Waterproof/Shock-Absorbing Foam Tape 5200 Series
A heat-resistant foam tape that delivers both waterproofing and shock absorption
A functional foam tape made from a PE or PP resin foam substrate combined with a high-adhesion adhesive. It provides excellent waterproofing, dustproofing, and impact absorption, while also offering outstanding conformability to uneven surfaces. Ideal for cushioning and bonding applications in precision devices such as smartphones and in-vehicle displays, it maintains reliable adhesion even under high temperatures and complex shapes.
- Electronics
Structure & Features
- Foam tape has strong adhesive strength and durability to absorb high impacts.
- Bond well onto uneven surface and excellent water and dust-proof capability.
- Excellent repulsion resistance and strong adhesion to bond to a curve surface of objects
- Available in grades that do not lose performance in 105°C conditions
Features
1High drop impact resistance
CheckDrop impact test
Evaluation method
- Cut a 3-inch squuare out of the sample tapes with a width of 2mm and 1mm respectively, and stick each of them to a PC board with its center cut.
- After that, apply a pressure of 5 kg to it for 10 seconds.
- Leave the board at the normal temperature for one day, and drop a weight on its center to measure the height from the point where the weight was dropped to the point where the PC board peeled and fell off.
Results
Exerts excellent impact absorption even when narrow.
2Strong adhesion properties
CheckAdhesion test (Push test)
Evaluation method
- Stick a sample tape on the PC board.
- Put an adherend on the tape with a weight of 5 kg for 10 seconds. Do the same thing with other adherends.
- Leave it at the normal temperature for one day, and press it through the hole as the picture shows to measure how much weight is needed until the adherend departs from the PC
Results
Strong adhesion that keeps it from peeling easily.
3Strong flexibility
Evaluation method
- Stack pieces of test tape 5 mm thick and apply pressure to the surface.
- Measure the amount of warping with the pressure applied and measure the flexiblity.
Results
Has excellent flexibility and the degree of flexibility can be chosen for the application.
4Strong heat resistance
CheckHeat resistance retention test
- Stick two adherends together and apply a weight on one side in the shear direction.
- Put in various temperature conditions for a long period and check if the weight causes it to fall.
