Acrylic heat-resistant dust filter bags manufactured and supplied by Tan Thanh Filtration Company in the Vietnamese market are the top choice for boiler systems, incinerators, detergents, fertilizers…
Acrylic Filter Material
What is Acrylic?
The popular Acrylic material is Acrylic Homo Polymer, which is basically made of 100% Acrylonitrile.
There are two types of Acrylic material with different chemical formulas, Homo Polymer and Co Polymer with Methyl Acrylate. The illustration below shows that Homo Acrylic is significantly better in high temperature (170ºC) and Oxidation (when exposed to air for a long time continuously for 4 hours).
Main features of PPS filter material
Advantages:
- Acrylic bags are classified in the type of high temperature resistant dust filter bags, capable of continuous operation at 120ºC , peak temperature at 150ºC.
- The most outstanding ability of Acrylic material is excellent chemical resistance and hydrolysis resistance is much better than other heat-resistant materials.
- With its hydrolytic feature, Acrylic can be treated with enhanced liquid resistance, to reduce the tendency for dust cake to adhere due to moisture or oil.
- As a synthetic fiber, Acrylic can be combined with anti-static steel fiber to prevent the risk of fire and explosion due to static electricity.
Disadvantages:
- Acrylic fibers are quite sensitive to residual Oxygen concentrations in exhaust gas. At high temperatures, Oxidation reduces the mechanical strength of Acrylic fibers. Therefore, for dust filtration applications with Oxygen concentrations above 10% Vol, Acrylic is not suitable for use.
Scale of heat resistance and chemical conditions of PPS materials in dry conditions
Note: Maximum continuous temperature may need to be reduced based on actual operating conditions, chemical limitations and dry operating range.

Acrylic filter fabric manufacturers
From the excellent properties of Acrylic, typical manufacturers such as Gutsche (Germany) and AOG (Japan – India) have researched and developed exclusive technologies to create different types, with technological characteristics, enhancing the capabilities of conventional Acrylic fibers, capable of matching Zero Emission requirements.
Gutsche’s special technologies applied to Acrylic filter materials:
- Antafin®: Surface treatment has effective anti-adhesion ability against greasy dust and oil. Increases chemical resistance, improves filtration efficiency.
- Createx®: Technology of coating PTFE Membrane on the surface of Acrylic filter material. Increases the life of filter material, increases filtration efficiency for fine dust (PM 2.5), helps dust cake separate from the material surface more easily. Aims for Zero Emission standard.
- Condutex®: Integrates anti-static properties into Acrylic filter material where required.
AOG’s special technologies applied to Acrylic filter materials:
- Fluorobond™: The fluorocarbond treatment imparts liquid repellency to the fabric surface, providing chemical resistance (medium level) and the ability to release dust cake from the fabric surface more easily.
- Twintech™: The surface treatment technology coated with PTFE membrane (ePTFE Membrane) can help retain ultra-fine dust particles on the fabric surface, increase the ability to separate dust from the surface, improve filtration efficiency, and protect the filter material from environmental chemicals.
- Staticguard™: Integrates conductive fibers into the filter media to reduce the potential for static buildup with the company’s Checkstatic™ conductive fiber technology.
- Microbond™: Material processing technology enhances the ability to filter fine dust by changing the filter material’s pore structure, supporting the removal of dust cakes, meeting stricter environmental standards (Zero Emission).
Quality testing organizations, setting standards for filter materials:
There are many organizations that can test the quality of Acrylic filter material, the leading ones are:
- ISO – The International Organization for Standardization
- DIN – Deutsches Institut für Normung
- VDI – Verein Deutscher Ingenieure
- FDA – Food and Drug Administration
Tan Thanh Acrylic heat-resistant dust filter bag (TATA Filter)
Production and supply capacity of TAN THANH Acrylic dust filter bags
With more than 13 years of experience in manufacturing various types of dust filter bags, Tan Thanh human resources staff (TATA Filter) have been trained thoroughly from GUTSCHE and AOG experts, understood the techniques and produced high quality Acrylic filter bags for chemical and precious metal factories,..
With modern and automatic machinery lines, we create Acrylic dust filter bags of high and consistent quality. The entire production process applies ISO 9001–2015 quality management standards.
Along with that, we continuously improve product quality, applyingt he technology of adhesive coating which is considered a new innovation of TAN THANH, applied to all types of boiler and incinerator filter bags, to minimize the risk of fine dust escaping into the environment, meeting the most strict environmental protection standard.
Structure of Acrylic Dust Filter Bag
Tan Thanh produce based on the customer’s dimensions requirements. Before production, the technician will survey, measure and take samples, ensuring that the filter bag after installation fits properly and does not leak dust.
- Bag body: Covered with glue to prevent fine dust from passing through and increase the bag’s lifespan.
- Bag mouth: Elastic steel ring is the most common type – Stainless steel (SUS 304).
- Bottom of the bag: Reinforced with two layers of both the foot and bottom of the bag.
- Sewing thread: 100% high strength PTFE.
- Bag dimension: Common with diameter D135 – 165 (mm), length from 1,000 – 7,000 (mm).
