Product range

Three ranges, infinite possibilities.

Each range is optimised for a specific class of application. All compounds are customisable in colour, hardness and additive characteristics.

Range 01
Flexible PVC
60 – 80 Shore A

Highly plasticised compound for cable jackets, flexible pipes, technical articles and sealing profiles. Softness, resilience and resistance to chemicals.

Power cables Flexible hoses Seals
Range 02
Semi-flexible PVC
80 – 95 Shore A

The right balance between flexibility and dimensional rigidity. Ideal for cable trays, corrugated pipes, technical profiles and articles requiring elastic memory.

Cable trays Corrugated pipes Technical profiles
Range 03
Rigid PVC
50 – 60 Shore D

Compound with no or low plasticiser content for window profiles, structural pipes, sheets and components requiring high dimensional stability.
