What Specialty Formulation Materials are Suitable for RF Welding?
Specialty chemical products and other types of specialty products require corrosion and tear-resistant materials for containment. Some of these products use specialty formulation materials such as prepolymers and other polyurethane intermediates, thermoplastics, and other heavy-duty materials. Some of these materials are suitable for radio frequency welding, a unique process that can form a strong leak and tear-resistant seam, while others may require heat-sealing processes to form hermetically sealed seams.
Benefits of Using Radio Frequency Welding on Specialty Chemical Products
Unlike other sealing methods, RF welding uses a combination of electromagnetic energy and pressure to temporarily melt multiple surfaces and fuse them together at the molecular level. The resulting seam is fluid- and airtight, and is capable of resisting tearing when under physical stress for long periods. The seal that radio frequency sealing creates makes the process ideal for containment products including liquid bags for specialty chemical products. RF welded seams can eliminate leakage and wear for many years.
Specialty chemical containment requirements can use RF welding on products either constructed or coated with polar molecular materials such as PVC and polyurethane. Other types of specialty formulation materials will need other heat sealing services that we provide.
Some of the specialty chemical products at RF welded of heat sealed containers can hold include:
- Acids
- Epoxies
- Fuels
- Ink
- Toner
- Bleach
- Corrosion inhibitors
- Deicers
- Flakes
- Sealants
- Solvents
- Powders
There are many other types of products that can utilize heat-sealed or RF welded materials.
Using Other Heat Sealing Services for Products
For materials that are not compatible with RF welding, we also offer several other heat-sealing methods to form long-lasting seals that can eliminate leakage and contamination.
Our heat-sealing services include hot air and hot wedge welding. Hot air welding uses a nozzle to force heated air between two material surfaces, slightly melting them before using pressurized rollers to pull a heated metal wedge along two or more surface materials to melt them, and compression rollers apply pressure to fuse them together. The resulting seal in both processes is permanent and highly resistant to separating.
Are Specialty Formulation Materials Right for Your Product?
If you are unsure about whether or not your product needs specialty formulation materials in its construction, AmCraft Manufacturing can help with material selection. We will also help determine which sealing method is ideal for your product based on functionality, size, and other specifications. To further improve your product, we also offer redesign, reengineering, and prototyping services that can make sure your product is ready for production.
