Note: The 1.0 mm thickness and listed dimensions are based on publicly available 320C product/application records rather than a current official 3M TDS. Exact adhesive chemistry, density, peel adhesion, shear strength and temperature performance should be confirmed against the specific 320C product configuration before being used as contractual specifications.
Applications
- General mounting
- Sign and display mounting
- Advertising material mounting
- Nameplate attachment
- Decorative component mounting
- Picture frame mounting
- Lightweight component assembly
- Office and stationery applications
- Household mounting
- Automotive accessory mounting
- Electronics component fixing
- General industrial assembly
320C is also documented in converted-component applications, where a 24 × 14 mm × 1.0 mm piece was used as a double-sided foam tape component.
Compatible Materials
Depending on the actual surface condition and application, 320C can be considered for bonding:
- Metal
- Aluminum
- Painted metal
- Plastic
- ABS
- Acrylic
- Glass
- Wood
- Paper
- Cardboard
- Decorative panels
- General rigid substrates
For critical applications, adhesion should be tested on the actual substrate because surface energy, roughness, coatings, contamination and load can significantly affect performance.
Industries
- Electronics
- Automotive
- Advertising & Signage
- Appliances
- Office & Stationery
- Furniture
- Packaging
- General Manufacturing
- Retail Display
- Household Products
- Industrial Assembly
Why Choose
3M™ 320C Double-Sided Foam Tape is a practical solution for applications requiring a white, approximately 1.0 mm thick, double-sided foam adhesive tape for mounting and general bonding.
Its foam construction provides more conformability than a conventional thin double-sided film tape, while the double-sided adhesive structure allows components to be mounted without conventional mechanical fasteners.
For B2B customers, Yousan can provide converting options including:
- Custom widths
- Narrow-width slitting
- Custom roll lengths
- Jumbo-roll converting
- Die-cut adhesive parts
- Kiss-cut components
- Custom shapes
- Laminated constructions
- OEM packaging
Installation Guide
1. Clean the surface
Remove dust, oil, grease and other contaminants from both bonding surfaces.
2. Dry the substrate
Make sure the surfaces are completely dry before application.
3. Cut or slit the tape
Select a suitable width and length according to the bonding area.
4. Apply the tape
Apply 320C evenly to the first substrate and avoid wrinkles or trapped air.
5. Apply pressure
Press the tape firmly across the entire bonding area.
6. Remove the liner
Carefully remove the release liner without contaminating the exposed adhesive.
7. Bond the second substrate
Position the second component accurately and press firmly into place.
8. Allow sufficient bonding time
Avoid excessive loading immediately after application and allow the adhesive bond to develop.
Storage
Store 3M 320C in its original packaging in a clean, dry indoor environment.
- Keep away from direct sunlight.
- Protect from excessive heat and moisture.
- Avoid dust and contamination.
- Keep rolls flat and properly packaged.
- Avoid excessive pressure or deformation.
- Confirm the manufacturer’s storage and shelf-life requirements for the specific product batch before long-term storage.
FAQ
Q1: What is 3M 320C?
3M 320C is a double-sided foam adhesive tape used for mounting, fixing and general bonding applications.
Q2: Is 3M 320C double-sided?
Yes. 320C is identified as a double-sided foam tape.
Q3: What is the thickness of 3M 320C?
Publicly documented 320C examples identify a 1.0 mm thickness.
Q4: What widths are available for 3M 320C?
Publicly listed configurations include 12 mm, 18 mm, 24 mm and 36 mm widths, generally with 5.5 m roll lengths in consumer/standard configurations.
Q5: What color is 3M 320C?
Public product listings identify 320C as white.
Q6: Can 3M 320C be used for mounting?
Yes. Mounting and fixing are common application categories for this double-sided foam tape.
Q7: Can 3M 320C be die-cut?
The foam-tape construction can be converted into custom adhesive pieces. For production applications, die-cutting should be evaluated based on the specific tape configuration and required tolerance.
Q8: Is 3M 320C a VHB tape?
No. 320C should not be presented as 3M VHB™ tape. It is a separate double-sided foam tape product.
Q9: Is 3M 320C suitable for high-temperature applications?
Do not market 320C as a high-temperature tape unless the specific product documentation confirms the required temperature performance. The publicly available sources reviewed here do not provide sufficient official temperature data to support a specific temperature claim.
Q10: Can Yousan provide custom 320C converting?
Yes. Depending on the supplied material configuration, Yousan can provide slitting, custom-width rolls, die-cut adhesive parts and other converting services.
