As a leading marine equipment manufacturer, Henger Shipping Supplies is frequently asked about the materials used in its products. One common question is whether sulfurized rubber airbags contain talcum powder. Given the importance of these airbags in ship launching, landing, and salvage operations, this question is of critical importance.
Ship launching airbags, also known as roller airbags or inflatable marine airbags, are designed to be robust and reliable. They are constructed from heavy-duty synthetic tire cord layers and inner and outer rubber layers, forming a long, cylindrical airbag. Understanding the manufacturing process and materials used in these airbags is essential for ensuring the safety and reliability of maritime operations.

Understanding Vulcanized Rubber Airbags
Ship launching airbags are specialized vulcanized rubber products designed specifically for ship launching and upgrading. With their new way of launching ships, vulcanized rubber airbags have changed the marine business forever. If you want to avoid the problems caused by end-to-end drainage, side-to-end drainage, and floating drainage. Then, these rubber airbags are a good choice.
Having a circular balloon form with conical ends makes them ideal for smooth rolling during ship launching. Using vulcanized rubber airbags has many benefits, such as saving time, money, being flexible, and making things safer.
What Vulcanization Does for Making Airbags
The vulcanization process transforms raw rubber into a durable, elastic material. This makes it stronger and more elastic. This process is crucial for giving airbags the right properties. As a result, they can withstand high pressure and heavy loads during the launching of ships.
Using vulcanized rubber airbags is a flexible and effective way for builders to launch ships. This method is becoming more popular around the world because it works well and is reliable.
The Role of Talcum Powder in Vulcanized Rubber Airbags
French chalk which is another name for talcum powder. It is used in the vulcanization process of rubber airbags for a specific scientific reason. During the vulcanization process, we use talcum powder as a release agent. This keeps the rubber sides of our airbags from sticking together when they are heated and pressed together.
Why Talcum Powder Is Used: The main reason we use talcum powder is to keep our vulcanized rubber airbags working the way they were meant to. Talcum powder helps the rubber cure properly by keeping the layers from sticking to each other. This makes the end product of high quality.
The Vulcanization Process and Powder Application: The rubber mix is heated and pressed under high pressure during the vulcanization process. We put talcum powder on the rubber surfaces to keep them from sticking. This application is very important for making ship launching airbags and other kinds of rubber airbags.
Common Misconceptions About Powder Residue: Many people think that new vulcanized rubber airbags look dirty or used. This is because they are covered with talcum powder. When the French chalk and water mist in the vulcanization tank, they leave behind a layer that might make new airbags look dirty. This dust doesn’t change how our vulcanized rubber airbags work or how well they are made.
Customers should look for damage or deformation on the airbags to tell the difference between normal production residue and signs of real use or wear. There is no need to worry about normal dust damaging the airbags.
Construction and Materials of Vulcanized Rubber Airbags
Henger Shipping Supplies vulcanized rubber airbags are made with a strong, multi-layer design that makes them strong and reliable. This design is very important for making sure that the rubber airbags can handle the rough conditions of the ocean and the stress of launching a ship.
Outer Rubber Layer Specifications: The top layer of rubber is made with certain tension and tear strengths to protect against wear and tear and outside forces. It is very important that this covering keeps the inside of the airbag from getting damaged.
Synthetic-Tire-Cord Reinforcement Layers: The layers of synthetic tire cord reinforcement are made of synthetic tire cord fabrics that have been covered in rubber. Our unique “Holistic Wrapping Technology” twists these layers together at the right angles. We use synthetic tire cord cloth of the 1400 dtex/2 or 1400 dtex/3 type, which has more than 95 cords per 100 mm width and a breaking strength of more than 310 N per cord.
Inner Rubber Layer Properties: The inner rubber layer is meant to keep the air pressure steady and give the airbag more structural strength. This layer, along with the top layer and support layers, makes sure that the airbag works well and lasts a long time.
Our vulcanized rubber airbags are made up of multiple layers. This makes them strong enough to handle high internal pressure. Plus, they can spread out stress during ship launching. At the end shoulders, extra strengthening layers are added to give the structure more strength at these high-stress areas.
Types of Vulcanized Rubber Airbags
To meet the demands of various types of boat launches, we provide three very effective boat launch airbags. We can provide customized choices to satisfy a range of requirements. This ensures that your ship’s launching mission is successful.
QP (General Purpose): For medium loads, 3-5 layers of curtain design are often utilized on most ships.
QG (High Load Type): With 6-8 layers of cord fabric, it is better suited for heavy-duty ship launches and has a higher load carrying capability.
QS (Ultra High Load Type): Designed specifically for extremely heavy loads, using 9 or more layers of curtain fabric. Maintains stability even under the heaviest loads.
The number of layers in synthetic tire cord is directly related to the safe working pressure and overall load capacity of each type of airbag. We can provide customized specifications that exceed the standard product range according to customer requirements. This can meet customers’ special application needs.
Applications of Vulcanized Rubber Airbags
We use vulcanized rubber airbags in a variety of maritime and commercial settings to show how useful and flexible they are. These airbags are mainly used for ship launching and conversion. This indicates that they can handle ships of various shapes and sizes.
Ship Launching and Upgrading: Most of the time, vulcanized rubber airbags are used to launch ships. Our ship launching rubber airbags have been used to safely launch barges, chemical tankers, tugboats, AHTS vessels, floating docks, and even building caissons. Up to 100,000 DWT has been the biggest ship launched with this technology.
Marine Salvage Operations: Marine salvage operations also use vulcanized rubber airbags to help refloat stuck ships, recover wrecked ships, and finish underwater recovery projects. Because they are flexible and can change, they can handle difficult underwater jobs.
Heavy Lifting Applications: Our airbags are used for more than just launching ships. They are also used for heavy lifting, like moving big buildings and concrete caissons, and can lift more than 1,000 tons each.
In addition, it can also be used for installation buoyancy on pipeline float-out, beach pulls, river crosses, lowering the draft of vessels and platforms, and supporting floating bridges. Vulcanized rubber airbags are great for a lot of different naval and industrial applications because of their flexibility.
Conclusion
Choosing the right vulcanized rubber airbag is crucial to ensuring smooth offshore operations. We want to say again that talcum powder is used to make vulcanized rubber airbags. This is a normal process that ensures the quality of the product.
At Henger Shipping Supplies, we adhere to strict quality standards and provide appropriate certification for our rubber airbags. It is very important to buy high-quality airbags with the right pressure and carrying ability. When used correctly, an airbag that is made correctly can last between 5 and 8 years.
Customers are welcome to ask our expert team for help choosing the right type of airbag. We offer great goods and great customer service because we’ve been in business for years.
