WDF PK K990GF30 is a grade produced by WDF through 30% glass fiber reinforcement modification based on PK material. It can be applied to Floor Washer components (such as roller brushes, brackets, gears, and other parts).
WDF PK K990GF30 is a grade produced by WDF through 30% glass fiber reinforcement modification based on PK material. It can be applied to Floor Washer components (such as roller brushes, brackets, gears, and other parts). Due to its long-term dimensional stability, low sensitivity of strength to humidity, and water absorption of approximately 0.5%, it can ensure product cleaning performance during use while also creating a more comfortable environment. Compared with PA66 materials, it is more suitable for applications in the cleaning industry.
About PK Materials:
Polyketone (abbreviated as POK or PK), also known as polyketone material, is obtained through the copolymerization of carbon monoxide and olefins (generally ethylene and propylene). Among them, ethylene is the main olefin monomer (currently), while propylene can be used as a third monomer to control melting point and other physical properties.
● PK is an engineering plastic with a backbone composed entirely of carbon atoms and exhibits high crystallinity.
● In terms of molecular structure, PK has high stability against water molecules due to the C=O bonds in its main chain, giving it excellent hydrolysis resistance and chemical resistance.
● Due to its unique molecular structure, PK also demonstrates outstanding wear resistance and low-temperature resistance. The material features low VOC emissions and high barrier properties, making it a versatile green and environmentally friendly material.
PK materials exhibit excellent chemical resistance. Except for strong acids and strong bases, PK is not affected by contact with other chemical solvents. This makes it highly suitable for daily use in household appliance components such as Floor Washer.
These properties not only ensure stable operation of components under various cleaning conditions but also extend their service life. By selecting PK materials, users can enjoy a more durable and reliable cleaning experience, thereby improving quality of life and reducing maintenance costs.
Chemical Resistance Comparison of PK
In addition, the molecular chain structure of PK is highly regular, making it a crystalline polymer material. During processing, compared with other engineering plastics, its faster crystallization rate can effectively shorten injection molding cycle time and improve production efficiency. In summary, the excellent properties of PK materials can reduce both the initial production costs and subsequent maintenance costs of Floor Washer components, thereby improving overall production efficiency and quality.
