![]() To compensate for this, engineers also consult the tensile modulus (modulus of elasticity), which is the ratio of stress to strain below the yield point of the material. When heat is combined with load, some plastics exhibit creep (a tendency to slowly lengthen, yield and deform), which can make tensile data potentially misleading. The tensile data of plastics is determined in an ideal temperature controlled lab under short-term conditions, whereas real-world operating environments apply loads over time with variable temperatures. Understanding High Tensile Strength Plastics High tensile strength plastics can take the place of metal in many applications, reducing weight and cost without sacrificing performance. Tensile strength is one of the most important and widely measured properties of materials used in structural applications. Some materials will break sharply – called a “brittle failure” – while others experience some deformation before fracture. Tensile strength is the maximum stress a material can withstand without breaking while being pulled or stretched. To understand high tensile strength plastics, we must first discuss tensile strength.
