Curv by Propex Fabrics GmbH is a material that combines the versatility and recyclability of a 100% thermoplastic with the high performance of a fibre reinforced composite.

In a patented process, where fibres are melted together, Curv captures the mechanical properties of woven polypropylene fibres in a self-reinforced polypropylene matrix. High stiffness, high tensile strength and high impact resistance provide the possibility to produce lightweight parts with outstanding properties in a totally recyclable thermoplastic. Advantages are:

– Weight saving: nearly 50% of weight is saved when comparing Curv to glass reinforced materials.
– Environmental friendly: being 100% propylene, Curv is easily recyclable, both as factory waste and as consumer parts.
– No irritation: because of the lack of glass fibres, Curv is skin friendly and easy to handle. Additional coating is not required
– Thermoformable: Curv’s thermoforming characteristics enable parts to be produced using low pressure, low cost tooling at modest temperatures.

Curv is applicable in for example the automotive industry, for sports equipment and for travel gear. The lowest picture shows a composite of foam with Curv outer layers.
