Product information of Ship Launching Balloon
Executive Summary
Product Names: Marine Airbag, Ship Launching Airbag, Ship Salvage Airbag, Inflatable Airbag, Ship Lifting Bag, Air Balloon.
Material Composition: High-tensile natural rubber compounded with multi-layer rubber-dipped synthetic-tire-cord fabrics.
Core Applications: Vessel launching & drydock landing, heavy-tonnage block shifting, and marine salvage/stranded boat recovery.
Target Clientele: Global shipyards, ship owners, port authorities, and marine supply companies.
Ship launching airbags are to be constructed of an out rubber layer, multi layer heavy-duty synthetic-tire-cord layers, and an inner rubber layer vulcanized firmly. Ship launching airbags are cylindrical balloon body, with two conical head and end mouth. Air tightness swivel and air inlet kits are screwed with end mouth.
• Synthetic-tire-cord layer is reinforcement layer of the ship launching airbags which are made of rubber coated synthetic-tire-cord fabrics. Many synthetic-tire cord layers are twined at ideal angles by unique and patented "Holistic Wrapping Technology". To hold the internal pressure and to distribute the stress evenly. The warp is over 95 cords per 100 mm in width. The breaking strength is more than 310 N per cords.
• The outer rubber layer covers the outside of ship launching airbags. To protects the cord layers from abrasion and other external forces. This compound has sufficient tensile and tear strength to withstand any weather condition and hard usage.
Our properties requirements of outer and inner rubber material comply with ISO 14409.
Acceptance Test for Commercial Ship Launching Balloon
Our test the ship rubber airbags purchased based on the test items indicated below:
* The appearance of the airbag is free from defects such as blemishes, bubbles, cracks, etc.
* The diameter, length and working pressure of each air bag need to be tested before shipping.
* The airtightness test of the airbag complies with the ISO 14409 standard. Air loss per hour does not exceed 5%

Frequently Asked Questions (FAQ)
Q1: What materials are Florescence ship launching balloons made of?
A: Our airbags are fabricated from premium raw natural rubber and multiple layers of rubber-dipped synthetic-tire-cord fabric. This multi-layer matrix ensures exceptional tensile strength, elasticity, and resistance to aging and abrasion under harsh maritime conditions.
Q2: What are the primary applications of these marine airbags?
A: Beyond traditional ship launching and landing (upgrading/docking), they are widely utilized as pneumatic lifting bags for moving heavy dimensional structures (up to tens of thousands of tons) and as buoyancy units for marine salvage and refloating stranded vessels.
Q3: Can Florescence supply custom-sized marine airbags?
A: Yes. We offer a highly flexible manufacturing range with diameters from 0.8m to 2.0m, lengths from 5.0m to 22.0m, and structural reinforcements from 3 to 10 layers to perfectly match your project's specific deadweight and slope requirements.
