To provide electrical device and connector manufacturers with a lower-cost alternative to traditional materials like thermosets or special high heat polymers, Sabic Innovative Plastics announced its new Xtreme LNP Starflam specialty compounds.
“These polyamide (PA)-based materials can reduce system costs by up to 20 per cent vs thermosets via increased production yields and decreased moulding cycle times,” a company statement said.
“The new Xtreme LNP Starflam compounds, including halogen-free flame retardant (FR) grades, are ideal for demanding electrical applications such as contactors and circuit protection equipment. This technology can offer a solution for the high temperatures encountered in the lead-free soldering processes that the electrical and electronics industry is forced to use under the RoHS directive. Sabic Innovative Plastics’ investment in new high-performance and eco-responsible materials enables the company to help customers optimise application development.
”In a mature industry driven by globalisation and strong competition, system costs are a major point of interest. In high-heat environments like arch quenching or lead-free soldering, producers are usually forced to use thermosets with their higher processing (moulding) costs or more expensive high heat materials. Xtreme LNP Starflam PA’s can be an excellent lower cost alternative in these kinds of applications.”
Arthur van Dijk, electrical and lighting industry manager, Sabic Innovative Plastics, commented: “The Xtreme LNP Starflam compounds combine the typical advantages with regards to easy processing and good electrical and mechanical properties of polyamide with the short-term heat performance of high heat polymers and thermosets at lower costs. Better production yields, like being able to regrind the sprue and the more stable and faster moulding cycle times more than make up for the added costs of the E-beam radiation step that is required after moulding to boost the heat performance.”
The Xtreme LNP Starflam compounds are based on a technology that forms chemical bonds between the PA macromolecules under E-beam radiation. After irradiation the material is able to withstand exposure to temperatures decades higher than standard PA. Where a standard PA would melt or deform, Xtreme LNP Starflam maintains its rigidity and mechanical integrity.
