Product Name	Class	Appearance	Initial M. P, ℃≥	Loss on drying, ≤	Ash, %≤	Methanol insoluble substance %, ≤
NOBS	Superior Class	Light yellow or orange yellow granular	81.0	0.40	0.20	0.50
	First Class		80.0	0.50	0.30	0.50
	Qualified Class		78.0	0.50	0.40	0.80

8.Properties: The industrial products are light yellow or orange yellow granular, the specific gravity is1.34~1.40, melting point is 80.0~90.0℃( For industrial products, it is above 78.0℃). Easily soluble in dichloromethane, acetone, soluble in benzene, carbon tetrachloride, acetic ether, slightly soluble in gasoline, insoluble in water. The good storage stability period is half year. If exceed half year, it may speed up the sizing scorch tendency. It will dismiss gradually when meet with heat, so it should be stored under low temperature.
