Chest Drainage Units are large devices usually containing several large flat surfaces combined with many intricate pathways. They can be molding nightmares. Fortunately, CYROLITE® compounds' easy and reliable molding characteristics lend themselves to the molding of these difficult parts. Also the welding properties of CYROLITE® allow for the easy mating of parts without the worry of leaks. CYROLITE® is also resistant to PVC plasticizers which means that PVC tubing can be used without problems. Since CYROLITE® compound is clear and tough, its use in chest drainage products helps Heathcare Workers monitor the fluids flowing into the unit, and the durability of the units helps against the abuse that they can be subjected to.
