Introduction to EPE pearl cotton EPE (expand ape poly ethylene), also known as pearl cotton, is foamed with butane and added with two auxiliary materials, industrial or medical ultra-fine talc and food grade anti shrinkage agent monoglyceride. The whole production process is physical change, so EPE is non-toxic. All auxiliary materials form independent bubbles and fine bubble structure in polyethylene, which makes EPE have high elasticity, toughness and non brittleness. It is an advanced protective interior material in the world. EPE has soft surface, white and pleasing appearance. As it is a completely independent bubble, it has light weight, heat insulation, waterproof, moisture-proof, shockproof, sound insulation and corrosion resistance; Strong anti-aging ability, good processability, adding electrostatic agent pink EPE raw materials, but also has a significant anti-static function. Bonding with Po film, aluminum film, woven fabric and other materials can also increase its tear strength and UV protection function. Because EPE has good processing performance, as long as the process is reasonable, the production of packaging products is convenient for large-scale operation; Because of its light weight, the transportation cost of packaged products is greatly reduced; Because of its shockproof resilience, the product packaging has good impact resistance, especially the multiple impact cushioning effect remains almost unchanged. Therefore, EPE is widely used in product packaging, such as computers, electrical appliances, high-end furniture, leather goods, handbags and shoes. Especially for high-grade handicraft packaging, EPE is combined with other high-grade decorative cloth and flannelette, which has a noble and luxurious style without losing its good impact and vibration protection effect, Z is the trend of high-grade packaging development in the future. The environmental protection characteristics of EPE have been recognized in the world. No other chemical components are produced in the production process of EPE. The waste EPE can be recycled and reused. It has no pollution to the environment and meets the environmental protection standards. The current situation that EPS styrofoam destroys the ecological environment increasingly shows the advantages of EPE in environmental protection.
