产品介绍

Halogens include: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and At (At). Among them, (At) is a radioactive element and hardly exists in products. The first four elements exist in products, especially in polymer materials.

According to EN61249-2-21, halogen-free PCB boards require bromine less than 900PPM, chlorine less than 900PPM, and the sum of chlorine and bromine less than 1500PPM. The halogen was tested by EN14582. Ionic halogen was formed after oxygen bomb burning. The halogen was tested by ion chromatography (IC).

Many well-known international enterprises have put forward halogen-free requirements. In general, EN61429-2-21 standard is adopted for halogen-free plastics. The contents of chlorine and bromine should not exceed 900 PPM, and the sum of chlorine and bromine should not exceed 1500 PPM. Halogens in plastics mainly come from halogen flame retardants.
