Products Description

1.sound proofing

C8 is made of strong spongy material EPDM. In combination with double-side obturator foaming technology , it can make the sound-proof effect more perfect and more healthy. This product has strong environmental protection tasteless adhesive, and it is not glue to the hands, making the construction sequenceboth simple and strong.

2. Good fire –blocking

This product has fire-blocking and smoke-reducing property , when burned , its density is very low and doesn’t melt, without any small fire ball left and with the merit of self-extinguishing.

According to the standard of GBB8624-1997 Method for grading flammability of construction material, this is the flame resistant product of grade B1 enabling to secure the satiety

3.Low conductivity factor

Conductivity of this material is 0.034w/mk at an average°C.As this product has high heat-releasing ratio, it can get the same heat-preservation effect at less half thickness of other insulating product under the same condition, saving not only space but also cost.
