What cross-linking techniques are available?
The following cross-linking techniques are available: Peroxide cross-linking (PE-Xa) • Cross-linking achieved by reacting compound in peroxides at elevated temperatures • Cross-linking in an amorphous state ( > 136 degrees Celsius) • Homogeneous cross-linking over the entire wall thickness • Minimum degree of cross-linking required by Standards > = 70 % Silane cross-linking (PE-Xb) • Cross-linking via siloxane cross-linking groups • Achieved by chemical reaction between hot water/steam and PE silane co-polymer.
