End-Product Advantages

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 pigments and mineral fillers available, it has a specific gravity of 1.30. When compared to the specific gravity of carbon blacks at 1.80, and other mineral fillers at 2.60 to 2.90, Austin Black 325 helps manufacturers lower compound costs, which ultimately leads to increased profitability.

Chemical and UV Resistant

The chemical and ultraviolet resistant properties of Austin Black 325 make it an excellent addition to plastic and coating formulas for customers looking to achieve end-product advantages while improving their overall bottom line.

Greater Versatility​

The low tint strength of Austin Black 325 offers greater versatility for use in a variety of color applications, in addition to black. With a tint strength of 11.4 by ASTM D3265, Austin Black 325 has an overall low impact on tinting material black, making it an excellent organic filler for all color applications.

Increased Processability

Austin Black 325 works as a process aid to decrease mixing time of masterbatches. Its small particle size allows it to readily disperse in plastics and rubbers without causing agglomeration or sacrificing the dispersion of other ingredients.

Frequently Asked Questions

It enhances color, provides UV stability, increases material strength, and can add conductivity for specialty plastic applications.

Applications include HDPE, polypropylene, PVC, ABS, and more — used across automotive, electrical, and packaging industries.

Yes, when used according to regulatory guidelines, carbon black is safe for use in a wide variety of plastic products.

Absolutely. Carbon black absorbs UV rays, protecting plastic materials from weathering and extending their service life.

Yes, we work closely with manufacturers to develop carbon black solutions suited to their specific production needs and goals.

Carbon black is a highly effective black pigment that provides deep, rich coloration and uniform dispersion in plastic materials. It helps manufacturers achieve a consistent, jet-black appearance, even at low loading levels. Beyond color, it enhances surface smoothness and gloss, improving the aesthetic and commercial appeal of finished products. This is especially important in packaging, consumer goods, and automotive parts where appearance is a key quality factor.

Choosing the right carbon black for plastics depends on several factors, including the desired end-use application, processing method, and performance requirements. Manufacturers should consider particle size, surface area, structure, and the level of dispersion needed. For example, UV-resistant plastics require a specific type of carbon black, while conductive applications demand specialized grades. At CFI Carbon Products, we offer expert guidance to help you select the ideal solution tailored to your product goals and regulatory requirements.
