  • Why do we need plasticizers in NBR?
  • ... Hence, it is necessary to add plasticizers to reduce the viscosity and improve its processability . The plasticizers commonly used in NBR are mainly phthalate esters, which contain ester bonds that can form hydrogen bonds with the cyano groups in the NBR molecule to make plasticizers; thus, offering the copolymer good compatibility .
  • Do bio-based plasticizers affect acrylonitrile-butadiene rubber properties?
  • In this paper, two modified bio-based plasticizers (epoxidized esters of glycerol formal from soybean and canola oil) are of main interest. The study aimed to determine the influence of these sustainable plasticizers on the properties of acrylonitrile-butadiene rubber (NBR).
  • Can bio-based plasticizers be used in the compounding of NBR vulcanizates?
  • 4. Conclusions The use of bio-based plasticizers (EESO, EECO), a conventional plasticizer (TDAE), and a synthetic plasticizer (Mesamoll ®) in the compounding of NBR vulcanizates were studied. It was shown that bio-based plasticizers can advantageously be used as processing aids instead of conventional oils.
  • How do plasticizer-loaded NBR vulcanizates decompose?
  • Generally, these plasticizer-loaded NBR vulcanizates show 3 main decomposition steps. Initially, the plasticizer and all other low-molecular components are decomposed up to ca. 350 °C. Then, the polymer is thermally decomposed in the range of 360–500 °C. According to [ 41 ], the initial decomposition of CB-reinforced NBR starts from 360 °C.
  • Are NBR elastomers compatible with plasticizers?
  • Two types of NBR with different ratios of monomers formed the polymeric basis of the prepared elastomers. The variation of the monomer ratio results in different polarities, and therefore, compatibility between the NBR and plasticizers should be influenced. The mechanical characteristics were investigated.
  • Does plasticizer content affect the tear strength of NBR vulcanizates?
  • Variation of strain at the break with plasticizer content for NBR vulcanizates. The tear strength values (see Figure 6) show a significant increase in the case of bio-based plasticizers, especially at higher plasticizer loading. In the case of TDAE and Mesamoll ®, the tear strength remains almost constant at around 8 N/mm.
