Development of Cost‐Effective and Highly Transparent Melamine Formaldehyde Resin Modified With Sodium Chloride for Enhancing Glossiness and Abrasion Resistance of Melamine Impregnated Paper

Polymer Engineering &Science, EarlyView.
An eco‐friendly melamine‐formaldehyde was produced by the addition of sodium chloride as a modifier. Modified MF resin improved surface gloss and abrasion resistance of decorative paper and decreased the formaldehyde emission. Curing time of the MF resin decreased with the addition of sodium chloride.

Investigation of Crystal Structure Change and Mechanical Properties of 3D Printed PLA After Annealing

Polymer Engineering &Science, EarlyView.
Thermal annealing of FDM‐printed PLA significantly enhances longitudinal tensile and flexural strengths by increasing crystallinity to 46.6%. However, transverse properties remain constrained by weak interlayer adhesion, providing crucial insights into the anisotropic thermo‐mechanical behavior of printed biopolymers for demanding engineering ...
