Kynar 1000 PVDF | Enhanced Toughness in Chemically Aggressive Environments
Kynar 1000 is a high molecular weight PVDF supplied as extruded rods and plates. Designed for machined parts that require excellent chemical resistance with improved toughness, impact resistance, and long-term durability.
What Kynar 1000 offers
Performance characteristics that make Kynar 1000 the preferred choice for demanding applications requiring both chemical resistance and mechanical durability.
Higher stiffness and rigidity
Glass fiber reinforcement significantly increases stiffness, making PEEK GF30 well-suited for structural components that must resist bending and deflection.
Improved dimensional stability
Lower thermal expansion and reduced creep enable machined parts to maintain tight tolerances under mechanical load and temperature variation.
Strong mechanical performance under load
Provides higher tensile and flexural strength compared to unfilled PEEK, supporting demanding load-bearing applications.
Better performance for thin-walled and precision parts
The added rigidity supports designs where thinner sections or tighter tolerances are required.
Reliable performance in harsh environments
Maintains stability in environments with heat, mechanical stress, and exposure to fuels, oils, and industrial chemicals.
Common components made from Kynar 1000
Typical machined parts requiring chemical resistance with added toughness.
Corrosion-Resistant Structural Components
