TPEE Membrane
AF-5100

TPEE membrane is a high-performance moisture-permeable and breathable material. It is made using a melt-blown process and the base material is polyester elastomer (TPEE). It has excellent membrane properties and moisture permeability and is widely evaluated in medical, health, clothing and etc.

What is Thermal Bonding of Meltblown Nonwoven?

Thermal bonding applies heat + pressure + short dwell time to locally melt fiber intersections, which then cool and solidify into stable bonds, achieving seamless adhesion without glue.

  • What it does: Binds fine fibers in dots or grids, improving dimensional stability, abrasion resistance, and interlayer strength.
  • Why it matters: Using embossed point bonding keeps pores open, balancing airflow/filtration resistance with strength.
  • How to control: Balance temperature, line pressure, and dwell time; too high causes stiffness/collapse, too low leads to weak bonding.

Key Features

  • Breathable & Moisture-permeable: TPEE base material combined with melt-blown technology creates a microporous structure, providing excellent breathability and moisture permeability for sweat wicking and dryness.
  • Elastic & Comfortable: Soft with high elasticity, conforms to body curves, offering comfort while minimizing friction and irritation.
  • Durable & Tear-resistant: Specially treated surface with strong abrasion and tear resistance, suitable for extreme environments.

Applications

  • Medical Use: Widely used in medical dressings, surgical gowns, and masks, combining comfort with breathability.
  • Hygiene Products: Suitable for sanitary napkins, adult diapers, and similar products, offering long-lasting dryness.
  • Apparel Materials: Applied in sportswear and functional clothing for enhanced breathability and comfort.

Test Results

  • Air Permeability: > 5000 g/m²/24h
  • Moisture Permeability: > 5000 g/m²/24h
  • Heat Resistance: -40℃ ~ 120℃

Manufacturing Process

  • Utilizes melt-blown technology, where TPEE is melted and extruded through special nozzles to form a uniform microporous structure.
