Main Application :

HQEE is a new-style poisonless chain extender instead of MOCA. Widely applied in MDI’s PUR series such as CPU / TPU / MPU. Can greatly improve polyurethane’s temperature-resisting grade , mechanical property such as tearing strength 、shearing ability 、hardness and rigidity 、elastic resilience. Effectively improve the MPU’s size material’s storage stability and burning-resistance. And improve PUR’s property.

MDI/HQEE usually applied in the PUR products such as oil well seals , forklift tires , conveyor belt , hydraulic cylinder seals which have higher requirement on physical ability. It can improve the function of high resilient micropore foam products.

Package : 25kg/cardboard drum (with PE bag inside)

Storage : HQEE is easy to absorb humidity and can change color under the sun. Should seal closely and keep from humidity and sunshine. Keep ventilation.
