Upcycled polybutylene terephthalate (PBT) resin with slender-wall, non-brominated/non-chlorinated flame retardance (FR) has been added to Sabic’s portfolio of iQ compounds. LNP Elcrin WF0051iQ is suited for the fabrication of miniaturized electrical parts as nicely as vital professional medical gadgets and equipment programs, according to Sabic.
The petrochemicals big dependent in Riyadh, Saudi Arabia, claimed that the new grade will enhance its now major diversion of write-up-client polyethylene terephthalate (PET) water bottles, which are chemically upcycled into PBT resin. At the close of 2022, the enterprise claimed it had presently diverted 400 million fifty percent-liter bottles by means of its iQ upcycling engineering.
Minimized carbon footprint
LNP Elcrin WF0051iQ has an 11% smaller carbon footprint than conventional, fossil-based virgin PBT resin, according to Sabic, because each and every kilogram of materials includes 39 recycled fifty percent-liter PET water bottles, symbolizing at the very least 27% of the information. Also, SCS Worldwide Expert services has audited and delivered independent verification that the producing procedures for LNP Elcrin iQ compounded resins adhere to the SCS Recycled Written content Common, and that the provide chain satisfies criteria for responsible sourcing.
The means to style skinny partitions also adds to the compound’s sustainability positive aspects, and the FR formulation will help keep away from the use of bromine and chlorine, two semi-risky organic and natural compounds that are connected to health and fitness and environmental hazards, explained Sabic.
The combination of slim-wall FR, prolonged-term assets retention, and glass-fiber reinforcement for stiffness together with superior move to help elaborate geometries helps make LNP Elcrin WF0051iQ very well suited for miniaturized electrical elements this sort of as connectors, switches, and sockets.
Resin meets UL94 V0 typical for hearth resistance
The new resin is the initially LNP Elcrin iQ compound to satisfy the UL94 V0 standard for hearth resistance at .4 mm and has been given a Yellow Card listing below the UL Plastics Recognition Plan for the signature sustainability green coloration. The material’s relative thermal index (RTI) is 130°C at .4 mm, and the comparative monitoring index (CTI) is 2, contributing to safety and decreased product prerequisites that can reduced the value of tooling and accelerate time to sector, according to Sabic. In phrases of processing, the material’s large flow and minimal abrasion qualities guidance quick throughput in contrast with solutions.
