- Product Highlights
Fabrics are made of nylon (PA66), one of the toughest and most durable man-made polymers, creating products with high tensile and tear strength even at low fabric weights.
The thermal stability of nylon is outstanding. Chemical resistance is outstanding, as these fabrics effectively resist attack from many solvents, alkalis, and acids. 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. These are made with continuous filaments and can utilize various filament geometries, bonding technologies, and polymer additives to achieve the desired performance in your application.- Features

Technical Details & Test Data
- 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.
- 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: ISO 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)
- 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 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.
- 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.
