交联聚乙烯的性质:
交联聚乙烯 英文简称XLPE,是提高PE性能的一种重要技术。经过交联改性的PE可使其性能得到大幅度的改善,不仅显著提高了PE 的力学性能、耐环境应力开裂性能、耐化学药品腐蚀性能、抗蠕变性和电性能等综合性能,而且非常明显地提高了耐温等级,可使PE 的耐热温度从70℃提高到90℃以上,从而大大拓宽了PE 的应用范围。目前,交联聚乙烯(XLPE )已经被广泛应用于管材、薄膜、电缆料以及泡沫制品等方面。
XLPE is an important technology to improve the properties of PE. The properties of PE modified by crosslinking can be greatly improved, not only the mechanical properties, environmental stress cracking resistance, chemical corrosion resistance, creep resistance and electrical properties of PE are significantly improved, but also the temperature resistance grade is significantly improved, and the heat resistance temperature of PE can be increased from 70 ℃ to more than 90 ℃, thus greatly broadening the scope of PE The scope of application of the system. At present, crosslinked polyethylene (XLPE) has been widely used in pipes, films, cable materials and foam products.
