環(huán)氧板具有以下特點(diǎn)：1、形式多樣。各種樹脂、固化劑、改性劑體系幾乎可以適應(yīng)各種應(yīng)用對形式提出的要求，其范圍可以從極低的粘度到高熔點(diǎn)固體。2、固化方便。選用各種不同的固化劑，環(huán)氧樹脂體系幾乎可以在0～180℃溫度范圍內(nèi)固化。3、粘附力強(qiáng)。環(huán)氧樹脂分子鏈中固有的極性羥基和醚鍵的存在，使其對各種物質(zhì)具有很高的粘附力。環(huán)氧樹脂固化時的收縮性低，上海fr4環(huán)氧板廠家哪家好，產(chǎn)生的內(nèi)應(yīng)力小，這也有助于提高粘附強(qiáng)度。4、收縮性低。環(huán)氧樹脂和所用的固化劑的反應(yīng)是通過直接加成反應(yīng)或樹脂分子中環(huán)氧基的開環(huán)聚合反應(yīng)來進(jìn)行的，沒有水或其它揮發(fā)性副產(chǎn)物放出。它們和不飽和聚酯樹脂、酚醛樹脂相比，在固化過程中顯示出很低的收縮性（小于2%）。5、力學(xué)性能，上海fr4環(huán)氧板廠家哪家好。固化后的環(huán)氧樹脂體系具有優(yōu)良的力學(xué)性能，上海fr4環(huán)氧板廠家哪家好。上海偉奮實(shí)業(yè)有限公司為您提供環(huán)氧板，期待為您服務(wù)！上海fr4環(huán)氧板廠家哪家好</p><div

形式多樣 </p> <p> 各種樹脂、固化劑、改性劑體系幾乎可以適應(yīng)各種應(yīng)用對形式提出的要求，其范圍可以從極低的粘度到高熔點(diǎn)固體。 </p> <p> 固化方便 </p> <p> 選用各種不同的固化劑，環(huán)氧樹脂體系幾乎可以在0～180℃溫度范圍內(nèi)固化。 </p> <p> 粘附力強(qiáng) </p> <p> 環(huán)氧樹脂分子鏈中固有的極性羥基和醚鍵的存在，使其對各種物質(zhì)具有很高的粘附力。環(huán)氧樹脂固化時的收縮性低，產(chǎn)生的內(nèi)應(yīng)力小，這也有助于提高粘附強(qiáng)度。 </p> <p> <p> 收縮性低 </p> <p> 環(huán)氧樹脂和所用的固化劑的反應(yīng)是通過直接加成反應(yīng)或樹脂分子中環(huán)氧基的開環(huán)聚合反應(yīng)來進(jìn)行的，沒有水或其它揮發(fā)性副產(chǎn)物放出。它們和不飽和聚酯樹脂、酚醛樹脂相比，在固化過程中顯示出很低的收縮性（小于2%）。 </p>
