Knowde Enhanced TDS

Identification & Functionality

Features & Benefits

Materials Features: Improved Adhesion
Product Highlights: The use of multi-layered films and tubing is commonplace and established in the medical device, pharmaceutical, and packaging industries. Multi-layer construction can be used to target various barrier properties, extending packaging shelf life, or to impose different functionalities in catheter tubing. Each layer is optimized for maximum functionality; thus, the various layers may contain very different chemical structures. Materials with different chemical structures often result in sub-optimal adhesion and delamination when co-extruded directly. Therefore, tie-layer plastic resins are used to bond these dissimilar materials.

ReZilok Rx 101 Tie-Layer Resin is linear low-density polyethylene (LLDPE) grafted with maleic anhydride. ReZilok is manufactured with the stringent quality required by the biomedical industry in accordance with the ISO 13485:2016 standard. Due to the polarity and reactivity of maleic anhydride, ReZilok Rx 101 can be used as a tie-layer in the production of multi-layer co-extruded catheter tubing to bond dissimilar materials.

Additional Process Considerations: A variety of factors can influence the adhesion performance of ReZilok Rx 101 tie-layer resin. Adhesion is generally improved by increasing the melt temperature, the duration of interlayer contact in the melt state, and the interlayer contact pressure

Purging An LLDPE resin (or secondly an LDPE) is recommended for purging prior to or after extrusion of ReZilok Rx 101. To prevent gel or char formation, it is recommended to maintain a slow throughput while the line is sitting idle with ReZilok Rx 101 in the barrel.

Technical Details & Test Data

Drying Requirements: In order to ensure maximum adhesion performance and extrusion surface quality, it is recommended to dry ReZilok Rx 101 at 160°F until moisture content is below 0.05%. Polyethylene does not typically require drying; however, the grafted maleic anhydride in ReZilok Rx 101 is susceptible to hydrolysis which can render the tielayer less effective for chemical and physical bonding. In thin walled applications, drying ReZilok Rx 101 removes any potential pellet surface moisture which could influence final product surface esthetics.

Storage & Handling

Handling: ReZilok Rx resins are supplied as free-flowing pellets. In general, Rezilok can be handled similar to standard polyethylene polymers. A Safety Data Sheet for ReZilok Rx resins should be consulted for other detailed guidelines.
Storage Conditions: Typical shelf life of ReZilok Rx 101 is two years from date of delivery in unopened packaging. When not being used, the container and liner should be closed and stored in a cool dry area protected from UV light.
