Polyester is a chemical fibre and a microfibre, which consists of polyethylene terephthalate, or PET for short. The basic raw materials are coal, limestone, crude oil, and natural gas. Polyester is used in many of our straps which are required to permanently and reliably absorb large forces and recurring loads.


  • very durable
  • high tear resistance
  • pull loops
  • crease-resistant
  • good abrasion resistance
  • very high weather resistance
  • high UV stability
  • can be used in temperature ranges from -30°C to 80°C
  • good resistance to most diluted acids

  • Roller shutter straps / elevator belts
  • Edge binding


Even though, from a chemical perspective, polypropylene is relatively similar to PE, it has significantly harder and firmer properties with greater thermal resistance. The maximum continuous operating temperature is approx. 100°C. Special compounds allow for both higher as well as lower operating temperatures. These properties make polypropylene a particularly popular product in strap weaving.


  • large selection of colours in spinneret-dyed yarn
  • gentle to the skin
  • lightest commercial fibre
  • very low water absorption, fast drying
  • high resistance to seawater
  • good resistance to alkalis and non-oxidising acids
  • buoyant
  • 100% recyclable

Example applications

  • Medical products and sports textiles
  • Roller blind straps / elevator belts (mixed-fabric with polyester)
  • Carrying straps / lifting straps / carrying loops
  • Nail strips

Dyneema ®

Dyneema is a synthetic chemical fibre based on polyethylene with an ultra-high molecular mass. The fibres have the lowest density of all reinforcement fibres and the highest specific strength (ration of strength to weight). With its high load-bearing capacity, Dyneema straps can be thinner than polyamide webbing loops and still have the same load-bearing capacity.


  • very high tensile strength, highest specific strength
  • very minor elongation at high loads
  • low weight
  • very good abrasion resistance
  • low friction factor / good sliding properties
  • high cutting resistance
  • excellent cold resistance
  • high UV stability
  • good weather resistance
  • buoyant
  • very good resistance to alkalis, acids, oils, and fuels
  • water absorption <1%
  • low shrinkage
  • temperature resistant up to 130°C


Polyamides are processed into fibres at massive quantities, and also rank amongst the most important technical thermoplastics. These tough materials have a high strength and stiffness, excellent impact resistance, as well as good abrasion and wear resistance. Brand names include Nylona (PA 6.6) and Perlon (PA6).


  • very high tensile strength and abrasion resistance
  • crease-resistant
  • dimensionally stable
  • high elongation
  • very soft and pleasant grip
  • good sliding properties
  • very good resistance stability from -40°C to 90°C
  • very good skin tolerability

Example applications

  • Textile straps for energy absorbers
  • Animal leashes / dog leashes / lungeing leashes
  • Belts
  • Binding tape


Aramid fibres have a high specific (weight-related) strength, low density, high impact resistance, good heat resistance and dimensional stability, good vibration dampening, and a high energy absorption capacity. The strength perpendicular to the longitudinal axis of the fibre is relatively low. As such, the diagonal strength and the compressive strength of synthetic aramid fibres is significantly lower than those of GFK and CFK (e.g. interlaminar shear strength is approx. 50% of the material strength).


  • very high tensile strength and specific strength
  • extremely low elongation at high loads
  • low shrinkage
  • very good cutting protection
  • good permanent heat resistance at continuous loads, up to 350°C
  • no melting and dripping when exposed to heat
  • self-extinguishes after removing the ignition source
  • high resistance to chemicals, except strong acids and bases
  • resistant to most solvents
  • seawater-resistant
  • dimensionally stable

Example applications

  • as a tensile member in applications demanding very low elongation under high tensile strain
  • vandalism protection (cutting protection)
  • shock absorbers, for example in bulletproof vests
  • tension relief
  • fibre composites


Basalt fibres are thin fibres made from basalt. Basalt fibres are created from liquid molten basalt at temperatures of approx. 1400(+/-50)°C. The composition of the molten liquid influences the physical properties of the basalt fibres. Contrary to carbon or aramid fibres, basalt fibres aren’t stretched but rather amorphous, similar to glass fibres. The high strength of basalt fibres compared to compact basalt is as such merely a result of the size-effect. Basalt is a highly valuable raw material for the production of textile belt straps.


  • very high heat resistance
  • non-flammable
  • insensitive to UV light and other atmospheric influences
  • very good resistance to strong acids and alkalis
  • not electrically conductive
  • less expensive than carbon
  • higher tensile strength than steel

Example applications

  • to substitute metal/steel cables
  • fire protection
