Focused on biocompatibility, pore structure, flow resistance evaluation, sterilization compatibility, and documentation support. (Samples and third-party testing available)
What are the main features and advantages of the PBT blood filtration membrane?
PBT offers excellent mechanical and chemical stability, low moisture absorption, and good biocompatibility—making it suitable for filters that contact blood or plasma. Its meltblown microporous structure balances particle retention and flow, while proper support and edge-sealing designs enhance overall reliability.
Can it be used for blood-contact applications? What testing is required?
The final product should undergo risk assessment and validation under actual process conditions. Third-party testing can be arranged to verify compliance as required. We can coordinate testing and documentation under an NDA as part of project support.
How are pore size and filtration performance defined and verified?
Pore size and structure can be adjusted based on application needs to achieve the desired balance between flow rate and retention efficiency. Actual performance may vary depending on basis weight, thickness, and processing conditions; we recommend confirming final parameters through sample testing or pilot-scale evaluation.
How should flow rate and pressure drop be evaluated? Can you provide standard data?
Flow and pressure drop depend on factors such as pore size, basis weight, number of layers, and the type of liquid. We can provide sample rolls or sheets and offer basic testing guidance to help you obtain valid data under your target conditions.
Is this membrane intended for single-use or can it be reused?
The use mode depends on product design and regulatory requirements. While PBT has good chemical and mechanical stability, whether a device is single-use or reusable should be determined through risk assessment and validation. For reuse or cleaning cycles, we recommend verifying performance changes through actual testing.
Is this product limited to blood-related applications only?
Not necessarily. Although the PBT membrane was originally developed for blood filtration and medical use, its material properties;such as chemical resistance, thermal stability, and controlled pore structure;also make it suitable for other high-purity or bio-related filtration applications. Applicability should always be confirmed according to the medium and regulatory standards.
How is product cleanliness and safety ensured?
The membrane is produced using medical-grade PBT under controlled manufacturing conditions with strict cleanliness and quality management. For medical or blood-contact use, third-party testing and documentation can be arranged based on specific project needs.
Can this membrane be customized?
Yes. Thickness, pore size, basis weight, and structure can be tailored to achieve the desired balance between filtration performance and mechanical strength. Additional customization options may be evaluated depending on appearance or functional requirements.
What processing and edge-sealing options are available? Can you provide custom sizes?
Supports heat sealing, ultrasonic welding, and multi-layer support configurations. Available in roll, slit, or cut-sheet formats. Representative specs: width 20–35 cm, thickness 0.06–0.2 mm, basis weight 20–100 gsm (all customizable upon request).
What documents, MOQ, and lead time are available? Do you offer batch traceability and third-party reports?
We can provide basic material declarations, batch traceability, and CoA/CoC documentation. Third-party reports such as ISO 10993, extractables/leachables, or endotoxin testing can be arranged upon request. MOQ depends on width, basis weight, and customization level; typical lead time is about 3–5 weeks. NDA, OEM, and ODM cooperation are supported.
