ASA是一種由丙烯腈（acrylonitrile）、苯乙烯（Styrene）、丙烯酸橡膠（Acrylate）組成的三元聚合物， 屬于抗沖改性樹脂，ASA具有良好的機械物理性能，比較好的耐高溫性能，廣泛應用于軌道交通、汽車領域、建筑領域、園藝領域、電子電氣領域，ASA改性塑料用于戶外墻板需要符合澳標AS3959 BAL29防火等級要求。南京睿督公司與澳洲NATA資質實驗室合作，提供澳標AS3959 Bushfire Attack Level－BAL防火等級測試 BAL29/BAL40防火等級測試，具體內容請咨詢南京睿督公司，咨詢電話：025-8658 3475。

AS/NZS 3959-2009 Construction of buildings in bushfire-prone areas （Bushfire Attack Level－BAL防火測試）

In the Australian Standards AS 3959, they have classified different bushfire intensity levels that a home may experience during a bushfire. These are referred to as Bushfire Attack Levels, or BAL’s for short.

There are 6 bushfire attack levels in total, these are;
BAL Flame Zone
BAL 40
BAL 29
BAL 19
BAL 12.5
BAL Low
These individual levels are based on;

AS/NZS 3959 BAL防火測試對象
Subfloor supports, Floors, External wall, External door, roofs, Verandas decks, etc,

AS/NZS 3959澳標適用范圍
This Standard specifies requirements for the construction of buildings in bushfire-prone
areas in order to improve their resistance to bushfire attack from burning embers, radiant
heat, flame contact and combinations of the three attack forms.

Although this Standard is designed to improve the performance of buildings when subjected to bushfire attack in designated bushfire-prone areas there can be no guarantee that a building will survive a bushfire event on every occasion. This is substantially due to the unpredictable nature and behaviour of fire and extreme weather conditions.

ASA工程塑料與ASA改性塑料的區別

ASA工程塑料和ABS改性塑料都是大家熟習的通用工程塑料，它們都是橡膠增韌的苯乙烯—丙烯腈共聚物(SAN)。ABS改性塑料是用聚丁二烯橡膠或丁苯橡膠增韌的共聚物,而ASA工程塑料是用丙烯酸酯橡膠增韌的SAN。

ABS改性塑料由于其分子鏈中的丁二烯組分含有雙鍵，容易氧化降解和光降解，在經過較短時間的光照后顏色就會發黃，所以ABS改性塑料不適合用于室外。ASA工程塑料的分子鏈上沒有雙鍵，耐候性要好得多。

ABS改性塑料的耐候性很差，而ASA工程塑料和UPVC的耐候性都很好。但由于丙烯酸酯類聚合物的價錢很高，ASA工程塑料的價錢就要比ABS改性塑料貴得多。
