Unique Capping Process Enables Cost-Effective Addition of Specialized Properties

Spartech Corporation, a leading producer of engineered plastic sheet, polymeric compounds, and engineered products, will showcase its ROYALITER family of sheet products for medical and dental applications at the SPE Thermoforming Conference 2007, Booth #201.

ROYALITE sheet products for medical applications, available in four standard blends and custom formulations, offer light weight, high heat distortion and anti -microbial characteristics. Most notably, ROYALITE's cap technology provides excellent color control, a desired gloss level, special effects and medical-related additives. This unique process provides the full benefit of the desired requirements without the cost of incorporating them into the substrate.

Brentwood Industries of Reading, Pa., uses ROYALITE R59 sheet with cap technology to pressure-form the exterior covering of a high-tech imaging device used for dental and ear/nose/throat applications. "Our excellent experience with ROYALITE over a number of years prompted us to recommend the R59 sheet to meet our customer's needs for attractive aesthetics and easy cleaning, as well as compliance with UL94 V0 flame retardance standards," said David Fry, Brentwood's sales manager. "The material is prepared by Spartech with a cap incorporating a custom color and a low-gloss finish, which avoids the need for secondary painting. From a processing standpoint, the R59 sheet is easy to form, picks up precise detail, and machines beautifully. We like working with it, and our customer was delighted with the results."

Spartech's unique cap process enables specific properties such as colorants, gloss, textures and special effects to be added to the extruded sheet. Further, because the calendared cap layer is applied after the sheet is extruded, these enhancements are not subjected to potential distortion from the high heat of the extruder. This process ensures lot-to-lot consistency and retention of properties after thermoforming. In addition to capping, ROYALITE sheet can be enhanced with decorative films.

"Our family of ROYALITE materials provides a choice of properties to meet the diverse needs of today's medical devices," said Eric Lattanner, ROYALITE product manager. "Whether it's lighter weight compared to traditional PVC acrylic, or the addition of special capabilities achieved through our proprietary cap process, ROYALITE products make it easy for design engineers to find the best material for their application."

To support customers' application development needs, Spartech offers in-house compounding, an analytical and physical laboratory, and a full research and development staff.

ROYALITE sheet for medical applications is available in four grades: R52 PVC/acrylic; R59 PVC/ABS; R71/920 PC/ABS alloy; and R11/24 GP ABS with an anti-microbial cap layer. ROYALITE materials are widely used in the building and construction industry as well as transportation, electronics, and recreation and leisure.
