Tensioned polyurethane fine screen meshes (sometimes referred to as polyurethane high frequency screen mesh) are made of polyurethane sheet with high density opennings. They enioy a very smooth screen surface to ensure the screening efficiency. They are equipped with hooks which can be polyurethane or metal to tension the whole mesh. There are various customized polyurethane colors, such as red,orange green, yellow, black. | |||||||||
Aperture: 0.063–1.5 mm (customizable)
Screen Size: 1045 × 700 mm, 840 × 1245 mm, 1000 × 2320 mm, 1200 × 2320 mm (customizable)
Material: Polyurethane materials are divided into polyester type and polyether type, with specific parameters as follows:

*Special requirements can be negotiated for customization. |
1.Fine wear resistance and long service life.
2.Easy installation and quick maintenance.
3.Cost-effective.
4.High screening efficiency with moisture-proof performance and freedom from adhesion of wet particles.
5.Anti-corrosion,non-flammable, nontoxic and tasteless.
6.High sieving yield with low block rate.
7.Fine vibration absorption performance with lower noise emission.
8.Good self-cleaning performance, due to the characteristics of the secondary vibration of polyurethane.
