Huashida's Rubber Foam Insulation Tube/Sheet Production Line is developed with advanced technology, making it the ideal choice for producing high-quality rubber foam insulation materials (commonly known as "sponge pipes" or "rubber-plastic insulation pipes"). This production line features an automatic control system and self-developed key technologies, utilizing high-quality core components to ensure both production efficiency and product performance lead the industry.

Product Overview & Forms
The rubber foam insulation material efficiently manufactured by this production line is primarily made from acrylonitrile-butadiene rubber (NBR) and polyvinyl chloride (PVC), along with a variety of high-quality auxiliary materials. The entire process uses advanced extrusion and foaming techniques and is completely free of chlorofluorocarbons (CFCs), adhering to green environmental standards.

The products can be flexibly produced in two main forms:

Rubber Foam Insulation Tubes (for pipe insulation)

Rubber Foam Insulation Sheets (for flat surfaces or container insulation)

Exceptional Performance of Rubber Foam Insulation Materials
The rubber foam insulation materials produced by this line possess a range of superior properties, making them excel in various applications:

Excellent Softness: Easy to install and process, adapting to complex structures.

High Flexibility: Outstanding bend resistance, preventing damage.

Cold & Heat Resistance: Maintains stable performance under extreme temperature conditions.

Superior Flame Retardancy: Enhances safety in construction and industrial applications.

Waterproof & Moisture-Proof: Effectively prevents moisture penetration, maintaining insulation effectiveness.

Low Thermal Conductivity: Significantly reduces heat loss or cold gain, enabling high energy efficiency.

Shock Absorption & Sound Absorption: Helps reduce equipment operating noise and vibration.

Due to their excellent comprehensive properties, rubber foam insulation materials are widely used across multiple critical industries and sectors, effectively minimizing both cold and heat loss:

Industrial Facilities: For thermal insulation of pipes, vessels, and other technological containers.

Central Air-Conditioning Systems: Insulation for pipes and equipment, greatly reducing cooling loss.

Construction & Heating Systems: Suitable for insulation of cold/hot water supply and heating system pipes.

Noise & Vibration Control: Applied as coatings on machine parts or equipment bodies to effectively reduce noise and vibration.

Specialized Applications: Used in industries like chemical, pharmaceutical, textile, metallurgy, shipbuilding, vehicles, and appliances. Also ideal for high-grade handles/sheaths on fitness equipment, medical equipment, and for indoor/outdoor pipe insulation in solar heating systems.

Latest Technology, Fully Automatic Continuous Production: Ensuring highly efficient and stable manufacturing.

Superior Performance Compared to Similar Lines: Our equipment offers distinct advantages in key technologies and product performance.

Automatic Temperature Control, Low Energy Consumption: Intelligent control systems effectively reduce energy consumption.
