All of our standard products are available with Low Formaldehyde emissions, to meet the F (F-Three Star) and F (F-Four Star) Japanese Industrial Standard (JIS). JIS applies stringent criteria to resin inputs and formaldehyde emissions resulting in a tangible standard for consumer security. The F-Three Star standard is a maximum of 0.5 milligrams per litre (mg/l) of formaldehyde emission and the lower F-Four Star standard is maximum of 0.3 mg/l formaldehyde emission. We also meet other Emission standards, simply request your preference when you place your order This symbol appears on every JIS pack and illustrates our compliance with the JIS A 5905 standard. The RS designates the panel as "Base Board Polished", or sanded panel. The 30 relates to the minimum bending strength (Modulus of Rupture) of the panel, and is a conservative minimum for the full range of panels we make. The U is the classification according to the adhesive or resin used, and signifies that Urea based resin is the main component. NAF - No Added Formaldehyde Should you want to avoid formaldehyde emissions altogether, talk to your sales representative about Patinna-NAF (no added formaldehyde) products, for the ultimate environmental consideration. As with all our products, you can also request 100% FSC(Forestry Standards Certification) wood be used to make your low formaldehyde emission panel.

Patinna Low Formaldehyde Fiberboard, Patinna Low Emission Fiberboard. Patinna Low Fy fiberboard can be made many ways: FSC, Pure FSC, Mixed-Sources FSC, CARB MDF, LEED credit MDF, Low fy emission mdf, NAF mdf NAUF mdf, Phenolic MDF and more. Patinna Low Formaldehyde Fiberboard is a versatile fiberboard which can be made with No-added-formaldehyde or no-added urea-formaldehyde resin. This is our NAF and NAUF product, and can also be made with FSC, Forest Stewardship Council sourced sustainable wood resource. FSC MDF and Pure FSC MDF: We can do Pure FSC content Low Formaldehyde, we can do Mixed-Sources FSC in Low Formaldehyde Fibreboard. Pure FSC low emission fibreboard means 100% of the fibre source is from FSC Certified forests. Mixed-Sources low formaldehyde fiberboard means that a minimum of 50% of the wood used to make the high density fibreboard panels is from FSC Certified forests. Low Formaldehyde Emission or Low Fy MDF: Patinna Light, Medium and High Density Fiberboard is available as low formaldehyde emission fibreboard. Low formaldehyde emissions are critical in today's environmentally aware world. Low fy panels can contribute to a cleaner environment for everyone. Our low fy mdf meets JIS standards for F3S and F4S low formaldehyde emissions. We can also meet many other international low formaldehyde standards for Low Formaldehyde Fiberboard panels. CARB MDF: Patinna Low Formaldehyde fibreboard can be provided as CARB compliant under both Phase 1 and Phase 2 emission levels. We have CARB compliant mdf and hdf which is third party certified under TPC-005. CARB mdf and hdf is available now from Dongwha Patinna MDF and we are shipping low formaldehyde emission CARB MDF to the USA and the world right now. LEED credits: Patinna Low Formaldehyde fibreboard with low emissions and made with FSC wood resource can contribute to LEED credits under M&R 7.0 and IEQ 4.0.
