Extremely High Melt Flowability and Processability: With a melt flow index (MFI) as high as 80 g/10min at 380 °C, the melt viscosity is greatly reduced. This makes the grade exceptionally ideal for injection molding parts with long flow paths, thin walls, or complex geometric structures, significantly lowering production energy consumption and mold filling difficulty.
Superb Short-term and Long-term Thermal Stability: The material features a high melting point of 343 °C and a heat deflection temperature of 156 °C. Even under continuous high-temperature working conditions of 200 °C to 240 °C, it still maintains its original mechanical rigidity and an extremely low coefficient of linear thermal expansion for long periods.
High Toughness and Strong Mechanical Stress Resistance: As an unreinforced resin, its tensile strain at break reaches up to 25%, and its flexural modulus is 4300 MPa. It successfully achieves a perfect balance between rigidity and toughness, offering excellent resistance to fatigue, wear, and instantaneous high-pressure shocks.
Excellent Broad-frequency Electrical Insulation Characteristics: With a dielectric strength of 16 kV/mm and a volume resistivity reaching 1.0*10^14 ohms * cm, its dielectric constant and dissipation factor remain extremely low and stable across a very wide range of industrial temperatures and operating frequencies, making it an ideal insulating cladding material for harsh electromagnetic environments.
Top-tier Chemical Resistance and Low Water Absorption: The water absorption rates under saturated and equilibrium states are only 0.07% and 0.4% respectively. The material exhibits a natural immunity to the vast majority of acids, alkalis, organic solvents, and high-temperature water vapor, providing exceptional physical dimensional stability.
Electrical/Electronics and Semiconductor Manufacturing: Due to the extremely high purity and outstanding electrical insulation properties of ZYPEEK® 330G, it is frequently utilized to manufacture semiconductor wafer carriers, high-precision test sockets, LCD handling machinery components, and high-reliability industrial miniature connectors.
Automotive and Aerospace Industries: Leveraging its high flowability, high-temperature resistance, and oil resistance, it is primarily used for injection molding thin-walled sensor housings, gearbox thrust washers, wear-resistant bushings inside automotive engine compartments, as well as insulation protection clamps for aerospace wiring harnesses.
Medical Devices and Bio-analysis: Benefiting from the material’s natural resistance to high-pressure steam sterilization and excellent anti-leaching properties against formulations, it is widely applied in high-value medical equipment components that require repeated disinfection, such as endoscope handles, fluid distribution valves for blood analyzers, and dental instruments.
Precision Machinery and Industrial Pumps/Valves: In complex and variable environments like petrochemical and water treatment industries, this grade is directly extruded or injection molded into impellers inside pump bodies, corrosion-resistant valve seats, sealing gaskets, and lightweight, low-noise gears in mechanical transmissions.
Q1: What are the recommended drying conditions for ZYPEEK® 330G before injection molding or extrusion processing?
A: Although PEEK has an extremely low water absorption rate (saturated water absorption is only 0.07%), its surface will still adsorb trace environmental moisture during storage. To prevent hydrolytic degradation of molecular weight, bubble formation, or surface silver streaks during ultra-high temperature processing at 360 °C to 400 °C, mandatory dehumidification and drying must be performed prior to processing. The recommended drying conditions are: dry in a forced-air oven at 150 °C for 4 to 6 hours, or dry in a dehumidifying dryer at 120 °C for 4 hours, ensuring that the moisture content of the material before feeding is strictly controlled below 0.02%.
Q2: Compared with unreinforced PC or PMMA, what are the core advantages of ZYPEEK® 330G?
A: PC and PMMA belong to conventional engineering plastics or commodity plastics, and their continuous use temperatures are generally limited to below 100 °C. As a specialized semi-crystalline polymer, ZYPEEK® 330G has a melting point up to 343 °C, representing a generational leap in thermal performance. Its resistance to industrial solvents, strong acids, and alkalis is completely unmatched by PC or PMMA. Furthermore, although PC exhibits high impact resistance, ZYPEEK® 330G (with a flexural modulus of 4300 MPa) provides an entirely different dimension of ultra-high load-bearing capacity in terms of long-term fatigue resistance and high-temperature rigidity.
Q3: What is the status of environmental and food contact compliance (such as RoHS, UL, FDA) for Zhongyan ZYPEEK® 330G?
A: As a top-tier global manufacturer of specialty polyesters, Zhongyan High Performance Material strictly limits the use of heavy metals and halogens in the production of ZYPEEK® 330G pure resin pellets, making them fully compliant with EU RoHS and REACH regulations. Since pure PEEK itself possesses inherent flame-retardant characteristics (typically achieving a UL 94 V-0 rating without adding flame retardants), and its chemical purity is extremely high with strictly controlled residual monomers, this material widely passes FDA (U.S. Food and Drug Administration) food contact compliance certifications or related biocompatibility tests, meeting the stringent requirements of international export barriers.
