## Key takeaways

- As a fully integrated OEM/ODM manufacturer, Kae Hwa can fine-tune WVTR and hydrostatic resistance by adjusting the microporous or monolithic film formulation for each product's climate and use case.
- Beyond breathability, the team offers custom 4-color printing and surface embossing for brand identity and grip.
- In-line solvent-free lamination onto substrates like nonwovens, nylon, polyester, or stretch textiles produces a ready-to-use composite tailored to any regional market.

## Frequently asked questions

### Can specifications, dimensions, colors, and breathability (WVTR) levels be customized for specific regional markets or climates?

Yes. As a fully integrated OEM/ODM manufacturer, Kae Hwa can fine-tune WVTR and hydrostatic resistance by adjusting the microporous or monolithic film formulation, so a humid-climate medical gown and a winter outdoor jacket can each get the vapor permeability level they need. Beyond breathability, the team also offers custom 4-color printing and surface embossing for brand identity and grip, plus in-line solvent-free lamination onto substrates like nonwovens, nylon, polyester, or stretch textiles to produce a ready-to-use composite tailored to any regional market.

### Why would a medical gown and an outdoor jacket need different WVTR levels?

A medical gown used in a humid tropical climate needs a different Moisture Vapor Transmission Rate than a winter outdoor jacket, because the two face different heat, humidity, and liquid-exposure conditions. Kae Hwa's engineering team fine-tunes the microporous or monolithic film formulation for each product's specific climate and use case rather than using one fixed spec.
