HQEE's inventory calculation (for example)
Assuming that pre polymers- NCO content is 6.50%, crosslink coefficient f is 0.95, by the calculation, the 100 pre polymers should put in 14.85HQEE, the specific calculation as shown in the following type:
the hydroxyl equivalent inHER = =101
theamount of HQEE 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
HQEE is a solid aromatic diol chain extender with symmetrical molecular structure. It is recommended applied with MDI-prepolmer. HQEE/MDI system has long potlife than MOCA/TDI and MOCA/MDI systems, so workability is enhanced. HQEE-based polyurethane elastomer has higher tensile strength, tear strength, heat resistance, compression set, hardness and resilience than aliphatic diol chain-extended PUs.
HQEE can be used in casting polyurethane elastomer systems which the superior performance is required. The application includes oil well seals, forklift tires, seals for hydraulic cylinders, conveyor belt, etc. HQEE also used in high performance thermoplastic polyurethane elastomer, heat-resistant spandex and other production. It can also be used in milliable polyurethane elastomer.
PACKAGING
20 kg net weight in carton with polyethylene liner. (2 kg vacuumed packages inside each 20 kg carton.)
STORAGE
HQEE is sensitive to moisture and sunlight (UV), so keep it in airtight container and stored in a dry ventilated place, and keep away from light. Put desiccant inside the package . Make sure the remanent products well sealed after using.
