Kyakkyawan Performance ASA-GF, FR don samfuran ƙofar waje

Acrylonitrile styrene acrylate (ASA), wanda kuma ake kira acrylic styrene acrylonitrile, wani amorphous thermoplastic da aka samar a matsayin madadin acrylonitrile butadiene styrene (ABS), amma tare da ingantacciyar juriya, kuma ana amfani dashi sosai a cikin masana'antar kera motoci. Yana da acrylate roba-gyara styrene acrylonitrile copolymer. Ana amfani da shi don samfuri na gabaɗaya a cikin bugu na 3D, inda juriyarsa ta UV da kaddarorin injiniya suka sa ya zama kyakkyawan abu don amfani a cikin firintocin ƙirar ƙira.

Tsarin ASA yayi kama da ABS sosai. Barbashi mai siffar zobe na dan kadan giciye acrylate roba (maimakon butadiene rubber), masu aiki azaman mai gyara tasiri, ana dasa su ta hanyar sinadarai tare da sarƙoƙi na styrene-acrylonitrile copolymer, kuma an saka su cikin matrix na styrene-acrylonitrile. Rubber acrylate ya bambanta da roba tushen butadiene ta rashi biyu shaidu, wanda ke ba da kayan kusan sau goma juriya na yanayi da juriya ga hasken ultraviolet na ABS, mafi girman juriya na zafi na dogon lokaci, da mafi kyawun juriya na sinadarai. ASA yana da matukar juriya ga fatattakar danniya na muhalli fiye da ABS, musamman ga barasa da ma'aikatan tsaftacewa da yawa. N-Butyl acrylate roba yawanci ana amfani da shi, amma sauran esters kuma ana iya saduwa da su, misali ethyl hexyl acrylate. ASA yana da ƙananan zafin canjin gilashin fiye da ABS, 100 °C vs 105 °C, yana ba da mafi kyawun ƙarancin zafin jiki ga kayan.
