UHMWPE (ultra-high molecular weight) powder activation For many applications, hydrophilic UHMW polyethylene powder is used as innovative option. It can be used as an additive in rubber, resulting in an increased tear propagation strength. Furthermore, hydrophilic PE powder can increase the bonding strength between metal and plastic. This hydrophilization is made possible by low-pressure plasma treatment. The treatment parameters strongly depend on the particle size of the powder. Plasma treatment can take between 5 minutes and several hours. Thermal damage to the powder is excluded since the process temperature remains low the whole treatment time. Likewise, basic properties of the powder such as melting temperature, degree of crystallisation and molar weight are not affected.Via a wide range of variable process parameters, many different coat properties can be achieved.
