## Key takeaways

- Kae Hwa's spec-driven manufacturing process calibrates every physical and functional parameter to a customer's exact requirements using Casting Film Technology.
- Physical dimensions — roll width, length, and thickness tolerance — can be held within ±0.01 mm, while tensile strength, elongation, and hydrostatic resistance are tuned to medical or industrial PPE standards.
- Breathability itself is fine-tuned by adjusting the microporous structure of MicroBreath films or the hydrophilic chemistry of monolithic films, so dimensions, mechanical properties, and MVTR can all be adjusted independently.

## Frequently asked questions

### Can the dimensions, properties, and breathability levels be customized?

Yes. Kae Hwa's spec-driven manufacturing process lets it calibrate every physical and functional parameter to a customer's exact requirements: roll width, length, and thickness tolerance held within plus or minus 0.01 mm, tensile strength, elongation, and hydrostatic resistance tuned to medical or industrial PPE standards, and breathability fine-tuned by adjusting the microporous structure of MicroBreath or the hydrophilic chemistry of monolithic films. This precision casting film technology means dimensions, mechanical properties, and MVTR can all be adjusted independently to match a specific application.

### What physical dimensions can be customized on a per-order basis?

Kae Hwa's Casting Film Technology supports customizable roll width and length, plus a thickness tolerance held within ±0.01 mm, so buyers can specify dimensions precisely rather than choosing from fixed standard sizes.
