Arthropod elastin polymers with extremely high resilience

CSIRO has developed a method of production and can connect them with insoluble materials, creating a series of production opportunities.

Arthropod elastin, a protein found in vivo with fleas and ticks, is an energy buffer register.

Dr. Chris Elvin of the CSIRO Research Group on Biomaterials has developed a recombinant structure of the arthropod elastin and developed a method for dissolving this protein in insoluble materials such as rubber.

This made protein rubber has a 98% resilience (or rebound efficiency) - a greater advantage than synthetic polybutadiene rubber, which is the benchmark for the rebound efficiency of synthetic rubber.

A simple photoactive chemical process can dissolve the transiently cross-linked soluble recombinant protein in situ in solid rubber - for example, in differently soluble matrices.

The resulting arthropod elastin polymers have higher strength and resiliency under various shapes and are suitable for various applications.

Market opportunities

The current research direction of rubber is its fatigue life, its compatibility with biological systems, and its cost.

In addition to the re-industrial application, this high-performance bio-rubber has almost no frictional activity and long-life performance, which makes it has broad prospects in medical applications, such as:

Spinal disc skin application of drug delivery for injection of arterial elastin is also being studied in tissue engineering applications.
