Difference Between PVC and TPU


As a professional  leading polymer compound manufacturing company, we would like to share with you the topic difference between PVC and TPU. First we would give a general introduction to TPU. Then we would compare the two from the aspect of material, that is, pvc vs tpu material.


1. What is TPU 

TPU is a mature environmental protection material with excellent characteristics of high tension, strong toughness and aging resistance. At present, TPU has been widely used in medical treatment, electronics, industry, and sports. It has the characteristics of high strength, good toughness, wear resistance, cold resistance, oil resistance, water resistance, aging resistance and climate resistance unmatched by other plastic materials. At the same time, it has many excellent functions such as TPU for Mining cable, high water resistance, moisture permeability, wind resistance, cold resistance, antibacterial, mildew resistance, heat preservation, UV resistance and energy release. TPU can be divided into the polyester type and polyether type according to the molecular structure, and can be divided into injection molding, extrusion and blow molding according to the processing mode.


2. TPU material vs PVC

Different uses of TPU material vs PVC

TPU: It is widely used in tpe cable jacket, daily necessities, sporting goods, toys, decorative materials and other fields

PVC: It can be used to make anti-corrosion pipelines, pipe fittings, oil pipelines, centrifugal pumps and blowers. PVC hard board is widely used in the chemical industry to make the lining of various storage tanks, corrugated boards of buildings, door and window structures, wall decorations and other building materials.

Different characteristics of TPU material vs PVC

TPU: TPU is a mature environmental protection material with excellent high tension, toughness and aging resistance. It has the characteristics of high strength, good toughness, wear resistance, cold resistance, oil resistance, water resistance, aging resistance and climate resistance unmatched by other plastic materials. At the same time, it has many excellent functions, such as high water resistance, wind resistance, cold resistance, antibacterial, mildew resistance, heat preservation, UV resistance and energy release.

PVC: PVC has good electrical insulation performance and chemical stability, and can be used as low-frequency insulation material. Due to the poor thermal stability of PVC, heating for a long time will lead to its decomposition, thus releasing HCl gas and discoloring PVC. Therefore, its application range is narrow, and the service temperature is generally between - 15 ~ 55 ℃.

TPU: tpu compound is a high molecular material formed by the reaction and polymerization of diisocyanate molecules such as diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) with macromolecular polyols and low molecular Polyols (chain extender).

PVC: PVC material is one of the largest plastic products in the world. It is cheap and widely used. PVC resin is a white or light yellow powder, which can not be used alone and must be modified.
