OnCap™ Dry Silane Additives for Wire & Cable

If you need to crosslink polymers for wire and cable applications, please consider dry silane technology from Avient. Our OnCap™ dry silane additive formulations deliver both processing and product performance benefits.

Processing advantages include:

  • Easy-to-use
  • Cost effective
  • Low capital investment
  • Uniform cross-linking
  • Flexible; can be used with cross-linkable and standard thermoplastics on same line


And your end product also will see improvements too, such as:

  • Increased operating temperature limits
  • Improvements in mechanical properties, plus better resistance to oil and Abrasion


Dry silane formulations can be a cost-effective alternative to grafted compounds and other crosslinking techologies, and are more effective than peroxide crosslinking for manufacturing low voltage cable at high output. 

Dry silane technology is a two-component formulation consisting of a silane mixture in a porous polyolefin carrier. The technology adds value to many of the materials used in manufacturing wire and cable, including:

  • LDPE
  • HDPE
  • MDPE
  • EVA
  • ECCOH™ LSFOH solutions



  • Develop with confidence: Benefit from the experience of our global W&C materials development team
  • Application-specific solutions: Dry silane can be used with the polymers commonly processed in the wire and cable industry
  • Enhance functional properties of the end product including:
    • Increased operating temperature limits
    • Improved mechanical properties
    • Enhanced oil resistance
    • Improved abrasion resistance
