Product Description
Description
Formulated Silane SLF-13 (the equivalent product to Silfin 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 (the equivalent product to Silfin 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.

Useful with filled composites
Reaction Sequence
Formulated Silane SLF-13 (the equivalent product to Silfin 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 (80 C~100 C), 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 (the equivalent product to Silfin 13) is mainly used for the production of power cables in a two- step Sioplas Process.
Packing
The regular packing of this product is 25L PE pail, 200L steel drum and 1000L PE IBC.
Product Safety and Handling
Customer considering the use of this product should review the latest Material Safety Data Sheet and label for product safety information. Handling instructions, personal protective equipment if necessary, and any special storage conditions required. Use of other material in conjunction with capatue performance materials products (for example, printers) may require addition precautions. Please review and follow the safety information provided by the manufacturer of such other materials.
Storage and Shelf Life
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 9 months if stored in tightly closed original container at room temperature.
CAUTION: NEVER STORE THIS PRODUCT ABOVE 55C (131F)!
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.
