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.
Airproof zippers are zippers that have been specially designed and treated to resist damage from dust, chemical fumes, gases and above average atmospheric pressure. Usually made out of vulcanized chloroprene rubber, airtight zippers find use in a wide variety of industrial and chemical applications (e.g. decompression clothing, space suits, immersion suits, marine sportswear, etcetera).
Due to the nature of their construction, airtight zippers should be handled and treated differently from normal zippers. Here are a few tips on how they can be properly fixed and cleaned.
Fixing A Broken Zipper
The zipper can break if the cross-tension on the zipper chain is too high. Fortunately, this can be easily fixed.
①After cleaning the chain, check if the zipper is broken all the way down to the stopper. If so, read on.
②Slowly close the first inch of the zipper by hand. Make sure that the slider is in a closed part of the chain and pull the slider to the stopper.
③Open and close the zipper a few times and add wax on the chain for further lubrication.
Removing Dirt/Sand/Grime
Dirt, sand, and grime can cause the zipper to unnecessarily tighten and malfunction.
①Brush using a small soft brush or piece of cloth both the inside and outside of the zipper to ensure that there are no dust or dirt particles attached.
②Clean the zipper using a solution made out of mild soap and water, then rinse the zipper with clean water.
Applying Lubrication
①Fully open the zipper and apply the wax directly on the chain. But be careful not to apply too much wax. Space the wax application every four inches or so.
②Open and close the zipper several times to spread the lube.
③Wipe off the excess with a soft cloth.
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.
