ASTALAC ASA™ 314ASTALAC™ ASA 314 is a high melt flow, high impact grade of ASA which is designed for applications requiring a combination of toughness, mouldability, rigidity and heat resistance. ASA grades show superior colour and property retention compared to ABS and are typically used in applications such as exterior components requiring improved weatherability. Note: The letters “UV” or “W” indicate additional UV stabilisation [ ie: ASTALAC™ ASA 314UV ].
