in what aspects does tpu film have better performance?

tpu filmit is an environmentally friendly material with excellent tensile strength, toughness and aging resistance. at present,TPUthin films have been widely used in medical, electronic and electrical industries, etc. the following is a detailed introduction to the products produced by tpu film manufacturers.tpu filmsuperior performance

tpu film has excellent performance and the molding process is simple and convenient. not only can it be plasticized, mixed and vulcanized like ordinary rubber, it can also be cast, centrifugally cast or sprayed like liquid rubber. it can also be made into granular materials by injection, extrusion and calendering. , blow molding and other processes.

combined with its excellent tension, tension, toughness and anti-aging properties, it can be widely used in shoemaking and medical fields.

however, good and bad are interdependent and contradictory. even if a product is perfect, it still has imperfections. the high temperature resistance, chemical resistance and dependence on raw material imports of tpu films have become three aspects that must be paid attention to.

in terms of performance,tpu filmthe manufacturer recommends paying attention to two aspects.

the first is the chemical resistance of the tpu film.

tpu film is not resistant to strong polar solvents and strong acid and alkali media. alcohols, acids and ketones can cause polyurethane elastomers to expand and degrade under certain temperatures. solvents such as methylene chloride and trichlorethylene will cause tpu to expand at room temperature.

2. high temperature resistant tpu film

the tpu film's elasticity and toughness will not change even at low temperatures of minus 30 degrees celsius, but it can withstand high temperatures. tpu has high internal heat and general high temperature resistance. the normal operating temperature range is -30℃~80℃. therefore, tpu film cannot be used for a long time above 120℃.

the third thing to note is that the current domestic tpu film market is dependent on the externality of tpu raw materials.
