When decorating a house, we all know that a lot of decoration materials are needed. When choosing these decoration materials, we found that there are many brands and types of them. Teflon coatings can reduce product costs and improve production efficiency in many ways. It can also be used to directly address product problems to improve product quality and increase sales.
Teflon coating is a unique industrial coating with excellent properties that other industrial coatings cannot match. The high-tech performance of Teflon coatings can reduce product costs and improve production efficiency in many ways. It can also be used to directly solve problems with your product to improve product quality and increase sales.
Teflon coating is the originator of non-stick coating, which combines heat resistance, chemical inertness, excellent insulation stability and low friction, and has comprehensive advantages that other coatings cannot compete with.
Teflon industrial coatings are available in powder and liquid forms. 200 kg teflon powder, The flexibility of product application allows it to be used on almost all shapes and sizes of products, and the added value of Teflon coatings to products far exceeds the value of non-stick coatings themselves.
What are the characteristics of Teflon coating？
1. High temperature resistant working temperature up to 250℃. Low temperature resistance has good mechanical toughness; 5% elongation can be maintained even when the temperature drops to -196°C. Corrosion resistance – inert to most chemicals and solvents, strong acid and alkali resistance, water and various organic solvents.
2. Teflon coating pipe has the best aging life among plastics in weather resistance. High lubrication has the lowest coefficient of friction of solid materials. Non-stick is the smallest surface tension in a solid material that does not stick to anything. Non-toxic – It is physiologically inert, and it has no adverse reactions when it is implanted in the body as an artificial blood vessel and an organ for a long time. Electrical insulation can resist high voltage electricity of 1500 volts.
3. The relative molecular weight of Teflon coatings is relatively large, the low is hundreds of thousands, the high is more than 10 million, generally millions (the degree of polymerization is in the order of 10^4, while the polyethylene is only 10^3) . Generally, the crystallinity is 90-95%, and the melting temperature is 327-342 °C.
4. The CF2 units in the Teflon coating molecule are arranged in a zigzag shape. Since the radius of the fluorine atom is slightly larger than that of the carbon, the adjacent CF2 units cannot be completely oriented in trans, but form a helical twisted chain. Covers almost the entire surface of the polymer chain. This molecular structure explains the various properties of Teflon coatings. At temperatures below 19°C, a 13/6 helix is formed; at 19°C, a phase transition occurs, and the molecules unwind slightly, forming a 15/7 helix.
