Huashida's Rubber Foam Insulation Tube and Sheet Production Line is designed to manufacture high-quality rubber-plastic insulation materials. Equipped with an automatic control system, advanced technology, and quality components, it ensures efficient operation, stable production, and consistent product quality.
The line uses NBR, PVC, and other additives, applying extrusion and foaming technology to produce flexible, closed-cell insulation materials. CFC-free processing is available according to production requirements.

The production line features high extrusion efficiency, a high level of automation, and excellent operational safety. Its advanced design and manufacturing technology ensure stable production, reliable vulcanization quality, and consistent product performance.
The rubber foam insulation materials produced feature a closed-cell structure with excellent flexibility, bending resistance, low-temperature resistance, heat resistance, flame retardancy, water resistance, low thermal conductivity, shock absorption, and sound absorption. These properties make them high-performance materials for thermal insulation and energy-saving applications.
The products are widely used for thermal insulation in central air-conditioning systems, buildings, chemical and pharmaceutical industries, textile and metallurgical facilities, ships, vehicles, and electrical appliances.
Suitable for insulating hot and cold medium pipelines and containers, the products help reduce heat transfer, minimize energy loss, and improve the overall energy efficiency of equipment and piping systems.
