Adhesives for filters with enhanced thermal stability

Filter manufacturers can now process their products with adhesives that are even more thermally stable – and save money at the same time. Henkel, the global leader in adhesives, sealants and surface treatments is presenting its innovative adhesives at the World Filtration Congress in Graz, Austria, from April 16 to 20.

High-performance adhesives are indispensable for the production of industrial filters. They fulfill important design functions such as the stabilization and end bonding of folded filter media or the joining of filter media to frame parts. The adhesives used must meet high quality standards, since they will be exposed in use to many different kinds of stresses, resulting from heat, pressure and chemicals. Add to that the demands on manufacturing efficiency: Filters are normally manufactured in large quantities, which requires fast cycling during adhesive dispensing as well as highly economical product usage.

Macroplast UK 1352

The new polyurethane adhesive Macroplast UK 1352 developed by Henkel offers multiple advantages here. A filter bonded with this adhesive can withstand continuous operating temperatures of up to 120 degrees Celsius, double the temperature resistance of the predecessor product. In addition, the innovative adhesives reaches handling strength at room temperature after only 15 minutes.

For filter manufacturers, Macroplast represents a viable alternative to traditional epoxy adhesives. The latter have to be processed hot, are therefore energy-intensive, and take about one hour to cure. Moreover, they also cost more to buy.

Adhesives for potable water filters

Further innovations for the filter sector are the two new Henkel developments Macroplast CR 3529 and Macroplast CR 8605, both of which have been approved for use in potable water filters. These adhesives also have double the temperature resistance of their predecessors – up to 80 degrees Celsius in continuous operation.

Low application amounts and strong bonding

The guiding principle for the adhesives developers at Henkel is always to aim for achieving the required bonding strength with the lowest possible product usage. The various types and uses of filter systems – from automotive and HVAC applications through to medical and water purification technology – make very different demands on the adhesives as well.

Customers will be able talk to Henkel experts at the World Filtration Congress, the global flagship event for the industry. Henkel will be exhibiting its new developments and other adhesives for the filter industry at Stand H12.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa...

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin...

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
