Melamine foam testing

	Unit	Result	Test standard
Density	Kg/m3	8-11	EN 1936
Hardness	F0	65-85	KS M 6518
Tensile strength	KPa	110-160	GB/T 6344-2008
Muffling coefficient	NRC	0.95	ISO 354:2003
Thermal conductivity	W/(m . K)	0.034	GB/T 10295-2008
heat resistance	(m2 . K)/W	2.310	GB/T 10295-2008
Flame Rating	Rate	B1 (B-S1, d0)	GB 8624-2012

Compared with fiberglass, mineral wool, melamine foam also have super soundproof performance.

Item	Fire retardant	Density	Sound absorption	Heat stability	Environmental Protection
Melamine foam	Flame rating is B1(without any retardant)	6-12kg/m3	Obvious advantage of medium and high frequency sound absorption	Can resist under -20 ℃-200 ℃ for a long time	Environment friendly
Fiberglass	Flame rating is A	≥35kg/m3	medium and high frequency	Working condition -50℃-180 ℃	Easy degradation, flying dust
Mineral wool	Flame rating is A	≥35kg/m3	medium and high frequency	Working condition -50℃-180 ℃	Easy degradation, flying dust and carcinogenic
