PTFE resin

PTFE resin chemical name: Polytetrafluoroethylene(PTFE).

PTFE resin chemical formula: –(CF2CF2)n–.

PTFE resin operation and storage:
Operation: In the area of dust can place at a suitable exhaust ventilation.
Storage: Keep container tightly closed, well-ventilated place. Place in a dry place.

Hand protection: Wear gloves. Gloves must be inspected before using. Use appropriate gloves remove technique (without touching gloves outer surface) to avoid skin contact. After using, standardized treatment of contaminated gloves and proper laboratory in accordance with the law applicable. Washing and drying hands.

PTFE tape machine flow chart as below:

PTFE resin → add suitable and not high cost kerosene → Mixing together → Ripeing → Preforming (Water temperature under suitable degree) → Extrusion (Roller temperature under suitable degree) → Calender to tape shape→Degrease (Control the temperatuer by our machine ) → Stretch to Teflon tape → Wrapping on plastic wheel by skillful worker or by automatic wrapping machine.

The factors of effecting raw material quality:

1, The resin quality: PTFE resin quality determines the quality of Teflon tape.

2, Generally adopts the extrusion-agent of low boiling point, less impurities, volatile aviation kerosene,
If the extrusion-agent added too small, so that preforming PTFE rod cracking, extruded rod will be hard, and difficult to extrusion;
If the extrusion-agent added too large, the extruded rod will be too soft, the density can’t reach the requirement, resulting the stretched Teflon tape transparent and easy to break.

3, Ripeing temperature and time:
Ripeing temp too low time too short will not reach the resin ripeing effect, then will reduce the permeability of kerosene;
Ripeing temperature too high will cause burn, so it is better to control temperature , Ripeing time generally under controlled.

4, Extrusion pressure and speed:
Extrusion pressure too high or too low are both inappropriate, since it affects the Teflon tape density and forming effects, over quick extrusion speed causes the extruded rod soft, over slow extrusion speed impact extrusion type and efficiency, the extrusion pressure is generally controlled at 80 ~ 100kg/cm2.

Teflon tape machine

We are the very first one to manufacture teflon tape machine which own many patents in this field and accumulated a wealth of experience. More than 200 teflon tape machine we manufactured running in good condition in the whole world. Not only could we provide you the complete production line, but also help you to make money in this project at long run.

So, the is the details of raw materail which teflon tape machine can produce?

Teflon tape definition:
Also known as PTFE tape, which is abbreviation of tetrafluoroethylene and polymer.

The basic structure of teflon:
The basic structure of PTFE is – CF2 – CF2 – CF2 – CF2 – CF2 – CF2 – CF2 – CF2 – CF2 – CF2 -.

Teflon tape application:
PTFE is widely used in a variety of needs, such as: anti-acid and organic solvents, which itself has no toxic to people, but one of the raw materials used in the production process of ammonium perfluorooctanoate (PFOA) is considered likely to have a carcinogenic effect.

Teflon molecular:
Large relative molecular of PTFE, the lower one as hundreds of thousands, while higher one can up to one million or more (degree of polymerization of 104 orders of magnitude, while the polyethylene only 103). Degree of crystallinity is generally 90 to 95%, a melting temperature of 327 ~ 342 ℃. Molecule CF2 unit in PTFE arrange by zigzag shape, because the fluorine atom radius larger than the hydrogen, so the adjacent CF2 units can not cross exactly trans orientation, but form a spiral twisted chain, fluorine atom covering almost the entire polymer chain surface. This molecular structure explains various properties of PTFE. At temperatures below than 19 ℃ to form 13/6 helix; phase transition at 19 ℃, slightly unravel the molecular to form 15/7 helix.

Though the perfluorocarbon carbon – carbon bond and carbon – fluorine bonds are broken need to absorb energy 346.94 and 484.88kJ/mol, but PTFE depolymerization energy generate 1mol tetrafluoroethylene only need 171.38kJ. So in the pyrolysis, PTFE mainly depolymerizate tetrafluoroethylene. PTFE at 260,370 and 420 ℃ the weight loss rate (%) were 1×10-4, 4×10-3 and 9×10-2 per hour.

Briefly introduction of PTEF tape made by ptfe tape machine:

Teflon tape commonly used as a water pipe installation aids for pipe connections, enhanced sealing between duct connection.

PTFE tape with a chemical name polytetrafluoroethylene, which is commonly used in plumbing area plain white teflon tape, and gas pipelines also have special teflon tape. In fact, the main raw material is polytetrafluoroethylene, only the technical processes are not the same.

PTFE tape is a novel ideal sealing material. Because of its non-toxic, odorless, excellent sealing, insulation, corrosion resistance, is widely used in water treatment industry, natural gas area, chemicals field, plastics, electronics engineering and other fields.

PTFE tape adopts advanced production technology machine, good quality, complete specifications, to meet different customer requirements of different industries.
Product has extremely excellent insulation, strong chemical stability and good sealing performance, it is widely used in mechanical, chemical, metallurgy, electric power, shipbuilding, aerospace, medicine, electronics and other industrial fields.

The main role of PTFE tape:
With 100% PTFE as raw material, it has a fine mesh expanded long fiber structure and composition of the section. Expanded teflon tape having a good toughness, high longitudinal strength, transverse easy deformation characteristics. It is ideal material for application of threads and sealing. But it can not apply in high concentrations of oxygen or liquid oxygen contact occasions.
