TPEE plastic, also known as thermoplastic polyester elastomer, is a polymer material with excellent physical and chemical properties. Its density and hardness are affected by many factors.
First of all, the density of TPEE plastic is affected by its chemical composition.TPEE is a polymer material copolymerized by polybutadienol ketone and terephthalate, and different chemical compositions will lead to different density of TPEE plastic. Usually, the density of TPEE plastic is between 1.1-1.25g/cm³, while the density of polyethylene is only 0.92g/cm³, and the density of polypropylene is 0.91g/cm³, so the density of TPEE plastic is slightly higher than that of usual plastic.
Secondly, the hardness of TPEE plastic is affected by a combination of factors. One of the main factors is the molecular structure of TPEE plastic. TPEE plastic has a linear, branched or crosslinked and other different molecular structures, different structures will affect the hardness of TPEE plastic. Generally speaking, the more complex the molecular structure, the longer the molecular chain, the higher the degree of crosslinking TPEE plastic hardness.
In addition, the hardness of TPEE plastic is also affected by its processing technology, TPEE plastic can be extruded, injection molding, compression molding and other processes, different processing technology will affect the molecular arrangement of TPEE plastic, the degree of crystallization and other factors, which in turn affect the hardness of TPEE plastic.
In general, the density and hardness of TPEE plastic by its chemical composition, molecular structure, processing technology and other factors. Only on the basis of mastering these influencing factors, to better understand and apply TPEE plastic.
