What is the difference between pure PTFE lining and filled PTFE lining?

Pure PTFE has the best corrosion resistance but poor creep resistance. Filled grades improve wear resistance, compressive strength and dimensional stability, but slightly reduce chemical resistance and non-stick performance.

AI-Powered supplier vetting

SummaryZHENJIANG HANSA SEALANT CO., LTD. is described as a factory producing plastic profiles, seals, and custom products based on samples or drawings. Recorded trade data shows three gasket-sheet transactions associated with one buyer in the Philippines, each with one transaction, and supplier registration in May 2025. The supplier states that it provides professional after-sales support, including transportation coordination and quality assurance. An SGS audit record identifies plastic products and seals as the primary products, but the audit result is recorded as “0,” and the report expired on July 22, 2025. Evidence is insufficient to confirm current certifications, financial credibility, innovation systems, manufacturing capacity, or broader customer references.

Supplier typeThe supplier is identified as ZHENJIANG HANSA SEALANT CO., LTD. and described as a factory producing plastic profiles, seals, and related gasket products. The SGS record classifies its primary products as plastic products and seals, supporting classification as a manufacturer rather than only a trading intermediary.

After-Sales capabilityThe company explicitly promises professional after-sales service covering transportation coordination and quality assurance. This is direct evidence of a stated service commitment, although the slices do not document performance metrics or case outcomes.

Customization capabilityThe company explicitly states that it makes products based on customer samples or drawings, directly supporting customization capability. The absence of confirmed private-mold R&D or 3D design service information prevents assessment of the full scope of its customization resources.

Client casesTrade records identify FRANCHIZ SERVICES INC as an associated buyer in the Philippines and document three gasket-sheet product transactions. This provides one identifiable customer case, but the limited number of recorded transactions does not establish a broad or diversified customer portfolio.

Product Q&A

Q:What bonding methods are used for PTFE lining?

Common methods include adhesive bonding, sintering, mechanical fixing, and loose lining design according to pressure and temperature requirements.

Q:In which equipment is PTFE lining commonly applied?

It is widely used in reaction vessels, pipes, valves, pumps, storage tanks, and heat exchangers in chemical, pharmaceutical, semiconductor, and electroplating industries.

Q:What is the difference between PTFE lined pipe and lined valve in terms of lining process?

PTFE lined pipes usually adopt paste extrusion or sinter lining, while lined valves often use molded lining or electrostatic powder coating to ensure uniform thickness in complex cavities.

Q:How to prevent PTFE lining from peeling or debonding under high temperature and pressure?

Common solutions include surface etching treatment of metal substrate, using high-temperature resistant adhesives, adding mechanical anchoring structures, and selecting filled PTFE materials to reduce thermal expansion difference.

Q:What is the effect of vacuum conditions on PTFE lining, and how to solve it?

PTFE lining is prone to collapse or deformation under negative pressure. Solutions include adding support rings, using rigid backing layers, or adopting bonded lining with enhanced adhesion.
