XL-PEarl™ Silane Crosslinking Systems

XL-PEarl crosslinking systems may help compounders to optimize cost-effectiveness because of their versatility, stability and ease of processing. They are designed for use with nearly any polyethylene grade: high-, medium-, low- or linear low-density polyethylene (HDPE, MDPE, LDPE, LLDPE). They can also accommodate new single-site catalyst resins. The stability of XL-PEarl crosslinking systems is reflected in a high SADT (self-accelerating decomposition temperature), and means that safe shipment and handling of XL-PEarl crosslinking systems don't require costly, specialized consideration. 

Comparing XL-PEarl crosslinking system blend technology with standard crosslinking agents, XL-PEarl crosslinking system-based master batches may exhibit less sensitivity to moisture. Special stabilizers in the XL-PEarl master batch formulation prevent premature polymerization of the grafting agent and provide excellent aging properties of crosslinked polyethylene. A higher speed line is also possible due to an increased processing window and reduced die pressure.

End products manufactured using XL-PEarl technology normally exhibit a premium surface finish, superior mechanical properties and excellent chemical resistance, and may withstand continuous exposure to temperatures up to 110˚ C under certain conditions. Depending on the individual blend selected, XL-PEarl products may help produce oil-and-gas-resistant piping for transmission purposes, and they are qualified to serve as potable water pipes.

Compounds created with XL-PEarl crosslinking systems can be tailored for pipe, cable and wire jacketing applications in the automotive, building and construction, water and heating utilities, electrical transmission and distribution, electronics, transportation, and aerospace industries.
