PU Foam Tape

PU foam is made of polyurethane as the main component. After physical foaming, low-density formula and special surface treatment technology are used to achieve functional foam with good sealing and shockproof performance and scratch resistance. It has excellent sealing performance and can avoid gas release and atomization; it can resist compression deformation, that is, the elasticity is durable, which can ensure long-term shockproof protection for accessories; it does not contain harmful substances, does not leave residues, and will not pollute equipment. Not corrosive to metals.

Use PU foam as the base material to laminate acrylic glue on one or both sides.
1. Panel interlayer: prevent loosening, prevent impact noise, and prevent adhesion.
2. Around the LED: prevent light leakage, absorb impact, and improve airtightness.
3. PCB lower periphery: shock absorption, vibration absorption, gap filling, heat insulation effect.
4. Keyboard gasket: rebound, no pollution, good dimensional stability.
5. Around the battery: no pollution, absorb impact sound, and improve air tightness.
6. Foot pad: good friction, no pollution, good dimensional stability.
7. Disk drive tail pad: absorb shock, prevent impact noise, and improve air tightness.
8. Friction gasket: good friction, no pollution, good dimensional stability.
9. Disk cover cushion: absorb vibration, block motor noise, shockproof, and improve air tightness.
10. Around the speaker: prevent noise and fill the gap.

PU Foam Tape is a professional-grade structural tape based on high-density polyurethane foam and coated with strong pressure-sensitive adhesive on the surface. Not only does this tape have excellent peel, shear and tensile strength, it also has excellent cushioning and shock-proof properties due to its unique foam structure. In addition, PU Foam Tape also has good weather resistance and can maintain stable performance in various environments.

Application scenarios
1. Electronic product manufacturing and assembly: In the manufacturing process of electronic devices such as smartphones, tablets, TVs, computers, etc., PU Foam Tape is used to fix internal parts, seal interfaces, as well as buffer and shockproof. Its excellent insulation and adhesion ensure the stability and safety of the equipment.
2. Automobile industry: In automobile manufacturing and maintenance, PU Foam Tape is widely used in sealing car body gaps, fixing interior parts, and pasting sound insulation materials, etc. Its excellent waterproof and shockproof properties help improve your car's comfort and durability.
3. Home decoration and construction: In home decoration, PU Foam Tape can be used to paste wallpaper, floors, ceramic tiles, etc., providing a stable bonding effect. In the construction field, it can also be used to seal windows and door gaps to improve thermal insulation performance.
4. Advertising and display: In advertising production and display, PU Foam Tape is often used for the production of models and sand tables, the repair of exhibition boards, and the fixing and pasting of various displays.
5. Daily maintenance and packaging: For repairing holes and gaps in daily life, as well as repairing wall tiles, floor tiles, and floors, PU Foam Tape can provide convenient and fast solutions. In addition, it can also be used for packaging and transportation, such as wrapping valuable and fragile goods to provide shock and pressure resistance.

Size and color
PU Foam Tape comes in a variety of sizes and specifications. Its length options include 10 meters, 20 meters, 50 meters, etc., widths include 1mm, 2mm, 3mm, 5mm, 10mm, 15mm, 20mm, etc., and thicknesses include 0.5mm, 1mm, 1.5mm, 2mm, 3mm and other different options. The specific choice depends on the actual use needs and application situations. For example, tapes for household use are generally shorter and thinner, while tapes for industrial production are generally longer and thicker.

In terms of color, PU Foam Tape is usually mainly black and gray. These two colors are simple and practical and suitable for most application scenarios. However, to meet different individual needs, we also offer other color options,
