ABS樹脂 化学特性,用途語,生産方法
解説
ABS樹脂,アクリロニトリル，ブタジエン，スチレンを重合させてつくられる樹脂で，それぞれのモノマーの頭文字をとってABS樹脂と呼ばれる。ポリスチレンの耐衝撃性を改善するために開発された樹脂であり，当初，アクリロニトリルとスチレンの共重合樹脂(AS樹脂)にアクリロニトリル･ブタジエンゴム(NBR)をブレンドしてつくられたが，最近では，NBRにアクリロニトリル，スチレンをグラフト重合したABS樹脂とか，そのグラフト樹脂とAS樹脂とのブレンド樹脂も製造されている。

調製方法
acrylonitrile-butadiene-styrene resins are commonly referred to as ABS resins. These materials are thermoplastic resins that are produced by grafting styrene and acrylonitrile onto a diene-rubber backbone. The usually preferred substrate is polybutadiene because of its low glasstransition temperature (just above ?80 °C). Where ABS resin is prepared by suspension or mass polymerization methods, stereospecific diene rubber made by solution polymerization is the preferred diene. Otherwise the diene used normally is a high-gel or cross-linked latex made by a “hot-emulsion” process.

? ABS is made in the USA using 100% virgin resin and colorants - precision extruded onto 1kg reels (2.2 lbs.). The filament is then vacuum-sealed with desiccant to protect it from moisture.
Advantages
ABS Resins is a strong and durable polymer. It is a chemically resistant resin. It gets easily attacked by polar solvents. It offers greater impact properties and slightly higher heat distortion temperature than HIPS.
It has a low melting temperature making it suitable for processing by 3D printing on an FDM machine.
ABS shows excellent mechanical properties. It is hard and tough in nature and thus delivers good impact strength. It offers a high degree of surface quality. Apart from these characteristics, Acrylonitrile Butadiene Styrene exhibits good electrical insulating properties.
It is an ideal material of choice for various structural applications. This is because of its several physical properties such as:
High rigidity, good weldability, and insulating properties; Good impact resistance, even at low temperatures; Good abrasion and strain resistance; High dimensional stability (Mechanically strong and stable over time); High surface brightness and excellent surface aspect
