Polycomp XL 6400 is a silane grafted, moisture curable, linear low density polyethylene that has been formulated for low voltage electrical cable applications to meet AS3808, Table 9, Criteria 2 (X-90) requirements. It does not contain UV stabilization. For outdoor applications, a suitable anti-UV package and/or high loading of carbon black (³2.5%) should be added in order to fulfill the weatherability requirements.

It requires the addition of 5% of a catalyst masterbatch Improve XL 8705 HS just prior to extrusion to accelerate the moisture induced crosslinking reaction. Mixing with the catalyst masterbatch, Improve XL 8705 HS, @ 5% just prior to processing accelerates the moisture induced crosslinking reaction which occurs rapidly in sauna or hot water conditioning and more slowly under ambient conditions.
