The Huashida NBR PVC Flexible Rubber Foam Insulation Tube, Pipe, and Sheet Production Line is a high-performance industrial solution engineered for manufacturing flexible thermal insulation. This advanced extrusion line produces high-quality rubber foam pipes (sponge pipes) and insulation sheets utilized globally in HVAC and industrial sectors.

By integrating infrared radiation technology with a precision continuous vulcanization process, this equipment ensures a uniform closed-cell structure, superior thermal resistance, and high-speed output. The line is optimized for NBR (Nitrile-Butadiene Rubber) and PVC (Polyvinyl Chloride) formulations, delivering durable products for air conditioning, fitness equipment, and industrial piping.

Our thermal insulation manufacturing plant provides a full-cycle production workflow:

• Raw Material Prep: Rubber Cutter, Internal Mixer, Bucket Elevator, and Open Mill
• Extrusion & Foaming: High-precision Rubber Extruder with Infrared Foaming Stove and Hot Air Foaming Oven
• Finishing: Precision Traction System and Automatic High-Speed Cutting Equipment

1. Internal Mixing: Homogenizing NBR/PVC materials
2. Open Rolling: Precision material sheet preparation
3. Extrusion: High-torque shaping of the insulation profile
4. Continuous Foaming: Targeted heating to achieve closed-cell density
5. Cooling & Cutting: Final sizing and automatic length management

• Superior Efficiency: High-speed extrusion combined with low power consumption
• Intelligent Automation: Advanced PLC control reduces labor requirements by up to 30%
• Exceptional Quality: Continuous vulcanization ensures smooth surfaces and aging resistance
• Low Maintenance: Engineered with heavy-duty components for long-term durability
• Full Support: Lifelong technical assistance, commissioning, and on-site training

The resulting NBR/PVC insulation is characterized by low thermal conductivity, high moisture resistance, and excellent fireproofing. It is widely used for:

1. HVAC Systems: Thermal insulation for air conditioning pipes and refrigeration units
2. Industrial Utility: Protection for hot/cold water supply and technological vessels
3. Acoustic Solutions: Noise and vibration reduction for machine bodies and automotive parts
4. Fitness & Leisure: High-grade handles and protective sheaths for exercise equipment
