1.8 years experience 2.Credible quality 3.Delivery in time 4.Long life time 5.Ensured performance

Introduction:

Polyethylene closed-cell foam plate is also called joint filler board, which is a new type of joint water-stop material in China. It has been repeated proved by China's Ministry of Communications Academy of Sciences that the performance is much better than wood, cork, rubber, asphalt.

Features:

Low surface bibulous rate, good performance of anti osmosisResistance to solvent corrosion like acid, alkali, salt, oil, etc. Good performance of ageing resistance Not flow in high temperature, not embrittle in low temperature Closed sell  prevents water absorptionEasily worked  can be cut with knifeStructural expansion in concrete brickHigh density withstand  hydrostratic pressureExcellent and quick recovery after compression  

Technical Data:

Physical Properperties
Density	60kg/m3
Tensile Strength	3.75kg/cm2
Tear Strength	3.10kg/cm2
Water Absorption	0.02% Volume
Operating Temperature	40°C to 70°C
Recovery at 50% compression	Average -98%
Bacteriological attack resistance	Excellent

 Application:

Concrete highway expansion joint,

Road and bridge,

Water conservancy project: dam, protecting beach, baffle bar, slope protection,

Water and electricity engineering, thermal power engineering, water tower bottom water-stop,

Airfield ,runway,

Port, wharf,

Water tunnel, tunnel,

Subway, underground passage.

With the unique advantages of strong recovery rate, no water absorption, water impact resistance, weather resistance, chemical resistance and aging resistance, Polyethylene closed-cell foam plate is becoming more and more widely used, without which for other materials.

Storage:

 Stored in dry and ventilated places, prevent sunlight and rain, stack separately for different categories and specifications, keep flat, the height should not be more than 5 layer.
