Use and Classification of Foam Tape!
May 30,2022
There are many kinds of materials used in die-cutting. How match and select different materials is also a key to testing the ability of a die-cutting master. Foam glue is also quite common in die-cutting.
When selecting foam tape for die-cutting operation, you can think from the following aspects and choose the foam tape suitable for your products.
Foam tape is made of EVA or PE foam as the base material, coated with solvent type (or hot-melt) pressure-sensitive adhesive on one or both sides, and then coated with release paper. It has the function of sealing and shock absorption. It has excellent sealing, compression deformation resistance, flame retardancy, wettability, etc. The products are widely used in electronic and electrical products, mechanical parts, various small household appliances, mobile phone accessories, industrial instruments, computers and peripheral equipment, automobile accessories, audio-visual equipment, toys, cosmetics, etc.
Main characteristics of foam tape
- It has excellent sealing performance and avoids gas release and atomization.
- Excellent compression deformation resistance, that is, the elasticity is durable, which can ensure the long-term shock protection of accessories.
- It is flame retardant, does not contain harmful and toxic substances, does not remain, does not pollute equipment, and is not corrosive to metals.
- It can be used in a variety of temperature ranges. It can be used from minus degrees Celsius to degrees Celsius.
- The surface has excellent wettability, easy to bond, easy to make, and easy to cut.
- Long-lasting adhesion, large peeling, strong initial adhesion, and good weather resistance! Waterproof, solvent resistant, high temperature resistant, good adhesion on curved surfaces.
Classification of foam tape
By glue system: hot-melt type foam tape; Oil gel foam tape.
According to the size of foam: perforated foam tape; Closed-cell foam tape; Semi closed-cell foam tape.
According to characteristics: high-temperature resistant foam tape; Flame retardant foam tape; Conductive foam tape; High-density foam tape; Low-density foam tape.
By base material: pe/ipe foam tape; EVC foam tape; PVC foam tape; PU foam tape; EPDM foam tape; CR foam tape; SBP foam tape; NBR foam tape.
Application and storage method of foam tape
Application: the products are widely used in the insulation, pasting, sealing, anti-skid, cushioning, and shockproof packaging of electronic and electrical products, mechanical parts, various small household appliances, mobile phone accessories, industrial instruments, computers and peripheral equipment, automobile accessories, audio-visual equipment, toys, cosmetics, craft gifts, medical instruments, electric tools, office stationery, shelf display, home decoration, acrylic glass, ceramic products, and transportation.
Storage method: the suitable temperature for foam tape: is 21 ℃ --38 ℃, and suitable pressure of at least 5kg/ ㎡. It is forbidden to contact acid-base oil organic solvents. Keep it clean and dry. The room temperature is between -15 ℃ and 40 ℃.
When the foam is used as the base material, it is very suitable for irregular surfaces because of its very soft texture. It can also smooth moving and stretch materials. The ability to absorb load is also very strong. Foam is widely used as a base material in PVC windows, refrigerators, furniture, and decorative profiles, mainly because it can provide ideal support for very tight bonding.
The printing industry is also one of its special fields. The hardness of the foam in the tape determines the contact pressure of the printing plate, which helps the printer control the grid points on the paper. The foam tape can also absorb the vibration generated by the high-speed operation of the printing machine to avoid the occurrence of stripes during the printing process.
With the emergence of new foaming materials, there will be more foam base tapes. Xingsheng R & D team will not forget the original intention, forge ahead, develop and produce higher quality adhesive tape products.
