Alternative stabilisation Stabilization Technologies, a provider of analytical and additive solutions to the plastics industry, has developed


what it claims is a new stabiliser technology - spectral modifier. The new additive is said to function through a process called plasmonic mechanism. “Historically, the business of light stabilisation has boiled down to absorbance and free radical scavenging absorbance from conventional organic UVA, while hindered amines provide free radical scavenging not absorbance. Both have significant limitations. Issues range from in situ conver- sion to non-absorbing species to causing pro-degradant effects, while the physical-chemical properties of volatility, migration, extraction and chemical interactions compound the cost-performance,” says Dr Joe Webster, President of Stabilization Technologies. “ “Now we have ECHA and REACH limiting hydroxy benzotriazoles from use in plastics, adding to global problems. However, these problems disappear with the introduction of Uvita SME 3811,” he says. The company says its material comes from sustainable green chemical sources and is inexpensive. It claims no volatility issues and no migration or extraction from the polymer matrix. The additive is also said to have a broad spectral absorbance from 200-800nm and absorbs in the near infrared, mid IR thermic region and FIR far
