BISCO® MS-1630 is the softest grade in the MS-16 series at 30 Shore A, formulated specifically for life science applications requiring maximum compliance and conformability. It is produced from a low volatile, peroxide-free, platinum-cured silicone compound, yielding a non-toxic and chemically inert cured product suited for direct contact with medical devices, bio-pharmaceutical equipment, and health tech assemblies. The glossy smooth surface finish supports hygienic cleaning and sealing performance in precision life science environments.
The 6% compression set (70 hours @ 212°F @ 25% deflection) is the lowest in the MS-16 series, indicating excellent elastic recovery and long-term sealing integrity under sustained load. At 725% elongation, this grade is highly flexible and readily processed by die-cutting into precision gasket, seal, and fluid control profiles.
Compliant with USP Class 6 / 21CFR177.2600 — Compliant.
What differentiates BISCO® MS-1630 from higher-durometer grades in the MS-16 series?
BISCO® MS-1630 is the softest grade in the MS-16 series at 30 Shore A and achieves the lowest compression set in the series at 6% (70 hours @ 212°F @ 25% deflection). This combination of maximum compliance and exceptional elastic recovery makes it the preferred choice for life science sealing applications where conformability and long-term sealing force retention under low closure loads are critical.
Why is compression set an important consideration for solid silicone elastomers in medical and life science applications?
Compression set measures how well an elastomer recovers its original thickness after sustained compression. In medical device gaskets and seals, a material with high compression set will permanently deform over time, degrading the seal and potentially compromising sterility or fluid containment. BISCO® MS-1630 achieves 6% compression set (70 hours @ 212°F @ 25% deflection per ASTM D395), indicating strong elastic recovery suited for long-term sealing performance in regulated environments.
What is the temperature range for BISCO® MS-1630?
BISCO® MS-1630 is rated for service from -80°F to 450°F, as listed on the TDS.
Is BISCO® MS-1630 suitable for medical device and regulated life science environments?
Yes. BISCO® MS-1630 is compliant with USP Class 6 and 21 CFR 177.2600, and is produced from a low volatile, peroxide-free, platinum-cured raw material providing a non-toxic and chemically inert cured product, as stated on the TDS.
How should BISCO® MS-1630 be specified?
Specify grade (BISCO® MS-1630), thickness, compliance requirements (USP Class 6 / 21CFR177.2600), dimensional tolerances, and finished format.
