Degradable Bio-Based Polyester Elastomer

Rubber plays a very important role in our daily life, however all synthetic rubbers currently rely on petroleum resources and are not degradab.

Synthetic rubber depends on imports and sustainable development is a hot spot

Rubber material has the unique characteristics of softness, large deformation and resilien.

The current synthetic rubber varieties include ethylene-propylene rubber, styrene-butadiene rubber, nitrile rubber, cis-butadiene rubber, acrylate rubber, silicone rubber, e.

In addition, synthetic rubber materials are obtained from fossil resourc.

Research and development of bio-based polyester elastomers to carry out demonstration production line construction

In order to realize the sustainable development of the rubber industry and develop the original rubber varieties in China, the Elastomer Center of Beijing University of Chemical Technology proposed in 2008 to use different bio-based diacids and diols as monomers and adopt the method of melt polycondensation to obtain A range of bio-based polyester elastome.

Through more than ten years of unremitting efforts, the Elastomer Center of Beijing University of Chemical Technology has synthesized dozens of bio-based polyester elastomers, and developed their industrialization and applicati.

A variety of rubbers can replace degradable rubber and are expected to be mass-produced

Bio-based polyester elastomer has strong polarity, so it has excellent oil resistance, and can replace nitrile rubber and acrylate rubber in the field of oil-resistant sea.

It is reported that the price of nitrile rubber is 20,000 yuan per ton, and the price of acrylate rubber is close to 100,000 yuan, and it needs to be imported from abro.

Plastics such as polylactic acid and polybutylene succinate have poor toughness and need to be toughened by introducing a toughening age.

China's annual output of polyvinyl chloride (PVC) exceeds 20 million tons, and its plasticizer consumption also exceeds several million to.

In addition, using the degradable properties and non-toxicity of polyester elastomers, the research team designed and synthesized a chewing gum base, and developed a chewing gum that can be degraded in the human body and in the soil, so as to avoid the situation that the chewing gum is spit on the ground and difficult to cle.
