A flexible, liquid covering called liquid rubber solidifies into a robust, waterproof membrane. Synthetic rubber refers to any artificial elastomer. Unless the synthetic rubber is revealed as a polysulfide rubber, laminates including such a layer will be categorised with extra polymers since synthetic rubber is often created from additional polymers of polyene monomers.
A polyurethane in its liquid condition, liquid synthetic rubber has improved flow characteristics and greater abrasion resistance. The production of industrial rubber, tyres, modified polymers, and adhesives are its main areas of use.
The Global liquid synthetic rubber market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Liquid guayule natural rubber, a renewable and crosslinkable processing aid in natural and synthetic rubber compounds.
In natural rubber (Hevea and guayule rubber) and synthetic rubber (styrene-butadiene) composites filled with carbon black (CB), liquid guayule natural rubber (LGNR) was produced by thermal degradation of guayule natural rubber and tested as a renewable substitute for naphthenic oil (NO). Rubber additives called processing oils are frequently used to increase a compound’s processability.
The majority of processing oils, including NO, are derived from petroleum and have a detrimental effect on the carbon footprint of the rubber sector. These aids also serve as diluents, which reduce the mechanical performance of the final rubber products.
Characteristics of natural and synthetic rubber composites created with LGNR included crosslinking networks, mechanical qualities, and rubber compounding’s energy consumption.
By using 13-21% less energy than compounds combined without processing aids, LGNR successfully aided the compounds’ mixing. Furthermore, LGNR served as an active additive in the vulcanization reaction, in contrast to NO.
When NO was substituted for LGNR in the compounds, the tensile strength, elongation at break, modulus at 100% strain, and hardness all increased.
Strong LGNR-CB interactions and extra crosslinking networks created between LGNR and the rubber matrices may be the causes of the improved mechanical qualities. As a renewable processing aid, LGNR may help rubber goods meet their increasing performance targets and lower their carbon impact.
In conclusion, LGNR improves the characteristics of the finished material, offers the same advantages as traditional diluent processing aids, and is made from a renewable plant source.
