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.

tpu hot melt adhesive film and eva hot melt adhesive film are the two most frequently used types of hot melt adhesive film products in the hot melt adhesive film industry. they are widely used in the field of textile composites and are involved in the development and application of materials in many industries. then there is tpu

tpu hot melt adhesive film is currently a widely used hot melt adhesive film product. it is widely used in clothing, shoe materials, packaging and other fields. its usage is second only to eva hot melt adhesive film. so, what are the specific characteristics of tpu film? making it so widely used

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

tpu films are used in the automotive industry to reduce the weight of automotive parts, thus improving overall performance and efficiency. these films are used in the engineering and design of automotive parts such as interior door panels, seat padding and thermal insulation. on the contrary, raw material prices rise and more and more

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
