Product Overview

B1‑grade black elastomeric rubber‑plastic insulation tube is tubular thermal insulation material manufactured from closed‑cell NBR nitrile‑rubber foam. Flexible and bendable for various metal pipes. Widely used in HVAC, refrigeration and plumbing systems.

Key Performance

1.Thermal Insulation & Condensation Prevention 

Fine closed‑cell foam features low thermal conductivity. Blocks heat transfer and avoids pipe‑surface condensation to reduce energy loss.

2.Excellent Flexibility 

High elasticity allows free bending. Fits elbows and irregular pipelines without cracking.

3.Moisture & Vapor Resistance 

Closed‑cell structure inhibits water‑vapor penetration, maintaining stable long‑term insulation performance.

4.Convenient Construction 

Easy cutting. Can be sleeved directly or slit for wrapping installation to improve working efficiency.

5.Fire Safety 

B1‑grade flame‑retardant, self‑extinguishing with minimal burning drips, compliant with building fire‑protection requirements.

6.Vibration & Noise Reduction 

Foamed material absorbs vibration and lowers operating noise of pipelines.
