Functions and Applications of Yamahachi Porous Plastic
Unique functions and applications for your innovative products
Applicator & Absorption material
Yamahachi Porous, open cell porous material, which is made mainly from plastic, has the ability to absorb and retain liquids such as oil and ink. It has the function of applying the absorbed liquid to the objects.
Unlike regular felt, it is hydrophobic and does not absorb water and generates low dust. So the use of the material is expanding being used in fields other than Consumer goods, such as porous material of lubricating for mechanical equipment with oil.
Yamahachi propose porous materials suitable for each customer’s product and development.
Features
| Absorption and Reservoir | This material absorbs and reserves oil and ink. |
| Application amount control | This material can apply an appropriate amount to the target object without dripping liquid |
| Small amount application | Pore size control and designing special porous structure allow controlling small amount application |
| Application lifetime | Special porous structure gives longer lifetime of liquid application |
| Rust prevention | Hydrophobic property that repels water and does not blend in (rust prevention effect) |
| Shape range | Rolls, Sheets, Nibs. 3D shapes including complex shapes by injection molding |
| Hardness (option) | Hardness can be adjusted by selecting base material, etc. |
| Hydrophilization (option) | Possible to change to hydrophilic |
Applications
| ■ Industrial | ■ Consumer goods |
| ・Porous material for lubricating oil coating built in mechanical equipment such as linear guides ・Porous material for marking devices ・Oil applicator material | ・Nibs for markers / writing instruments ・Porous material for Hair oil applicator ・Porous tips for Eyeliner |
Pattern marking & pattern imprint material
Text, photo images and patterns even small dots can be processed on the surface of our porous material. After absorbing liquids such as oil and ink, the processed patterns will be transferred with the liquid onto surface of the objects.
Dot pattern processing offers the purpose like applying small amounts of liquid like lubricating oil onto the surface.
Features
| Range of processing image | Text, designs, halftone dots, photographs can be processed clearly |
| Reservoir & imprint function | It absorbs and reserves oil and ink, and transfers and applies the appropriate amount to the target object |
| Longer lifetime | Special pore structure design allows to adjust the number of applications (lifetime) |
| Marking to non-planar objects | Clear marking even on non-planar surfaces by adjusting the hardness and shape of the material |
| Shape range | Roll and Sheet |
| Hardness (option) | Hardness can be adjusted by selecting base material, etc. |
| Hydrophilization (option) | Possible to change to hydrophilic |
Applications
| ■ Industrial | ■ Consumer goods |
| ・Pattern transfer of Oil ・Pattern marking and imprint of ink ・Small amount application function by dot pattern processing | ・Stamp material ・Applicator for cosmetic |
Partial process (Partial flow function of air, ink and oil)
Basic performance of Yamahachi porous is to allow air, gas, ink and oil to pass through, but partial functions can be added by processing the surface of the material.
If the surface of the material is processed, the processed parts becomes a layer that does not allow ventilation or liquid to pass through (B). And unprocessed parts remains a porous structure (C) which allows ventilation or liquid to pass through.
Inner layer remains as open cell porous structure (A) allowing ventilation and liquid to pass through. It is possible to process entire surface and/or partially on any part of the surface.
Features
| Process over entire surface | Two-layer structure with a thin surface layer that does not allow ventilation or liquid passage, and an open cell porous inner layer. |
| Process on partial surface | By processing partially on the surface, the processed surface layer that does not allow ventilation or liquid passage partially. Unprocessed parts remains allowing ventilation and liquid to pass through. |
| Reservoir & imprint function | The unprocessed area transfers and applies ink and/or oil to the target object |
| Shape range | Roll and Sheet |
| Hardness (option) | Hardness can be adjusted by selecting base material, etc. |
| Hydrophilization (option) | Possible to change to hydrophilic |
Applications
| ■ Industrial | |
| ・Special filter ・Special foam pad for acoustic vents of acoustic instruments ・Porous material for partial ventilation/partial liquid passage |
