陶氏AXELERON™ FO 8864 BK CPD 是一种高分子量、线性、中等密度的、黑色聚乙烯材料,是为光纤和普通金属导体电缆护套的应用而开发的。这种材料具有非常好的加工特性,可制成非常强韧的电缆护套。陶氏的AXELERON™ FO 8864 BK CPD亦具备优异的耐环境应力开裂性能、耐候性能以及抗热氧化降解性能。 陶氏 AXELERON™ FO 8864 BK CPD 在光纤电缆护套应用领域提供优异的低温光信号衰减性能。该材料结合了减小挤出回缩应力与优异的拉伸模量。因此,最大程度地减小了在温度周期变化过程中电缆护套对光纤电缆所施加的收缩力。 规格 陶氏AXELERON™ FO 8864 BK CPD 符合以下原材料规格的要求: ASTM D 1248:第 II类型,C级,第4类,E9和J4等级 联邦LP-390C:第 III类型,M级,2、3等级,第4类 REA PE 39 和89(原材料部分) AXELERON™ FO 8864 BK CPD is a high molecular weight, linear medium-density polyethylene black compound ("CPD") developed for fiber optic and conventional metallic conductor cable jacketing applications. The compound has very good processability and provides a tough cable jacket. AXELERON™ FO 8864 BK CPD also provides excellent resistance to environmental stress cracking and to weathering and thermal-oxidative degradation. AXELERON™ FO 8864 BK CPD provides excellent low temperature optic signal attenuation performance in fiber optic cable jacketing applications. The compound combines reduced extrusion shrinkback stress with excellent tensile modulus properties. This minimizes the contractive forces exerted by the cable jacket on the optic cable core during temperature cycling. Specifications AXELERON™ FO 8864 BK CPD meets the following raw material specifications: ASTM D 1248: Type II, Class C, Category 4, Grades E9 and J4 Federal LP-390C: Type III, Class M, Grades 2, 3, Category 4 REA PE 39 and 89 (Raw Material Sections) |
