PTFE Thread Seal Tape
PTFE Thread Seal Tapeis a commonly used accessories in the plumbing installation, for at the tube connections, enhance the tightness of the pipe connection at the raw material with the chemical name is polytetrafluoroethylene, the current HVAC and use ordinary white Teflon tape to the drainage, and natural gas pipelines and other specialized Teflon tape, in fact, the main raw material for PTFE, not merely some process.
The raw material with a novel ideal sealing material. Because of its non-toxic, odorless, excellent sealing, insulation, corrosion resistance, widely used in water treatment, natural gas, chemicals, plastics, electronics, engineering and other fields.
Chemical properties
Insulation resistance: from the environment and the impact frequency, volume resistivity of up to 1018 ohm · cm, dielectric loss, and high breakdown voltage.
High and low temperature resistance: the impact of changes in temperature, the temperature range of a wide range of use temperature of -190 to 260 ° C.
The self-lubricating properties: having a minimum coefficient of friction in the plastic, is the ideal non-oil lubricated material.
Surface non-tackiness: Known solid material does not adhere on the surface, is a minimum surface energy of the solid material.
Resistance to atmospheric aging, radiation-resistant properties and a lower permeability: long-term exposure to the atmosphere, the surface and the properties remain unchanged.
Incombustible: limiting oxygen index is 90 or less.
Physical properties
Polytetrafluoroethylene softer mechanical properties. Has a very low surface energy.
In practical application, liquid raw material instead of solid raw material with liquid raw material in the pipe thread sealant with high adhesive strength, good sealing, corrosion resistance, high temperature resistance, aging characteristics. Precision filtration devices quick installation, is currently the most advanced thread sealant. Widely used in industrial and civil fire, shipbuilding, gas, water, instrumentation, air conditioning, trachea, tubing, hydraulic tube pipe thread sealing and locking. |
