Henan Zonghai Plastics Co., Ltd

Flexitank

Our Bitumen Flexitank (High-Temperature Flexitank) is specially engineered for the bulk transportation of hot bitumen / asphalt and other high-temperature non-hazardous liquids. Designed to withstand temperatures up to 120℃, it allows hot asphalt to be loaded directly from production facilities without waiting for cooling.

 

The high-temperature-resistant PE inner bag is designed to dissolve directly into the bitumen during unloading, meaning no residue remains and there is no need to remove or clean the inner bag – making it highly efficient and cost-effective for asphalt transport.

 

Fitted into standard 20ft dry containers, the bitumen flexitank provides a simple and economical alternative to heated tank containers and dedicated bitumen tankers. Unlike competing products that require 12-24 hours of cooling time after loading, our bitumen flexitank is ready for transport immediately after loading – no waiting required, significantly speeding up your logistics turnaround.

Typical Applications

Product Category Specific Examples
Asphalt & Bitumen Paving grade bitumen, polymer modified bitumen, asphalt cement
Road Construction Bitumen emulsions, road asphalt, waterproofing bitumen
Roofing Materials Roofing bitumen, waterproof membranes raw material
Other High-Temp Liquids Hot oil products, waxes, other non-hazardous high-viscosity liquids
Industrial Resins Low-melt resins, hot-melt adhesives (non-hazardous)
Heavy Oils Heavy fuel oils, residual oils, bitumen blends

 

Unloading Process (Bitumen)

  1. Heat the container– apply external heating (steam coils or heating jackets) to bring the bitumen back to liquid state
  2. Connect discharge hose– attach hose to bottom discharge valve
  3. Pump out the bitumen– hot bitumen flows out, carrying dissolved PE material with it
  4. Complete discharge– inner bag fully dissolves, no residual material to remove
  5. No cleaning needed– container can be returned as-is or used for other purposes
