In contrast to soluble sulfur, the insoluble sulfur is a serrated long-chain structure, also known as μ-sulfur, which has the viscoelastic properties of ordinary polymers. As long as the mixing temperature reaches its glass transition temperature, the μ-sulfur is converted from solid to plastic. It is Plasticized rubber nena inmil awlsam.
