㈢ PE是什麼材料、特點、作用

PE材料介紹常用的有三大類，即：LDPE HDPE LLDPE 三種聚乙烯的單體是一樣，只不過，在合成這些聚乙烯
時，所採用的工藝條件不一樣，因此，才生成三種不同的聚乙烯品種，三種材料的性能有較大的差異。

LDPE
簡稱LDPE
俗稱花料或筒料
學名低密度聚乙烯高壓聚乙烯
英文名low density polyethylene
單體乙烯------是石油提煉中產生的一種氣體
本色聚乙烯本色是一種半透明白色臘狀材料，比重比水輕，柔軟而且有韌性，略能伸長，無毒，無味燃燒特徵易燃，離火後能繼續燃燒，火焰上端呈黃色，下端呈藍色，燃燒時會熔溶，有液體滴落，無黑煙冒出，同時，發出石臘燃燒時發出的氣味。
優點耐酸鹼，耐有機溶劑，電絕緣性優良，低溫時，仍能保持一定的韌性。
缺點機械性能差，透氣差，易變形，易老化，易發脆，易應力開裂，表面硬度低，易刮傷。難印刷，印刷時，需進行表面放電處理，不能電鍍，表面無光澤。
用途用於擠出包裝薄膜，被復薄膜，軟管
用於注塑低檔日用品及外殼
用於擠出吹塑容器
注塑性能低分子量的聚乙烯，熔點為120℃，非常象石臘；一般的聚乙烯熔點為140℃，分解溫度為
300℃；注塑溫度的可調區間較大，常用於其它原料的換料洗機用。注塑時，一般使用溫度為170℃--220℃；
因是烯烴類塑料，它不吸水，生產時，不需哄干，但為了產品質量，可用60℃溫度烘乾1hr，以排出浮水；
聚乙烯的熔體粘度大，流長比小，薄壁製品可能缺膠，因此，澆口和流道相對較大；製品易帶靜電，表面易
吸塵埃。收縮率為16‰；溢邊值為0.05mm

HDPE
簡稱HDPE
俗稱硬性軟膠
學名高密度聚乙烯低壓聚乙烯
英文名high density polyethylene
單體乙烯---石油提煉中產生的一種氣體
本色高密度聚乙烯本色是一種不透明白色臘狀材料，比重比水輕，柔軟而且有韌性，但比LDPE 略硬，也略能伸長，無毒，無味燃燒特徵易燃，離火後能繼續燃燒，火焰上端呈黃色，下端呈藍色，燃燒時會熔溶，有液體滴落，無黑煙冒出，同時，發出石臘燃燒時發出的氣味
優點耐酸鹼，耐有機溶劑，電絕緣性優良，低溫時，仍能保持一定的韌性。表面硬度，拉伸強度，剛性等機械強度都高於LDPE，接近於PP，比PP 韌，但表面光潔度不如PP
缺點機械性能差，透氣差，易變形，易老化，易發脆，脆性低於PP，易應力開裂，表面硬度低，易刮傷。難印刷，印刷時，需進行表面放電處理，不能電鍍，表面無光澤。
用途用於擠出包裝薄膜，繩索，編織袋，漁網，水管
用於注塑低檔日用品及外殼，非承載荷構件，膠箱，周轉箱
用於擠出吹塑容器，中空製品，瓶子
注塑性能一般的HDPE 熔點為142℃，分解溫度為300℃；注塑溫度的可調區間較大。注塑時，一般使用
溫度為180℃--230℃；因是烯烴類塑料，它不吸水，生產時，不需哄干，但為了產品質量，可用60℃溫度烘乾1hr，以排出浮水；聚乙烯的熔體粘度大，流長比小，薄壁製品可能缺膠，因此，澆口和流道相對較大；製品易帶靜電，表面易吸塵埃。收縮率為16‰；溢邊值為0.05mm

LLDPE
簡稱LLDPE
學名線型低密度聚乙烯低壓低密度聚乙烯
單體乙烯---石油提煉中產生的一種氣體
本色線型高密度聚乙烯本色是一種不透明白色臘狀材料，比重比水輕，柔軟而且有韌性，但比LDPE 略
硬，也略能伸長，無毒，無味
燃燒特徵易燃，離火後能繼續燃燒，火焰上端呈黃色，下端呈藍色，燃燒時會熔溶，有液體滴落，無黑煙冒出，同時，發出石臘燃燒時發出的氣味

LDPE HDPE LLDPE 三種材料的差別：LDPE 與HDPE 的差別主要是在密度上的差別，從而引起機械性能上的
差別，一個剛硬，一個柔韌；LLDPE 與它們的差別，主要是在分子結構上，LLDPE 有較多的支鏈，因此，這種材
料是即柔韌又剛硬。
優點耐酸鹼，耐有機溶劑，電絕緣性優良，低溫時，仍能保持一定的韌性。表面硬度，拉伸強度，剛
性等機械強度都高於LDPE，但低於HDPE；LLDPE 的抗穿刺性是最好的，耐撕裂，特別適宜生產薄膜，生產出的
薄膜比LDPE 薄，但強度高。
缺點機械性能差，透氣差，易變形，易老化，易發脆，脆性低於PP，易應力開裂，表面硬度低，易刮傷。難印刷，印刷時，需進行表面放電處理，不能電鍍，表面無光澤。
用途用於擠出包裝薄膜，膠帶，電纜；生產出的薄膜，也叫擬紙薄膜
用於注塑低檔日用品及外殼
用於擠出吹塑容器，中空製品，瓶子
注塑性能一般的LLDPE 熔點為170℃，分解溫度為300℃；注塑溫度的可調區間較大。注塑時，一般使用溫度為200℃--260℃；它的表觀粘度大，流動性差，單獨的LLDPE 難以注塑，因此，要加大注塑機的功率或加其它低分子量的塑料增加它的流動性；因是烯烴類塑料，它不吸水，生產時，不需哄干，但為了產品質量，可用60℃溫度烘乾1hr，以排出浮水；線型低密度聚乙烯的熔體粘度大，流長比小，流動性低於LDPE 和HDPE，薄壁製品可能缺膠，因此，澆口和流道相對較大；製品易帶靜電，表面易吸塵埃。收縮率為16‰；溢邊值為0.05mm
