Spanish additives maker Tolsa has expanded its ADINS-brand range of flame-retardant additives for polypropylene, PVC, rubber polymer systems and silicones.
"This is the next step in our technology," special additives global sales manager Alberto Francesena said during K 2019. "Our customers demand new solutions."
The new ADINS clay synergists deliver reduced smoke production and improved heat release in PP, PVC and rubber polymer systems, in addition to the existing FR additives used in other polymers. Smoke can be reduced by as much as 50 percent, Francesena said.
Products using the new materials can be found in the wire and cable, construction and electrical/electronic end markets. They were commercialized earlier this year and are made at Tolsa's production site in Madrid, where the firm is based.
Tolsa's expanded product line includes a new grade that uses titanium dioxide to improve the performance of intumescent systems for PP and coatings. This new ADINS clay grade demonstrates further stabilization of the char in intumescent systems, improving the flame retardant efficiency.
Officials added in a news release that Tolsa is focused on translating its unique FR technology to other polymer matrices including nylon, polycarbonate and thermosets.
Francesena added that Tolsa's technology team is working on several new grades that could be commercialized in 2020.
