WIDE RPEFLEX utilizes international lastest rubber and plastic modifying technology, introduces world-class permanent aluminum foil composite technology and equipment, are equipped with rubber and plastic composite heat insulation material, which steps international advanced level 's.Its main raw materials are polyethylene and EPDM, without PVC, low toxic and smoke, safe and trustful.Heat preservation and separate air is improved, and it is rubber plastic foaming material upgrade and renew product.
100% independent closed-bubble structure
The material has 100% independent micro-air bulb structure.The air bulb's average diameter is only about 50?.
Heating conductivity:0.0327W/m.K(average temperature 10 degree celsius ).
Moisture resistance factor e 30000 (GB/T17794 -1999).After utilizing aluminum foil composite technology, which makes good use of the wet resistance performance.
Water absorption rate is 3%, and heat preservation layer external water absorption rate is 0.
Surface thermal conductance
The special surface burst square structure, which improve surface's roughness, increase heat exchange area, compared to other heat preservation material, increase by 20%.It improves material surface thermal conductance, from 8.146 up to about 10, effectively reduce use thickness of anti- dewfall.
It is convenient for construction and pretty appearance.
Good surface quality and long service life
The composite high strength aluminum foil slows down the material aging speed, completely avoids the surface crack defect of the rubber and plastic material, so largely improves material service life.
Good combustion performance, safety and non-toxicity
The combustion performance meet international GB8624-1997B1 class requirements, and it plasters no burning aluminum foil, which further improves fireproofing performance of heat preservation layer.The material comprises of No-PVC, the gas caused by combustion is not including HCN and HC1 toxic gas etc.It is the only material, whose smoke toxicity is in conformity in GA132-1996 and ZA2.
Environmental protection, healthiness and wide use range
It's no toxicity and easy installation, and it is used widely.
