Published selection guide articles across applications, materials, and technical topics.
In a practical review of ABS·PC/ABS laser marking, comparing product names or supplier representative figures alone is not sufficient. First, the required functions of the final part or film, acceptable appearance and processing range, and actual test conditions must be defined. Then, candidate materials must be compared under the same base material, thickness, process, and conditioning conditions to obtain meaningful conclusions.

Hexagonal Boron Nitride (hBN) is the primary screening material. In a practical review of the comparison between plate-shaped hBN and aggregated hBN, it is not sufficient to compare only the product name or the supplier's representative figures. First, the required functions of the final part or film, acceptable appearance and processing range, and actual test conditions must be defined. Then, candidate materials must be compared under the same base material, thickness, process, and conditioning conditions to obtain meaningful conclusions.

Hexagonal Boron Nitride (hBN) is the primary screening material. Bonghyung Lee hBN Comparison of product names or supplier representative figures alone is not sufficient in a practical review of particle size combination selection. First, the required functions of the final part or film, acceptable appearance and processing range, and actual test conditions must be defined. Then, candidate materials must be compared under the same base material, thickness, process, and conditioning conditions to obtain meaningful conclusions.
A crop- and climate-specific framework for designing NIR control in greenhouse films without treating solar heat reduction and crop-light transmission as the same requirement.
A material-native family guide that separates Bismuth Oxide as the Bi2O3 gateway, alpha/beta/delta phase nodes, Ca-Doped Bismuth Oxide as a modified functional route, and non-Bi2O3 compounds outside the phase selector.
A material-native graphene family map that separates chemical identity, sheet or network architecture, oxidation and defect state, supplied form, functional role, processing risk, first screen, and evidence required.
A formulation and qualification framework for clear PET window-film stacks that reduce transmission over a declared NIR band while controlling visible transmission, haze, color, adhesion, absorbed heat, and durability.
A formulation and qualification framework for transparent NIR-control PVC film that separates flexible and rigid PVC, compares slurry, concentrate, and coating routes, and keeps optical performance tied to plasticizer, stabilizer, migration, processing, mechanics, and aging evidence.
Multi-Walled Carbon Nanotubes (MWCNT), Single-Walled Carbon Nanotubes (SWCNT), Graphene Nanoplatelets (GNP), and Antimony Tin Oxide (ATO) are screening candidates. In a practical review of CNT masterbatch carrier selection for PP·PA·ABS·TPU, comparing product names or supplier representative figures alone is not sufficient. First, the required functions of the final part or film, acceptable appearance and processing range, and actual test conditions must be defined. Then, candidate materials must be compared under the same base material, thickness, process, and conditioning conditions to obtain meaningful conclusions.
Hexagonal Boron Nitride (hBN) is the primary screening material. For a practical review of hBN for silicone gap fillers, comparing product names or representative figures from suppliers alone is not sufficient. First, the required functions of the final part or film, acceptable appearance and processing range, and actual test conditions must be defined. Then, candidate materials must be compared under the same base material, thickness, process, and conditioning conditions to obtain meaningful conclusions.
In a practical review of reliable laser marking of recycled plastics, comparing product names or supplier representative figures alone is not sufficient. First, the required functions of the final part or film, acceptable appearance and processing range, and actual test conditions must be defined. Then, candidate materials must be compared under the same base material, thickness, process, and conditioning conditions to obtain meaningful conclusions.
Candidate controls include copper hydroxy-phosphate (BCHP). Select an additive only after defining tag colour, TPU grade, mark polarity, wavelength, cycle-time target, durability method and restricted-substance boundary; then compare candidates in the same compound and moulded geometry.
How to Select Particle Morphology When Processing Limits Matter as Much as Performance — a method-conditioned engineering guide for Conductive Plastics & Coatings covering structure-function behavior at the material, interface, and finished-system boundary, process limits, validation, and qualification boundaries.
How to Translate Electrical, Thermal, Optical, Mechanical, and Environmental Requirements into a Material Architecture — a method-conditioned engineering guide for ESD Materials covering structure-function behavior at the material, interface, and finished-system boundary, process limits, validation, and qualification boundaries.
In a practical review of laser marking additive selection for PP, comparing product names or supplier representative figures alone is not sufficient. First, the required functions of the final part or film, acceptable appearance and processing range, and actual test conditions must be defined. Then, candidate materials must be compared under the same base material, thickness, process, and conditioning conditions to obtain meaningful conclusions.
Candidate controls include Antimony Tin Oxide (ATO). Qualify flame-retardant plastics as complete formulations because the flame-retardant, synergist, filler and pigment package can dominate laser absorption, colour and decomposition.
