coconut Posted October 12, 2010 Share Posted October 12, 2010 I have 4630 paraffin container blend with a lower melt point than my J50 paraffin container blend. The 4630, while soft, is firmer than the J50 which is quite soft and sticky. Does anyone have any insight on that? TIA. Quote Link to comment Share on other sites More sharing options...
Brad Ford Posted October 13, 2010 Share Posted October 13, 2010 (edited) Melt point and softness have no direct relationship. It has more to do with the chosen raw materials for each blend. Edited October 13, 2010 by Brad Ford Quote Link to comment Share on other sites More sharing options...

I wondered what changed.... the melt point seems to be the same. Quote Link to comment Share on other sites More sharing options...
Brad Ford Posted October 14, 2010 Share Posted October 14, 2010 Generally, the more components you have in a blended product, the greater degree of variability you will have. Each of the individual raw materials has spec range for melt, softness, viscosity, etc. Sometimes you could get a batch in which all the ingredients were skewed to one end of the spec - which will give you some atypical properties. Yet still be within manufactures specifications. Melt point is typically the most consistent vs softness.Conversely, this is why straight paraffin is so reliable - it's just one component and very consistent.
