needle penetration
Molecular formula :
MW :

nature : standard cone (usually a total load of 150 grams, has provided 100 grams) in five seconds later sank to 25 ° C insulation in the grease sample depth. Units 1 / 10 mm. The bigger the needle into the more soft Grease said that the smaller the consistency; Instead, said the more hard Grease, the greater consistency. Asphalt penetration test, not the standard cone and used a total of 100 grams of truck standards Jianzhen. Determination of Grease with the same conditions.
