Low Unsaturation 400-4000 Molecular Weight Propylene Oxide Ether Diol, Can Be Used in Various PolvuRethane Waterproof Series Products, As A Basic Component OfThe Soft Segment Structure Of PolyurethaNe Products. Dl Series Products Are Mainly For Case Series Products, The Molecular Weight ls Extended From 400 To 4000. in The Specific Application, As The Molecular Weight Of Polyether increases, The Elon Gation At Break Of The Product Increases Gradually, The Tensile Strength Decreases GraduallyAnd The HArdness OfThe Product Gradually Decreases, Customers Can Choose Different Molecular Weight Produc Ts According To Their Own Products, And Can Also Be Used With Mn-3050df/ep-3600ng/ep-3600/10ld76eAnd 10ld83e To lmprove The Tensile Strength OfThe Product.
