--- Quote from: forrestc on July 02, 2019, 06:31:03 am ---I've bought several of these packs over the years. Generally they all work. I'm not sure I've ever had heat shrink which didn't shrink, even from potentially dodgy sellers. Some are of course better than others. I've recently just switched to the adhesive lined type for pretty much everything. But again, by the time I'm heat shrinking it, I don't want it to ever come off. This may or may not be a good thing for you. --- End quote --- I have a stock of the evilBay stuff and it works to my satisfaction. Then again, my level of satisfaction may be low compared to others. I do like the adhesive but I have so much that at my age, it may be a lifetime supply. If I ever need to buy again, I would probably go for the adhesive. |

I’ve run into the “almost rigid” issue when using heat shrink for strain relief. --- End quote --- Sorry. I buy this stuff when I see a good deal -. at local stores, swap meets, on-line etc It then goes into a bin. It may be years before a particular bit is used and I have no idea by then of the source. It is often unmarked, or has a resellers label. Some of the differences I note may be simple aging of the material. Shelf life on heat shrink is not a subject I have explored. |

--- Quote from: blueskull on July 01, 2019, 10:46:25 pm ---If it says polyolefin and says 3:1 shrinking ratio, then it's good. I fail to see 3M being any better, even I use a mix of them. --- End quote --- I always look for polyolefin. It does not become sticky, can be molded it while hot, and is incredibly tough. |
