Can EVA foam be replaced with EPE pearl cotton or sponge?

    EPE pearl cotton is an earthquake-resistant packaging material such as computer hardware. Foam sponge was used in the past, but now more pearl cotton is used. Its seismic effect is better and it is easy to fix.

    EVA foam is a kind of foam. Foam is a material that has been foamed by plastic particles to form foam. The foam is divided into PU foam, anti-static foam, conductive foam, EPE, anti-static EPE, PORON, CR, EVA, bridging PE, SBR, EPDM, etc. EVA is one of the foam products, and it is also called EVA sponge. EVA can be foamed according to individual requirements, and the hardness can also be adjusted according to requirements. Foam has a series of characteristics such as elasticity, light weight, fast pressure-sensitive fixation, convenient use, free bending, ultra-thin volume, and reliable performance.

    The main characteristics of EVA foam products are high precision, the uniformity of the entire roll of materials is highly accurate, and it can be cut with confidence after coating, without delamination, and has a high degree of compatibility with adhesives, and no non-sticky The main specifications are 41" (1040mm) and 42" (1070mm), which are suitable for hot melt adhesive and acrylic oil coating.

    Commonly used sponges are made of wood cellulose fibers or foamed plastic polymers. In addition, there are also natural sponges made of sponge animals. Most natural sponges are used for body cleaning or painting. In addition, there are three types of synthetic sponges made of other materials, namely low-density polyether (non-absorbent sponge), polyvinyl alcohol (high-absorbent material without obvious pores) and polyester.

    1. A relatively common midsole material, usually called a foam, has a certain cushioning effect, but this material is very slippery, so it is generally mixed with hard rubber. EVA is a common material and is mostly used Electronic appliances, plastics and other products.

    2. Daily necessities: foam shoe material, functional shed film, packaging film, hot melt adhesive, wire, cable and toys, etc.

    EVA self-adhesive method:

    1. Easy to use: No need to punch holes, just gently take out the single EVA formed on each large piece of EVA, the release paper at the bottom will automatically separate from the foot pad, and then press to the desired product position.

    2. Strong adhesion: The pressure-sensitive adhesive technology (3Mpad) with long-lasting performance can fix the EVA in place and help prevent sliding and falling off. Domestic double-sided adhesives are mostly used: hot melt adhesive, oil glue, embroidery glue and water glue; imported double-sided adhesives: 3M, NITTO, TESA, SONY, Hi-Bon (Hitachi).
