With liquid seals, adhesives and potting compounds, Rampf offers the material for filter manufacturers. Among the reactive plastic systems based on silicone, polyurethane and epoxy Rampf Production Systems also including the machines for their processing as well as the mixing and dosing technology Automationsolutions in the portfolio.

Liquid and thixotropic sealing foam 

Branded liquid and thixotropic sealing foams PURE Raku are suitable for sealing the air filters in ventilation and air conditioning systems. The polyurethane systems harden quickly and therefore only require short processing times. They also offer good compression set. There is also a liquid seal with antibacterial properties. The antibacterial sealing foam Raku PUR 32-3294-2 has been certified according to the DIN EN ISO 846 standard (11/2020).

For filter elements in Explosive areas Rampf has soft (Shore A 85) and hard (Shore D 80) casting compounds in its range. They have good flowability and can be machine processed. These special casting compounds have a conductivity of 0,03 MOhm/cm and have good chemical resistance.

The compact ones are used to fix the filter elements in the filter frame Two components PURE Raku Casting compounds for use. The polyurethanes are silicone-free, flow well and can be made antibacterial. Because they adhere well to plastic and especially ABS and PS, the connecting bars can be used as a load-bearing element. This increases the stability of the filter elements. The filter medium can be fixed in the frame with filled Raku PUR polyurethane hard foams. This requires high mechanical strength, highly abrasion-resistant surfaces and very good adhesion as well as chemical resistance.

For production of oil and Hydraulic Systemfilter the manufacturer has developed numerous casting compounds and adhesive systems based on polyurethane and epoxy. These adhere well to metal and plastic and offer optimized curing properties and fast process times.

The liquid filters, adhesives and casting compounds used in filter technology can Mixing and dosing systems processed reliably by Rampf. As a rule, filters are manufactured in large quantities, so highly automated and flexible machines are required. Automation is one of Rampf's core competencies.

03.02.2022/XNUMX/XNUMX | the Trox Ltd, developer and manufacturer of systems for the ventilation and air conditioning of rooms, relies on the antibacterial polyurethane systems from Rampf Polymer Solutions for the sealing, potting and bonding of air filters.

Due to the corona virus, the Importance of effective ventilation systems also increased again for schools, offices, restaurants, theaters or exhibition halls. For this purpose, Trox offers a comprehensive and tailor-made portfolio of air conditioning and ventilation technology. 

Rampf Trox filterPascal Pollman, Product Manager Filter Technology at Trox: "When qualifying new materials, we were looking for a supplier who works innovatively, offers high-quality products and with whom we can enter into a partnership in the course of finding such a solution. We found such a supplier in Rampf Polymer Solutions and were able to improve our products as a result.” 

When manufacturing the air filter elements the antibacterial sealing systems and casting compounds made of polyurethane are used. The two-component hard foam Raku PUR is used here to seal the filter elements. With its fast curing time, the seal offers a short process time. The individual filter elements are fixed in the filter frame with the two-component casting compound. The systems offer maximum stability, high mechanical strength and very good adhesion.

For the production of the new air conditioning system X Cube X2 a Raku PUR two-component adhesive is used. The adhesive system connects the individual parts of the sandwich panels, hardens quickly and also has high mechanical strength as well as temperature and chemical resistance. 

When processing the rigid foam to seal the filter elements, the Dosing robot DR-CNC from Rampf Production Systems. With extremely variable XYZ travel strokes and the most modern Control Technology the mixing and dosing system becomes perfect with the maintenance-free CNC linear axes combined. This results in an optimal interaction of motion sequences and dosing process.

The North American subsidiary of the Rampf Group offers contract manufacturing services from two production sites: the headquarters in Wixom, Michigan, and the branch in Suwanee, Georgia. In addition, high-volume contract manufacturing orders are processed directly at the customer's or in one of the company's own plants.

"As a leading developer and manufacturer of mixing and dosing systems as well as 2-component polymer systems based on polyurethane, epoxy and silicone, we know which materials and process technologies can be used to achieve the best results for the specific application. We have numerous high-performance machines that, in addition to top quality, also guarantee high volume flexibility," says Gordon Winters, US Operations Manager at Rampf Group, Inc.

Custom in-situ seals

The provider manufactures customer-specific In situ seals made of polyurethane using FIPG (Formed-In-Place-Gasket) and FIPFG (Formed-in-Place-Foam-Gasket) technology. The sealing foams are applied directly to the customer's component by CNC dosing robots, where they foam up and bond within a very short time. This ensures both a reduction in cycle times and efficient processing. The application-specific polyurethane seals are high-performance sealing systems that withstand high pressure and high temperatures and are very resistant to chemicals.

Antibacterial sealing foam against useless microbes

Rampf sealing foam01.09.2010 | Rampf casting resins has developed the antibacterial sealing foam Raku-Pur 32-3276, which is certified according to VDI 6022. The tear-resistant two-component polyurethane system (PU) reliably seals air conditioning systems, fans, filters, lamps and ventilation systems. The antibacterial sealing foam protects against mould, yeast, bacteria and legionella inconspicuously and efficiently.

The thixotropic material has a very compact, hydrophobic integral skin. It is therefore suitable for sealing complex, three-dimensional components with convex or concave contours. Due to the thixotropy, the foam bead remains constant even on inclines or slopes. The 2K system also impresses with its high tensile strength, low water absorption, quick installation and optimal adhesion to a wide variety of Surfaces - whether painted or powder-coated.

In addition, these seals meet the Hygiene requirements to air conditioning systems (RLT systems) as well as devices VDI 6022 and has been recognized as microbially inert by the Institute for Air Hygiene. The test was carried out in accordance with DIN EN ISO 846. The seals are therefore predestined for use in public areas Buildings such as hospitals or in clean and wet rooms, where useless microbes are absolutely taboo.

Koolair saves 40% in production costs

Koolair sealing foam


The Koolair company also relies on foam sealing. The leading manufacturer for Air Conditioning uses the antibacterial polyurethane sealing foam for all air distribution applications such as ventilation grilles, atomizers and access locks. The foam sealing is done by a low-pressure mixing and dosing system from the sister company Rampf Dosiertechnik.

According to Koolair, the system solution saves up to 40% of production costs. So that's that 2K PU system In the future it will not only be found in hospitals or private homes, but also in spectacular buildings such as the new Convention Center in Dublin, Ireland, or in extravagant hotels such as the Puerta de America in Madrid.
