古(gu)(gu)馬(ma)隆(long)(long)樹(shu)(shu)脂(zhi)(zhi)以(yi)乙烯焦油、碳九為原料經催化(hua)聚(ju)合反應而(er)得，產品外觀為黃色(se)、褐色(se)、黑色(se)塊狀固體(ti)，具(ju)有良好的相溶性(xing)(xing)、耐水性(xing)(xing)、耐酸堿性(xing)(xing)、防(fang)銹(xiu)和電(dian)氣特(te)性(xing)(xing)。 　　用(yong)(yong)途：古(gu)(gu)馬(ma)隆(long)(long)樹(shu)(shu)脂(zhi)(zhi)廣泛應用(yong)(yong)于橡(xiang)(xiang)(xiang)膠(jiao)(jiao)(jiao)、輪胎、三(san)角帶、輸(shu)送(song)帶、油漆、油墨(mo)、防(fang)水、膠(jiao)(jiao)(jiao)管等行業，無論是古(gu)(gu)馬(ma)隆(long)(long)樹(shu)(shu)脂(zhi)(zhi)，液體(ti)古(gu)(gu)馬(ma)隆(long)(long)或(huo)者橡(xiang)(xiang)(xiang)膠(jiao)(jiao)(jiao)單獨使用(yong)(yong)都無粘(zhan)(zhan)結性(xing)(xing)，復配后可使橡(xiang)(xiang)(xiang)膠(jiao)(jiao)(jiao)具(ju)有良好的粘(zhan)(zhan)結性(xing)(xing)，包括壓敏性(xing)(xing)或(huo)熱熔(rong)性(xing)(xing)，過去(qu)粘(zhan)(zhan)結劑(ji)多用(yong)(yong)于天(tian)然松香樹(shu)(shu)脂(zhi)(zhi)或(huo)茚烯樹(shu)(shu)脂(zhi)(zhi)，價(jia)格高，來源不穩定(ding)，性(xing)(xing)能也比(bi)不上古(gu)(gu)馬(ma)隆(long)(long)樹(shu)(shu)脂(zhi)(zhi)，同時在價(jia)格上古(gu)(gu)馬(ma)隆(long)(long)樹(shu)(shu)脂(zhi)(zhi)要比(bi)松香低，而(er)古(gu)(gu)馬(ma)隆(long)(long)樹(shu)(shu)脂(zhi)(zhi)產量要比(bi)松香產量穩定(ding)，目(mu)前在橡(xiang)(xiang)(xiang)膠(jiao)(jiao)(jiao)等行業古(gu)(gu)馬(ma)隆(long)(long)樹(shu)(shu)脂(zhi)(zhi)已(yi)占據粘(zhan)(zhan)結劑(ji)的主導地位。古(gu)(gu)馬(ma)隆(long)(long)樹(shu)(shu)脂(zhi)(zhi)加入橡(xiang)(xiang)(xiang)膠(jiao)(jiao)(jiao)中，可起到軟化(hua)、補強、增粘(zhan)(zhan)、分散等作用(yong)(yong)，從而(er)改(gai)進了橡(xiang)(xiang)(xiang)膠(jiao)(jiao)(jiao)的加工性(xing)(xing)能。

古馬隆(long)樹(shu)脂是采(cai)用乙烯工業副(fu)產的烯烴為原(yuan)料，通過聚合、蒸餾得到的淺(qian)黃色(se)至黑(hei)色(se)固(gu)體樹(shu)脂。古馬隆(long)樹(shu)脂具有熱塑性、增粘(zhan)增強性（軟化劑）。作為膠粘(zhan)劑樹(shu)脂、增粘(zhan)劑、軟化劑、廣泛(fan)應(ying)用于印刷業、橡膠制品、涂料等(deng)行(xing)業。
