ASA INEOS Styrolution S777K

ASA INEOS Styrolution S777K is an acrylonitrile‑styrene‑acrylate copolymer with outstanding UV‑resistance, good flowability and processing properties. It is an ideal choice for applications requiring stringent weather‑resistance requirements, such as automotive exterior parts and outdoor building materials.

Main Applications

Automotive components: automotive front grilles, exterior rear‑view mirror housings, etc.

Outdoor building materials: extruded products such as roof edges, window frames and roof tiles.

Others: also used for weather‑resistant products including satellite antennas, garden facilities and outdoor lamp housings.
