The Evolution of PVC-O Technology: From Batch to Inline Processes

19 October 2023

Polyvinyl Chloride-Oriented (PVC-O) technology has been a cornerstone innovation in developing robust, efficient, and reliable plastic pipes. By examining the evolution of this technology and its development timeline, we can clearly see how trends in our industry have shifted over time.

The Early Days of PVC-O Technology

The nascent stage of PVC-O technology traces back to the earnest and innovative endeavors of the Petzetakis company in the 1970s. Incorporated due to its resource efficiency and technological feasibility, the then 'state-of-the-art' batch processing method was the initial preferred system for PVC-O pipe production. Companies embraced this process as it allowed ease of start-up given its comparatively low initial investment.

The Inline Revolution Begins

Advancement in PVC-O processing started its paramount shift when Wavin introduced the inline Apollo process in 1995. This ground-breaking process was engineered to optimize operational productivity and product quality. Since its commercial availability in 2003, Rollepaal has been the trusted manufacturer of this innovative process, facilitating its widespread adaptation across the industry.

Parallel Innovations

Innovation in PVC-O technologies continued its unfettered stride in parallel. With a vision of presenting an alternative inline processing mechanism, Uponor collaborated with Australian firm, Vinidex to develop the Cornet line. The Cornet line secured a strong global presence due to its exclusive features and proved that success is not a zero-sum game in PVC-O technology industry.

Expanding the Inline Landscape

Inline methods demonstrated their versatility and diligence when Alphacan and Pipelife devoted their resources in developing their own inline procedures. Their sheer commitment to creating more efficient and effective PVC-O processing methods was a testament to the technology's growth potential, promoting further expansion of the inline process landscape.

A Game-Changing Breakthrough

In 2006, Molecor unveiled a revolutionary approach by introducing a fashionable design of the batch process which is air based cooled. All previous PVC-O techniques used water as a cooling medium. Their innovative design injected fresh momentum into PVC-O technology and expanded its horizons. The dominant success and global commercialization of Molecor's method stand as vibrant testimony to the continuous progression and acceptance of PVC-O technology.

The Alternative Inline Solution

Rollepaal continued the enduring legacy of PVC-O innovation by developing RBlue process, serving as a good alternative to the traditional batch method and also with an air-based stretching. Launched in the market in 2012, RBblue emerged as a novel solution that stood apart with its unique features, further enriching PVC-O technology's competitive landscape.

Conclusion

Decoding the journey of PVC-O technology, from its inception with the robust batch processes to the emergence and refinement of inline strategies, narrates an engrossing story of evolving industrial innovation. Ongoing advancements animate the unfolding chapters of this journey, with the potential to trigger transformative developments in future PVC-O technology, promising enhanced functionality and broader applications.
