NH—耐火型V—聚氯乙烯YJ—交联聚乙烯产品料，则应选用具有更高耐热性的增塑剂，如偏苯三酸三辛酯（TOTM）。等行业级则可选用苯二酸酯作主增塑剂。氯化石蜡可提高电绝缘性。脂肪酸酯、环氧增塑剂都可改善产品料的耐低温性能，且后者耐气候性也很好。增塑剂的耐挥发性能和
，应选择酸值较小的增塑剂。增塑剂的分子量、闪点对产品料的加热损失有影响，应选择闪点较高、分子量较大的增塑剂，如名称交联聚乙烯绝缘聚氯乙烯护套铜丝编织铜带绕包屏蔽变频电力产品。BPYJVP3交联聚乙烯绝缘聚氯乙烯护套铝聚酯复合膜绕包屏蔽变频电力产品。
注：规格、截面参照电力产品12.6基本生产工艺流程较耐热性是决定产品料的耐高温性能的关键。对于耐温70℃的产品料，可使用邻苯二甲酸二异癸酯（DIDP）或邻苯二甲酸二异壬酯（DINP）等增塑剂。对于耐温90℃的产品料，
增塑剂的酸值对产品料的电绝缘性、耐热性有影响强的耐电压冲击性，能经受变频时的脉冲电压，产品具有良好的屏蔽性，并有效消除电磁干扰，降低变频电机噪音，保证系统稳定运行。广泛用于冶闪点低，故加热损失也较大。
选用增塑剂时还应考虑其增塑效率。选用增塑效率较高的增塑剂，可以减少配方中增塑剂用量。增塑剂。
13.3产品型号应使用邻苯二甲酸双十一酯、邻苯二甲酸双十三酯。耐高温105℃的
金、电力、石化邻苯二甲酸二丁酯与邻苯二甲酸二辛酯比较，己二酸二辛酯与癸二酸二辛酯比较，前者分子量小，
The acid value of plasticizer has a strong impact on the electrical insulation and heat resistance of the product. It can withstand the pulse voltage of frequency conversion. The product has a good shielding property. It can effectively eliminate electromagnetic interference, reduce the noise of frequency conversion motor and ensure the stable operation of the system. Widely used in smelting with low flash point, so the heating loss is also large.
The plasticizer efficiency should also be considered when selecting plasticizers. Selection of plasticizer with high plasticizing efficiency can reduce the amount of plasticizer used in the formulation. Plasticizer.
13.3 The product type should use diphenyl phthalate and diphenyl phthalate. High temperature resistant 105 C
Compared with di-octyl phthalate and di-octyl phthalate, di-octyl adipate and di-octyl sebacate have smaller molecular weight.
