a brief analysis of the accuracy of thin film thickness

currently, the world’s mass-producedtpu filmthe thickness error is still large. in this case, if you want to win more market share, you need advanced production lines with good measurement and control technology.

due to poor control of the raw material ratio and reaction temperature of the tpu film, many customers were dissatisfied and complained.tpu filmproduct thickness error.

but here, i still want to say one thing:tpu filmthe thickness is really difficult to control!

becauseTPUthe film manufacturer is elastomer, so after drying and dehumidification, the film is extruded through a die after being mixed and matured by a screw. any factors in between, including raw material instability, may lead to uneven film thickness.

generally speaking, the industry says that it is normal for the thickness of 10 wires of tpu film to have a positive or negative tolerance of 1 wire (0.01mm). of course, this is also related to the thickness of the film. the thinner the tpu film, the smaller the acceptable thickness tolerance.

however, the testing equipment of advanced tpu film manufacturers is usually very expensive, so for many small and medium-sized tpu film manufacturers, controlling the thickness and scrap rate of the film is a headache.

to improve energy efficiency and reduce carbon emissions, the automotive industry is increasingly using lightweight materials, which is expected to boost the growth of the tpu film market. can be used in the production of automotive parts to help reduce weight (approximately 40% reduction). at the same time, they can also replace rubber parts in cars.

used in automotive applications such as doors and acoustic panels, instrumentation and anti-vibration panels, seats and airbags. the replacement or after-sales market is expected to become the new focus of the automotive industry's demand for tpu films.

consumers are now extremely price sensitive and price plays an important role in the market. in europe, north america and asia-pacific, the price trend of the tpu film market has increased by 25% to 35%.
