Revolutionizing Flexible Medical Device Assembly with Advanced Light Cure Adhesives
As regulatory pressures increase on PVC-containing medical devices due to DEHP restrictions, the demand for reliable bonding solutions on flexible substrates such as thermoplastic elastomers (TPEs) has become critical. Henkel introduces Loctite AA 3952 and Loctite SI 5057, two cutting-edge light cure adhesives engineered to overcome the inherent challenges of TPE assembly while meeting stringent EU MDR 2017 and FDA safety standards.
✨ Market Trends
The medical device industry is rapidly transitioning from traditional PVC-based materials to biocompatible alternatives like TPEs. This shift necessitates adhesives that can maintain mechanical integrity, resist thermal and humidity aging, and ensure patient safety in regulatory-compliant manufacturing.
✨ Applications
These adhesives are ideal for bonding flexible medical devices, including catheters, tubing assemblies, wearable sensors, and other patient-contact components. Their compatibility with TPE-S and TPE-O substrates enables secure, durable assembly where conventional solvent welding or standard adhesives fail.
✨ Highlights
- High-performance adhesion: Reliable bonding to challenging TPE surfaces.
- Environmental resilience: Maintains structural integrity under heat and humidity stress.
- Regulatory compliance: ISO 10993 biocompatibility tested; free from CMR and endocrine-disrupting substances.
- Process efficiency: Optimized for light cure processing, reducing energy consumption and assembly time.
✨ Product Advantages
Loctite AA 3952 and SI 5057 combine chemistry-driven innovation with precision engineering to ensure medical devices are both safe and durable. Their advanced photopolymerization mechanisms allow deep cure and rapid assembly, while maintaining regulatory compliance and biocompatibility. By enhancing substrate versatility and assembly efficiency, these adhesives empower medical manufacturers to meet evolving patient safety demands and technological advancements.
