手(shou)輪(lun)系列的(de)彈(dan)性其生膠(jiao)及交聯密度不太(tai)高(gao)(gao)的(de)liu化(hua)膠(jiao)的(de)彈(dan)性是高(gao)(gao)的(de)。例(li)如(ru)在(zai)0-100℃范圍內，回彈(dan)性在(zai)50-85℃之間(jian)，其彈(dan)性模量(liang)僅為鋼的(de)1/3000，伸長(chang)率可達(da)1000%，拉伸到350%，后，縮回*變形僅為15%，天然橡(xiang)膠(jiao)手(shou)輪(lun)的(de)彈(dan)性較高(gao)(gao)，在(zai)通用橡(xiang)膠(jiao)手(shou)輪(lun)中僅次于(yu)順丁橡(xiang)膠(jiao)手(shou)輪(lun)。
　　天(tian)然(ran)橡膠(jiao)(jiao)手(shou)(shou)輪(lun)(lun)的(de)(de)強(qiang)(qiang)(qiang)(qiang)度(du)(du)在彈(dan)性材(cai)料中，天(tian)然(ran)橡膠(jiao)(jiao)手(shou)(shou)輪(lun)(lun)的(de)(de)生膠(jiao)(jiao)、混煉膠(jiao)(jiao)、liu化膠(jiao)(jiao)的(de)(de)強(qiang)(qiang)(qiang)(qiang)度(du)(du)都比較(jiao)高(gao)。未liu化橡膠(jiao)(jiao)手(shou)(shou)輪(lun)(lun)的(de)(de)拉伸強(qiang)(qiang)(qiang)(qiang)度(du)(du)稱為格(ge)(ge)林(lin)(lin)強(qiang)(qiang)(qiang)(qiang)度(du)(du)，天(tian)然(ran)橡膠(jiao)(jiao)手(shou)(shou)輪(lun)(lun)的(de)(de)格(ge)(ge)林(lin)(lin)強(qiang)(qiang)(qiang)(qiang)度(du)(du)可達1.4～2.5Mpa，適(shi)當的(de)(de)格(ge)(ge)林(lin)(lin)強(qiang)(qiang)(qiang)(qiang)度(du)(du)對于(yu)橡膠(jiao)(jiao)手(shou)(shou)輪(lun)(lun)加工成(cheng)型是必(bi)要(yao)的(de)(de)。天(tian)然(ran)橡膠(jiao)(jiao)手(shou)(shou)輪(lun)(lun)撕裂強(qiang)(qiang)(qiang)(qiang)度(du)(du)也(ye)較(jiao)高(gao)，可達98kN/m，其耐磨性也(ye)較(jiao)好。天(tian)然(ran)橡膠(jiao)(jiao)手(shou)(shou)輪(lun)(lun)機械強(qiang)(qiang)(qiang)(qiang)度(du)(du)高(gao)的(de)(de)原(yuan)因在于(yu)它是自補強(qiang)(qiang)(qiang)(qiang)橡膠(jiao)(jiao)手(shou)(shou)輪(lun)(lun)，當拉伸時會(hui)使大分子(zi)鏈沿應力方向取向形(xing)成(cheng)結晶(jing)。
