Polyester or Teflon Thread

Here at SLO Sail and Canvas there are two types of threads that we typically use on our trampolines and boat covers: V-138 UV stabilized polyester thread and Tenara Gore Tex 100% PTFE fiber (commonly known as Teflon). Thread is so important because it is nearly always the first thing to come apart in a boat cover or trampoline. I’ll give you the run down on both of these threads.

V-138 Polyester thread
This thread is the standard in sailmaking. It has extremely high tensile strength and abrasion resistance, and maintains very good mildew, saltwater, and UV resistance. This thread is larger than any household thread you’ll ever see, and it’ll take any beating that you’ll give it. The only drawback on this thread is its longevity due to prolonged sun exposure. High sun exposure, especially for those near to the tropics (Florida, Australia, etc..), can cause this thread to lose all of its strength after 3-5 years and cause you to have to get your trampoline restitched (usually in excess of $50).

Tenara Teflon thread
Nearly everyone will benefit from having Teflon thread used to hold together their products, but for those in high sun exposure areas it’s vital. Teflon is completely resistant to UV sunlight, rot, mildew, and color fading. It is also unaffected by cleaning chemicals (even bleach!), saltwater, and even acid rain. With this thread, a trampoline will virtually last forever and a boat cover will last as long as the fabric.

Our boat covers made from Sunbrella and Top Gun come standard with the Tenara thread, and our polyester covers come with the V-138 polyester thread. Our trampolines come standard with the V-138 polyester thread, with the option to upgrade to Tenara thread. If you like what you see, check out our store.
