Bal Seal Engineering Achieves USP Class VI and ISO 10993-5 Compliance for Medical Sealing Polymers
FOOTHILL RANCH, Calif.--(BUSINESS WIRE)--Mar 12, 2019--Bal Seal Engineering, a leading manufacturer of custom-engineered sealing solutions for medical applications, has achieved USP Class VI compliance for its SP-191 and SP-23 seal materials. It has also achieved ISO 10993-5 compliance for its SP-191, SP-23, and UPC-15 materials.
David Wang, Global Market Manager for Bal Seal Engineering’s medical products, says the achievement validates earlier internal testing, and that it highlights his company’s ability to solve tough challenges requiring seals that can safely interact with the human body.
“These materials have supported some of the world’s most advanced medical applications,” says Wang, “and they’re proven performers for our customers, who subject them to their own rigorous testing. But these latest results give us an unbiased, accurate means to represent their performance and safety.”
The United States Pharmacopeia (USP) tests, which were administered by an independent testing authority, evaluated the potential biological effects of the polymer materials. Bal Seal Engineering’s SP-191 and SP-23 materials passed the Class VI test, which is the most stringent. During the International Organization for Standardization (ISO) 10993-5 test, which measured adverse biological effects of extractibles from medical device materials, SP-191, SP-23, and UPC-15 were tested for biological and cytotoxicity responses. They produced no reaction, confirming they are safe for both direct and indirect contact with the human body.
SP-191 is a filled polytetrafluoroethylene (PTFE) compound, and SP-23 is a high-performance blended polymer with a PTFE base. UPC-15 is an ultra-high molecular weight polyethylene (UHMWPE) material. All three of the materials are frequently employed in the design of the company’s Bal Seal® spring-energized seals, which prevent leakage and protect critical components in powered surgical tools, pumps, catheters, and other medical equipment.
According to Wang, the results will allow designers to confidently incorporate Bal Seal Engineering’s sealing materials into a broader range of medical devices, including short and long-term implantables. As “compliant” materials, he adds, the polymers will also help streamline development.
“What this means,” says Wang, “is that medical OEMs and tier suppliers can feel even better about using our seals to achieve new levels of device performance, reliability, and safety.”
