XIMOFILM · The first ultra-low extractable silicone film release liner for electronics, silicone adhesive market and medical applications

Today, silicone contamination is one of the main challenges for players of the electronics sector which require the use of Pressure Sensitive Adhesives (PSA). Silicon contamination can drive to 10-20% of defective products. The release liners used for this PSA require low levels of extractible silicone (<20 ng/cm²). Besides, the adhesives used in the electronic market are solvent based. Today, solvent resistant release liners present still high levels of extractible silicone. On the other hand, those release liners with low extractible silicone are not solvent resistant and often do not present high subsequent adhesion. XIMOFILM is also a release liner addressed to the medical sector, where silicone and soft silicone gel adhesives are increasingly used. In this sector the release liners must also present low level of extractible silicones. Founded in 2001, CPI is a spin-off French pioneering company offering complete service for industrial atmospheric plasma integration addressed to professionals of packaging, printing, polymer transformations and textiles. Thanks to the optimisation and industrialisation of our cold atmospheric plasma technology, CPI will offer the first ultra-low extractable film silicone release liners with good release force properties (low) and high subsequent adhesion of the adhesive (more than 90% compared to 65% of current competitors), solvent resistant and with very low silicone contamination (<10ng/cm²). The production cost will be also reduced, allowing to purchasing prices 30% cheaper than our competitors. For this Phase 1, we will focus on the technical and financial feasibility of XIMOFILM process and well define the business model to extend our commercial network to Europe and Asia. For CPI, this project will imply a ROI of 9% in 2024. For end users, XIMOFILM will represent an opportunity to reduce damaged final products due to silicone which would save them up to 15% due to after sales services and wasted devices.
