How to distinguish between PE foam and EVA foam?
Some people also called foam sponge is divided into many kinds of such as EVA foam, PE foam PU sponge, etc. according to their specific purposes to determine which foam or sponge suitable for use. EVA is a new type of foam material, EVA foam material is composed of EVA, filler, foaming agent, bridging agent, foaming accelerator, lubricant, excipients: scrap, antistatic agent, flame retardant , Quick-start agent, coloring agent composition, after playing the plastic machine to the raw material into a soft plastic, through the roller into a sheet of soft plastic, the sheet material into a large flat foam mold inside, after 160 to 170 Degree of high temperature, foam molding, this process is made out of the plate, after the opening machine out of the desired size and thickness.
EVA foam PE foam and EVA foam the essential difference is that their material. PE foam double-sided tape to polymer foam material as a substrate, double-sided coating of high-performance pressure-sensitive adhesive (acrylic adhesive or rubber-type adhesive), composite single-silicon or double-silicon from the material from.
PE foam double-sided adhesive refers to the PE foam on both sides of the substrate coated with acrylic glue made of double-sided adhesive. Color is mainly white, black and gray, commonly used thickness of 0.3mm, 0.5mm, 0.8mm, 1.0mm, 1.5mm, 2.0mm and 3.0mm, foam foam multiples 5 times, 8 times, 10 times, 15 times , 20 times and 30 times, the release is mainly for the release paper (white, yellow) and release film (red, green, blue, orange) Uses: Suitable for photo frame decoration, furniture decoration, car decoration, Wave plate, arc, block flow, plate brake lights, car labels, motorcycle signs, electrical nameplate, tops and other aspects of the paste fixed role, characteristics: strong adhesion, good holding power, UV, temperature resistance, water resistance , Soluble and plastic-resistant. Suitable temperature: -20 ℃ ~ 120 ℃.
Distinguish between PE foam and EVA foam: the surface pores can be separated, PE foam is no small hole, PE foam is the main raw material of PE plastic particles, and EVA foam is the main raw material of EVA plastic particles.
