For most of medium we can use stainless steel mesh, such as petroleum, chemical industry, mine,airspace, paper-making, electronic metallurgy etc. And for filtering under the acid and alkali environment, the stainless steel 316 material is the best choice as it has very perfect performance on anti-acid and alkali.

For tea filtering, electronic products filtering , dust filtering and other liquid filtering which not need very high precision filter, polyester mesh is better choice as it is much cheaper than stainless steel mesh.

For medium which require high wear-resistant, Nylon6 mesh and stainless steel mesh are the best choice, and stainless steel mesh has better performance than Nylon6.

For foods filtering, it is better to use Nylon66 and stainless steel material. But stainless steel material price is higher than Nylon66 material, you could select the best material according to your actual demand.
