With a Variety of Types and Applications, Filters Play a Crucial Role in Performance, Fuel Efficiency, Machinery Maintenance, and Air Quality in Both Vehicles and Industrial Equipment.
The growing demand and competitiveness in the automotive industry have driven the development of materials and technologies offering superior performance, both in physical properties and functionality. As a result, today, it is possible to manufacture automotive filters with excellent characteristics that meet the requirements of various applications.
Key Polyurethane Technologies for Automotive Filter Production
Expandable PU
Provides anchoring for the filter media, offering low deformation, high resilience, and low Shore hardness. It is ideal for better fitting within the housing due to its uniform expansion, small cells, and flexible elastic modulus.
Adhesive PU
An adhesive material that bonds the base to the filter media, offering excellent adhesion. Commonly used in cabin filters and oil filters, ensuring strong bonding to various metallic or plastic substrates.
Elastomeric PU
Non-expandable, elastomeric polyurethane provides good hardness, structural integrity, and ensures the firmness and sealing of the filter.
Plastisol
Used in various types of filters, including air filters, fuel filters, and sealed oil filters. This material combines high chemical resistance (to alcohol) with low raw material costs.
Two-Component Epoxy – Industrial Filters
Used in filters requiring high-temperature and chemical resistance, such as sealed filters. It is widely applied in the industrial segment.
Types of Automotive Filters and Recommended Polyurethane Formulations
Here are examples of automotive filters and the polyurethane formulations best suited for their production, ensuring superior performance:
| Filter Type | Recommended Polyurethane Technology |
| Air Filters | Expandable PU and Plastisol |
| Cabin Filters | Expandable PU and Adhesive PU |
| Eco Oil Filters | Elastomeric PU |
| Sealed Oil Filters | Adhesive PU, Plastisol, and Two-Component Epoxy Adhesive |
| Fuel Filters | Plastisol |
