PFA plastic products are: PFA hose, PFA corrugated pipe, PFA spring tube, PFA rotary cutting tube and PFA heat shrinkable tube.
The following Shenzhen Dan Kai Teflon tube little sister for everyone to introduce:
commonality between the 1. several:
1.1. PFA plastic, soluble PTFE.
PFA plastic is a copolymer of a small amount of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene. The melt bonding is enhanced, the solution viscosity is reduced, and the performance is unchanged compared with PTFE.
. This kind of resin can be directly processed into products by ordinary thermoplastic molding methods. Suitable for the production of corrosion-resistant parts, wear parts, seals, insulation and medical equipment parts,
Insulation of high-temperature wires and cables, anti-corrosion equipment, sealing materials, pump valve bushings, and chemical containers.
1.2 common characteristics: ① operating temperature:-200 degrees to 260 degrees; ②, easy processing: can flanging, welding; ③, aging resistance: can be exposed to ozone, sunlight for a long time, not old
High transparency: the lowest refractive index in all plastics, can be very intuitive to see the flow of the medium in the tube. ⑤ Corrosion resistance: able to withstand in addition to molten alkali metals,
Fluorination medium and above 300 ° in addition to all strong acids, strong oxidants, strong reducing agents and various organic solvents.
Not commonly used characteristics: density: 2.16-2.20g/cm³;
Volume resistance> 1 × 1018; Surface resistance> 2 × 1013; Arc resistance> 165 seconds without leakage; Low water absorption: water absorption <0.1; Minimum friction coefficient: minimum friction coefficient; Table
Surface non-stickiness: known solid material head can not adhere to the surface; non-combustibility: the air will not burn, in line with the strict requirements of the fire place; non-toxic: non-toxic tasteless,
There is physiological inertia, no harm to people and the environment.
1.3 color: commonly used color: transparent, black, color; not commonly used color: yellow, brown, green, blue, etc.
2. the differences between PFA hose, PFA bellows, PFA spring tube, PFA rotary cut tube and PFA heat shrink tube:
2.1. PFA tube/PFA hose
1. Name: PFA tube, soluble polyethylene glycol propylene tube, transparent Teflon tube.
2. Common colors: transparent, black;
3. Uses: semiconductor manufacturing equipment, heat exchanger, steam piping, corrosive medium delivery pipe, wire and cable sheath, slot insulation pipe, all-inclusive fluorine-plastic O-ring pipe.
4. in stock are the common specifications: inner diameter * outer diameter (unit: mm) and other specifications can be customized
Metric: 2*4 3*5 4*6 5*7 6*8 8*10 8*12 9*12 10*12 12 12*14 14*16*18 18*20
Imperial: 1/8 inch (1.6*3.2),1/4 inch (3.96*6.35),3/8 inch (6.35*9.525),1/2 inch (9.5*12.7),3/4 inch
(15.88*19.05),1 inch (22.2*25.4);
Can produce specifications, inner diameter of 0.5mm to 200mm, wall thickness of 0.12mm to 3mm.

2.2 PFA bellows
1. Name: PFA corrugated pipe, 260 degree high temperature pipe, transparent Teflon corrugated pipe, soluble corrugated pipe, Teflon corrugated pipe;
Common specifications: (unit: mm) other specifications can be customized
Metric: outer diameter 6mm 8mm 10mm 16mm 20mm 25mm 38mm 60mm, etc;
Imperial: 1/8 inch, 1/4 inch, 3/8 inch, 1/2 inch, 3/4 inch, 1 inch.
PFA corrugated pipe uses:
1. It can be used as tubular reactor and exchanger in special occasions;
2. It can be used as the feeding and discharging pipes of tankers, storage tanks, containers and reaction kettles;
3, can be used to replace the low mechanical strength of graphite, ceramics, glass and other pipes;
4. It can be used for pipeline dislocation connection or to balance pipeline displacement, size change caused by climate or other reasons, or to eliminate the vibration of high frequency machinery.

2.3 PFA Bourdon Tube
Name: PFA spiral tube, PFA spiral tube, PFA spring tube
PFA spring tube uses:
1, liquid crystal manufacturing equipment; 2. Full-body single-ended light-emitting single-core optical fiber tube; 3. Heat exchanger and steam piping; 4. High purity reagent delivery pipe; 5. Various corrosive media (harsh
Solvent) delivery pipeline; 6, various frequencies of wire and cable sheath, slot insulation tube; 7, submersible motor slot insulation tube;
Tube for packing.

2.4 PFA rotary cutting tube
Material of PFA rotary cutting tube winding tube: made of FEP PFA PTFE material. The use method of PFA rotary cutting tube winding tube: first fix the starting point with a protective tape, and then press clockwise
To surround tight, you can wire bundle as a whole.
PFA rotary cutting tube winding tube product features: ① feel good, no peculiar smell; ② high temperature resistance; ③ with high insulation; ④ wear resistance; flame retardant; anti-aging; environmental protection; tensile; flame resistance; resistance to fire; resistance
High pressure.
The purpose of winding pipe: 1, optical fiber protective sleeve; 2, cable protection; 3, wire protection; 4, lighting equipment protective sheath.
The use of PFA rotary cutting pipe winding pipe installation method:
The use of winding pipe installation sub-machine installation and manual installation. Machine installation requires equipment similar to the hose water cloth winding machine style. Manual installation is briefly described as follows:
1. Turn the middle part of the hose (wire, cable) around the middle part of the flame retardant winding pipe, and start from the wound middle part to one end of the hose (wire, cable).
2. One end of the hose (wire, cable) is wound and positioned at the joint of the hose (wire, cable). After positioning, the spiral protective sleeve can be reversed and loosened to move freely,
Start from the wound middle part to the other end around.
3. The two ends of the flame retardant winding pipe are all wound around the outside of the hose (wire, cable) and the installation is completed.
Note: Multiple wires and cables can be branched for installation.
The use of PFA rotary cutting tube winding tube: as a protection wire from wear and insulation, and can improve the beauty of the wire bending. The main application field of winding pipe. Main application of winding pipe
In a variety of engineering machinery and mining hydraulic equipment and wear-resistant requirements of the wire and cable protection. Because it can completely cover the product to be protected, it forms an effective wear and UV protection.
It is used to protect many rod-shaped objects.
