Introduction

Selecting the best adhesive technology to satisfy performance criteria for the medical industry can be a difficult task for a needle manufacturer, especially when performance really counts! They must understand that performance of the adhesive is crucial when joining the stainless steel cannula to the plastic hub to form the bonded needle. The critical component to holding these two very different substrates together is a specialty adhesive designed to ensure the cannula remains adhered to the hub and functions correctly during use. By using specialty adhesives, the needle manufacturer will ensure the needle will not separate from the hub, leak or fail under typical conditions encountered in the medical industry.

• Engineered Materials Systems, Inc, or EMS, designs custom needle bonding adhesives for medical needle producers. EMS works directly with the customer to supply them with adhesives that will not only meet but exceed their performance requirements.

• It is important that EMS develop adhesives under ISO and USP guidelines while ensuring the customer’s needs are optimized to the best of EMS’s ability. EMS understands the lengthy qualification process needle manufacturers must put new adhesives through to ensure their performance requirements are met.
