Solution for Lightweight Application of Polyurethane Foam Adhesive in Two Wheel Electric Vehicles

Under the rapid development trend of new energy two wheeled electric vehicles, product design is iteratively upgrading towards lighter, safer, and more environmentally friendly directions. Especially in battery pack systems, traditional structural sealant is no longer able to meet the multiple requirements of the new national standard for vehicle quality, flame retardant rating, and cost control. Therefore, polyurethane foam (PUR Foam) has gradually become a key material for the manufacturing of two wheeled electric vehicles due to its advantages of lightweight, flame retardancy, and strong structural support. Solution for Lightweight Application of Polyurethane Foam Adhesive in Two Wheel Electric VehiclesThis article by ELAPLUS will delve into the application of polyurethane foam adhesive in two typical scenarios: “foaming and sealing of battery packs for two wheeled electric vehicles” and “replacement of plastic structural frames”.Application 1: Foam sealing of battery packs – balancing lightweight and safety performanceWith the comprehensive upgrade of safety and energy efficiency standards for electric two wheelers by the country, weight control of battery systems has become an important part of vehicle compliance design. In the old scheme, traditional potting glue is usually used in quantities of over 2kg to ensure the fixation and protection of the battery cells. In the context of the new national standard, the weight must be compressed to within 400g, which puts higher requirements on the density and structural support performance of the sealing material.
