WebThe permeability or inverse barrier is an important physical property for many industrial and biomedical applications of polymers. For example, polymers with low permeability, i.e. high barrier properties, are required for food packaging applications to prevent loss of flavor, color and quality and to retard spoilage. Web15. okt 2024 · We’ve analyzed our bottle-sealing waxes with advanced lab testing and determined their drop melting points in the range of 159-180 degrees Fahrenheit. That means the wax will become a liquid, yet it’s not the ideal temperature for dipping. So, what temperature should wax be for the best results?
