    XYlink HQEE-L is para-substitution phenylether glycol mixture with 4-hydroxyethoxy-1-hydroxyethyl benzendiether as the main component. It is a homologue of the chain extender HQEE and could be considered as a liquid version of HQEE. HQEE-L has good operability than HQEE. It is suggested to be warmed 35-40℃ to get easy operability when it is frozen in winter. This product is applicable to medium hardness of elastomeric polyurethane products. The PU elastomers based on XYlink HQEE-L has good properties such as better elongation and flexure. The PU elastomers has good mechanical property and heat resistance than those based on aliphatic diol such as 1,4-butanediol.
    XYlink HQEE-L is suitable for both TDI and MDI polyurethane systems. It can be widely used in polyurethane elastomer (casting, thermoplastic and millable type), sealing materials, polyurethane adhesives, coatings, foams, Spandex, pavement materials and other fields.

    20kg net weight in plastic drum.

    XYlink HQEE-L should be stored in a ventilated and dry place .Keep the container well sealed after using and fill neutral gas (such as nitrogen) to prevent moisture.
    The quality guarantee period is 24 months. Even though the product exceeds the expiration date, it could also be used if it is qualified by testing.
