Tear and tensile strength and seam strength; Flame resistance; Anti-static; Stretch and recovery; Soil and stain release. Textiles are also used in the interior of cars, the most obvious uses being for seat covers, safety belts and airbags. [7] Automotive textiles share similarities with home textiles but with stringent quality parameters.
Nylon 11 is seen to have increased dimensional stability in the presence of moisture due to its low concentration of amides. Nylon 11 experiences 0.2-0.5% length variation and 1.9% weight variation after 25 weeks of submersion in water in comparison to 2.2-2.7% elongation variation and 9.5% weight variation for Nylon 6.

Repeating unit of polyphthalamide. Polyphthalamide (aka.PPA, [1] High Performance Polyamide) is a subset of thermoplastic synthetic resins in the polyamide family defined as when 55% or more moles of the carboxylic acid portion of the repeating unit in the polymer chain is composed of a combination of terephthalic (TPA) and isophthalic (IPA) acids.

For equal mass and construction, polypropylene rope is similar in strength to polyester rope. Polypropylene costs less than most other synthetic fibers. Polypropylene is also used as an alternative to polyvinyl chloride (PVC) as insulation for electrical cables for LSZH cable in low-ventilation environments, primarily tunnels. This is because ...
The currently most-consumed engineering plastic is acrylonitrile butadiene styrene (ABS), used for e.g. car bumpers, dashboard trim and Lego bricks. Engineering plastics have gradually replaced traditional engineering materials such as metal, glass or ceramics in many applications. Besides equalling or surpassing them in strength, weight, and ...

The Zytel product range takes advantage of the fact that nylons are one of the most compatible polymers with modifiers and so offers grades with varying degrees of fiberglass, from 13% to 60% (to increase stiffness and strength), rubber toughened resins and flame retarded grades. Nylon resins with mineral reinforcements are branded 'Minlon'. [1]
English: Material comparison plot for Strength versus density. The guidelines for minimum weigth design are added. The strength for each group of materials is: Metal and polymers: Yield Strength; Ceramics: Compresive Strength; Elastomers: Tensile Tear Strength; and; Composites: Tensile Failure.
