SSP2390-30D is a translucent platinum-cured silicone elastomer manufactured by Specialty Silicone Products, Inc. (SSP), supplied platinum pre-catalyzed and ready for immediate use. The 30D grade has a Shore A durometer of 30, positioning it in the soft-mid range of the SSP2390 Series. Tensile strength of 950 psi reflects a meaningful step up from the softer grades, with elongation of 890% maintaining strong deformation tolerance.
Tear strength (Die B) of 150 ppi continues the upward trend across the durometer range. The 30D grade is well-suited for general-purpose soft-mid silicone applications where balanced mechanical performance is preferred over extreme conformability or high stiffness.
Available as a ready-to-mold compound or as compression-molded sheet stock or roll stock, in a translucent base or red, black, gray, and white standard colors. Custom Pantone matching is available with the caveat that pigments require separate USP Class VI testing per color by the end user. Cure profile is 10 minutes at 177°C (350°F) compression cure. Compound shelf life is 6 months (cold storage may extend); cured product shelf life is 15 years.
Compliant with FDA 21 CFR § 177.2600 (Food Contact, Dry & Fatty Foods), USP Class VI (Biocompatibility), and RoHS.
What differentiates SSP2390-30D from other grades in the SSP2390 Series?
30D sits in the soft-mid position at Shore A 30, with tensile strength (950 psi) and tear strength (150 ppi) representing a useful step up from the softer 10D and 20D grades while maintaining 890% elongation. Select 30D when general-purpose silicone elastomer performance is needed without committing to either the soft conformability of 10D/20D or the firmer 40D and above.
Why is durometer selection important when specifying SSP2390-30D?
Durometer determines stiffness, sealing pressure capability, and dimensional stability. At Shore A 30, the 30D grade is the soft-mid range of the SSP2390 Series — appropriate when the application calls for this specific stiffness range. For softer service consider lower-numbered grades (10D / 20D / 30D); for firmer service consider higher-numbered grades (60D / 70D / 80D).
What is the operating temperature range for SSP2390-30D?
The TDS does not publish a service temperature range. Cure profile is specified at 177°C (350°F). Specifiers requiring service temperature data should contact SSP directly.
Is SSP2390-30D suitable for medical device, food-contact, or RoHS-regulated applications?
Yes. The base material meets USP Class VI biocompatibility requirements and FDA 21 CFR § 177.2600 food-contact requirements (dry and fatty foods), and is RoHS compliant. Caveat per the TDS: pigments used in custom Pantone colors require separate USP Class VI testing per color by the end user.
How should SSP2390-30D be specified?
Specify product (SSP2390-30D), color (translucent base / red / black / gray / white / custom Pantone with separate USP Class VI testing per color), supply format (ready-to-mold compound / sheet stock / roll stock / converted die-cut), compliance requirements (FDA 21 CFR § 177.2600 / USP Class VI / RoHS as applicable), dimensional tolerances, and finished format.
