Can provide some basic information of this product such as density, solubility, molecular weight
1 answer-
The average molecular weight is 300,000 MU and the bulk density is 350 kg/m3. HEC dissolves readily in water and is chemically and physically stable over a wide pH range. The viscocity of this product is not measured, however a similar product (308633) has a specification of 300 - 400 cps at 25 deg. C in water at 2%. Please check the literature for gelation conditions and properties. There are several HEC products available. See the link below to review:
