MIL-L-021260 is also known as Dibutyl Sebacate (DBS). It is a colorless liquid with a faint odor, and is primarily used as a lubricant and plasticizer in the rubber and plastics industries. The chemical is also used as a solvent for greases, waxes and resins.
When rubber is exposed to MIL-L-021260, accelerated aging and properties degradation can occur. This can lead to a decrease in tensile strength, elongation, and hardness of the rubber. Additionally, swelling and shrinkage of the rubber may result in cracking and loss of adhesion. In some cases, this chemical can react with the rubber, forming a layer of coating that can reduce the flexibility of the rubber.
