No Compromises: Achieving High Strength AND High Flow in PVDF Injection Molding with SF-F22IE

For injection molding engineers, material selection is often a game of trade-offs. You usually have to choose: do you want a resin that flows easily into complex molds (High MFR), or do you want a part that withstands high mechanical stress (High Tensile Strength)? Typically, increasing flow reduces mechanical integrity.

At FluorinChem, we believe you shouldn't have to choose.

Introducing PVDF Pellet SF-F22IE, our premium emulsion-polymerized grade designed to deliver superior mechanical performance without sacrificing processability.

The Engineering Paradox: Solved

The SF-F22IE grade stands out in the fluoropolymer market due to its unique balance of properties. While standard grades might offer a tensile yield strength of 30-35 MPa, SF-F22IE delivers a Tensile Strength at Yield of >45 MPa.

This 30% increase in strength is critical for safety-relevant components, such as:

· Chemical Pump Housings: Withstanding internal fluid pressure without ballooning or cracking.

· Industrial Valve Bodies: Maintaining dimensional stability under high torque and thermal cycling.

Remarkably, this strength comes with an incredibly versatile Melt Flow Rate (MFR) range of 8–26 g/10min. This broad processing window allows molders to fill large, thin-walled parts or multi-cavity molds with ease, reducing reject rates caused by short shots.

Technical Deep Dive: Why SF-F22IE?

Designed specifically for the rigorous demands of the Pump, Valve, and Fitting industries, SF-F22IE offers:

· Superior Impact Resistance: With a Notched IZOD Impact Strength of 80–100 J/m, it resists brittle failure from water hammer effects or accidental impacts in the factory.

· Rigidity: A Flexural Modulus of 2000–2300 MPa ensures parts hold their shape under load.

· High Purity: Prepared via VDF emulsion polymerization, ensuring low extractables for sensitive applications.

· Extreme Chemical Inertness: Like all our PVDF grades, it remains unaffected by most acids, aliphatic hydrocarbons, and aromatic solvents.

Ideal Applications

SF-F22IE is not just a resin; it is a solution for your most challenging projects:

· Centrifugal Magnetic Drive Pumps: The high strength ensures the containment shell can handle system pressure.

· Complex Filter Housings: The high flow rate allows for the molding of intricate internal ribbing and support structures.

· Semiconductor Fluid Handling: Where purity meets mechanical reliability.

Upgrade Your Component Reliability

If your current PVDF parts are failing under stress, or if you are struggling to mold complex geometries with stiffer resins, SF-F22IE is the upgrade you need.
