I've been using Nelco Products for various tyrap and heat shrink tubing requirements for the past year and have found them -- and especially Bill -- to be very helpful, knowledgeable and responsive when I have a special requirement or urgent delivery need. I'm so glad I cam upon Nelco Products through an online search after a long-time supplier had yet again raised prices and was VERY unresponsive to special requests. Way to go Nelco!!
Nelco now offers a 4:1 shrink ratio for our most popular type of polyolefin shrink tubing. The flexible, flame-retardant tubing is specially overexpanded with minimal longitudinal change (5% max.).
