirements of ROHS regulations in terms of environmental protection, and is widely used in the processing industry, including the bonding of rubber strips and plastics in the rubber and plastic industry. It is suitable for the bonding of refrigerator evaporators and control panels, nameplate bonding, household appliances, automobiles, etc. Mobile phones, sponges, paper products, toys, etc.; vinyl is especially suitable for bonding electrical appliances lenses, and has the effect of preventing light transmission.

characteristic:

1.3M hot melt adhesive film combines the advantages of adhesive film and hot melt technology, which is suitable for fibers, polyolefins, liquid crystal polymers, and temperature-sensitive materials

It has excellent performance on many substrates such as metal and metal, providing a variety of options from temporary bonding to permanent bonding.

2. Precise and uniform film thickness, providing consistent glue layer

3. It can be punched into precise shapes and sizes, suitable for purely manual or automated applications

4. It sticks after heating for a few seconds, no fixtures, fast assembly

5. Provide a dielectric insulation layer

6. Provide a lap shear strength of up to 2500psi on aluminum materials
