Purpose of this project was to develop waterborne polymers that are suitable for polyethylene and polypropylene surfaces. Main research areas were polymer morphology use of specialty monomers Teemu at work in CH-Polymers’ laboratory ”I made my Master’s thesis for CH-Polymers, as part of their Adhesion project. I can certainly say that the project was interesting and it gave me and CH-Polymers additional information about morphology and adhesion.” –Teemu Piesanen, M.Sc. It is known that achieving adhesion to inert polyolefins is difficult without any surface treatment. Contact angle measurements and other adhesion analysis methods were used to characterize the performance of the polymers. As a conclusion a 40 % increase in adhesion was achieved. This is a great result in our multipurpose products. Teemu will continue his work at CHP laboratory. We are keen to know what he comes up with next! “Understanding the interactions between different materials opens brand new ideas to be applied in our product development. ” -R&D Manager Gun Lundsten
SLF Congress in Copenhagen 27.-28.9.2018 Better exterior house paints A study of Nordic exterior house paints, all given good scores in a test by Folksam Insurance company, will be presented at the SLF congress in Copenhagen. One of the key findings is that there are many ways to formulate a high-performance house paint. A balance of several features such as adhesion, water absorption and flexibility is greatly influenced by the choice of the binder. An open mind and new approaches to formulation are a good starting point when formulating new paints using the latest technology. Gun Lundsten will demonstrate to you how to minimize undesirable features such as water uptake while allowing the film to breathe. This opens up new opportunities to protect our beautiful Nordic wooden houses. This technology has been developed and tested in Finland for demanding Nordic conditions.

Presenting new solutions to the industry is always a challenge. There are several steps to be taken from the bright idea into commercial solutions. First efforts in making barrier products were done already 30 years ago here in Raisio. Application area was packaging materials, paper bags etc. Back then the company was called Raisio Chemicals and it was also the same company that took the decison to build a dispersion plant in Kouvola, the plant that now serves as the production unit of CH-Polymers. From those days CH-Polymers has come a long way and proudly presents CHP BAR series at the PacTec 2018 exhibition in Helsinki. Changes in business environment such as Growing use of recycled fiber increases the significance of mineral oil barrier and Avoiding polyethylene films in packaging materials is gaining interest Sustainability is more than just a word, today it carries commercial importance and is a driver in many projects. Whenever foodstuff is involved, the safety issues cannot be compromised. Avoiding migration of harmful components such as mineral oils used in printing inks into foodstuff improves possibilities for recycling. CHP BAR plays a major role there. Ask more! Visit us at the PacTec exhibition @7e100 and we […]
CH-Polymers – working on replacing plastics and improving print quality CHP BAR for replacing plastics CH-Polymers´ new BAR series is a Water Based Barrier Coating (WBBC) and a solution for greener future. Barrier coatings against water, water vapor, grease and mineral oils are possible to be made using CHP BAR. Increasing consumption of fast food products growing demand of packages with barrier properties. Use of recycled fiber is a challenge for mineral oil barrier to avoid migration of oils from the packaging into foodstuff. All of these applications can be made with CHP BAR and the end product remains biodegradable and can be recycled like standard paperboard. Online coating at the board machine increases efficiency as no separate coating or converting process is required. Trim cuts on the machine can be repulped which increases the efficiency even further. A separate CHP BAR line has been developed to meet converters´ requirements. The product is ready to be applied as such – being environmentally friendly cannot be easier than this. No need to use polyethylene, wax or fluorochemicals anymore! VAcA (Vinyl Acetate Acrylate) series for super print image High speed printing has high demands for print substrate. Ink settling has to be […]
We are focusing on environment and safety! The newest example of our dedication is a novel acrylic polymer for use in demanding nonwoven applications. Formaldehyde free acrylic chemistry guarantees the performance, if it is durability, stiffness, strength or superior binding properties that you are after. The new product can be applied by spraying or impregnating, or in size press. Versatility is a clear benefit of any product. This we believe to have achieved. Our standard test process series is done with Mathis size press. Both wet and dry tensile strength were up +17% compared to the standard formaldehyde containing product. Let us know if we can help you to make a greener choice with our CHP 637! CH-Polymers Chemistry made to fit!
Towards improved surface sizing At PTS 2017 CH-Polymers and Chemec proudly presented with BTG Instruments our joint dive into deeper testliner surface sizing process understanding, based on a Master’s thesis work in collaboration with Åbo Akademi (Misla Lagus 2016-2017). More and more paper is used in packaging. Corrugated board is increasingly recycled based and recycled-based testliners need to have adequate water resistance. Surface sizing is an easy and cost efficient way of doing this, compared to internal sizing. Lack of understanding the surface sizing process variables still causes headache to the manufacturers. In our study different surface sizing agents were used to size base papers from several different sources. Basic paper analyses, surface sizing agent analysis, dynamic water retention (DWR) and Hg-porosimetry were done. We could find some interesting correlations with starch pickup, surface sizing agent performance and strength improvement in the size press. We could also replicate real on-machine problems in lab-scale, confirming the applicability of our methods. Our findings: Lab scale surface sizing performance correlates well with production scale performance. Confirmed applicability of our lab scale surface sizing method. DWR measurement can be used to predict starch pick-up in surface sizing. Hg-Porosimetry gave the most accurate porosity determination for […]
