1. The difference between Ptfe Teflon tube and nylon tube
Teflon (sleeve) pipe is a special pipe made of polytetrafluoroethylene (PTFE commonly known as Teflon, plastic king) material after extrusion and sintering, drying, high temperature sintering, and shaping. Teflon is also called Teflon, Teflon, Teflon, Teflon, Teflon, PTFE, Plastic King, and Teflon in English. It is widely used in machinery, electronic appliances, automobiles, aerospace, and chemicals. , Computers, electric heating, military, communications and other important technology industries, such as miniature transformers.
Nylon was developed by the outstanding American scientist Carothers (Carothers) and a scientific research team under his leadership. It is the first synthetic fiber in the world. The emergence of nylon has given a new look to textiles. Its synthesis is synthetic A major breakthrough in the fiber industry is also an important milestone in polymer chemistry.
The density of Teflon is generally greater than 2, while the density of nylon is about 1.2. The density of the ptfe Teflon tube is relatively dense, and the high temperature resistance and hardness are relatively better, while the nylon tube is softer, and the high temperature resistance is worse than that of the ptfe Teflon tube, but because it is relatively soft, it can adapt to more terrain . In terms of price, ptfe Teflon tube is slightly more expensive than nylon tube.
Teflon tube product features
1. High chemical stability: can withstand all strong acids, including aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acids, etc., strong alkalis, strong oxidants, reducing agents and various organic solvents . It is very suitable for feeding high-purity chemicals.
2. Low coefficient of friction: The coefficient of friction is generally only 0.04, which is a very excellent self-lubricating material, and the coefficient of friction does not change with changes in temperature. 3
3. Excellent anti-sticking property, and the inner wall of the tube is not easy to adhere to colloids and chemicals.
4. Excellent aging resistance, can be used outdoors for a long time.
5. Excellent electrical insulation performance: PTFE is a highly non-polar material with good dielectric properties, great resistance, and a dielectric constant of about 2.0, which is the smallest among all electrical insulation materials.
6. Part of the tube has high transparency, and the internal fluid condition can be easily observed.
Teflon tube performance parameters
1. Withstand voltage: 150V-600V
2. Working temperature: -80℃~260℃
3. Melting point: 327℃
4. Flame retardancy: VW-1
5. Breakdown strength: 26KV/mm
6. Color: transparent, translucent, milky white.

2. Which Teflon tube is better?
Shenzhen Dankai Technology specializes in the production of FEP, PFA, PTFE and other fluoroplastic tube, rod, sheet and film products and other insulating materials. Teflon is also known as polytetrafluoroethylene, commonly known as plastic king, F4. It is made of suspended polytetrafluoroethylene resin by molding and can be made into plates, turned films, and tubes. It can be pressed and pushed into shape, and can be mixed with graphite to make plates, rods, packings, ropes, and raw material belts.
The main purpose:
1. Cover and protect the joint parts of the machine for chemical resistance and non-adhesive liquid transfer
2. Protection of the sensor
3. Non-adhesive metal balls
4. Drug coating under high temperature
5. Optical fiber cover
Due to the excellent performance of Teflon tube, it is now widely used in all walks of life.
Shenzhen DanKai Technology Co., Ltd. (ShenZhen DanKai Technology Co.,ltd.), whose predecessor is Dongguan Dandi Insulation Material Co., Ltd. Fluoroplastic Material Factory, established in 1998, specializes in FEP, PFA, PTFE and other fluoroplastic pipes R&D, production and sales of rod, sheet and film products and other insulating materials. The company has a senior R&D team with international standards and a production line of fluorine plastic products imported from abroad. Some fluoroplastic products have passed ISO9001, SGS, FDA certification, and have been fully affirmed by domestic and foreign cooperative customers such as Huawei, Foxconn, Midea, ZTE, Intel, and AirTAC. The main products of the company are: ①Tubes: Ptfe tube, Fep tube, Pfa tube, Pvdf tube; ②Heat shrinkable tube: Ptfe heat shrinkable tube, Fep heat shrinkable tube, Pfa heat shrinkable tube, Pvdf heat shrinkable tube; ③Plate rod Membrane: Ptfe board and rod film, Fep board and rod film, Pfa board and rod film, Pvdf board and rod film; ④Insulation materials: silica gel, PE, PVC, UPE, etc.; ⑤Special category: PFA imported connector, spiral tube, spring tube , Rotary cut tube, welding rod, tee, straight-through, gasket, joint, taper rod, flared tube, sealing tube, braided tube, bellows, etc. At the same time, fluorine plastic products of various specifications can be customized and processed according to customer requirements.
