Waterproof zippers, as their name suggests, are specially made to prevent penetration of liquid. The most common and usual application of waterproof zippers is on different outdoor gear and equipment to offer protection from the rain.
But, the application is not just limited to this since you can also find them on different products like cotton-waded jackets, ski suits, raincoats, diving suits, tents, waterproof shoes, waterproof bags, and fishing wears.
There are many factors you need consider when buying and using a waterproof zipper. Below are a few key factors that will help you find the one that will best suit your needs.
For printed or patterned fabrics such as logos, you should choose waterproof zippers that are meant for printed fabrics.
If you will need temperature resistance low and high alike, you can choose imported PU waterproof zippers or TPU waterproof zippers.
As for uniforms that feature special signs such as army or police uniforms, you must opt for reflective waterproof zippers in order to maintain visibility.
For industrial applications and heavy-duty tests where frequent pulling back and forth of the zipper pulls is sometimes involved, the best choices are imported PU waterproof zippers.
In general, imported PU waterproof zippers are the most expensive option, followed by TPU waterproof zippers. If you are on a tight budget, PVC waterproof zippers are usually the most affordable choice.
Color Fastness or Color Differences
When going for colored waterproof zippers, it is important to consider the color difference between the zipper film and the zipper tape. The color difference must be ideally controlled at least 5% to maintain the right aesthetic balance.
For maximum uniformity of color on the surface with little to no turbidity point, it is recommended to choose colored film waterproof zippers.
You also need to consider the color fastness or the resistance to fading or running when buying waterproof zippers.
A waterproof zipper must be environmentally friendly and pass the standard certification or to ensure that their use won’t pose any threat to the planet.
The surface of the film must feel smooth and flat. In general, it is better if the film is smoother.
You need to choose a film that will not come off easily even after repeated exposure to high or high temperature and frequent washing. A high-quality film can help ensure the durability of waterproof zippers.
The center seam’s width will primarily determine the zipper’s waterproof performance. When the central seam is wider, it means that its waterproofing quality also gets worse.
Simply put, it is best to always look for a reliable supplier of waterproof zippers and try to strike the perfect balance between the waterproof quality, application, waterproofing film, budget, color differences or color fastness, surface smoothness, and eco-friendliness.
A reputable zipper supplier can provide you with an extensive and wide selection of quality waterproof zippers that will give you the best value for your money.
