Materials Library - Cyclic Olefin Copolymer (COC)

Knowledge Base

Everything you need to understand plasma technology all in one place.

The majority of common engineering polymers have inherently low surface energy and therefore exhibit poor adhesion characteristics. Plasma treatment offers a reliable and environmentally friendly method of both cleaning and activating the polymer surface, increasing the surface energy and wettability, resulting in greatly improved adhesion characteristics.

"In 2024, we needed a plasma cleaner for rapid prototyping and PDMS microfluidic bonding. Henniker Plasma quickly identified the right system and provided practical PDMS bonding guidance. The system was delivered within 8 days, enabling us to start R&D earlier than planned. Same-day technical support and protocols have greatly accelerated our research."

Aaron Teo - Vivid Dx

"The technical team at Henniker are very knowledgeable and supportive and always approachable. I have found it a pleasure to work with them."

Simon Baxter - BAE Systems, MAI

"Henniker guided us to choose the most suitable plasma unit for our application, ensured an accelerated delivery time & guided us through the very easy setup. We obtained quality results with their unit within minutes of setup & consistent results thereafter. The support they have provided has been rapid and helpful."

Dr Ravi Desai - Making Lab, Francis Crick Institute

"Henniker provided our team with excellent service during the course of our work together, the plasma cleaner arrived quickly and was installed with ease, giving us visible results from the outset and confirming that we made the right decision in choosing a local UK manufacturer."

Dr Panagiotis Manesiotis BSc MRSC - Queen’s University Belfast

"Our customers and operations demand reliability at every level and were a key factor in our decision to choose a UK based manufacturer of plasma treatment equipment."

Tom Doak - Trak Microwave
