High Uniformity, Low Temperature 360 degree
Bonding & Coating Of Polyethylene Tubing
With Pulsed UV Curing

Standard RC-500C Pulsed UV Curing System

Polyethylene tubing is a widely used material in the Medical Device Manufacturing Industry.  Various applications require 360 degree curing for coating and bonding. This must be done with medical grade formulations, at relatively low temperature and high uniformity. Further, because this is a medical device application, there are typically very stringent requirements for testing the final cured bond strength and completeness of cure.

Xenon Corporation engineers have developed a 360 degree system that meets all of the stringent requirements of these applications. In a typical configuration the RC-5OOC Pulsed UV Curing System, illustrated above, consists of:

• A 300 Watt power supply/controller, including timer(0. 1 to 99.9 seconds in O. 1 sec increments) and remote triggering capability.
• A 47 mm diameter circular pulsed UV lamp for uniform 360 degree curing and high UV output with spectral parameters appropriate for the specific application.
• A complete lamp housing with self-contained cooling, light shielding and an external fitting for nitrogen purge capability or additional cooling in the product environment.

This system, when used with any UV Class 6 FDA Approved adhesive, typically produces fully cured bonds at low temperatures in seconds. Consult the factory for recommendation of a specific formulation and optional lamp configurations.

The RC-5OOC Pulsed UV Curing System has also been used very successfully for curing and bonding to PVC and latex.
