ULTRA 100 PSA with adhesive, with UHMWPE, small piece, storm grey

The ULTRA 100 PSA self-adhesive has a versatile and reliable adhesive layer on the film side of the base fabric. This makes it perfect as seam reinforcement on ULTRA fabrics or all EPLX ECOPAK®-Styles , e.g. on the shoulder strap attachments or for quick repairs on the go. However, ULTRA 100 PSA naturally adheres to a wide variety of smooth, clean surfaces, whether for quick repairs or when sewing is not possible. Suitable as a reinforcing tape for heavily used seams and bars, for individually cut reinforcements on tarp and sail corners, as a strong, waterproof seam tape or as a repair patch on tour.

The basic fabric is the same as the ULTRA 100 version that we already have in our range, so the same applies here:

With the ULTRA laminates, Challenge Sailcloth is launching a new high-performance backpack laminate. The ULTRA laminates have a 2-layer structure: On the outside is a fabric made of high-strength UHMWPE fibres and polyester. UHMWPE fibres are currently considered the non-plus-ultra in terms of tear strength and abrasion resistance and are also known as Dyneema®, Spectra® or Tsuunoga®. A matt, thin, waterproof polyester film is laminated to the inside. Due to the high proportion of 67% UHMWPE fibres, even the lightweight ULTRA versions achieve technical values in terms of abrasion resistance and tear strength that do not need to hide behind much stronger Cordura® fabrics. The polyester film ensures that ULTRA is reliably waterproof and has very good dimensional stability. The range of use is determined by the strength of the outer fabric and the associated abrasion and tear resistance.

When developing the ULTRA laminates, Challenge Sailcloth focused on sustainability in addition to performance:

- The PES film used is made of 100% recycled polyester from post-consumer PET bottles.

- Recycled polyester is used for the polyester content in the outer fabric, depending on market availability. If you value guaranteed 100% recycling, we recommend the ECOPAK® laminates by Challenge Sailcloth.

- Only FC-free C0 impregnations are used.

- No VOCs (Volatile Organic Compounds) are used in the production of ULTRA, and all adhesives are solvent-free.

- Thanks to an innovative production process, energy-intensive drying processes during lamination are reduced

The base fabric ULTRA 100 for the PSA-version uses a blend of 100den UHMWPE fibres and polyester for the outer fabric. Thanks to the very high proportion of 67% UHMWPE fibres, this achieves maximum abrasion resistance, tear strength and durability for the weight of 99g/sqm. This blend is combined with a matt, waterproof and UV-stable 0.5mil polyester film on the inside and an additional layer of adhesive. The result is the ultimate ultra-lightweight backpacking fabric reinforcement- at low weight, it has twice the tear strength and twice the abrasion resistance of 500den Cordura®!

The Challenge Sailcloth release paper on the back has a metric grid for easier cutting.

A small piece of ULTRA 100 PSA has the size of app. 0,5m x 0,5m.
