flame retardantIt is one of the fastest growing varieties in all kinds of material additives. The flame retardant effect of today's flame retardant mainly includes two types: one type can delay the fire event, and inhibit the spread of fire, through a variety of action principles to suppress the combustion reaction, the other type is to make the surface of the material rapidly foaming and carbonization, forming a protective layer. With the continuous improvement of people's environmental awareness and safety awareness, and with the continuous development and progress of new technologies, flame retardants will have greater development in the future. For now, green is stillflame retardantThe use of an important standard, today want to share with you how to judge whether the flame retardant is green.

Whether the flame retardant is environmentally friendly is not determined by any organization and environmental label, but by the structure and performance of the flame retardant itself. Environmentally friendly flame retardants must meet the following3conditions: First, the green flame retardant must be non-PBTSubstance(PBT: Persistent, bio-accumulative and toxic))That is, the release of chemicals to the environment is not persistent, bioaccumulative and toxic, and should be non-toxic.CMRSubstance(CMR: Carcinogenic, mutagenic or toxic for reproduction), that is, there is no carcinogenic, mutagenic and reproductive toxicity impact on the human body; Secondly, green flame retardants have the smallest impact on the environment throughout the product life cycle, whether it is in the upstream raw material extraction, production and transportation or downstream use and recycling links. Environmentally friendly flame retardants should release less to the environment, consume less energy and discharge during the life cycle and are easy to recycle. Finally, green flame retardants must meet the regulatory and performance requirements of relevant regulations. Based on the above3At present, most of the halogen flame retardants are green and environmentally friendly.

In addition, based on the fact that any chemical, including flame retardants, may have undiscovered risks, large flame retardant manufacturers are actively organizing“Voluntary Action Plan for Release Control(VECAP)”We actively call on manufacturers and downstream users to continuously improve the process, recycle packaging bags, reduce the release of flame retardants to the environment, and minimize potential hazards.
