Melt flow rate, abbreviated as MFR in this article. The level of MFR reflects the behavior of the polymer at high temperatures.
The flow properties of the melt in its molten state during processing; the higher the melt index, the better the flowability. In production
During the process, under the same processing conditions, the higher the melt index of the raw material, the more material passes through the mold per unit of time.
The more material, the thicker the product.
R2-1 is a stable and efficient melt index modifier that can be used in PP and PE. At high temperatures
In the environment, R2-1 decomposes into smaller molecules, acting on molecular chain segments, altering the molecular structure and molecules.
interactions, altering the viscosity and strength of the melt during processing, ultimately serving to adjust the melt index and improve
The effect of plastic processing performance.
Usage: R2-1 must be thoroughly mixed with the raw material before use. For example, it needs to be added
Work with 1000kg of raw material, and the addition amount is chosen to be 0.3%. That is, weigh 3kg of R2-1 and use a horizontal mixer.
A mixer or other types of blending equipment should thoroughly mix 1000kg of raw material with R2-1.
Then, the raw material mixed evenly with R2-1 is conveyed to the processing equipment for pelletizing or

Precautions: Avoid contact with metals such as iron and copper, and avoid exposure to reductants (such as amines),
Acids, alkalis, and heavy metal compounds (such as desiccants, accelerators, and fatty acid salts) are used together.
Please consult the relevant technical personnel.
