NOBELPLA56081 – HM PUR Adhesive for Tablet PC Metal Part Bonding

Product Summary

NOBELPLA56081 is a high-performance Hot Melt Polyurethane (HM PUR) reactive adhesive developed for tablet PC structural assembly and metal component bonding. The material features a dual-stage curing mechanism: rapid green strength development through cooling solidification, followed by moisture-activated chemical crosslinking to achieve long-term structural integrity.

With a lap shear strength of 15.6 MPa (PC-to-PC), the adhesive delivers robust structural bonding performance. Its exceptional elongation at break (1,014%) provides excellent flexibility and stress accommodation, making it suitable for thin and lightweight electronic assemblies subject to thermal expansion and mechanical loading.

The controlled viscosity of 9,250 mPa·s at 110°C and a 2–4 minute open time enable precise application in automated production lines. Combined with strong chemical and environmental aging resistance, NOBELPLA56081 offers a reliable and durable bonding solution for advanced consumer electronic devices.
