In the field of cable manufacturing, especially for low smoke zero halogen (LSZH) cable materials, the performance requirements are constantly increasing. Silicone masterbatch, as an important silicone-based additive, has been playing a significant role.
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.
Improve the extrusion rate of Wire & Cable compounds
One of the remarkable benefits of incorporating SILIKE Siloxane Additives SC920 into LSZH cable materials is the improvement in extrusion rate. During the cable production process, a faster extrusion rate means higher productivity. The unique rheological properties of silicone additives can reduce the viscosity of the compound, allowing it to flow more smoothly through the extrusion die. This not only shortens the production cycle time but also helps in reducing energy consumption. Manufacturers can produce more cable lengths within a given time frame, which is crucial for meeting market demands and reducing production costs.
Improved Filler Dispersion
Fillers are commonly used in cable materials to achieve certain mechanical and electrical properties. However, ensuring their uniform dispersion can be a challenge. SILIKE Processing Aids For LSZH Compounds Silicone masterbatch SC920 acts as an excellent dispersing agent. It coats the surface of fillers, preventing them from agglomerating. This homogeneous dispersion of fillers throughout the polymer matrix results in more consistent cable properties. For instance, it can enhance the tensile strength and elongation at break of the cable, making it more reliable in various applications. Moreover, better filler dispersion also contributes to the overall stability and quality of the cable material, reducing the likelihood of defects and performance degradation over time.
Enhanced Surface Abrasion and Scratch Resistance
The surface of cables often faces abrasion and scratching during installation, operation, and maintenance. SILIKE Silicone masterbatch SC920 can significantly improve the abrasion and scratch resistance of LSZH cable surfaces. The silicone component forms a protective layer on the cable surface, which has excellent flexibility and toughness. This layer can withstand mechanical rubbing and scratching, preventing damage to the underlying cable structure. As a result, the cable maintains its integrity and electrical performance for a longer period. It is especially important in applications where cables are exposed to harsh environments or frequent handling, such as in industrial settings, construction sites, and public transportation systems.
Improved Processing Lubricity
Another crucial aspect where SILIKE Processing Aids For LSZH Compounds Silicone masterbatch SC920 proves its worth is in enhancing the processing lubricity of cable materials. Firstly, it substantially improves the flowability of the compound. SILIKE silicone additives lower the internal friction within the material, enabling it to move more freely during processing. This enhanced flowability not only facilitates easier shaping and forming of the cable but also reduces the energy input required, leading to cost savings.
Secondly, SILIKE silicone masterbatch SC920 is very effective for Reduce die build-up. During continuous extrusion, materials tend to accumulate and solidify around the die, which can disrupt the production process, necessitate frequent stoppages for cleaning, and even affect the quality of the extruded cable. The lubricating action of the silicone additives SC920 prevents the adhesion of the cable material to the die surface, ensuring a smooth and uninterrupted extrusion process.
Moreover, it plays a significant role in Eliminate melt fracture. Melt fracture is a phenomenon that occurs when the polymer melt experiences unstable flow, leading to surface irregularities on the extruded product. These irregularities can compromise the cable’s electrical insulation properties and mechanical strength. The silicone masterbatch SC920 reducing the occurrence of melt fracture and ensuring the production of high-quality cables with smooth surfaces.
In conclusion, the application of SILIKE silicone masterbatch in low smoke zero halogen cable compounds offers multiple advantages. It addresses key challenges in cable production, from improving manufacturing efficiency through enhanced extrusion rate, ensuring long-term performance by enhancing filler dispersion and surface properties, to optimizing processing lubricity. As the cable industry continues to evolve and demand higher quality products, silicone masterbatch will undoubtedly remain a vital ingredient for achieving superior LSZH cable materials. With its unique combination of benefits, it not only meets the current technical requirements but also paves the way for further innovation in cable design and application.
