- Hydrocarbon Resistance
Nylon’s amide groups help protect the aliphatic carbonyl chains from solvent attack.
- Alcohols like methanol and ethanol (unleaded gasoline) and Propylene Glycol (hydraulic fluids) attack PET.
- Additives used for flame retardants, lubricity aids, and freeze protection compounds can also attack PET.
- Advantages
- One of the toughest and most durable man-made polymers
- High tensile and tear strength even at low fabric weights
- Extreme thermal stability and high melting points
- Resistant to most chemicals, solvents, alkalis, and acids
- Excellence in uniformity and high quality applications
- Features
- Cerex fabrics exhibit excellent uniformity and work well in applications that demand high quality. In addition, nylon bonds well with adhesive and resin systems, making our fabrics excellent components for laminate and composite systems.
- Cerex materials are made with continuous filaments and can utilize various filament geometries, bondingtechnologies, and polymer additives to achieve the desired performance in your application.

- Applications
- Airbag dust covers are designed for the protection of the airbag system once folded and placed into a module. With a predetermined breaking point, the function of the airbag sleeve guarantees your safety 100%. For more than 15 years, CEREX has supplied this market segment and is established as one of the leading manufacturers of airbag protective cover fabrics for frontal, head and side airbag systems. With the evolution of different airbag hanger systems, CEREX products provide the strongest nonwoven materials that can found, meaning you can lower overall weight, reduce noise levels and still have the dependability of nylon. Can also be used as structural reinforcement in airbag systems to add strength at critical points during deployment. Use as a fabric or consider lamination as a solution in your composite.
- From headliner system to package trays, from trunk liners to load floor pans, interior composites play an important role in today’s automobiles. Make sure nylon is part of your design. Pound-for-pound stronger than steel, our nylon nonwovens allow you to add strength and other functionality to your composite while decreasing weight. Use lightweight nonwovens as barriers to resin migration and for improved mold release. Also include our materials as structural reinforcement and drop the overall weight of the composite. Incorporate these fabrics where quietness is a factor or where abrasion resistance is critical. CEREX even offers products for deep-draw applications where other nonwovens fail. Where esthetics are important, our full line of custom colors allow you to mask areas with our low visibility color- keyed (LVCK) backing materials.

Technical Details & Test Data
- Long Term Thermal Stability
Thermal degradation must be considered in any automotive design application.
- PA66 shows only 20% loss after 1800 hours of exposure
- PP shows complete loss after only 400 hours of exposure
PA66 Nylon polymer formulations contain no added stabilizers and exhibit natural long term heat stability.
Polypropylene must utilize thermal stabilizer additives designed to interrupt the chain break reaction but are consumed during heat exposure.- Phenol type stabilizers break down suddenly and produce odors
- Hindered amine stabilizers will react more slowly but still suffer the same ultimate fate
Strength Comparison: IS0 2578 at 120°C
- Thinner Profile Than PET
Allows designs to be
- Smaller,
- More cost effective, and Lighter weight without sacrificing performance or strength.
- Excellent Temperature Resistance
Melting Point (°C)
Nylon 6,6 melts at 265oC which is 24% higher than the Co-PET bonding polymer used in most PET spunbonds..
- It also has a 30% higher heat capacity (1.47 J/g*K) than Polyester.
- Nylon 6,6 absorbs more energy and does not deform as easily as other polymers even at elevated temperatures.
Temperature of Deflection at 66 psi (°C)
- Superior Strength
As a base plastic, the tensile strength of nylon 6,6 is more than double polypropylene and 7% greater than polyester.
- Co-polyesters that are used in many spunbond products have an even lower tensile strength.
Izod Impact Strength (kJ/m)
- Nylon 6,6’s izod impact strength is more than double polypropylene and more than 5 times greater than polyester.
- Greater Tensile Strength Vs. PET
- In fabric form, the strength differential becomes even higher.
- High strength means that you can use a lower weight material in your designs, offering the opportunity to lower weight in the vehicle
- Thin profiles allow designers to integrate these fabrics into composite design for reinforcement allowing removal of other heavier components
- Superior Burst Strength Vs. PET
- Able to withstand high pressure applications including difficult processing and system pulsations
- Improves durability and service life
- Offers lower basis weight options that can reduce weight, cost and waste.
