Difference between 8# TPU waterproof zipper & 8TZ CR airtight zipper.

1.        Different waterproof zipper tape, 8 # TPU zipper with TPU tape, and 8 TZ CR zipper with Neoprene.

   Neoprene (also polychloroprene or pc-rubber) is a family of synthetic rubbers that are produced by polymerization of chloroprene. This is the same fabric used by scuba divers and surfers for their wetsuits. It a high-quality material that holds up during competitive sports. It has several desirable features: Strong and resistant to tears, Completely waterproof and repels spills, Comfortable feel that does not irritate the skin. Neoprene exhibits good chemical stability and maintains flexibility over a wide temperature range. Neoprene is sold either as solid rubber or in latex form and is used in a wide variety of applications, such as laptop sleeves, orthopaedic braces (wrist, knee, etc.), electrical insulation, liquid and sheet applied elastomeric membranes or flashings, and automotive fan belts. Neoprene is produced by free-radical polymerization of chloroprene. In commercial production, this polymer is prepared by free radical emulsion polymerization. Polymerization is initiated using potassium persulfate. Bifunctional nucleophiles, metal oxides (e.g. zinc oxide), and thioureas are used to crosslink individual polymer strands.

   Thermoplastic polyurethane (TPU) is an elastomer that is fully thermoplastic. Like all thermoplastic elastomers, TPU is elastic and melt-processable. Further, it can be processed on extrusion as well as injection, blow and compression molding equipment. It can be vacuum-formed or solution-coated and is well suited for a wide variety of fabrication methodologies. Thermoplastic polyurethane (TPU) is any of a class of polyurethane plastics with many properties, including elasticity, transparency, and resistance to oil, grease and abrasion. Technically, they are thermoplastic elastomers consisting of linear segmented block copolymers composed of hard and soft segments.

The airproof zipper is the most sensitive part of a drysuit and, as such, it requires some care after use. With proper maintenance, drysuit zippers can last a very long time.

Take a look at some of the steps that can be taken to keep the drysuit zippers clean and operating smoothly.

Cleaning the Drysuit
After each use, the suit needs a good cleaning to make sure that salt and other contaminants get washed out of the zipper. It’s important to wash off the entire drysuit — both inside and out and make sure that any sand or dirt that has accumulated in and around the zipper is thoroughly washed off. If a piece of dirt gets stuck in the zipper, do not try to force the zip to close — clean it first and then zip the drysuit up.

Never machine wash or dry clean the drysuit — this can damage the zippers.

Once the drysuit has been washed, it’s best to hang it up — either with the help of a drysuit hanger or upside down so that it is thoroughly drained.

Storing the Drysuit
Store the drysuit in a cool or dry place — high temperatures and humidity can cause damage to the zipper.

When storing the drysuit keep in mind that it’s best to place it on a hanger in the upright position. However, if this is not convenient, make sure that the zipper doesn’t fold in too many places and. Store drysuits with metal zippers open while you should store drysuits with plastic zippers closed.

If the drysuit won’t be used for a while, a few steps can be taken to keep the zipper in the best possible shape while it is stowed away. One of the most important steps is to cake a layer of paraffin or bees wax or a specially designed lubricant on the zipper. This will keep the zipper flexible and easy to operate whenever it is used again. However, the use of wax should be tailored to the type of zipper on the drysuit-metal or plastic. Run a block of paraffin or bees wax over the metal zipper teeth. But do not wax the plastic zipper teeth. Apply some petroleum jelly over the surfaces near the end stop.

The main application for 8TZ CR close end airtight & waterproof zipper

The 8TZ CR close end airtight & waterproof zipper can be used for below products:

Dry suit

Chemical protective suit

Water walking ball

and other sealed suit and products

Once dry, it is very important to store the gasproof zipper fully closed in a relaxed position, not pinched or folded. Take care of that you should not to scratch or stretch the zipper when loading.

Before storage clean with mild soapy water, rinse, dry, lubrifiant! Lubricating the zipper will keep the rubber from drying out. Make sure zipper is dry, lubed, fully closed, and not folded or pinched for storage.

When packrafting with your packrafter friends, you should always carry zipper lubrifiant in your repair kit, it is essential for the proper function and longevity of your zipper. In addition to ensuring proper function of the airtight zipper , the lubrifiant protects the gasproofzipper from drying out and from UV damage. How to care for and storage the airtight zipper. Dry your zipper. Bacterial growth is your zipper’s biggest enemy. Bacterial growth will cause the rubber of the zipper to crack  and leak. It is very important to fully dry your zipper after each use. The cloth backing of the zipper holds the most water. Dry the airtight zipper by leaving it open for a day in a dry area, and longer when using your zipper in warm or tropical fresh waters. In wet/ humid areas you may wash the zipper occasionally with mild soapy water. Rinse well. Once dry, it is very important to store the zipper fully closed in a relaxed position, not pinched or folded. Take care of that you should not to scratch or stretch the zipper when loading.
