30 Extrusion International 3/2025 INDUSTRY NEWS New PPS Coating Grade Introduced Syensqo has introduced a new Ry - ton® polyphenylene sulfide (PPS) coating grade, custom-engineered to resolve unmet needs in ease of application and achieving strong coat performance at lower builds. This coating grade offers an effi - cient coating process that allows for better deposition per pass. As a result, it reduces the time and re- sources required for coating, while maintaining high throughput of coated articles. “With this innovative Ryton® so - lution, we are responding to an in- dustry trend that focuses on more easily applied high-performance coatings with a smaller health, safety and environmental (HSE) footprint,” explained Hong Chen, Principal Research Scientist at Syen - sqo. “Building on our proven PPS chemistry, it delivers high barrier properties, provides excellent resis- tance to corrosive chemicals, dem- onstrates good adhesion to metals, and can operate at temperatures up to 200°C.” Ryton® PPS M2000 FP supports clients who seek a sustainable, low-volatile powder coating solu- tion that combines high molecular weight with safe application, op- timized coating build and minimal post-curing after film formation. Boris Makhinson, Syensqo Ameri - cas Market Manager for Energy concluded: “The new Ryton® grade extends our PPS chemistry to pow - der coatings for use in demanding environments, such as the oil and gas industry. It makes the coating job easier and safer for applicators and is commercially available world- wide.” Ryton® is a registered trademark of Syensqo.

Plasmatreat is setting new stan - dards in plastics processing with its innovative developments Openair- Plasma and PlasmaPlus. Openair-Plasma (atmospheric pressure plasma) developed by Plasmatreat can be used to change the surface properties of plastics. The activation that occurs when the plasma jet strikes the surface optimizes wettability and signifi - cantly increases adhesion. This re - sults in long-term stable adhesion of adhesives, paints, varnishes, liquid or solid sealants. PlasmaP - lus, another process developed by Plasmatreat, also makes it possible to coat plastics with a nanocoating that improves adhesive adhesion while eliminating the need for en- vironmentally harmful chemicals such as primers. With its beneficial properties, plasma technology plays a key role in implementing the three basic princi- ples of sustainability - reduce, reuse, recycle - in the plastics industry: • Reduce: By using plasma tech- nology, plastics production can be made more resource efficient, as plasma treatment increases the compatibility of plastics. Energy- intensive, expensive materials can be replaced by cheaper and more resource-efficient alternatives, such as recycled plastics. • Reuse: The life of plastic products is significantly extended through the use of plasma. Products can be used and reused for longer periods of time due to the improved adhesion and resistance achieved through plasma surface modification. • Recycling: A key benefit is the improved processability of recycled plastics. Plasma pretreatment makes these plastics more usable, allowing them to be recycled and reducing waste. Plasma technology also ensures more environmentally friendly pro- duction processes. Openair-Plasma treatment requires only compressed air and electricity to operate, is sol- vent-free and reduces the need for environmentally harmful chemicals. This not only conserves resources, but also reduces CO 2 emissions and improves the environmental perfor- mance of many industrial processes.
