How to distinguish PE foam and EVA foam?

    Foams are also called sponges. They are divided into many types, such as EVA foam, PE foam, PU foam, etc. It is necessary to determine which foam or sponge is suitable for use according to its specific use. EVA is a new type of foaming material. EVA foaming material is composed of the main material EVA, fillers, foaming agents, bridging agents, foaming accelerators, lubricants, auxiliary materials: leftovers, antistatic agents, flame retardants , Quick-curing agent, coloring agent, the raw material is beaten into soft glue through a glue machine, and the soft glue is pressed into a sheet through a roller machine, and the sheet material is put into a large flat foam mold, and passes through 160 to 170 High temperature, foam molding, this process is made of plates, and the desired size and thickness are drawn through the cutting machine.

    The essential difference between EVA foam, PE foam and EVA foam is their materials. PE foam double-sided tape is made of polymer foam material as the base material, double-sided coated with high-performance pressure-sensitive adhesive (acrylic acid adhesive or rubber-based adhesive), compounded with mono-silicon or double-silicon release materials.

    PE foam double-sided tape refers to a double-sided tape made of PE foamed substrate coated with acrylic glue on both sides. The colors are mainly white, black and gray. The commonly used thicknesses are 0.3mm, 0.5mm, 0.8mm, 1.0mm, 1.5mm, 2.0mm and 3.0mm. The foam foaming multiples are 5, 8, 10, and 15 , 20 times and 30 times, the release is mainly release paper (white, yellow) and release film (red, green, blue, orange), use: suitable for photo frame decoration strips, furniture decoration strips, car decoration strips, Paste and fixation of corrugated board, wheel arc, baffle, brake light, car logo, motorcycle logo, electrical nameplate, wool top, etc. Features: strong adhesion, good retention, UV resistance, temperature resistance, water resistance , Solubility and plasticity resistance. Applicable temperature: -20℃~120℃.

    Distinguish between PE foam and EVA foam: surface pores can be distinguished, PE foam has no small holes, the main raw material of PE foam is PE plastic particles, and the main raw material of EVA foam is EVA plastic particles.
