Silicone Masterbatch SC920 Improve Processability And Productivity In LSZH and HFFR cable materials

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.

Benefits

1, When applied to the LSZH and HFFR system, can improve the extrusion process of the mouth die accumulation, suitable for high-speed extrusion of the cable, improve production, prevent the diameter of the line instability, screw slip and other extrusion phenomenon.

2, Significantly improve the processing flowability, reduce the melt viscosity in the production process of high-filled halogen-free flame-retardant materials, reduce torque and processing current, reduce equipment wear, reduce product defect rate.

3, Reduce the accumulation of die head, reduce the processing temperature, eliminate melt rupture and the decomposition of raw materials caused by high processing temperature, make the surface of the extruded wire and cable smoother and brighter, reduce the friction coefficient of the surface of the product, improve the smooth performance, improve the surface luster, give smooth feel, improve scratch resistance.

4, With special modified silicone polymer as the active ingredient, improve the dispersion of flame retardants in the system, provide with good stability and non-migration.

How to use

After mixing SC 920 with resin in proportion, it can be formed directly or used after granulation. Recommended addition amount: When the addition amount is 0.5%-2.0%, it can improve the processability, fluidity and release of the product; When the addition amount is 1.0%-5.0%, the surface properties of the product can be improved (smoothness, finish, scratch resistance, wear resistance, etc.)
