As an exclusive distributor of Frenzelit GmbH products in Italy, we offer a wide variety of gaskets made of soft materials: high-quality fiber gaskets, graphite gaskets, high-temperature mica gaskets and PTFE gaskets. Furthermore, our offerings include gaskets with silk-screen printing, metal gaskets and textile gasket solutions.
Analysis and design
Our technical department is at your disposal to analyse the behaviour of the gaskets under operating conditions.
All elements of the sealing system, such as the shape and roughness of the flange surfaces, pressure, temperature, types of fluids, etc., must be analyzed to ensure successful gasket installation.
We perform tightening tests using special sensitive films (Fuji Prescale) and analysis software that allow us to detect the pressure level exerted over the entirety of the gasket’s contact area.
We use the information collected from our customers to conduct tests and trials. We suggest customized solutions to our customers, with no size, shape, or quantity constraints.
Our multi-head water-jet cutting machines guarantee fast and flexible prototyping, together with high efficiency in the production of small and medium product series.
Block dies, progressive dies, and dedicated blanking lines ensure high productivity in the production of large batches.
Choosing the most suitable material for each application means evaluating various factors, including the fluid to be retained, the temperature, and the internal pressure.
Frenzelit diversified materials possess special properties that are well suited to:
- Low surface pressure;
- Temperature increases and clamping load variations;
- Bolted flanges subjected to high temperatures and torsional loads during installation.
Elastomer-bonded fiber gaskets
The novapress® product family represents the latest technology in fiber-based gasket sheets.
novapress® is a group of elastomer-bonded gasket materials based on high-quality aramid fibers and special functional fillers.
novapress® products are the standard in flat gasket applications and cover nearly all conventional applications; however, each product has special properties that make it ideal for use in specific applications.
Fiber-reinforced graphite gaskets
novatec® brings two worlds together: The world of conventional fiber gaskets and the world of graphite gaskets.
Their very high graphite content makes novatec® gaskets superior to conventional fiber gaskets due to the following properties:
- Higher temperature resistance
- Better chemical resistance
novatec® is ideal for more stringent requirements that conventional fiber gaskets cannot meet or no longer reliably satisfy. Thanks to their material structure, novatec® products have sufficient inherent strength to make a metal insert unnecessary for reinforcement. This makes them suitable for use with a variety of media.
The novaphit® product family comprises a range of high-quality expanded graphite flat gasket materials.
novaphit® gaskets are reliable and durable even at the outer application limits, which makes them the perfect choice wherever excellent efficiency and performance paired with maximum process reliability are required.
novaphit® gaskets have the following properties:
- Temperature range from -200°C to 550°C
- Universal chemical resistance
- Excellent adaptability to flange unevenness
- Insensitive to changing loads
The novaflon® product line is based on modified or expanded PTFE. This material makes the gaskets resistant to most acids and alkalis throughout the entire pH range from 0 to 14. novaflon® gaskets can therefore be used universally with nearly all media and are perfect for use in the chemical industry.
Moreover, novaflon® complies with Regulation (EC) No. 1935/2004 and meets the strict requirements of FDA guidelines. This means that novaflon® can be used in both food production and the pharmaceutical industry.
All members of the novaflon® family meet the TA Luft (German Technical Instructions on Air Quality Control) criteria [leakage rate < 10-4 mbar·l/(s·m)].
novaflon® can be used at a wide range of temperatures, from -210 °C to +260 °C, and has an unlimited shelf life when stored in compliance with the storage conditions recommended pursuant to ISO 2230.
novaflon® gaskets offer a number of key advantages over pure (virgin) PTFE produced using conventional methods:
- Resistant to high pressure and temperature loads
- High residual stress
- Good mechanical strength (even under temperature stress)
- Blow-out resistant according to VDI directive 2200
Phlogopite mica gaskets
The novamica® product family is based on high-grade, optimized phlogopite mica, which is far superior to other types of mica in terms of temperature resistance. In combination with an effective binder system, novamica® opens up a variety of application possibilities in high temperature ranges. novamica® materials have excellent performance characteristics thanks to their extremely low binder content.
novamica® enables reliable solutions for applications that cannot be met by conventional gasket materials.
novamica® gaskets have the following properties:
- Extreme temperature resistance up to 1000 °C.
- High chemical resistance – even against aggressive and corrosive media.
- Good thermal and electrical insulation properties.
- Incombustible (DNI = does not ignite – according to the ASTM SAE J369 fire test).
- Good adaptability to flange unevenness.
- Reliable long-term performance even at maximum temperatures.
- Extremely low binder content guarantees long-term stability.
novamica® products are not only suitable as conventional high-temperature gaskets but also as insulation materials or temperature-resistant compensation elements.
novamica® materials are best suited for applications with a temperature level of 400°C or higher.
Industrial exhaust gaskets
novaform® EXHAUST GASKETS are specifically designed for exhaust applications with increased thermal and mechanical loads on gaskets, for example in diesel engines, turbo chargers, compressors, exhaust systems, etc
