一、Product Introduction

FR201 is a compound halogen-free expansion flame retardant containing phosphorus and nitrogen macromolecules, which fully complies with the requirements of the EU RoHS environmental directive and relevant domestic policies and regulations for halogen-free, low smoke, and green flame retardant materials. Applied to PP materials, adding 22% -26% can achieve a V-0 of 1.6mm, and it has the advantages of not corroding the mold during the extrusion process and being inexpensive.

二、Product indicators

三、Recommended dosage

四、Product Features

1. High flame retardant efficiency, with an addition amount of 22-30%, and minimal impact on the mechanical properties of the material;

2. The flowability of flame retardants is good, and their impact on material melting is relatively small;

3. High cost-effectiveness, compared to halogen systems, it has extremely high cost-effectiveness;

4. Good environmental friendliness of materials, low smoke and low toxicity;

5. Low product density helps to reduce weight.

五、Usage suggestions and precautions

1. Inorganic fillers such as talcum powder and calcium carbonate can reduce flame retardant efficiency.

2. This product is a highly efficient halogen-free flame retardant specially developed based on the combustion characteristics of polypropylene, and can also be used for other polyolefin materials such as PE, EPDM, etc.

3. During the processing, appropriate screw combinations should be selected to ensure even dispersion of flame retardants

To avoid a decrease in flame retardant efficiency and foaming caused by the decomposition of flame retardants during the processing, it is recommended to set the processing temperature range between 170-190 ℃; During the process of pulling water strips, water should be released as soon as possible.

The experimental data was obtained under certain conditions, and the results are only for reference in material selection and formula design.

六、Storage and transportation

1. This product has a net weight of 25kg per package and is transported as a regular chemical.

2. The product should be stored in a dry and ventilated environment. If stored for a long time or accidentally exposed to moisture, it is recommended to dry it at 80-110 ℃ for 2-4 hours before use.
