Silicone Industry
High Quality Products and Personalized Service
CFI helps silicone manufacturers improve formulas and add valuable properties to their products. Customer-reported results of using Austin Black 325 include improved compression set, insulating properties, tint strength, and significant compound cost savings–which means overall better results than with competitor products.
Advantages of End-Product
Improved Compression Set
Austin Black 325 can greatly improve the compression set of silicone products, as shown in a mechanical properties and cost evaluation conducted by ACE Products and Consulting. Customer-reported results include cutting compression set in half when Austin Black 325 was used in place of other materials.
Higher Insulating Properties
Studies show that silicone formulas using Austin Black 325 have dielectric properties that are comparable to formulas containing Min-U-Sil.
Increased Profitability
Thanks to its low specific gravity, Austin Black 325 can fill up to three times as much volumetric space as other mineral fillers, creating more finished product at a significantly lower per pound volume cost. As one of the most cost-effective pigment and mineral fillers available, it has a specific gravity of 1.30. When compared to the specific gravity of Min-U-Sil at 2.65, Austin Black 325 can significantly lower compound costs, ultimately leading to increased profitability.
Improved Efficiency
In addition to adding valuable properties to silicone formulas, Austin Black 325 can help simplify recipes and eliminate unnecessary additives. For example, when manufacturing black colored silicones with Austin Black 325, additional black pigments such as TriColor can be removed while retaining the desired color of the finished product.
What CFI Customers Are Saying:
“With Austin Black 325, we achieved better compression set and lower costs.”

Frequently Asked Questions
How does Austin Black 325 improve silicone performance?
It significantly enhances mechanical durability and flexibility, while also delivering consistent coloration that often allows for dye elimination from formulations.
Why switch to Austin Black 325 instead of conventional fillers?
Its lower specific gravity results in more voluminous usage with lower cost. It also boosts compression resistance, leading to higher product quality and profitability
Can it enhance silicone thermal or electrical properties?
Absolutely. Incorporation of Austin Black 325 improves thermal stability—and certain formulations can boost electrical conductivity when needed
What makes our solution valuable for the silicone industry?
CFI offers consistent high purity, reduced product complexity, and strong support for formulation optimization—all with cost-effective performance.
Is it suitable for outdoor or high-heat silicone?
Yes. It helps silicone withstand environmental stressors like UV exposure and ozone while maintaining structural integrity
What role does carbon black play in silicone formulations?
Carbon black enhances the mechanical strength, UV resistance, and electrical conductivity of silicone products. It’s especially useful in applications like conductive silicone rubber and weather-resistant sealants.
What mechanical benefits do carbon fillers bring to silicone?
They improve compressive strength, tear resistance, and mechanical durability, particularly in high-stress applications like gaskets and seals.
Can carbon black improve thermal stability in silicone products?
Yes, certain grades of carbon black can significantly boost thermal stability in silicone compounds. This makes them ideal for high-temperature applications, including automotive and industrial seals.
Does incorporating carbon require only small amounts?
Yes. Compared to rubber, silicone rubber can achieve enhanced performance with lower filler loadings, especially when using fine, structured carbon black grades.
Is CFI Carbon’s product range suitable for food-grade silicone applications?
While many of CFI’s carbon blacks are tailored for industrial use, some low-impurity grades can be evaluated for food-grade silicone, depending on regulatory requirements and application needs. Please contact our team for specific compliance details.
