novapress ® FLEXIBLE/815

Product catalog summary

Material Profile
The novapress® FLEXIBLE/815 is a high-performance gasket material composed of a larger proportion of nitrile butadiene rubber (NBR) combined with aramide fibers. This composition provides the material with superior oil resistance, minimal swelling in oils and fuels, ideal adaptability, and low gas leakage at minimal surface pressure. The identification color is green/natural.

Application Areas
novapress® FLEXIBLE/815 is suitable for use in light flange structures and applications requiring excellent oil resistance. It ensures outstanding tightness even under low surface pressure conditions, making it ideal for gas and water supply, plant engineering, equipment manufacturing, and pipeline construction.

Environmental and Quality Certifications
Frenzelit is certified under ISO/TS 16949 and ISO 14001, ensuring transparency and security for customers. For application inquiries, contact [email protected].

Product Data
Available dimensions are 1000 x 1500 mm, 1500 x 1500 mm, and 3000 x 1500 mm, with thicknesses ranging from 0.3 mm to 4.0 mm. Additional sizes are available upon request.

Material Data
The binder used is NBR, with approvals from DVGW, SVGW, and BAM (up to 75°C/100 bar). The material features a non-standard anti-stick coating and complies with DIN 28 091-1 for sheet size and thickness tolerance.

Physical Properties
Key properties include a density of 1.50 g/cm³, tensile strength of 26 N/mm² longitudinally and 9 N/mm² transversely, and a residual stress of 30 N/mm² at 175°C. The material exhibits compressibility of 10% and recovery of 64% according to ASTM F 36 J.

Fluid Resistance
Under ASTM F 146, the material shows a weight change of 9% and thickness increase of 3% in ASTM IRM 903 at 150°C, and a weight change of 11% and thickness increase of 5% in ASTM Fuel B at 23°C.

Technical Information
The material's deformation under temperature is detailed, with specific leakage rates provided. Recommendations for use are based on pressure and temperature, with higher stresses possible for thinner gaskets.

Warranty Exclusion
Due to varying installation and operation conditions, the information provided is for guidance only and does not form the basis for warranty claims.
