Applications of PTFE Restriction Blocks
Chemical IndustryDue to PTFE's corrosion and high-temperature resistance, PTFE restrictor blocks are commonly used in sealing and pipeline restriction for chemical equipment to prevent erosion and damage by corrosive media.
Machinery fieldPTFE's high lubricity and non-stick properties make PTFE restrictors suitable for mechanical components requiring reduced friction and wear, such as sliding bearings and guides.
Medical fieldThe non-toxicity and biocompatibility of PTFE make it suitable for components in medical devices such as artificial blood vessels and heart valves. In the medical field, PTFE restrictors may be used in specific medical devices or equipment to provide necessary restraint or constraint functions.
Other FieldsPTFE restrictor blocks may also be used in electronics, electrical, and aerospace fields to meet the special material performance requirements of these industries.
Manufacturing and processing of PTFE restricted blocks
PTFE has a high melting point, high melt viscosity, and is sensitive to shear in the amorphous state, prone to melt fracture, thus conventional thermoplastic molding processes like melt extrusion and injection molding are not suitable. The manufacturing of PTFE blocks typically involves sintering using a process similar to powder metallurgy, or mechanical processing (such as turning, milling, etc.) to shape and size the PTFE blocks as required.
