Rubber Kneader Internal Mixer
Heat Protection Silicone Rubber Heating Belt Production Line – Factory Direct Price Product.
Overview This production line manufactures thermal protection silicone rubber heating belts — a flexible, high-performance heating solution built from nickel-chromium alloy resistance wire encased in insulating silicone rubber.
Engineered for high power density, rapid heat-up, high thermal efficiency, and long service life, the finished belts are ideal for both general constant-power heat tracing and dedicated heating applications.
The silicone rubber heating belt offers excellent waterproof performance, making it suitable for use in humid, non-explosive industrial and laboratory environments — including pipelines, tanks, and vessels. It wraps directly around the surface of the equipment being heated, allowing for fast, simple, and safe installation.
Key Applications
• Hot water pipe insulation, freeze protection, and de-icing/snow-melting in cold-climate regions • Solar water heater pipeline heat tracing
• Heat tracing and insulation for industrial equipment and laboratory pipelines, tanks, and vessels in humid, non-hazardous environments Product Features
• High temperature resistance
• Excellent cold resistance
• Strong aging/weathering resistance • Waterproof and moisture-resistant • High thermal efficiency with fast heat-up • Long operational lifespan • Simple, flexible installation — wraps directly onto pipes/equipment
Production Line Process 1. Rubber Refining — Kneader → Open mixing mill → Batch-off cooler 2. Extrusion — Resistance wire and rubber are co-molded via extruder 3. Cutting & Stripping — Belt is cut to fixed lengths; both ends are stripped by hand or machine to expose the resistance wire 4. Vulcanization — Both ends are vulcanized using a vulcanizing press for a sealed, durable finish
