Application of luminescent pigments in plastics
The main component of luminescent pigments is aluminate. It is a new type of long afterglow luminescent material. Compared with traditional ZnS luminescent materials, their afterglow time after short-term illumination is more than ten times longer. Additionally, they have excellent lightfastness and durability. It is non-toxic and non-radioactive. No toxic chemicals are introduced or produced […]
Understanding Flame Retardancy: Oxygen Index vs. UL94 Ratings
The Oxygen Index (OI) refers to the minimum concentration of oxygen needed for a material to sustain flame combustion in a mixture of oxygen and nitrogen gases under specific conditions. It is expressed as a percentage of oxygen volume. 1. What is the Oxygen Index (LOI)? The Oxygen Index indicates the oxygen concentration required for […]
Barium sulfate flame retardant powder
Barium sulfate flame retardant, known as barium sulfate FR. It is a white powder with small particle size and high hydrophobicity. It is a phosphorus-containing organoaluminum salt flame retardant. It is widely used in engineering plastics like PET, PBT, nylon (including glass fiber reinforced), thin adhesives, flexible epoxy laminates, and TPE (TPEE, TPU, and PEBA). […]
