UL 3644

UL 3644 wire manufactured by Rowe Industries by using a single extrusion of silicone, which translates into less manufacturing processes and meaning lower prices. It's also lightweight and formed from base silicone rubber without the fiberglass braid found on most silicone wire products. Without the braid, there are no fraying issues, a reduced number of splices making it easier to process and strip, especially in high volume situations.  The braidless UL3644 wire also features better tensile strength as well as better abrasion and cut resistance, compared to other similar products on the market, most notably Radix's Sil-A-Blend.  See the difference in this video below.
