カットスルー抵抗は、150℃で評価した。耐有機溶剤
性は、試験シートを常温のアセトン中に7日間浸漬後、
取り出して7字状に折り曲げ14日間常温で放置した後
、再び同様に折り曲げて割れの発生有無を調べた。低温
脆化性は、JIS規格C−3005に基づき一30℃で
行った。The results are shown in Table 1. In addition, high temperature heat deformability is 200℃
Evaluation was made based on the presence or absence of deformation after heating for one day. High temperature cut-through resistance was evaluated at 150°C. Organic solvent resistance was determined by immersing the test sheet in acetone at room temperature for 7 days.
After taking it out, folding it into a figure 7 shape and leaving it at room temperature for 14 days, it was folded again in the same way and examined for cracks. Low-temperature embrittlement was measured at -30°C based on JIS standard C-3005.
第1表 度と比較例して名かに軽度であった。Table 1 The symptoms were mild compared to the comparative example.
各実施は、高温熱変形性、高温カットスルー抵抗が良好
であって、さらに難燃性も良好であることが明らかであ
る。また、引張り強さは少なくとも1.0kg/m■:
、伸びは少なくとも50%あれば電線被覆材料として適
用可能と考えられ、各実施例はそれらの基準に合格して
いる。It is clear that each implementation has good high-temperature thermal deformability, high-temperature cut-through resistance, and also good flame retardancy. In addition, the tensile strength is at least 1.0 kg/m■:
If the elongation is at least 50%, it is considered to be applicable as a wire covering material, and each of the examples passed those standards.
