Description

Polyester filter media is the most versatile, most cost-effective and most widely used filter media for dust collection. Polyester filter media is strong, abrasion resistant can work up to 150°C and has good resistance to common acids, solvents and oxidizing agents

A wide variety of chemical and thermal treatments are available for polyester filter media, the most common being super glaze to improve dust release and liquid repellency waterproof to assist with sticky dusts.

ACIDS – GOOD

ALKALIS – FAIR

OXIDIZING AGENTS – GOOD

HYDROLYSIS – POOR

SOLVENTS – GOOD

MAXIMUM CONTINUOUS IN DRY CONDITIONS: 150°C / 302°F

Tianyu unit of filter media manufacturing has distribution centers with assorted stocks for ready delivery distributed in China, North America; Brazil and Europe and so on.

Filter media are designed for the manufacture of bags and Sleeves and undergo treatments according to the type of application. 

Tianyui  posses the experience and the capacities to realize even non-standard customer wishes at short notice. 

Finishing :heat set

When fibers are manufactured they invariably have a residual tendency to shrink in length when heated substantially. After these raw materials are converted to filter felts, they need to be heat stabilized to ensure that any shrinkage in the final application is minimized.

There are a number of ways of achieving this, but in essence, all require that the product is exposed to a temperature comfortably above the expected operating temperature. The material has then has to be held at that temperature to ensure that the in-built stresses are relaxed out.

The result is a stabilized fabric which will exhibit minimal shrinkage at the anticipated operating temperature

Finishing Oil and Water Repellent

It is applied by total immersion in a bath followed by drying and curing. This guarantees that every individual fiber in the felt is covered in a sheath of chemical which ensures very high and consistent levels of repellency. The treatment is available for application to almost the entire range of filter media and can frequently be used in conjunction with other product modifications.
