lending modification is usually the most commonly used modification method for PEEK materials. Generally, fibers, metal oxides, inorganic fillers and other high molecular polymers such as PTFE can be added to the raw materials. The PEEK composite material prepared by this method can improve the defects of PEEK by using the composite effect, and improve the comprehensive properties of the material to a great extent.
The most commonly used glass fiber filled peek content is 30%. The name of this material in Junhua is PEEK5600GF30. Compared with PEEK unfilled, the PEEK material filled with glass fiber can improve higher hardness, strength and better heat resistance. The thermal deformation temperature of PEEK filled with glass fiber can be increased from 160 ℃ to over 300℃. Compared with this, the disadvantages of glass fiber modification are that it is more difficult to process, and the toughness and electrical properties are decreased compared with PEEK unfilled.
According to the liquidity, it can be subdivided into: PEEK3600GF30; PEEK5600GF30; PEEK7600GF30；
Carbon Fiber Filled PEEK
The most commonly used carbon fiber filled peek content is 30%. The name of this material in Junhua is PEEK5600CF30. Compared with PEEK unfilled, the PEEK material filled with carbon fiber can improve higher hardness, strength, better heat resistance and friction characteristics. The modified peek filled with carbon fiber can be increased from 160 ℃ to over 300℃. Compared with this, the disadvantages of its carbon fiber modification are that it is more difficult to process, and the toughness is reduced. At the same time, due to the addition of carbon fiber, it has conductive characteristics.
According to the liquidity, it can be subdivided into: PEEK3600CF30; PEEK5600CF30; PEEK7600CF30；
PEEK HPV
PEEK HPV is a peek material with low friction coefficient and good wear resistance. Among them, peek accounts for 70%, PTFE accounts for 10%, graphite accounts for 10%, and carbon fiber accounts for 10%. The name of this material in Junhua is PEEK5600LF30. The filling of graphite and PTFE can well reduce the friction coefficient of the material, and can still reduce the energy consumption and noise in the use process without using the lubricating medium; The addition of carbon fiber can improve the rigidity of the material. Compared with other brands, its disadvantage is that its brittleness is large, that is, its impact strength is small.
According to the liquidity, it can be subdivided into: PEEK3600LF30; PEEK5600LF30; PEEK7600LF30；
