Quick question; Does anyone out there know the breaking strength of seaguar 100lb thread lock...Paul
ifish42na ,,,,is right on 👍
The information you seek is contained in the link below.

Hope this helps,

    Interesting… JB does not make the spectra or weave the braid. Also the testing can vary from each tester or machine. The diameter is different. Still valuable info at least for me.

    Great question 👍
    The basic answer is given by af dreamer above. Valuable information that most are not aware of.

    To be more specific it boils down to manufacturing inconsistencies in the extrusion process. It is very difficult to keep material formula ratios and extrusion diameter of lines, be it plastic or spectra, to the exacting standards required for consistent product testing results. What is being witnessed here is a prime example of that issue. That is why such extreme over test is observed in lines of a given pound test. They need that over test to compensate for the low end of the of the breaking points. But this is not always successful as witnessed buy reports on BD of guys having 60lb breaking at 20 lbs. Am willing to speculate that most of us have at one time have had line break at very low stress for some unknown reason. The data below shows a prime example of production inconsistencies. The 117.80 and the 105.40 are fairly consistent, the wt. per ft. and the diameters are comparable. The aprox. 11% difference in Actual lb Test is close enough. But the 89.25 Break strength is a disaster, the Wt. per ft. is greater and the diameter is larger which would indicate a higher Actual lb test not lower lb test. But the line still meets the labeled 80 lb test requirements.
    Over test to the rescue. With the current trend for mfgs. of reducing line diameters for the same lb. test ,,,can only think that the frequency of this issue will only increase.

    Who compiled the information in the chart? To whoever did it, Thank you! It is valuable information and a good starting point.

    However, the main thing I learned when Paulus was doing his testing was that braid manufacturers are not consistent. Diameters, weaves, and breaking strength change significantly. In an industry without standards, it is difficult to trust numbers from batch to batch.

    Last fall I got 5 samples of Izor 65 solid from 2 long range boats and 3 tackle shops and compared them to my bulk spool from a few years ago. I found 3 different weaves and diameters. I have used bulk Izor for more than a decade but that was disconcerting.

    I have gotten into the habit of testing braid before I buy it, and when I buy, I get the biggest spool. The most important thing to me is knowing what my line will do and avoiding big surprises.

    After being surprised in the past by Tuffline, JB, and the Izor from last year I sampled Power Pro and found it better than I remembered. I bought bulk spools that will last me for a very long time. I purchased 50, 65, and 80 and tested all of them. All had very consistent breaking strengths of +/- 10% over the stated line rating. It is thin compared to other braids in the same line classes and has the texture that I like for tying FG knots.

    I’m partial to PowerPro hollow even though I don’t use it as what it was maid to do.I just tie top shot to it with the RP.I like the way it lays and feels better than conventional braid.JMHO,Tom
