Identifying additives to reduce the total amount of resin needed without adversely affecting the panel properties could reduce these impacts. Wollastonite is a mineral containing calcium and silica that has been used as an additive in a variety of materials and may be useful as a resin extender. Nanoscale wollastonite has been shown to enhance the panel properties but is costly. Micron-scale wollastonite may be a less costly alternative. Medium-density fiberboards were produced by blending a hardwood furnish with UF alone, micron-sized wollastonite alone, or a 9:1 ratio of UF to wollastonite. Panels containing of only wollastonite had poor properties, but the properties of panels with 9:1 UF\/wollastonite were similar to the UF-alone panels, except for the internal bond strength. The results suggest that small amounts of micron-sized wollastonite could serve as a resin extender. Further studies are suggested to determine if the micron-sized material has similar positive effects on the resin curing rate.<\/jats:p>","DOI":"10.3390\/polym12071435","type":"journal-article","created":{"date-parts":[[2020,6,30]],"date-time":"2020-06-30T14:24:24Z","timestamp":1593527064000},"page":"1435","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["Potential Use of Wollastonite as a Filler in UF Resin Based Medium-Density Fiberboard (MDF)"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6952-0923","authenticated-orcid":false,"given":"Hamid R.","family":"Taghiyari","sequence":"first","affiliation":[{"name":"Wood Science and Technology Department, Faculty of Materials Engineering &amp; New Technologies, Shahid Rajaee Teacher Training University, Tehran 16788-15811, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8340-7348","authenticated-orcid":false,"given":"Ayoub","family":"Esmailpour","sequence":"additional","affiliation":[{"name":"Department of Physics, Faculty of Sciences, Shahid Rajaee Teacher Training University, Tehran 16788-15811, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8451-3695","authenticated-orcid":false,"given":"Roya","family":"Majidi","sequence":"additional","affiliation":[{"name":"Department of Physics, Faculty of Sciences, Shahid Rajaee Teacher Training University, Tehran 16788-15811, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1524-9138","authenticated-orcid":false,"given":"Jeffrey J.","family":"Morrell","sequence":"additional","affiliation":[{"name":"National Centre for Timber Durability and Design Life, University of the Sunshine Coast, Brisbane, QLD 4102, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammad","family":"Mallaki","sequence":"additional","affiliation":[{"name":"Wood Science and Technology Department, Faculty of Materials Engineering &amp; New Technologies, Shahid Rajaee Teacher Training University, Tehran 16788-15811, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7083-9491","authenticated-orcid":false,"given":"Holger","family":"Militz","sequence":"additional","affiliation":[{"name":"Wood Biology and Wood Products, Georg-August-University G\u00f6ttingen, 37077 G\u00f6ttingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6226-5309","authenticated-orcid":false,"given":"Antonios N.","family":"Papadopoulos","sequence":"additional","affiliation":[{"name":"Laboratory of Wood Chemistry and Technology, Department of Forestry and Natural Environment, International Hellenic University, GR-661 00 Drama, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,6,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Pizzi, A., Papadopoulos, A.N., and Policardi, F.
