N-10 Grade: The Fine Filtration Specialist
PURPOSE:
The N-10 grade stands as our premier choice for fine filtration needs, particularly excelling in rotary vacuums or filter presses. Its exceptionally small and shattered particles are tailored for intricate applications that demand high precision in separating solids from liquids.
EFFECTIVENESS:
N-10’s fine particles construct a formidable cake layer, transferring the filtration workload from the septum to the perlite filter aid itself. This transition allows for efficient trapping of solids while facilitating the clean passage of liquids. In rotary vacuums, it ensures that solids are effectively separated, leaving behind a clear, purified liquid.
N-20 Grade: The Coarse Clarity Provider
PURPOSE:
As our coarsest filter media, N-20 is predominantly used in filter presses, especially for wastewater applications. This grade is known for its economical value without compromising on performance.
EFFECTIVENESS:
N-20 utilizes its coarser particles to adeptly facilitate the separation process in filter presses. Its structural integrity allows for a pronounced separation of solids and liquids, resulting in clear filtrate and effective solid retention.
N-30: The Dynamic Absorbent
PURPOSE:
N-30 is your go-to solution for effectively solidifying a broad spectrum of spills, ensuring easy and safe disposal. It’s the preferred choice for sludge solidification across various sectors, including water districts and refineries.
EFFECTIVENESS:
Thanks to its porous structure, N-30 boasts an impressive ability to absorb 3-5 times its weight in liquids. The varied particle sizes (8 to 200 mesh) enhance its absorption efficiency, making it a robust and reliable choice.
N-40: The Pool Base and Cement Enhancer
PURPOSE:
Building on the strengths of N-30, N-40 offers a larger particle size, making it ideal for pool bases and cement mixes. It’s designed to integrate seamlessly into your projects, providing a lighter, more insulative finish.
EFFECTIVENESS:
N-40’s larger particles (6-12 mesh) are optimized for mixing with cement, typically at a 4 to 1 ratio. This creates a lighter product that doesn’t compromise on strength or insulation.
N-50: The Cryogenic and Plaster Pro
PURPOSE:
N-50 is designed as a specialized cryogenic/plaster aggregate grade. This dual-purpose grade functions effectively both as an absorbent and a filler, with a precise 30/50 mesh grade tailored for specific applications.
EFFECTIVENESS:
N-50 is a testament to versatility, combining lightweight properties, insulation, and absorbency. Its multifaceted nature makes it suitable for a wide array of uses, ensuring efficiency and quality in every application.

Industrial Grade Perlite Frequently Asked Questions
Industrial perlite is a lightweight, non-combustible mineral used to improve thermal performance, safety, and efficiency in building insulation, fireproofing assemblies, and cryogenic systems for liquefied gases. Its thermal properties reduce heat transfer, helping maintain interior temperatures and protect structures.
Select silicone‑treated grades when moisture resistance is critical or when assemblies face intermittent wet conditions. Norcal Perlite’s SP100 and SP16 enhance insulation integrity in demanding environments and are used in applications like fire‑rated door cores and wall partitions where both durability and moisture control matter.
Norcal Perlite offers a full range of grades to match performance needs. N10 and N20 are associated with finer versus coarser media needs, N30 is commonly used as an absorbent, N40 supports lightweight concrete and pool‑base mixes, and N50 is suited for cryogenic and plaster applications.
For complex builds or multi layer systems, our team can guide you to the optimum grade. Our experts will review your specifications and provide a tailored grade recommendation with supporting data sheets and submittal details.
Yes. Perlite is non flammable and serves as an effective fireproofing component in construction, helping increase fire resistance in walls and other assemblies while maintaining low weight. Its stable, cellular structure helps slow heat transfer at elevated temperatures, making industrial perlite a strong option for assemblies that must meet stringent fire rating requirements in commercial, industrial, and infrastructure projects.
Perlite provides excellent insulation at extremely low temperatures, limiting heat gain in storage and transport systems for liquefied gases. Because the material remains dimensionally stable under severe thermal cycling, it is frequently specified as loose fill or jacket insulation around tanks and piping that handle LNG, liquid oxygen, and other refrigerated media.
Yes. We host downloadable perlite spec sheets for multiple grades as well as MSDS and related resources, so engineers and buyers can verify performance data and compliance details during design and procurement. Having these documents available online helps design teams streamline submittals, align with internal EHS standards, and quickly compare our perlite to alternative insulation, aggregate, or absorbent materials.
