Plastics - Organic-perester crosslinking agents for unsaturated-polyester thermosetting materials - Determination of active-oxygen content

BS ISO 15038-1999 发布历史

This International Standard specifies a method of determining the total active-oxygen content of organic peresters. It applies to those peresters used to initiate crosslinking of unsaturated-polyester thermosets. The peresters most widely used in the crosslinking of unsaturated-polyester resins are given in Table 1. Butyl peresters may contain traces of tert-butyl hydroperoxide (TBHP), the active oxygen in which can be determined separately from that in the perester itself (see annex A). The active-oxygen content of the perester alone can then be obtained by subtraction.

BS ISO 15038-1999 在中国标准分类中归属于: G31 合成树脂、塑料基础标准与通用方法，在国际标准分类中归属于: 83.040.30 塑料的辅料和添加剂。
