PA6.6 – Polyamide 6.6 PA66-I
AKROMID® A3 3 S1 black (21004)
AKROMID® A3 3 S1 black (21004) is an unreinforced, nucleated, highly cold impact modified polyamide 6.6
Connectors and fixtures for the automotive electro and furniture industry, if high impact resistance at low temperatures is required.
The listed values are recommendations. Higher values should be used for higher glass loadings. We recommend only de-humidifying or vacuum dryers. Extensive drying can cause filling problems and surface defects.
