Product Summary

NOBELPLA56679 is a one-component, solvent-free reactive HM PUR adhesive specifically engineered for TWS Bluetooth earphone charging case assembly, particularly for lower outer shell bonding and structural fixation. The material combines rapid green strength development through cooling solidification with subsequent moisture-induced chemical crosslinking, ensuring long-term structural durability.

Its low viscosity (4,000 mPa·s at 110°C) and extended open time of 5–7 minutes enable precise positioning and efficient automated dispensing in high-volume manufacturing environments. With a lap shear strength of 12 MPa (PC-to-PC) and elongation at break exceeding 600%, the adhesive provides an optimal balance of structural strength and flexibility, effectively accommodating mechanical stress and thermal expansion mismatch.

Featuring pressure-sensitive characteristics, strong substrate versatility, and reliable chemical and environmental aging resistance, NOBELPLA56679 delivers a robust and durable bonding solution for compact consumer electronic assemblies.
