Material, construction

Thermoplastic polyurethane (TPU) is highly resistant to, for example, petroleum products and is easy to remove lubricants or other contaminants. The seams of this suit are joined and sealed by high-frequency welding and feature the same strength as the material itself. The high durability of the material is complemented by ergonomic features that ensure comfort in use. Instead of the classic neoprene harness, the suit can also be supplied with a neckpiece for diving helmet use and steel reinforced PU work boots are available instead of neoprene boots. A back zipper with cover flap also ensures the suit's long-term durability, and integrated braces ensure comfort during use. As a special accessory for rescue workers and rescue divers, the suit can be supplemented with an integrated buoyancy vest. Another useful accessory is the integrated internal handles for quick donning of the suit in confined spaces - e.g. fire trucks.

Why is the Pursuit X3 suitable as a working suit for a professional diver?
  • The material is flexible like most rubber materials
  • Pursuit Prof1Highly abrasion and puncture resistant
  • Highly UV and oil resistant
  • Long life, thanks to the fully synthetic material it does not age
  • High-frequency welded seams, very strong, no stitches, no adhesive tape
  • Fast-drying, water-repellent surface
  • Easy to clean, e.g. from oil or dirty water
  • Easy to repair
  • Weighs half as much as a rubber suit
Mechanical properties

TPU has excellent physical properties. Extreme tensile and tear resistance as well as elasticity result in this suit being very suitable as a work suit. The wear resistance of TPU is excellent. Many shoe manufacturers use TPU for the production of soles. And did you know that the wheels on roller skates are also made of TPU? Temperature range

The temperature range of applicability of TPU is very wide. As a suit material it softens at +70°C, for short-term heating at +120°C. It is also resistant to low temperatures down to -45°C.

Hydrolysis tolerance

TPU has been tested by immersion in water for several years and no effect or weakening effect on the mechanical properties of the material has been observed.

Resistance to oil and solvent and microorganisms

TPU is chemically resistant to (non-polar) solvents such as hexane or heptanes. Mineral oils such as diesel oils and lubricants will not harm this material. Some synthetic oils can damage TPU. Toulene and acetone soften the TPU surface. Tetrahydrophran, methyl ethyl ketone and dimethylformamide can partially or fully destroy TPU. TPU is very durable against microorganisms, only the colour of the material may change. Mechanical properties are not compromised.
