Questions & Answers
Polyethylene terephthalate rods are made from: PET PBT blend, PET Oil Filled, PET MoS₂, PET PTFE, PET GF30, PET GF, PET-C / CPET, PET-G, PET, PETP.
EN 15860:2018 - Requirements and test methods for thermoplastic semi-finished products for machining. This standard covers marking, porosity, thermal and mechanical properties, dimensional tolerances, appearance, geometry, and material. It covers the following characteristics: surface quality, mechanical properties, dimensional stability, internal defects, curvature, ovality, and core diameter.
ISO 527 - standard specifies methods for determining the mechanical properties of plastics under uniaxial tension. It is used to determine the tensile behavior of the material, strain at maximum load, elastic modulus, elongation, yield strength, and tensile strength.
ISO 178 - standard specifies a method for determining the mechanical properties of plastics under static bending. This standard is used to determine the behavior of the material under bending load, stress at a given strain, bending strain, elastic modulus, and flexural strength.
