1 mm – Inner Sleeve
The flexible and expandable inner sleeve contains Dyneema® which offers maximum strength combined with minimum weight. It is up to 40% stronger than aramid fibres such as Kevlar®. Dyneema® fibre is extremely durable and resistant to moisture, UV light and chemicals.

2) 1 mm –  Foam Layer
The compressible pre-compressed foam layer has high rebound resilience and is up to 50% compressible without bulging. It is resistant to permanent deformation, good abrasion resistance and resistance to ageing, weathering and cleaning solvents.

3) Core Material 
Stitch, bonded and compressed core material contains a filament fibre base which is volumized by thermoplastic micro balloons which is light weighted and has extreme high flexural strength and form stability.

4) 2 mm – Outer Surface Layer
Contains Epoxy Vinyl-Ester-Resin reinforced with technical filaments and polyester fleece. High chemical and temperature resistance with excellent tape mount and demount properties.

5) Compressible Surface Layer (Tech Sleeve® Soft & Tech Bridge® Soft)
The compressible surface layer (40, 50 or 60 ShA) consists of cellular, water crossed-linked foamed polyurethane.
