Our Non-FEP (nFEP) films are a special blend of Teflon material. They were originally used in DLP and SLA machines (a different size) due to high requirements of those printers. Those FEP films sold by other brand LCD printers are not good enough for DLP and SLA. nFEP film is now available for LCD printers.
nFEP has a higher tensile strength and elongation at break. nFEP has a tensile strength of 21-31 MPa compared to 14.5-28 MPa for FEP. The elongation at break of nFEP is 260-300% compared to 240-300% So basically the force that it takes to break nFEP is higher AND it is stiffer compared to FEP. This likely leads to each layer being more easily removed when lifted because the PFA fights back more, and a longer life for nFEP films because of slightly higher crack resistance.
Our nFEP films are excellent quality: resistant to high temperatures (up to 220° C), chemical resistant, UV stable and provide the ultimate non-stick surface for 3D resin printing.
nFEP is perfectly smooth – smoother than FEP film – with great air permeability, which leads to less vacuum suction force. So you will have fewer failed prints compared to standard FEP film.
