Thermoplastic polyurethane (TPU) is any of a class of polyurethane plastics with many properties, including elasticity, transparency, and resistance to oil, grease, and abrasion. Technically, they are thermoplastic elastomers consisting of linear segmented block copolymers composed of hard and soft segments.
Used in high-performance applications such as sports shoes, electronic device components, automotive fuel lines, pneumatic airbrake tubing, oil and gas flexible pipes and control fluid umbilicals, and catheters. Technora: Copolyamid: High tensile strength, resistance to corrosion, heat, chemicals and saltwater
Polyetherimide (PEI), produced by a novel nitro displacement reaction involving bisphenol A, 4, 4’-methylenedianiline and 3-nitrophthalic anhydride, has high heat distortion temperature, tensile strength and modulus. They are generally used in high performance electrical and electronic parts, microwave appliances, and under-the-hood ...
The ASA mixtures have excellent rutting resistance and moisture damage resistance. The tensile strength ratio of the ASA and asphalt mixture are all larger than 0.8 and therefore satisfy the Superpave specification. The average coefficient of permeability of the ASA mixture is 6–10 times higher than the asphalt mixture in the same air void level.
7068-T6511 has typical ultimate tensile strength of 710 MPa (103 ksi) versus a similar product produced from 7075-T6511 that would have a typical ultimate tensile strength of 640 MPa (93 ksi). Typical yield strength for alloy 7068-T6511 is 683 MPa (99.1 ksi) versus 590 MPa (86 ksi) for a similar product produced from 7075-T6511. [2]
The ultimate tensile strength of a material is an intensive property; therefore its value does not depend on the size of the test specimen.However, depending on the material, it may be dependent on other factors, such as the preparation of the specimen, the presence or otherwise of surface defects, and the temperature of the test environment and material.
Tensile strength: Usually between 5 and 20 MPa, varying by specific blend and processing conditions. [8] Elongation at break: Stretchable up to 3 times its length (300%). [8] Compression set: The range is 10 to 30%, reflecting a major recovery after deformation. [8]
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]
