PP是一種半結(jié)晶性材料。它比PE要更堅硬并且有更高的熔點。由于均聚物型的PP溫度高于0℃以上時非常脆，因此許多商業(yè)的PP材料是加入 1~4%乙烯的無規(guī)則共聚物或更高比率乙烯含量的鉗段式共聚物。共聚物型的PP材料有較低的熱扭曲溫度（100℃）、低透明度、低光澤度、低剛性，但是有有更強的抗沖擊強度。PP的強度隨著乙烯含量的增加而增大。PP的維卡軟化溫度為150℃。由于結(jié)晶度較高，這種材料的表面剛度和抗劃痕特性很好。PP不存在環(huán)境應力開裂問題。通常，采用加入玻璃纖維、金屬添加劑或熱塑橡膠的方法對PP進行改性。PP的流動率MFR范圍在1~40。低MFR的PP材料抗沖擊特性較好但延展強度較低。對于相同MFR的材料，共聚物型的強度比均聚物型的要高。由于結(jié)晶，PP的收縮率相當高，一般為1.8~2.5%。并且收縮率的方向均勻性比PE-HD等材料要好得多。加入30%的玻璃添加劑可以使收縮率降到0.7%。均聚物型和共聚物型的PP材料都具有優(yōu)良的抗吸濕性、抗酸堿腐蝕性、抗溶解性。然而，它對芳香烴（如苯）溶劑、氯化烴（四氯化碳）溶劑等沒有抵抗力。PP也不象PE那樣在高溫下仍具有抗氧化性。

特性：密度低；耐熱，不變形；高剛度；高表面強度；化學穩(wěn)定性好；無毒無害；
缺點：韌性一般，耐氧化性一般，耐磨強度一般，低溫時脆化，不可高姘焊接，易受天氣條件限制。
應用領域： 泵閥部件，飲用水污水管道，密封件，噴涂載體，耐腐蝕槽、桶，耐酸堿工業(yè)用,廢水,廢氣排放設備用,洗滌塔,無塵室,半導體廠及其相關工業(yè)之設備和機器,食品機械及斬板，電鍍工藝，玩具部件，牙醫(yī)用導管，廣泛用于化工，機械，電器及電子工業(yè)等結(jié)構材料
