The application of silicone masterbatch in low-smoke halogen-free cables is mainly reflected in its use as an additive in modified plastics and cable materials to improve material performance and safety.
Adding large amounts of flame retardants to low smoke halogen free cable materials can lead to high melt viscosity and high torque, which can affect processing performance. Silicone masterbatch can improve these properties, reduce torque and improve production efficiency.
As low smoke halogen free cable materials require a large number of additives, this leads directly to mechanical and processing performance challenges. For example, when using a single-screw extruder, over-shearing can lead to problems such as material breakdown and discoloration, while a twin-screw extruder has a higher mixing capacity, but also runs the risk of over-shearing.

Our product has following advantages:
1.Synergistic flame retardant effect: Silicone masterbatch is able to synergize with metal hydrates (e.g., magnesium hydroxide, aluminum hydroxide, etc.) to enhance the flame retardant properties of the material. This combination provides more effective fire protection while reducing the amount of flame retardant additives required, resulting in lower material costs and increased production efficiency.
2.Improved processability: Silicone masterbatch as a lubricant or rheology modifier can significantly reduce the extrusion torque of low-smoke, halogen-free materials, avoiding motor overload problems caused by high filler levels. This not only improves the operational stability of the production line, but also enhances overall production efficiency.
3.Enhance the surface quality of the finished product: Adding an appropriate amount of silicone masterbatch to the cable material can improve the smoothness, gloss and color brightness of the cable surface, as well as enhance abrasion resistance and scratch resistance. These properties result in a better appearance and service life of the final product.
4.Prevents “Sharkskin”: Silicone masterbatches added to polyethylene or cross-linked polyethylene compounds can effectively prevent “Sharkskin”, which is the formation of an uneven coating on the surface of a cable. This helps to ensure uniformity and consistency of the cable.
5.Reduced smoke generation: Compared to traditional red phosphorus flame retardants, silicone masterbatch is colorless, odorless and low-smoke, so it is environmentally friendly as it does not produce large amounts of smoke and noxious odors when burned.
6.Increased Yield and Productivity: By improving the processing flow of the material and reducing die buildup, silicone masterbatch enables wire and cable manufacturers to achieve higher yields and faster production speeds in high-speed extrusion processes without the concern of migration.
