橡膠是提取橡膠樹、橡膠草等植物的膠乳，可制成有絕緣性、有彈性、不透水和不透氣的材料。新鮮的天然膠乳含橡膠組分27%～41．3%(質(zhì)量)、蛋白質(zhì)0．2%～4．5%、糖類0．36%～4．2%、水44%～70%、天然樹脂2%～5%、灰分0．4%。橡膠樹割膠流出，呈乳白色，固含量為30%～40%，橡膠粒徑平均為1．06μm，可直接作表面涂層、制造薄膜和膠粘劑等，經(jīng)加工也可制成生橡膠、膠乳制品(如手套、海綿、氣球、科研膠管等)，廣泛應(yīng)用于日常生活中。橡膠的廣泛應(yīng)用帶動(dòng)了當(dāng)?shù)亟?jīng)濟(jì)的快速發(fā)展，但是膠液的收集確是一大難題。目前，海南大部分膠農(nóng)還是采用人工割膠，勞動(dòng)強(qiáng)度大、效率低、安全性差，從而導(dǎo)致了綜合成本偏高，*地制約了橡膠產(chǎn)業(yè)化、商品化的發(fā)展
