Simple introduction of ETFE film raw material
- ETFE plastic- Ethylene tetrafluoroethylene
- Specific gravity: 1.7 g/cubic centimeter
- Molding shrinkage: 3.1-7.7%
- Molding temperature: 300-330 ℃
Physical property
- Long term use at a temperature of -80 to -220 degrees Celsius, it has excellent chemical corrosion resistance, is resistant to all chemicals, has the lowest friction coefficient among plastics, and has excellent electrical properties. Its electrical insulation is not affected by temperature, and is known as the “king of plastics”.
- Its chemical resistance is similar to that of PTFE, but better than PVDF.
- Its creep resistance and compressive strength are better than PTFE, its tensile strength is high, and its elongation can reach 100-300%. Good dielectric properties and excellent radiation resistance. 1. It is suitable for making corrosion-resistant parts, wear-reducing and wear-resistant parts, sealing parts, insulating parts and medical equipment parts.
- Wire and cable insulation, anti-corrosion equipment, sealing materials, pump valve bushings, and chemical containers.
ETFE Film performance
1. "The crystallization material exhibits low moisture absorption properties and can be transformed into products using standard thermoplastic processing techniques."
2. "The material exhibits low fluidity and is prone to decomposition, resulting in the release of corrosive gases upon breakdown. It is crucial to maintain a strict molding temperature that does not exceed 350 degrees Celsius. Additionally, the mold should be preheated to a range of 100 to 150 degrees Celsius, and the resistance within the pouring system to material flow should be minimized. This allows for the production of thin-walled, uncomplicated products with a thickness ranging from 0.7 to 0.8 mm."
3. "Transparent pellets can be processed through injection molding and extrusion molding techniques. The optimal molding temperature ranges from 300 to 330 degrees Celsius; exceeding 350 degrees may lead to discoloration or the formation of bubbles. For best results, high-speed and low-pressure molding methods are recommended, although it may pose challenges during the demolding process."
ETFE (F-40) fluoroplastics are obtained from DuPont in the United States and Asahi Glass in Japan, primarily for use in anti-corrosion linings. This material exhibits the exceptional corrosion resistance of polytetrafluoroethylene while also possessing strong adhesion properties to metals, effectively addressing the adhesion limitations typically associated with polytetrafluoroethylene. Additionally, its average linear expansion coefficient is comparable to that of carbon steel, making ETFE (F-40) an ideal composite material when combined with metals. Furthermore, it demonstrates outstanding resistance to negative pressure, enhancing its overall utility in various applications.
