This datasheet of Technyl® A 402 Natural FA from Rhodia Polyamide Engineering Plastics is provided by the international plastics database CAMPUS.
CAMPUS is organized by a group of leading international resin producers, who have agreed to test their material according to uniform conditions, based on ISO standards (ISO 10350, ISO 11403), in order to offer comparable data to the market.
TECHNYL® A 402 NATURAL FA offers three main advantages: high impact resistance at low humidity levels, good rigidity, and excellent compression resistance.
This grade is particularly suitable for the moulding of plastic insulators for railway binding and for extrusion of plates and profiles.
Suitable for food contact applications (films, packaging, …).
This product is available in natural.
