Effect of Kraft Lignin from Hardwood on Viscoelastic, Thermal, Mechanical and Aging Performance of High Pressure Laminates.
(Waste and Biomass Valorization, 2017-07-10)
In this work, the synthesis and characterization of phenol-formaldehyde resols modified with 10, 20 and 30 wt% of Kraft lignin (a waste from pulp industry) from hardwood were studied. In all cases, the Kraft lignin ...
Synthesis and mechanical properties of laminates based on phenolic resins modified with sodium lignosulfonate.
(Latin American Applied Research, 2017-05-08)
The reduction of phenol and/or formalde-hyde consumption during phenolic resin synthesis is of great technological and scientific interest because of its economic and environmental implications. In this work, the addition ...
Technical lignins modified by hydroxymethylation for the production of decorative laminates: Synthesis, characterization and mathematical modelling
Technical lignins are natural and renewable poly-phenolic polymers obtained mainly as a subproduct from the pulp industry. It presents a complex structure that depends on the wood type and the pulping process adopted to ...
