• Thermosetting polymer kple crosslink ƒe kpekpeme gã.

• Dzoxɔxɔ ƒe tsitretsitsi: Zãzã atraɖii vaseɖe 180°C (si me 250°C le).

• Sesẽ gã (Modulus: 2–4 GPA) kple didime ƒe liƒo.

• Atikewo ƒe tsitretsitsi ɖe acidwo, gɔmeɖoanyiwo, kple atike siwo wotsɔna tsia dzodzodzoetsitsi nu ŋu.

Viɖe siwo le eŋu:

• Enaa xɔtuɖoɖo ƒe ŋusẽdodo (dzia sesẽ ɖe edzi to 10–20 ƒuta A).

• Flame Retardant (UL94 V-0 ƒe dzeside Halogen ƒe kpeɖeŋutɔ manɔmee).

• Gazazã nyuie ne wotsɔe sɔ kple thermoplastics tɔxɛwo.

• Atike siwo woate ŋu atrɔ asi le (Acid-Catalyzed alo dzoxɔxɔ-si wotsɔ wɔa dɔe).

Dɔbiagbalẽviwo:

• Tayawo: Sidewall ƒe atikewo (edoa ŋusẽ be woatso tsitretsitsi ɖe nu ŋu, ASTM D624).

• Dɔwɔƒewo ƒe alidziblanu: conveyor belts na teƒe siwo dzoxɔxɔ deŋgɔ le (le kpɔɖeŋu me, siminti numiemiewo).

• Nusiwo wotsɔna ƒoa ʋuʋudedi: brek ƒe akpawo (woléa ʋuʋudedi ƒe xexlẽdzesi ɖe asi le 0.35–0.45 le 200°C te).

• Foundry: Core Sand Binders (ɖea gas ƒe tɔtrɔ dzi kpɔtɔna le casting me).
