Inventory calculation (for example)
Assumingthat pre polymers - NCO content is 6.50%, crosslink coefficient f is 0.95, by the calculation, the 100 prepolymers should put in 14.85 ehrs, specific calculation as shown in thefollowing type:
thehydroxyl equivalent in HER = =101
theamount of HER join to 100 pre polymers
= =14.85
(note:in this type, KOH with a molecular weight of 56.1; the hydroxyl value of HER is555; the isocyano-content of polymers is 6.50; the crosslink coefficient is0.95; the molecular weight of isocyano is 42
FEATURES & APPLICATIONS
HER is an aromatic diol chain extender with symmetrical molecular structure. Its structure regularity is less than its isomer HQEE because of two hydroxyethyl groups located on the benzene ring of 1,3-site (meta-). The melting point of HER is lower than HQEE, and the crystallization speed is slower than MOCA, can overcome the shortcoming of HQEE’s rapid crystallization. The workability is improved.
HER is recommended applied with MDI-prepolmer to produce casting, thermoplatic and milliable polyurethane elastomer products. HER-based polyurethane elastomer has good properties such as strength, tear strength, heat resistance, compression set, hardness and resilience than aliphatic diol chain-extended PUs.
HER chain-extended polyurethane elastomer can be widely used in various applications include rolls, wheels, seals, wear-resisting linings, skateboard wheels, shoe components, Spandex, etc. HER can also be used in polyester synthesis, polyurethane adhesives, coatings, etc.
PACKAGING
20 kg net weight in carton with polyethylene liner. (2 kg vacuumed packages inside each 20 kg carton.)
STORAGE
XYlink HER is sensitive to moisture, so it should be kept in tightly closed container and stored in a dry ventilated place. Put desiccant inside the package. Make sure the remanent products well sealed after using. Keep it away from sunlight, otherwise it would turn yellow.
