Foam gasket tape is a multifunctional tape product. It uses foam as the core material, and is coated with adhesive on one or both sides of the foam, and covered with release paper or release film for easy storage and use. Foam is used as the base material, and common ones include polyurethane foam, polyethylene foam (PE foam), ethylene-vinyl acetate copolymer foam (EVA foam), etc. These foam materials have unique physical properties, such as softness, elasticity and certain buffering capacity. There are also many types of adhesives, such as acrylic adhesives, which are used to firmly combine the foam with the object to be pasted.
2. Product characteristics
- Buffering performance: The foam component in the foam gasket tape gives it excellent buffering capacity. When impacted by external force, the foam can absorb energy through its own elastic deformation, thereby protecting the object to be pasted from damage. For example, during the transportation of electronic products, foam gasket tape can prevent internal components from being damaged due to collision.
- Sealing performance: Due to the softness and compressibility of foam, foam gasket tape can fill irregular surface gaps and achieve good sealing effect. In the construction industry, it can be used to seal the gaps between doors and windows to prevent the penetration of air and moisture.
- Sound absorption and noise reduction: The porous structure of foam helps to absorb sound waves and reduce noise transmission. Using foam gasket tape inside the car can reduce noise during driving and improve the comfort inside the car.
- Temperature resistance: Different types of foam gasket tapes have different temperature resistance ranges. Some high-quality products can maintain stable performance over a wide temperature range, whether near the heat dissipation area of electronic equipment in a high temperature environment or in low-temperature outdoor facilities.
- Viscosity characteristics:
The adhesive has appropriate initial adhesion and lasting adhesion. The initial adhesion allows the tape to quickly adhere to the surface of the object at the beginning of pasting, and the lasting adhesion ensures a long-term pasting effect, ensuring that it will not fall off easily during use.
3. Product application areas
- Electronic and electrical fields: In electronic devices such as mobile phones and tablets, foam gasket tape is used to fix components such as batteries, cameras, speakers, etc. to prevent them from loosening during the use of the equipment. At the same time, it can also play a role in shock absorption, heat dissipation and sealing, protecting electronic components from the influence of the external environment.
- Automobile industry: Foam gasket tape is widely used in the installation of automotive interior parts, such as the pasting of dashboards, door interior panels, etc. It is also used for the fixing of automotive exterior parts, such as body logos and rearview mirrors, and in the engine compartment of the car, it can buffer, seal and soundproof some pipelines.
- Architectural decoration field: It is used for sealing and fixing building doors and windows to improve the heat insulation and sound insulation effect of buildings. In interior decoration, it can also be used to fix decorative lines, wall stickers, etc. Its good viscosity and buffering properties enable it to adapt to different wall materials.
- Machinery manufacturing field: Buffer and fix some precision mechanical parts to prevent wear and collision between parts. For example, in machine tool equipment, it can be used to fix control panels or as a buffer material between some moving parts.
4. How to choose foam gasket tape
Choose the type of foam according to the application scenario
If it is used in a high temperature environment, such as near the engine compartment of a car, you should choose a gasket tape made of EVA foam with good temperature resistance or special high temperature resistant foam. For scenarios that require high cushioning performance, such as transportation protection of electronic products, polyurethane foam gasket tape may be a better choice.
Consider adhesive properties
When the object to be pasted is a low surface energy material (such as some plastics), you need to choose a foam gasket tape with a high viscosity acrylic adhesive. If the product may be exposed to a humid environment, make sure that the adhesive has good water resistance.
Determine thickness and size requirements
Choose the thickness of the foam gasket tape according to the actual pasting gap or the space that needs to be filled. In some electronic devices with space restrictions, it is necessary to accurately select the right thickness of tape. At the same time, according to the shape and size of the object to be pasted, choose the right size of tape, or consider whether custom cutting is required.
5. How to use foam gasket tape
- Surface treatment: Before pasting the foam gasket tape, it is necessary to ensure that the surface to be pasted is clean, dry, and free of impurities such as oil and dust. For some materials with low surface energy, surface treatment methods such as wiping with special cleaning agents or polishing can be used to improve the pasting effect.
- Paste operation: Carefully peel off the release paper or release film of the foam gasket tape, accurately stick the foam gasket tape to the predetermined position, and then press the tape evenly from one end to the other end with appropriate pressure to ensure that the tape is in full contact with the pasted surface and eliminate air bubbles.
- Inspection and maintenance: After pasting, check whether the tape is firmly pasted and whether there are bubbles or warping. During use, if the foam tape is found to be less sticky or loose, it should be checked and re-pasted in time.
Foam gasket tape uses foam as the core material, with adhesive applied on one or both sides and covered with release paper/film. Its characteristics include cushioning, sealing, sound absorption and noise reduction, temperature resistance and viscosity. Application areas include electronics, automotive industry, architectural decoration and machinery manufacturing, etc. When selecting, you need to consider the foam type, adhesive properties, thickness and size; when using, you need to perform surface treatment, correctly paste and inspect and maintain.
