Product Description

Formulated silane equiv. to Silcat R
 

Abstract

Formulated silane (also called as silane cocktail) SLC-R is a high speed silane formula from Capatue which is designed for use in one-step Monosil process, Spherisil Process and Soaking Compound Process silane-crosslinking of PE and ethylene copolymers for the power cable industry.
Formulated Silane SLC-R is a clear, colorless to yellow liquid (the product can darken) which contains: vinyl silane, peroxide grafting-initiator and tin catalyst (for moisture cure). Its crosslinking vinyl silane incorporates grafting and crosslinking catalysts in a ratio suitable for crosslinking polyethylene in commercially available extrusion equipment. Formulated Silane SLC-R modifies polyethylene resins chemically during melt processing (i.e., extrusion) and efforts polymer crosslinking upon exposure of the fabricate polyethylene to moisture.

Benefits of Silane XLPE

The heat resistance is the main reason for using silane XLPE in the cable & wire and pipe application. Furthermore crosslinking can also improve the following properties of the polymer:
Chemical resistance
Impact strength and tensile strength
Aging resistance
Creep resistance under load
Abrasion resistance
Memory effect

 

Reactivity

The following reactions describe the basic chemistry:

Formulated silane SLC-R is suitable for the preparation of moisture-curing polymers. The characteristic feature of this process is grafting of the vinyl silane to the polymer during extrusion.
After the grafting, the polymer can still be processed as a thermoplastic. Only during treatment with moisture which is usually carried out in a water bath (80ºC~100ºC), steam bath or even at ambient conditions, the polymer chains are linked together, thereby forming a crosslinking polymer. This reaction is accelerated by using a catalyst. SLC-R contains the constituents which are necessary for both steps.
