Frenzelit NovaForm 2300 (also often referred to as novapress® 850 / novaform® 2300) is a non-metallic flat gasket sheet material manufactured by Frenzelit GmbH, a German specialist in technical gasket materials and industrial sealing solutions.
General
Description
NovaForm 2300 is a highly adaptable non-metallic gasket sheet that combines the characteristics of fiber-based gasket materials and elastomers (synthetic rubber). It is specifically designed to:
- Adapt easily to uneven flange surfaces or non-uniform surface pressure
- Provide good mechanical stability
- Maintain low leakage rates, even at low surface pressures
- Suit a wide range of industrial sealing applications requiring reliable performance
Material
& Structure
- Made from a blend of high-quality aramid fibers with functional fillers
- Bonded with NBR (nitrile butadiene rubber) to enhance elasticity and resistance to various media
- Asbestos-free material
Typical
Technical Properties
(Values depend on thickness; example given for 2 mm thickness)
- Operating temperature: up to approx. +130 °C (depending on operating conditions and pressure)
- Density: approx. 1.35 g/cm³ (at 2 mm)
- Good pressure resistance, compressibility, and low leakage behavior
- Available in various thicknesses, typically from 0.5 mm up to 3 mm or more
Applications
/ Typical Uses
NovaForm 2300 is commonly used as a gasket or sealing sheet in many industrial applications, such as:
- Covers or housings for gearboxes, pumps, and machinery components with uneven or deformable surfaces
- Systems with large bolt spacing, where uniform surface pressure is difficult to achieve
- Water and gas industries, supported by multiple certifications
- Applications requiring resistance to media such as oil, gas, potable water, and industrial fluids
Certifications
& Compliance
NovaForm 2300 holds several important approvals for industrial and regulated applications, including:
- DVGW (German gas and water approval)
- FDA (for certain food-contact applications)
- EC 1935/2004 (food contact compliance)
- WRAS (UK water regulations)
- KTW / W270 for potable water applications
- TA Luft, VDI 2200 blow-out tests, and others depending on the specific grade
Summary
NovaForm 2300 is a high-performance, flexible gasket material that combines the elasticity of rubber with the strength of fibers. It is particularly suitable for sealing flanges and components with non-ideal surfaces or uneven loading conditions, and is widely used in machinery, pumps, gas, water, and food-related industries.
