Our PFA NFEP Film represents the next generation of release films for LCD/SLA/DLP resin 3D printers. Often referred to as nFEP (non-fluorinated ethylene propylene) or simply “FEP 2.0,”
our PFA film is engineered to significantly outperform standard FEP films in terms of release force, optical clarity, and durability .
Utilizing 100% virgin PFA raw material, Shenzhen Forbest ensures that every roll or sheet delivers consistent, high-quality results for professionals, hobbyists, and industrial users .
Whether you are printing intricate jewelry casts or large engineering prototypes, our film provides the reliable non-stick surface required for perfect prints every time.
2. Details & Comparison: Why Choose Forbest PFA over Standard FEP?
The shift from traditional FEP to PFA (nFEP) is driven by chemistry. PFA offers superior mechanical properties while maintaining the chemical inertness required to withstand harsh resin exposure. Below is a detailed comparison based on industry standards and Shenzhen Forbest manufacturing capabilities.
Parameter Table: PFA (nFEP) vs. Standard FEP
PFA (nFEP) vs. Standard FEP
| Parameter | Shenzhen Forbest PFA (nFEP) Film | Standard FEP Film | Why It Matters (Advantage) |
|---|---|---|---|
| Material Composition | 100% Virgin PFA (Perfluoroalkoxy) | Fluorinated Ethylene Propylene | PFA offers better mechanical strength at high temps. |
| Release Force | Extremely Low (50% less adhesion) | Standard | Reduces suction force on the LCD screen, preventing print failures and increasing screen lifespan. |
| Tensile Strength | ~40 MPa (5x Tougher) | ~6 MPa | Higher durability means the film resists stretching and dimpling, ensuring dimensional accuracy over many prints. |
| Light Transmittance | >95% | ~90-92% | Higher UV transparency allows for faster exposure times and better curing of fine details, enhancing 8K resolution capabilities. |
| Continuous Service Temp | Up to 260°C | ~200°C | Ensures stability even during exothermic reactions of thick resin layers. |
| Dimensional Stability | Excellent (Low deformation) | Good | Maintains tension across the vat for a perfectly flat printing surface. |
Key Features of Shenzhen Forbest PFA Film
-
Superior Non-Stick Properties: The low surface energy of PFA ensures that cured resin lifts away effortlessly. This “low release force” is critical for high-speed printing and supports the delicate structures common in jewelry and dental applications .
-
High Transparency for 8K Printing: With light transmittance exceeding 95%, our film allows maximum UV light to pass through to the resin. This ensures that even the finest details on high-resolution 8K screens are cured properly, leaving no detail behind .
-
Chemical & Heat Resistance: PFA is inert to nearly all chemicals. It will not swell or degrade when exposed to aggressive acrylic-based or epoxy resins. It reliably withstands the continuous operating temperatures of resin vats without warping .
-
Custom Manufacturing (Factory Direct): As a dedicated China manufacturer, Shenzhen Forbest offers unparalleled customization. We provide films in thicknesses ranging from 0.03mm to 0.3mm and widths up to 800mm . Whether you need pre-cut sheets for specific printer models or bulk rolls for industrial machinery, we can deliver.
-
Dual-Side Protection: Our films come with a protective layer on both sides to prevent scratches and dust contamination during installation . This ensures you are working with a pristine optical surface right out of the package.
Applications
-
LCD/MSLA 3D Printing: Ideal for printers from brands like Phrozen, Elegoo, Anycubic, and Creality .
-
DLP/SLA Industrial Printers: High thermal stability makes it suitable for engineering-grade resins.
-
Chemical Processing: Used as liners or diaphragms due to its chemical resistance.
