For application,as the molecular weight of the polyolincreases,the elongation at break gradually increases while the tensile strength and hardness decreases.Customers may choose polyether polyols of different molecular weight according to their final product’s request.They can also arrange MN-3050DF,EP-330NG or EP-3600 in groups to increase the product’s tensile strength.TrademarkHydroxylValuemgKOH/GAcidValuemgKOH/GWaterContent%pHUnsaturatedValuemol/kgViscositymPa·s/25℃K﹢mg/kgColourityAPHAFunction-alityMolecu-lar weightEP-330N(G)32.5-35.5≤0.05≤0.055-7≤0.07800-1000≤3≤5035000Application and FeatureWith a functionality of 3 and monlecular weight of 5000,this kind of high-activity polyether polyol can be used for polyurethane adhesive produces,which can effectively increase the tensile strength and the resilience. |
