Excellent Material: High-strength PA66 material, with light weight, fatigue resistance characteristics, easy to clean, can be reused, save money. PA66 plastic has a higher melting point in polyamide materials. It is a semi-crystalline - crystalline material. PA66 can also maintain strong strength and stiffness at higher temperatures, because of its self-wetting and good friction resistance. It can be used for a long time below 150 degrees. 4. The surface is carefully designed according to the human body. The function of the front four plastic blades is to clean the grease on the surface of the grease nozzle, prevent the dust in the air clinging on the surface of the grease nozzle.
