Hollow Microsphere & Specialty Chemicals for Oil and Gas Manufacturer in India

PETRA Cenosphere (FILLIT) is a lightweight hollow alumino-silicate microsphere derived from coal-fired power plants and engineered for high-performance industrial applications. These inert, free-flowing hollow spheres offer an exceptional combination of low density, high compressive strength, thermal insulation, and chemical resistance. PETRA FILLIT acts as a multifunctional filler that reduces product weight, lowers resin and binder consumption, improves flowability, and enhances dimensional stability. Its spherical structure functions like microscopic ball bearings, improving workability while minimizing shrinkage and warpage. PETRA Cenosphere is widely used in oil & gas cementing, paints & coatings, construction materials, composites, refractories, friction materials, and insulation applications. Available Grades: FILLIT 0.80 H, FILLIT 0.80 M, FILLIT 0.80 L, FILLIT 0.85 H, FILLIT 0.85 M, FILLIT 0.85 L, FILLIT 75, FILLIT 100, FILLIT 125, FILLIT 150, FILLIT 212, FILLIT 300, FILLIT 500, and FILLIT 500 EX.

PETRA Microlite (Hollow Glass Microspheres) is a premium-grade lightweight filler engineered from hollow soda-lime borosilicate glass microspheres. Designed for high-performance industrial applications, Microlite offers an exceptional strength-to-weight ratio, low density, thermal insulation, and chemical resistance. Its smooth spherical structure improves flowability, reduces shrinkage, lowers resin and binder consumption, and enhances overall product performance. PETRA Microlite is widely used in oil & gas, automotive, aerospace, construction, composites, paints, coatings, adhesives, and insulation applications where weight reduction and performance enhancement are critical.

PETRA Expanded Microspheres (EXP Series) are advanced lightweight inorganic mineral microspheres engineered to deliver superior weight reduction, thermal insulation, and formulation efficiency across a wide range of industrial applications. Manufactured using advanced expansion technology, these microspheres feature a closed-cell structure that provides low density, high thermal stability, excellent flowability, and dimensional stability. PETRA EXP Series helps reduce material consumption, improve workability, enhance insulation performance, and optimize processing efficiency. These versatile lightweight fillers are widely used in dry-mix mortars, construction chemicals, plasters, putties, coatings, polymer compounds, composites, insulation systems, and other industrial applications requiring lightweight and high-performance formulations.
