DEP-5631D	54.5-57.5	≤0.05	≤0.05	5-7	≤0.01	400-700	-	-	Low, middle and high density soft block Polyurethane foam for packing and cushion materials.	1. Higher activity than MN3050D. When produce low density foam ,it less prone to collapse bubbles, cracks and other abnormal defects. 2. with low unsaturated value and average functionality over 2.9,the foam made by it has higher tensile strength and indentation hardness, and less permanent deformation than traditional soft foam. 3. Has antioxidant of BHT.
DEP-5631ED	54.5-57.5	≤0.05	≤0.05	5-7	≤0.01	400-700	-	-		Without BHT and with strong anti-yellow capability
MN-3050D	54.5-57.5	≤0.05	≤0.05	5-7	≤0.01	400-700	-	-	Middle and high density soft block polyurethane foams for packing and cushion materials.	1. less activity than DEP-5631D and not fit for low density form. When be used in wide middle and high density foam, it is easier for users to adjust the formula. 2. with low unsaturated value and average functionality over 2.9,the foam made by it has higher tensile strength and indentation hardness, and less permanent deformation than traditional soft foam. 3. Has antioxidant of BHT.
EP-455S	43.5-46.5	≤0.05	≤0.05	5-7	≤0.05	550-750	≤3	≤50	extra soft block foam for packing, cushion material	PO and EO PPG of 3500 molecular weight. Soft polyurethane block foam made from it could obviously promote softness and comfort
