Description

Black rubber insulation gives a practical insulation layer for pipes, ducts, equipment shells, valve boxes, and chilled water rooms. It is not selected by one number only because thickness, density or grade, facing, and joint treatment all affect the finished work. When the route includes corners, flanges, hanging rods, or narrow wall spaces, the product is prepared around general HVAC condensation control and the installation method.

Installation Notes

Fit black rubber insulation after the support position is confirmed. A moved hanger or bracket can change the required cut size.

Press the material evenly instead of pulling one edge too hard. Uneven tension can leave a thin area at the corner.

Keep the same seam direction on one route when possible, so the finished surface is easier to check.

Certifications & Qualifications

For black rubber insulation, select the rubber plastic sheet conformity document when the supplied item is sheet, board, or duct surface insulation.

Product conformity document: UDEM Technical Inspection Attestation of Conformity for Rubber Plastic Sheet, related standard EN 14304:2015, certificate No. M.2025.206.C125163, report No. TCF-OY20250812-EN-04.

Certificate model: Xinyafeng/800*1500*25mm. If the final item is pipe insulation or another shaped part, the certificate name should be checked before use.

TDS, MSDS, certificate image, packing list, and customs documents can be supplied when required.

FAQ

Q: Why is sealing important for black rubber insulation?

A: Rubber insulation works only when seams are closed. Open joints may collect moisture and form condensation marks.

Q: What should be watched when installing black rubber insulation?

A: Keep the surface clean, avoid sharp burrs, close seams, and leave access covers or labels visible if the drawing needs them.

Q: Is facing always required?

A: Not always. Facing depends on visible surface, moisture control, fire report, and whether the material needs easier cleaning or taping.
