Closed Cell Tubing, Sheet and Roll Insulation


Density Test

Flame Retardant Test

Smoke Density Test

Hardness Test

Batch Oven


The extreme flexibility of the material makes installation fast, easy and economical

Dust, fiber free and resistance to fungus growth

Low thermal conductivity (‘K’ Value) which makes it highly efficient and effective in the insulation of cooling or heating system

Self extinguished in nature

Closed cell structure forms a good water vapor barrier

Able to withstand tearing, rough handling and severe site conditions

Tensile Stress

Tensile strength to 3 Mpa,
hardness 55-80 density
which provide safety and
longer life span

Fire Resistance

Tested and conformed
to British Standard BS476:
Part 6 & 7

Thermal Insulating

Closed cell structure, thermal
conductivity 0.038W/mK,
conforms to ASTM C534

Water Resistance

Negligible water absorption
due to closed cell structure

Environment Friendly

Environment Friendly can be handling at anytime,
unlike five board system which is very
dusty during cutting



Refrigerant Media

Good flexibility, easy installation and operation, applicable to the field of air conditioning refrigerant heat medium system brass

Chilled Water System

Excellent thermal insulation properties, can effectively prevent condensation generated, so air conditioning system performance significantly

Hot Water Piping System

Good insulation properties, soft and easy to install, so that less heat loss, more convenient installation

Ventilation Ductwork

Also comply with stringent multinational world fire standard. Greatly enhance the safety performance of the material for iron metal pipe thermal insulation field

Condensate System

Excellent resistance to water vapor permeability, softer and easy to install, suitable for condensing water pipe systems.

Sound absorbing sheet is divided into flat and concave – convex surface, it mainly plays the role of sound absorption, vibration and noise reduction

Act as good protection pads for walls and floors, safety for public area

Rubber foam insulation board are widely used in the heat protection for roofing
