The supply of raw materials has also approached self-sufficiency. At present, 37 large scale factories produce such raw materials as PVC, PE, PS, PVAC, PMMA, Acid Formaldehyde Resin, UF and Unsaturated Polyacetic Acid Resin. The output is abundant and the quality reaches international standards.
原料供應方面，也力求自行生產，到目前為止，台灣生產的原料有聚氯乙烯、聚乙烯、聚苯乙烯、聚醋酸乙烯、聚甲基丙烯酸甲脂、酸甲醛樹脂、尿素甲醛樹脂、不飽和聚醋樹脂等等，工廠有三十七家，均具備有相當的規模，產量相當豐富，品質也均合乎國際水準。
