YAMASHIN Nano Filter™ is a groundbreaking
new material that will improve society.
In 1978, YAMASHIN developed and produced a glass fiber
that is used for in-house filter element production.
This specially-developed technology has made Yamashin a global
top niche filter manufacturer in the construction machinery field.
In 2017, Yamashin developed and succeeded
in the mass production of nanofibers (YAMASHIN Nano Filter™).
With YAMASHIN Nano Filter™,
Yamashin is embarking on a new challenge - to enter into
new fields beyond the filtration business.
Huge Possibilities
YAMASHIN Nano Filter™ presents the possibility of leading
a paradigm shift in the materials sector
that could not previously be solved using conventional materials.
of resin

- Adjustable melting point : 200 ~ 320 °C
- The most suitable resin can be selected
diameter
- Adjustable diameter : 150 nm ~ 10 μm
- The fiber diameter distribution can be selected specifically, as required
properties
- High porosity / high surface area
- High sound absorption, heat insulation,self-extinguishing properties (non-combustibility / flame retardance)
Adjustable to meet customers’ specific requirements
The YAMASHIN Nano Filter™ technology, which is adjustable for a wide range of melting points , allows a large choice and combination of resins.
Moreover, the fiber diameter can be adjusted to values between 150 nm and 10 µm. Resins, when thinned down to the nano level, will have new characteristics, such as high polarity, larger specific-surface area, self-extinguishing (flame retardant) , and heat/sound insulating properties that the materials don’t innately have. Using this technology, it is now possible to meet the customer needs that were not possible using conventional filter media.
Nanofibers are defined as a fibrous form of material having a diameter of 1 nm ~ 1,000nm (1μm).
New physical properties can be obtained by thinning fibers to the nano level. By using this mechanism, Yamashin is currently developing various new raw materials.
Features
YAMASHIN Nano Filter™ can be created using a wide range of
polymers with different properties
YAMASHIN Nano Filter™ can be used to solve problems in application areas that cannot be addressed using conventional methods.
If you have a polymer type that cannot be used for a particular application area, please contact us.
Fiber diameter distribution of 
For example, when using PP (polypropylene) as the raw material, we can produce fiber diameters from 200nm ~ 3μm, with a peak diameter of 600 nm ~ 800 nm.
it is possible to produce diameters smaller than those obtained when using PET as the raw material.
Unique Production Method
The YAMASHIN Nano Filter™ production method
has various advantages over other methods
Comparison (Pros & Cons)
| Pros(+) and Cons(-) | |
|---|---|
| Yamashin’s Melt-blown method | + Various thermoplastic resins can be used + Adjustable diameter (150 nm ~ 10 μm) + Able to create different fiber structures (sheet form, cotton form, etc.) + Easy maintenance + Good productivity |
| Composite Spinning method | + Uniform thickness, varying cross-section + Minimum fiber diameter of 150 nm + Suitable for thin films and medical field use − Large equipment cost (min. 3 billion yen) − Solvent required |
| Electrospinning method (ESD method) |
+ Ultrafine fiber with diameter of several 10 nm (1g/m2) + Heat sensitive substances can be turned into fibers − High introduction cost − Low productivity and low manufacturing safety |
| Ordinary Melt-blown method | + Good productivity − Production of ultrafine fiber diameter impossible − Smallest diameter of roughly 800nm (fine tuning difficult for production of 1 μm or less) |
Applications
