Die-cutting material| Tips on selecting foam adhesive tape

In the die-cutting process, a variety of materials are used, so the key to testing the ability of a die-cutting master is how to match and select different materials. Foam tape is also commonly used in die-cutting processing.

Foam tape is made of EVA or PE foam, with solvent-type (or hot-melt) pressure-sensitive adhesive applied on one or both sides, and then made into release paper. It has the function of sealing and shock absorption. It has excellent sealing performance, compressive deformation resistance, flame retardancy, wetting property, etc. The product is widely used in electronic and electrical products, mechanical parts, various small household appliances, mobile phone accessories, industrial instruments, computers and peripherals, automotive parts, audio-visual equipment, toys, cosmetics, etc.

What to know before using foam tape:

1. Before using foam tape, you should have a comprehensive understanding of it, including its use method, storage environment, service life, etc.

2. Proper temperature when using foam tape: 21 degrees to 38 degrees Celsius, with a proper pressure of at least 5 kg/cm².

When selecting foam tape in die-cutting operation, you can consider the following aspects and choose the foam tape suitable for your product. I hope the following summary by the editor can be helpful to you:

1. Thickness of foam tape: The accuracy of the thickness of foam tape will affect the quality and output of the die-cutting product.

2. From the perspective of material suppliers, there are many high imitation products on the market due to the variety of foam types, such as 3M VHB tape, Jisusui, etc. Brand awareness is also important.

3. Choosing from colors: For foam tape, white, black, gray, light gray, and usually gray are common, but different customers have different requirements. Customer demand is the most important.

4. Choosing from density: Different foam tapes should be selected for different die-cutting products.

5. Different elasticity: Different models of foam have different elasticity.

Main characteristics of foam tape:

1. Excellent sealing performance, which can prevent gas release and atomization.

2. Outstanding compressive deformation resistance, that is, the elasticity is durable, which can ensure long-term shock protection for accessories.

3. It has flame retardancy, does not contain harmful and toxic substances, does not leave residue, does not pollute equipment, and does not corrode metals.

4. It can be used in various temperature ranges. It can be used in a temperature range of -40 degrees Celsius to 90 degrees Celsius.

5. The surface has excellent wetting property, easy to bond, easy to manufacture, and easy to punch.

6. It has long-term viscosity, high peeling force, strong initial viscosity, waterproof, solvent-resistant, heat-resistant, and good fit on curved surfaces.

The selection techniques and related characteristics of foam tape as die-cutting materials are introduced today. Foam tape may seem simple, but the production process is actually very complicated, and each link has stricter requirements, especially the control of the die-cutting process. Only high-quality die-cutting machines can produce high-quality products and reduce waste and cost to some extent.
