Frequently Asked Questions
What are the main advantages of using rubber foam insulation tubes?
The rubber foam insulation tubes offer low thermal conductivity, excellent fireproof properties, high vibration resistance, and a closed-pore foaming structure that provides outstanding moisture resistance. They are also flexible, easy to install, and provide great energy-saving benefits.
What temperature range can this insulation material withstand?
This material is rated to perform efficiently within a temperature range of -50°C to 110°C, making it suitable for both cooling and heating system applications.
What applications are these insulation tubes most commonly used for?
They are widely used for insulating chilled water pipes, condensation pipes, air ducts, and hot-water pipes in air-conditioning and HVAC equipment. They are popular in public buildings, industrial plants, clean rooms, and educational or medical facilities.
What is the raw material used, and how does it prevent moisture buildup?
The primary raw material is nitrile rubber. During production, it is foamed to create completely closed bubbles. This closed-cell structure acts as a built-in vapor barrier, effectively blocking moisture permeability.
What fire rating standard does the product meet?
The product achieves Class 0 and Class 1 fire ratings according to BS 476 Part 6 and Part 7 testing methods. It also meets the 25/50 standard for Flame Spread and Smoke Developed Index under ASTM E 84.
