EPO is a kind of "copolymer", which is produced by special polymerization process. It is composed of 30% polyethylene and 70% polystyrene. The PE component is mainly distributed in the outer layer of the particle, which promotes the combination of the plastic and the combination. The PS component is mainly distributed in the interior of the particles, which has a good supporting effect on the bubble structure.
1, EPO has very high tear resistance, scratch resistance and puncture, but resistance to fragmentation, compared with EPS, EPO need more than 2 times the strength to tear, 2 times larger than the power to expose, more than 4 times the torque to break.



The EPO density, which is used in the version of the KingTech EPO jet, is 20 times of the foaming rate, and the average EDF foaming rate is 40 times.The lower the ratio, the higher the hardness and toughness.
