The raw material tape is a novel and ideal sealing material. Because of its non-toxic, odorless, excellent sealing, insulation, corrosion resistance, are widely used in water treatment, natural gas, chemical, plastic, electronic engineering and other fields. The following Xiaobian introduces the relevant knowledge of raw material belt.
Application of raw tape
Polytetrafluoroethylene can be molded by compression or extrusion; it can also be made into an aqueous dispersion for coating, impregnating or making fibers. PTFE is widely used in high-temperature, low-temperature and corrosion-resistant materials, insulating materials, and anti-stick coatings in the atomic energy, aerospace, electronics, electrical, chemical, mechanical, instrumentation, construction, textile, and food industries.
The main role of expanded PTFE raw material with 100% PTFE as raw material, it has micro-slender fibers and knots composed of net bulky structure. The expanded PTFE raw material tape has the characteristics of good toughness, high longitudinal strength and easy deformation in the transverse direction. It is an ideal material for disk and thread sealing. However, it cannot be used in contact with high concentrations of oxygen or liquid oxygen.
The nature of raw tape
Chemical properties
Insulation: It is not affected by the environment and frequency, the volume resistance can reach 1018 ohm·cm, the dielectric loss is small, and the breakdown voltage is high.
Resistance to high and low temperature: little effect on temperature, a wide range of temperature range, the use of temperature -190 ~ 260 °C.
Self-lubricity: With the smallest friction coefficient in plastic, it is an ideal oil-free lubricant.
Non-stick surface: No known solid material can adhere to the surface. It is a solid material with minimal surface energy.
Resistance to atmospheric aging, radiation resistance and low permeability: long-term exposure to the atmosphere, surface and performance remain unchanged.
Incombustible: The oxygen limiting index is below 90.
2. Physical properties
The mechanical properties of PTFE are soft. Has a very low surface energy.
In practical applications, many liquid raw material tapes are used to replace the solid raw material tapes. The liquid raw material has high adhesive strength, good sealing performance, corrosion resistance, high temperature resistance, and aging resistance in the pipeline thread sealant. Precision filter device , Fast installation, is currently the most advanced thread sealant. Widely used in fire protection, shipbuilding, natural gas, water, instrumentation, air conditioning, gas pipe, tubing, hydraulic pipe and other industrial civil pipeline thread sealing and locking.
Raw material specifications
Because the raw material tape has a very wide range of uses, in order to meet the needs of various industries, the raw material tape currently has a variety of specifications. The specifications of the general raw material tapes are: widths of 12mm, 19mm and 25mm; thicknesses of 0.075mm to 0.2mm; lengths of 10m to 50m. In addition, if we need to use a special type of raw material tape, we can also contact the manufacturer of the raw material belt to make a custom.
