Abstract: Improving surface tension of radiation crosslinked polyethylene (IXPE) foam by corona treatment be introduced .The main influence factors on surface tension such as ratio of materials, power and speed of corona treatment, product thickness, temperature, etc, have been studied.It has been observed that surface tension increase along with ratios; stronger power,slower speed, and higher temperature can improve the corona treatment results;the reduction of surface tension after corona treatment depends on storage condition of the materials.The material with surface tension reaching 38mN/m can maintain for a week,but it can be easily corona treated secondly.

Key words: radition crosslinked polythylene, foam material, corona effect, surface tension
