VENSOZ® - SF
Keeps your body DRY & WARM
DEVELOPED ST-PU PELLET BY OUR OWN ⇒
MAKING VENSOZ SF EXCLUSIVELY！
After years of hard work, our team has developed a solvent-free, non-fluorinated functional waterproof and breathable PU film, "VENSOZ® - SF," which addresses existing environmental concerns in the waterproof and breathable film market! Unlike conventional waterproof and breathable PU films that require solvents, "VENSOZ® - SF" is manufactured using a special process and proprietary functional materials developed in-house, eliminating the need for solvents altogether. This enables us to achieve the required functionality while avoiding excessive impact on the environment!

After years of hard work, our team has developed a revolutionary solution that isa solvent-free, less CO2 emissions PU membrane!
We have developed pellets called "ST-PU" that can be used in the same production process as TPU film, leveraging the knowledge of high-performance waterproof and breathable PU film resin from Japan and taking advantage of its superior physical properties.
Features:
- Compared to conventional waterproof and breathable films, both the raw materials and production are more environmentally friendly.
- Excellent heat resistance allows for processing with seam tapes similar to general PU films.
- Outstanding breathability and washability.
- Reasonable price.
- CO2 emissions are reduced by approximately 2/3 compared to conventional PU films.
- This is mainly due to the elimination of the long drying process during production.

Market situation
CO2 EMISSIONS/PFAS/SOLVENT
The issue of carbon dioxide emissions is consistently one of the most critical concerns in the field of environmental protection. Our products achieve higher production efficiency by optimizing materials and manufacturing methods compared to conventional waterproof breathable films, thereby avoiding excessive energy consumption. Additionally, our products are free from environmentally harmful chemicals such as PFAS and solvents. Compared to solvent-based polyurethane films, our products reduce carbon dioxide emissions by approximately 75%. Compared to water-based polyurethane films, they reduce carbon dioxide emissions by approximately 80%. (Please note that this data is based on testing results from our laboratory and does not represent guaranteed values).
75% Less CO2 emission than Solvent-based PU MEMBRANE.
80% Less CO2 emission than Water-based PU MEMBRANE.

Low heat resistance
Typically, TPU has heat resistance up to about 90-120 degrees Celsius, but VENSOZ® - SF can withstand temperatures of approximately 140 degrees Celsius.
This allows VENSOZ® - SF to have an advantage over TPU in high-temperature processing, especially in applications such as seam tape and lamination, where the range of applications is significantly expanded.

Swelling issue
The importance of water repellency in the waterproof performance of functional textiles has shifted primarily from conventional fluorine types to fluorine-free types due to environmental concerns.
As a result of this processing change, the water repellency of fabrics has decreased significantly, leading to a pronounced swelling phenomenon in the moisture transfer mechanism of non-porous waterproof breathable films. Therefore, reducing the swelling value has become one of the important challenges for functional improvement.
| Resin | Description | Moisture permeability performance [g/m² · 24hr] *JIS L 1099B-1 |
Swelling data |
|---|---|---|---|
| Vensoz SF | Item VENSOZ® - SF | 50,000 | 4% ✔ |
| TPU | Normal high MVP type TPU | 50,000 | 14% |
| PU | Solvent based polyurethane membranes | 100,000 | 16% |
Swelling tests involve immersing the test specimen in water and confirming the difference in elongation rate compared to before treatment. Please refer to the table below. The normal expansion rate of moisture-permeable TPU/PU is approximately 14% to 16%, while the expansion rate of VENSOZ® - SF has been significantly improved to about 4%.
The data provided is not guaranteed; it represents the actual testing results from our lab.
As mentioned earlier, by eliminating solvents in the manufacturing process, we have reduced carbon dioxide emissions and avoided the use of harmful raw materials such as fluorine.
The VENSOZ® - SF film comes in two thicknesses: L and H. The H variant offers excellent waterproofing, while the L variant provides excellent breathability, both maintaining excellent breathability and low swelling effects.
Of course, both specifications also have a waterproof pressure resistance exceeding 15k and are suitable for seam sealing at high temperatures.
