For waterproof socks gloves PU waterproof breathable membrane with double-sided hot melt adhesive dots

There is no accurate data for TU1513 and DU1513 because they have not been specifically tested. According to the data provided by the film supplier, the moisture permeability of TU1513 is about 3000, while that of DU1513 can reach 12000, and that of JU1513 is 20000.

Yes, you need to send us the final shape drawing, and we will calculate the price, including product price, mold price, etc. Usually there is no minimum order quantity, but the product price will be higher when the quantity is small. And the mold fee can be returned to the buyer or deducted from the future payment, but it needs to meet a certain payment amount.

TPU/PU waterproof and breathable membrane is not breathable and can only pass a certain amount of water vapor. Therefore, we usually do not talk about waterproof and breathable membranes, but waterproof and moisture-permeable membranes. The data is also based on the water vapor permeability within a certain period of time.

We can provide free samples to facilitate your testing. But we cannot bear the international logistics costs. It is best if you have a DHL, FedEx or TXT account.

When we sell by the yard, because it is a coil, we usually pack it in woven bags for delivery; if it is a special shape, we will pack it in cartons for delivery.

Store in a dry place at room temperature and avoid direct sunlight. Theoretically speaking, the product has no shelf life limit, but it is not recommended to leave it for more than 18 months when it is not in use.

We support T/T, PayPal, Alipay, WeChat and other payment methods, and can provide FOB, EXW, CIF, DDU and other methods of quotation. The lead time varies according to the product model and quantity, usually between 3-30 days.

This is because the products produced need to have good stretchability. Take socks as an example. If my shape is made the same size as the actual socks, because the film is not like fabric and does not have particularly strong elasticity, when the customer wears the socks, the film is likely to be torn and the product will be damaged. Therefore, it needs to be made very large. However, due to problems with the production process during production, the final product is not much different from regular socks and does not appear to be very large.

Take socks as an example. You need to make a metal mold of similar size according to the drawing. It is flat. Then put the inner fabric, waterproof membrane and outer fabric of the socks into the mold in turn. At this time, the socks are stretched very large. Then heat press the front and back to make the glue points on the film melt and bond the inner and outer sock fabrics together. Then take it off the mold for water leakage detection. The passed product is wet at this time. Put it into a mold of the actual size of the socks and bake it in the drying room. The product returns to its original shape.

Yes, compared to PU film, TPU film is smoother, which makes it easier to be put into the mold and less likely to be damaged by friction.

Yes, but the impact is not significant. Of course, we can also make the spacing between the hot melt glue points larger, so that the impact on moisture permeability will be smaller.

TU1513 has the lowest cost, followed by DU1513, and the highest is JU1513. Of course, in terms of moisture permeability, JU1513 also has the best performance. TU1513 is a TPU waterproof and breathable membrane, while JU1513 and DU1513 are both PU waterproof and breathable membranes.Although TU1513 has the lowest cost, DU1513 is the best in terms of cost performance.

PU waterproof and breathable membrane is hydrophilic, while TPU is water-repellent. That is to say, DU1513 and JU1513 are hydrophilic, while TU1513 is not. Therefore, compared with TU1513, DU1513 and JU1513 have better breathability and are more comfortable to wear when made into gloves and socks.
