Innovative plastics create sustainable insulation

Written by: Chris Shaw | Published:

Through co-development efforts with SABIC Innovative Plastics, Japan's Nissei Eco Company Ltd. has created a unique solution to significantly reduce the environmental impact of wire harness insulation. That solution is ECO-01 tubing, a wire insulation product made from SABIC Innovative Plastics' Flexible Noryl resin.

This high-tech resin is inherently flame retardant (FR) and free of environmentally harmful heavy metals. It also provides OEMs of home appliances and other products with high heat performance without expensive secondary operations.

Flexible Noryl resin for wire insulation offers OEMs a significantly better material choice vs. traditional polyvinyl chloride (PVC), which contains halogen chlorine. Not only is Flexible Noryl resin non-halogenated to help customers meet global environmental requirements, but the FR material also surpasses PVC in wear resistance. As measured by the JASO-D-608-92 abrasion test, Nissei Eco found that Flexible Noryl resin has much higher abrasion resistance than that of PVC.

Further, Flexible Noryl resin surpasses other non-halogenated materials such as flame-retardant polyethylene (PE) in terms of affordability and processing ease. Because Flexible Noryl resin delivers high-temperature performance and can meet the requirements of UL105C, it does not require cross linking using electron beam radiation – a process that is necessary for flame-retardant PE. Cross linking adds time and cost, and also makes the material stiffer and harder to process.
