Product Description

    Formulated Silane SLF-13(Equivalent to SILFIN13 silane)

 

 

Description

Formulated Silane SLF-13 is designed for use in two-step like Sioplas Process silane-crosslinking of polyethylene and ethylene copolymers for the power cable industry.
Performance properties of silane-crosslinked polyethylene can meet or exceed those of peroxide-crosslinked polyethylene, which offering advantages in boarder processing latitude and lower fabrication costs.
Formulated Silane SLF-13 is a clear yellowish liquid which only contains: vinyl silane and grafting-initiator. Its crosslinking vinylsilane incorporates grafting in a ratio suitable for crosslinking polyethylene in commercially available extrusion equipment.

Reaction Sequence

Formulated Silane SLF-13 is suitable for the preparation of moisture-curing polymers. The characteristic feature of this process is grafting of the vinylsilane 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 our in a waterbath (80ºC~100ºC), steambath or even at ambient conditions, the polymer chains are linked together, thereby forming a crosslinking polymer. This reaction is accelerated by using a catalyst.
Formulated Silane SLF-13 contains only the constituents which are necessary for grafting. The catalyst necessary for the crosslinking step can be added as a masterbatch to the grafted polymer, just before the finishing step.
Polyethylene, crosslinking with Formulated Silane SLF-13, is mainly used for the production of power cables in a two- step Sioplas Process.

4.Packing Details of the Formulated Silane SLF-13 :
The regular packing of Formulated Silane SLF-13 is 25kg plastic pail, 200L steel drums and 1000L immediate bulk container.
 
5.Storage and Shelf Life of Formulated Silane SLF-13:
Should be stored in dry, cool, ventilated room; keep away from water, moisture, high temperature and fire. This product has a shelf life of at least 12 months if stored in tightly closed original container at room temperature. 
If this product is kept beyond the shelf life recommend on the product label, it is not necessarily unusable, but a quality control should be performed on the properties relevant to the application.
