Shanghai Witlan Industry Co., Ltd.

With the features of etfe film, weather resistance, transparency and excellent mechanical strength, etfe film is widely used for architectural purposes for solar-cell, roofing material, agriculture film, etc. The highest mechanical strength in fluorine resin about 120 , , the elongation is the largest. Excellent radiation resistance in fluorine resin. Excellent incombustible properties (limit oxygen index 31vol%, ul94v- 0). Usually, it is not corroded by acid, alkali, or organic solvents.

FEP Film has the characteristics of extremely excellent heat resistance, chemical resistance, non-stick and non-flamability capabilities, and is suitable for mold releasing film since it also has heat adhesiveness (heat seal) and adhesiveness (surface treated on one side) simultaneously.

Product features , based on our proprietary ir management plastic technology, witlan irf series ir pass plastic film is transparent to 800-1600nm ir wavelength, while blocks 300-700nm uv and visible light. , witlan ir pass film is dark or black colored and different thickness (0.05mm, 0.25mm, 0.50mm & 0.80mm) available. Applications , witlan ir pass film is used as ir window or visible light shielding for various applications such as ir surveillance devices, cameras, instruments, lasers, and various other optical devices.

Main features: High light transmittance, uv light through rate reach 92%, shorter curing time, better curing effect, higher print accuracy. More durable, release more than 30, 000 times (refer to the printed page); Be suitable for a variety of types of uv curing light 3d printers. Size a: peel off the protective film directly from the 3d menbrance, and then stick the base layer on the glue tank, instead of using a silicone membrane, it is more convenient to use. Size b dont have back glue, so it need glue tank around a fixed at the bottom of the device. Size: 210 * 290 mm
