Like other fabrication processes that SealWerks offers, the strength of the radio frequency welding process depends on the types of materials involved. RF welded seals last as long as the original materials are expected to last, provided the product doesn’t experience damage. However, the radio frequency welding process is intended to help reinforce the strength of the material, helping to prevent damage.
RF Sealing Makes Products Tougher
Through radio frequency sealing, a tear-proof airtight and watertight seal is formed, which increases the overall durability of the materials in a product. The materials used in the RF sealing process need to have a polar molecular structure, the most common of which are polyurethane and PVC vinyl. However, certain coated materials are also usable. TPU and TPE type materials are also suitable for RF welding, along with PETG, EVA and PET plastics.
The key to having a long-lasting product following the radio frequency welding process is in the strength of the materials used. SealWerks can advise you about which specific materials work best with our sealing processes, and determine if your product would benefit from the RF welding process or another sealing method, such as hot air sealing or hot wedge welding.
How RF Welding Strengthens Material
During the radio frequency welding process, the similar or dissimilar materials used become thicker and heavier as they fuse together. Electromagnetic waves generate heat and cause the molecules to loosen and scramble, fusing the materials into a single product. The resulting seal is watertight and airtight, and combines the strength of both materials.
