Main Application:
HER is aromatic diol chain extender.It has good compatibility with MDI.Widely applied in PU elastomer of millable、casting and thermoplastic.It is certified that HER could maintain elatomer’s persistence、elasticity and plasticity.At the same time,it can minimize the limitation of contractibility property and no pollution.Besides the advantages of aromatic chain extender,HER hasn’t the disadvantages of HQEE’s crystallization rapidly with cool slightly and could provides better plasticity、tearing strength、initial strength、shore hardness、compression deformation and special advantages like low shrinkage、the shear resistance、good toughness、non-permeable、low melting point、easy operation.As the chain extender,it is available to cast wheel、sealing element、inviscid combination of tyres、the mud pipe lining、the skateboard wheels、beverage container、flexible and stiff package material.
Package: 25kg/cardboard drum(with PE bag inside)
Storage: HER is easy to absorb humidity and can change color under the sun.Should seal closely and keep from humidity and sunshine.Keep ventilation.
Expiration Date: one year.
