Formula: LDPE
Form: Powder
Material: Low Density Polyethylene (LDPE)
CAS Number: 9002-88-4
Commodity: Polymers
Color:
Natural
Low-density polyethylene (LDPE) powder is widely used in scientific applications beyond traditional manufacturing. Researchers utilize it in polymer blending studies to improve material properties for medical devices, packaging, and biocompatible coatings. It is also applied in environmental testing for microbial degradation research, exploring how plasma-activated microbes like Bacillus safensis can accelerate LDPE decomposition. Additionally, LDPE powder contributes to advancements in nanocomposite development for enhanced barrier properties and is used in fuel cell technology, where LDPE membranes improve proton conductivity, making it valuable for both material science and environmental sustainability research.
