Features of Yamahachi Porous
Yamahachi Porous Plastic has great features for your innovative products
Functional porous plastic with opening pores
Our open cell porous plastic has an abundance of continuous pores in its structure. It is made from polyethylene (PE) with 60-80% of the total material volume of opening micropores in its structure, characterised by flexibility, absorption and chemical resistance. These unique properties make it possible to meet many application needs in a wide range of fields.
We mainly produce our porous plastics by injection moulding and extrusion. However, depending on the shape and customer application requirements, we can also add secondary process such as grinding or other special processing after moulding.
If necessary, our technical engineers can offer additional options according to your needs for your product. Let us challenge you with a new innovation!
Standard Features
| Material ：LDPE | Pore size：5 – 30 μm | Porosity：60 – 80％ | Heat resistance: 50-80°C |
| Flexibility | Flexible and does not damage the surface of workpiece or object |
| Absorption | Easy to penetrate liquids such as oil and ink |
| Venting | Passes air or gas |
| Hydrophobic | Having weak interaction with water, so not absorbing water or moisture |
| Shape range | Standard shapes such as sheets, rolls and tubes by extrusion, and also complex 3D shapes by injection molding |
| Durability | Highly durable (PE) |
| Lint-free | No fiber is used, not easy to create a dust or a lint. |
| Chemical resistance | Highly resistant to acids and alkalis, and relatively resistant to oils and organic solvents |
 |  |  |  |
Options
| Material | HDPE, EVA, PP |
| Hardness adjustment | Can be customized |
