Royflexa Rubber
1 / 5
Our HVAC Foam Rubber Insulation Sheets are a flexible and durable insulation solution made from high-quality NBR/PVC (Nitrile Butadiene Rubber and Polyvinyl Chloride). It is specifically designed to deliver outstanding thermal insulation for pipes and ductwork in HVAC systems.
Ideal for both hot and cold water lines, air conditioning systems, and refrigeration applications, this insulation tube helps maintain consistent temperatures within the system, significantly reducing energy loss and enhancing operational efficiency.
Manufactured using a specialized foaming process, these Insulation Sheets feature a fully closed-cell structure. This design provides superior thermal insulation performance, excellent moisture resistance, and long-lasting durability—even in high-humidity or high-temperature environments.
We offer a wide range of rubber foam insulation products with various materials, surface finishes, and color options. Designed to adapt flexibly to diverse customer requirements, our insulation solutions ensure excellent performance while meeting aesthetic and functional needs.
Key Features:
Applications: Widely used in HVAC systems (copper pipe, ductwork insulation), refrigeration pipelines, chilled water piping, and industrial fluid transport systems.

| No. | Guideline | Description |
|---|---|---|
| 1 | Seal Seams and Joints | Use adhesive to ensure airtight bonding at all seams and joints. |
| 2 | Insulate Fittings | Insulate all tees, elbows, valves, and flanges to the specified thickness. |
| 3 | Avoid Excessive Pressure | Gently compress interfaces when applying adhesive. Avoid too much pressure. |
| 4 | Installation Order | Large pipes → small pipes → elbows/tees → straight sections → valves/flanges. |
| 5 | Bonding at Gaps | Fill and bond gaps between rubber tubes and metal pipes (width ≥ insulation thickness). |
| 6 | Seam Positioning | Position seams in inconspicuous areas and stagger adjacent seams. |
| 7 | System Operation | Do not install while system is running. Wait 36 hours before starting. |
| 8 | Large Tube Cutting | Cut along the flatter side of oval tubes for easier installation. |
