tpu film is a thermoplastic elastomer that is widely used in medical, automotive, electronics, aerospace, sports equipment and other fields. in the production process of tpu film, you need to pay attention to the following points: raw material selection: choose high-quality raw materials to ensure tp

tpu film is a kind of plastic, so when storing it, you should pay attention to avoid high temperature, ultraviolet rays and moisture to ensure its quality and performance: 1. storage temperature: it should be placed in a dry, ventilated and cool place to avoid direct sunlight and high temperature. storage temperature

a customer asked, does the thicker the tpu waterproof and breathable membrane have a higher waterproof rating? the editor of fulian tells you that the thickness of the tpu waterproof and breathable membrane has little to do with the waterproof level. in order to let everyone understand this, let me analyze it now. tpu waterproof and breathable membrane is a polymer waterproof material, which is composed of a flexible and rich...

the reason why traditional glues are not environmentally friendly is that their ingredients contain toxic and harmful substances, such as formaldehyde, or they require the use of some toxic and harmful solvents to achieve viscosity. then we will analyze from these two points. first, the component of tpu hot melt adhesive film is tpu (polyurethane), which is a safe and harmless...

with the progress and development of the times, many smart devices are also constantly developing. at present, children's consumption is receiving more and more attention. children's smart watches are one of the anti-lost products for many families. because children are in contact with smart watches for a long time, they are very harmful to them.

generally, the thickness of tpu films on the market is 0.012-0.025mm, and the thinner they are, the higher the moisture permeability. of course, the thicker the water pressure, the higher it will be. moisture vapor permeability is a very complex issue because of different testing methods. for laymen

chemical resistance of tpu film. tpu film cannot resist strong polar solvents as well as strong acid and alkali media. at certain temperatures, alcohols, acids and ketones can swell and degrade polyurethane elastomers. solvents such as methylene chloride and trichlorethylene will cause tpu to

at present, the thickness error of mass-produced tpu films in the world is still very 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 the raw material ratio and reaction of tpu film

1. shoe material tpu film is used as shoe-making material mainly because of its excellent elasticity and wear resistance. in terms of wearing comfort, footwear products containing tpu are much more comfortable than ordinary footwear products. therefore, they are more widely used in high-end

it is generally believed that traditional tpu is heat-resistant to 80°c, which means that its long-term use temperature cannot exceed 80°c, otherwise its service life will be greatly shortened. there are also heat-resistant tpus that are said to withstand temperatures up to 130°c. there are also
