Detailed explanation of the use steps: Let BASF antioxidants perform good

To give full play to the performance advantages of BASF antioxidants, the correct use method is crucial.The following are detailed operation steps and precautions to help users achieve good application results:

Step 1: Accurate weighing

Precisely weigh the required amount of antioxidant according to the formula requirements. It is recommended to use an electronic balance for weighing, with the accuracy of 0.1g. If the formula does not specify the dosage, it can usually be added in the following ratio:

For ordinary plastic products: 0.1%-0.3%
For high-performance engineering plastics: 0.3%-0.5%
For rubber products: 0.2%-0.4%

Step 2: Fully mix

Add a well-deserved antioxidant together with a base resin or other additives into a high-speed mixer. The mixing time is generally controlled at 5-10 minutes, and the rotation speed is set between 800-1200rpm. To ensure uniform mixing, a step-by-step addition method can be used: first add half of the antioxidant for preliminary mixing, and then add the remaining part to continue stirring.

Step 3: Granulation or direct processing

For processes that require granulation, it is recommended to use a twin screw extruder. Set the appropriate processing temperature, usually between 200-240°C. During the extrusion process, attention should be paid to the plasticization and color changes of the material. If the material color is found to be abnormally darkened, it may indicate that the processing temperature is too high or the residence time is too long, and the process parameters need to be adjusted in time.

Step 4: Quality Inspection

After the processing is completed, the finished product should be tested for performance, including key indicators such as tensile strength, impact strength, and melting index. At the same time, the appearance quality and dimensional accuracy of the product need to be checked. If the test results are not ideal, the amount of antioxidant can be adjusted appropriately or the processing process can be optimized.

Precautions:

Antioxidants should be stored in a dry and cool place to avoid direct sunlight.
The antioxidants after opening should be used as soon as possible. If they need to be stored for a long time, it is recommended to seal and place them in a low-temperature environment.
When using it, appropriate protective equipment, such as gloves, masks, etc., should be worn to prevent dust from inhaling or contacting the skin.
Antioxidants of different grades may have mutual influence. It is recommended to store them separately to avoid mixed storage.

Through the above steps, it can be ensured that BASF antioxidants can perform well in practical applications. Each link needs to be strictly controlled to achieve ideal antioxidant protection.
