How to evaluate the performance and quality of halogen-free Fire retardant?

Publish Time: 2024-01-23
Evaluating the performance and quality of halogen-free Fire retardants typically involves the following considerations:

1. Flame retardant performance: Evaluating the performance of halogen-free Fire retardant is mainly based on its flame retardant effect. Common test methods include oxygen index test, vertical combustion test and horizontal combustion test, etc. Through these tests, the material's combustion performance, ignitability and smoke generation after combustion can be evaluated.

2. Chemical stability: The chemical stability of halogen-free Fire retardant under different conditions is an important factor in evaluating its quality. This includes evaluating its stability and anti-aging properties in environments such as high temperature, humidity, UV rays, etc.

3. Toxicity and environmental impact: Evaluate the toxicity and environmental impact of halogen-free Fire retardant, including potential risks to the human body and the environment. Some common evaluation indicators include volatile organic compound (VOC) emissions, hazardous substance release, and biodegradability.

4. Processability and cost-effectiveness: Evaluating the processability and cost-effectiveness of halogen-free Fire retardant can help determine its feasibility in practical applications. This includes considering factors such as the physical properties, solubility, processing temperature requirements and cost of the halogen-free Fire retardant.

In addition, you can also refer to relevant standards and specifications to evaluate the performance and quality of halogen-free Fire retardant, such as UL94, GB/T 2408, etc. It is recommended to seek professional testing institutions or consult experts in relevant fields when evaluating to obtain more accurate and comprehensive evaluation results.
