The raw materials mainly used in the traditional cable industry include copper and aluminum as conductor materials, and rubber, polyethylene, polyvinyl chloride as insulation and sheathing materials. These traditional insulating sheathing materials will produce a large number of toxic fumes and corrosive gases when burned, causing harm to the environment and human health.
With the increase of environmental protection and safety awareness, the emergence of low-smoke halogen-free flame retardants has brought revolutionary changes to the cable industry, providing safer and more environmentally friendly alternative materials.
The use of low-smoke halogen-free flame retardants in the cable material industry has had a significant impact and change on the entire industry. First of all, the use of low-smoke halogen-free flame retardants meets the requirements of modern environmental protection and safety, because they produce less smoke and toxic gases when burning, thus reducing the harm to people and the environment in the case of fire. In addition, with the global restrictions and cancellation of PVC materials, low-smoke halogen-free cable materials have gradually become the mainstream of market development.
How to solve the processing problems brought by low smoke halogen-free flame retardants for the cable material industry
However, the trend toward LOW smoke halogen-free flame retardants has placed new processing demands on wire and cable manufacturers. The new wire and cable compounds are heavily loaded and can create issues with processing release, die drool, poor surface quality, and pigment/filler dispersion. Incorporating SILIKE LYSI series silicone masterbatch significantly improves the material flow, extrusion process.
SILIKE LYSI series silicone additives are based on different resins to ensure optimum compatibility with the thermoplastic. SILIKE LYSI series silicone masterbatch are widely used in LSZH/HFFR wire and cable compounds, silane crossing linking XLPE compounds, TPE wire, Low smoke & low COF PVC compounds. Making wire and cable products eco-friendly, safer, and stronger for better end-use performance.
Silicone processing aid SC 920 is a special silicone processing aid for LSZH and HFFR cable materials which is a product composed of special functional groups of polyolefins and co-polysiloxane. The polysiloxane in this product can play a anchoring role in the substrate after copolymerization modification, so that the compatibility with the substrate is better, and it is easier to disperse, and the binding force is stronger, and then give the substrate more excellent performance. It is applied to improve the processing performance of materials in LSZH and HFFR system, and is suitable for high-speed extruded cables, improve output, and prevent the extrusion phenomenon such as unstable wire diameter and screw slip.
Adding 0.5 to 2% of SILIKE silicone masterbatch SC920:
- Improved processing and flow
- Less extruder torque
- Lower die pressure
- Reduced die drool and melt fracture
- Faster throughput
- Better melt flow
Adding 1 to 5% of SILIKE silicone masterbatch SC920:
- Improved surface lubricity and slip
- Lower coefficient of friction
- Better abrasion resistance
- Better surface touch and feel
Incorporating SILIKE LYSI series silicone masterbatch significantly improves the material flow, extrusion process, slip surface touch and feel. The use of SILIKE special cable material processing additives not only solves the production and processing problems of cable materials, but also promotes the development of the entire industry to higher performance.
