Resin sịntetik
Maleic anhydride na-emeghachi omume na polyols (site na njikọ cross-linking na styrene) iji mepụta unsaturated polyester resins (UPR), thermosetting resin. A na-ekewa UPR n'ime plastik fiber-reinforced (FRP, nke a na-akpọkarị fiberglass-reinforced plastik) na plastik na-anaghị akwalite.
A na-eji FRP arụ ọrụ n'iwu ụlọ (dịka ọmụmaatụ, mpempe akwụkwọ corrugated, ụlọ ndị e ji aka rụọ, ọdọ mmiri, ụlọ ịsa ahụ, tankị mmiri mkpofu), mmepụta ihe (dịka ọmụmaatụ, ihe ndị dị n'èzí ụgbọ mmiri/ụgbọala, ihe ndị e ji achọ mma n'ime ụlọ, bathtub, ọnụ ụzọ/windo, bọọdụ mkpuchi eletriki), injinịa kemịkalụ (dịka ọmụmaatụ, paịpụ, tankị nchekwa, ngwa gburugburu ebe obibi), na ngwa ahịa ndị ahịa (dịka ọmụmaatụ, mkpanaka ịkụ azụ, raketị, bọọdụ snow, klọb golf, okpu agha nchekwa).
A na-eji UPR nke na-anaghị akwalite ike eme ihe na simenti polyester, ihe ndị na-ejikọ ihe, ihe mkpuchi elu (piano, arịa ụlọ), bọtịnụ, na mabụl/onyx arụrụ arụ.
