application
low, middle and high density soft block polyurethane foam for packing and cushion materials.
feature
1. higher activity than mn-3050d. 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, indentation hardness and less permanent deformation than traditional soft foam. 3. has bht as antioxidant.
bht free and with strong anti-yellow capability
