Main Application
HQEE is a new-style poisonless chain extender instead of MOCA . Widely applied in MDI ' PUR series such as CPU /TPU /MPU . Can greatly improve polyurethane' temperature-resisting grade 、mechanical property such as tearing ength ,shearing ability, hardness& rigidity , elastic resilience. Effectively improve the storage stability & burning-resistance of PUR' gross rubber .
MDI/HQEE usually applied in the PUR products such as oil well seals , forklift tires ,conveyor belt ,hydraulic cylinder seals which have higher requirements on physical ability . Can improve the function of high resilient microspore foam products.

Package :
25kg/cardboard drum (with PE bag inside )
Storage:HQEE is easy to absorb humidity and can change color when under the sun . Should seal closely and keep from humidity and sunshine . Keep ventilation .
