一、Product Introduction

FR601 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 less than 22% can achieve 1.6mm V-0; Talc powder and fiberglass can be filled in PP material. Compared to brominated antimony flame retardants, it has the advantages of not corroding molds during extrusion, being inexpensive, and having high flame retardant efficiency.

二、Product indicators

三、Recommended dosage

四、Product Features

1. High flame retardant efficiency, with an addition amount of 20-25%, 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. The low density of the product helps to reduce weight;

6. It can be filled with talcum powder and fiberglass appropriately.

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 purposes

Polyolefin materials such as PE, EPDM, etc.

3. During the processing, while ensuring the uniform dispersion of flame retardants, appropriate screw combinations and processing temperatures should be selected to avoid a decrease in flame retardant efficiency and foaming caused by the decomposition of flame retardants. It is recommended that the processing temperature range be between 170-190 ℃; During the process of pulling water strips, water should be released as soon as possible.

4. 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.
