Quality Control

Our CBD.SEASLS perfluoroether products are produced in 100,000-grade dust-free workshop:

• Air purification system: The cleanliness of the air is ensured by the three-stage filtration section, such as primary filtration, intermediate filtration and high-efficiency filtration.
• Temperature and humidity control: the temperature is usually controlled at 20-25℃ and the humidity is controlled at 45%-60% to meet the requirements of the production process.
• Airflow speed and distribution: The airflow speed is controlled at 0.2-0.5m/s to ensure uniform distribution of air mobility and cleanliness.
• Pressure control: Positive pressure design is adopted to maintain a certain positive pressure difference to prevent the entry of unclean air from outside.

In the production process of perfluoroethers, the role of class 100,000 clean room is mainly reflected in the following aspects:

• Prevent contamination: Through efficient air purification system and strict temperature and humidity control, prevent microorganisms and particles from entering into the production environment to ensure product quality.
• Improve production efficiency: Provide a dust-free and sterile production environment to reduce production interruptions and product quality problems caused by environmental factors.
• Ensure product quality: Ensure that the production environment for high-precision products, such as perfluoroether rubber, meets strict standards and improves product stability and reliability.

Installation requirements

• FFKM O-rings should be installed without scratching or twisting to ensure sealing effectiveness.
• The selection and use of FFKM O-rings need to be determined according to the specific application environment and requirements to ensure the best sealing effect and service life.
• Due to the high cost of FFKM materials, they are usually used in critical applications where high performance is required.
