Enhance High-Speed Extrusion & Prevent Die Build-Up with SC 930 Silicone Additive for LSZH & HFFR Cables

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 LSZH and HFFR systems, SC 930 improves the extrusion process by reducing die build-up, making it ideal for high-speed cable extrusion. It enhances production efficiency and prevents issues such as inconsistent wire diameter, screw slip, and other extrusion problems.
2. SC 930 significantly improves processing flowability by reducing melt viscosity during the production of high-filled halogen-free flame-retardant materials. This reduces torque, processing current, and equipment wear, while also lowering the product defect rate.
3. SC 930 minimizes die head accumulation, lowers processing temperatures, and prevents melt rupture or material decomposition caused by excessive heat. It enhances the surface finish of extruded wires and cables, making them smoother and shinier. Additionally, it reduces the friction coefficient, improving surface smoothness, scratch resistance, and tactile feel.
4. With specially modified silicone polymers as the active ingredient, SC 930 enhances the dispersion of flame retardants in the system, providing excellent stability and preventing migration.

How to use

After mixing SC 930 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.)
