環(huán)氧樹脂屬于熱塑性的線型樹脂，不能直接應(yīng)用，必須向其中添加固化劑組分，生成三維網(wǎng)絡(luò)結(jié)構(gòu)才能體現(xiàn)其獨(dú)特的性能。在固化劑產(chǎn)品中，酸酐類固化劑占有重要地位，是固化劑市場(chǎng)用量較大，應(yīng)用較為廣泛的品種之一。

拉擠制品中，環(huán)氧樹脂體系固化劑一般采用酸酐類固化劑。盡管也采用不飽和樹脂拉擠成型加工，但其綜合性能，尤其在機(jī)械性能、絕緣性能、收縮率方面，均不如環(huán)氧樹脂拉擠產(chǎn)品。
In the production of pultrusion products, the curing agent of epoxy resin system is generally anhydrides. Although it is also processed by pultrusion of unsaturated resin, its comprehensive properties, especially in mechanical properties, insulation properties and shrinkage, are not as good as epoxy pultrusion products.
