ULx is a composite membrane surface component that fits well in our range of Stratis membrane surface materials. It is built up of random array, non-woven filaments that provides an increased abrasion resistance.
ULx 0.5 -RS Black is the lightest version of ULx. The other ULx 0.5 surfaces are fitting well in the Stratis membrane surface materials weight range between the UL 0.5 and the GPc 0.5 with around 10g/m² weight difference on either side. ULx 0.75 White has the same weight as the GPc 0.75 Taffeta White.
The ULx composite material creates a softer hand and minimizes creasing.
The ULx surface exhibits several characteristics that extend sail life. The non-woven construction closes the open windows of the base scrim, demonstrating considerably less shrinkage than film sails over time. The added stability of the non-woven filaments is a key factor in maintaining designed shape over the life of the sail.

The ULx surfaces are designed specifically for the high-performance sailor who is looking to get longer life expectancy out of their sails. The ULx surfaces provide superior abrasion resistance and offer better protection of the inner fibre construction of the membrane compared to film/film styles.
Compared to standard external taffeta membranes, water absorption is significantly less and dries much faster due to its ability to evaporate moisture.
ULx is exceptional in sun exposure, exhibiting outstanding UV resistance in lab tests and maintaining tensile strength of the underlying fabric.

Our ULx range currently consists of 4 varieties that have been in production and are fully tested:
ULx 0.5 RS Black, very stable and lightweight. Recommended for Grand Prix and racing, this product is expected to outperform all other UL products.
ULx 0.5 Charcoal, colour is charcoal, non-see through.
ULx 0.5 White, colour is opaque white, shows the internal fibre layout.
ULx 0.75 White, has the same look as the GPc 0.75 but will have all the advantages as described above.
