What is PVC

Polyvinyl chloride (PVC) stands as the third most widely manufactured thermoplastic on a global scale. It exists in both rigid and flexible forms, deriving primarily from raw materials extracted from oil and salt. Notably, PVC demonstrates eco-friendly characteristics by consuming less crude oil and natural gas during its production compared to alternative plastics, rendering it an appealing option for diverse applications.

Understanding PVC Welding

PVC, or polyvinyl chloride, is a widely used thermoplastic polymer known for its durability, versatility, and resistance to corrosion. PVC welding involves joining two or more pieces of PVC material using heat and pressure, creating a seamless bond that is both strong and long-lasting. This process is commonly used in industries such as agriculture, construction, automotive, and more.

Why RF or HF for welding PVC?

Choosing the right sealing technology depends on factors such as material, product size and shape, and production volume. Radio Frequency (RF) Welding, also known as High Frequency (HF) welding offers consistent, clean seams without adhesives or solvents. For regularly producing identical products with specific weld shapes, RF Welding is ideal.

RF welding, or HF welding, is the best method for joining PVC and PU materials. It produces much stronger welds compared to hot air, hot wedge, or impulse welding, and the resulting welds are both airtight and waterproof.

Why HF?

There are other technologies than high frequency (also called radio frequency) welding which can be used to join sheets of PVC and PU materials. So, why use high frequency (HF) rather than other technologies?
