Composite Plastic Blocks Type	Interval (Minutes)
	2.00	4,00	6,00	8,00	10.00
100% MLP	Fire ignites and extinguishes	Melting without flame	Flames getting immense	Melting and sparkling	100& surface melting and flaming
MLP + SD	No physical changes	No physical changes	It starts to produce smoke and flame	Flames getting big	Some surface melting
MLP + SA	No physical changes	No physical changes	No physical changes	Start to produce thin smoke	It still has light smoke and no changes
MLP + CS	Emitting thin smoke	Starting to melt slowly	No flames	No further changes	No further changes
