NBR PVC Flexible Rubber Foam Insulation Tube, Pipe and Sheet Production Line
The Huashida NBR PVC Flexible Rubber Foam Insulation Tube, Pipe and Sheet Production Line is a high-performance industrial solution engineered for the manufacturing of 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.
