Huashida's rubber foam insulation tube/sheet production line utilizes cutting-edge technology, specifically engineered to produce high-quality rubber foam insulation materials (also known as "sponge pipes" or "rubber-plastic insulation pipes"). Equipped with an automatic control system and leveraging proprietary core technologies, our line integrates premium components to ensure superior production efficiency and product performance.

This advanced production line efficiently manufactures rubber foam insulation from a combination of acrylonitrile-butadiene rubber (NBR), polyvinyl chloride (PVC), and high-grade auxiliary materials. The process employs sophisticated extrusion and foaming techniques and is completely CFC-free, demonstrating our strong commitment to environmental responsibility.

Our line primarily produces insulation in two forms:

Rubber Foam Insulation Tubes: Ideal for insulating pipes.

Rubber Foam Insulation Sheets: Perfect for insulating flat surfaces or containers.

The insulation materials produced on our line boast a comprehensive set of outstanding properties:

Exceptional Flexibility: Soft, highly bendable, and easy to install, adapting to complex geometries.

Thermal Resilience: Maintains stable performance across a wide range of temperatures, offering excellent cold and heat resistance.

Enhanced Safety: Exhibits superior flame retardancy.

Moisture Protection: Features strong waterproof and moisture-proof characteristics, preserving insulation effectiveness.

Energy Efficiency: Possesses low thermal conductivity, significantly reducing heat loss or gain.

Noise & Vibration Reduction: Contributes to quieter environments by absorbing shocks and sounds.

Extensive Application Spectrum
Our rubber foam insulation materials are widely deployed across numerous critical industries, effectively minimizing energy waste from temperature fluctuations:

Industrial Facilities: Essential for the thermal insulation of pipes, vessels, and various processing equipment.

HVAC & Climate Control: Crucial for insulating pipes and equipment in central air-conditioning and heating/cooling systems, significantly cutting energy loss.

Construction: Provides reliable insulation for cold/hot water supply lines and heating system pipes.

Acoustic & Vibration Dampening: Utilized as coatings on machine parts or equipment for effective noise and vibration reduction.

Diverse Sectors: Found in chemical, pharmaceutical, textile, metallurgy, shipbuilding, vehicle, and appliance industries. Also applied in specialized products like high-grade handles/sleeves for fitness and medical equipment, and for indoor/outdoor piping in solar heating systems.

Our state-of-the-art production line comprises essential equipment ensuring continuous and automated manufacturing:

Rubber Cutter: For precise raw material preparation.

Internal Mixer: Ensures thorough blending of rubber and auxiliary compounds.

Bucket Elevator: Facilitates efficient material transfer.

Open Mill: Processes materials to enhance uniformity and plasticity.

Rubber Extruder: Shapes the mixed materials into tubes or sheets.

Transition Roller: Guides material smoothly into heating stages.

Infrared Foaming Stove: Initiates the foaming process with controlled heat.

Hot Air Foaming Stove: Completes uniform foaming, establishing the insulation's porous structure.

Tractor and Automatic Cutting Equipment: Provides stable pulling and precise final product cutting.
