Product Overview

B1‑grade colored elastomeric rubber‑plastic insulation tube is made of dyed NBR nitrile‑rubber foamed substrate. Red and blue colors are available for pipeline identification. Red for hot‑water pipes and blue for cold‑water pipes. It combines thermal insulation and pipeline marking functions, widely used in HVAC and plumbing systems.

Key Performance

1.Thermal Insulation & Condensation Prevention Closed‑cell foam structure with low thermal conductivity, blocking heat transfer and avoiding pipe condensation to reduce energy loss.

2.Color‑Coded for Easy Maintenance Red‑blue color distinguishes hot and cold pipelines without extra painting. Simplify construction and improve identification efficiency for later inspection.

3.Excellent Flexibility for Pipe Fitting Soft and elastic material fits closely with various pipes of different diameters for convenient installation.

4.Moisture & Water Resistance Closed‑cell foam resists water‑vapor penetration to maintain long‑term insulation performance.

5.Fire Safety B1‑grade flame‑retardant, self‑extinguishing with few burning drips, complying with building fire‑protection standards.
