　Notes:
1. Appearance: National standard (GB209-2—6) requires that the main body is white and glossy, micro strip color is allowed.
2. Specification 99%-98% content is produced by membrane process; 96%-95% content is produced by diaphragm process.
3. Our company’s products all have white color and flake even.
