Petra Industries Pvt. Ltd. supplies glass microspheres manufactured from soda‑lime borosilicate glass. The product has a true density ranging from 0.20 to 0.60 g/cm³ and a particle size distribution of 2 to 130 µm as stated in the supplier data. These hollow spheres are engineered to deliver a high strength‑to‑density ratio for demanding industrial uses.
In the composites market the material is offered in several crush‑strength grades, allowing formulators to balance load‑bearing capacity with weight reduction. Typical industry grades for glass microspheres fall between 0.15 and 0.60 g/cm³ and exhibit a smooth, non‑porous surface that improves flow in polymer melts. The spherical geometry also reduces viscosity and shrinkage compared with irregular fillers. Standard practice groups particles into fine (≤10 µm), medium (10‑50 µm) and coarse (50‑130 µm) classes, which Petra can customise on request.
Buyers such as automotive lightweighting engineers, marine buoyancy manufacturers and construction composite producers commonly request bulk bag or drum packaging. Petra lists no minimum order in the public data, so importers should confirm the MOQ, Incoterms and payment schedule directly with the company. The supplier’s harbour trust tier indicates a verified business, but response metrics are currently unavailable, so follow‑up communication is advised. Shipping is typically arranged from the Ahmedabad port, with lead times dependent on order size and customs clearance.

Petra Industries Pvt. Ltd. is located at 1107/1108 One World West, Bopal Ambli T‑junction, S.p.ring Road, Ahmedabad, Gujarat 380058, India. The company is listed under the harbour trust tier, indicating that its business credentials have been verified, although the public response rate is currently zero and average response hours are not recorded. Petra’s listing highlights the production of engineered glass microspheres for a range of industrial applications, but does not disclose production capacity, annual turnover or specific client references.
The supplier’s profile states that it offers custom specifications for hollow glass bubbles, focusing on strength‑to‑density performance, chemical inertness and water resistance. No explicit information on certifications, MOQ, lead‑time or payment terms is provided, so interested buyers should contact Petra directly to obtain those details and to request samples or test reports.
Glass Microspheres (Glass Bubbles) are engineered hollow spheres manufactured from soda-lime borosilicate glass, designed to provide exceptional strength-to-density ratios for demanding industrial applications. These lightweight hollow glass spheres are widely used as functional fillers in polymer composites, construction materials, automotive parts, and deepwater buoyancy modules. Available in various size ranges and crush strength grades, glass microspheres are a preferred material for manufacturers seeking weight reduction without sacrificing mechanical performance. Major export origins include USA, China, and Germany, with pricing varying by grade and particle size distribution.

Before placing an order, verify the microsphere density and particle‑size distribution against the supplier’s test data. Ask for a Certificate of Analysis that includes density, size‑by‑weight curves and any relevant ASTM compliance. Confirm the supplier’s manufacturing process controls and whether any third‑party quality audits have been performed.
Logistics for glass microspheres from Petra typically involve FOB terms from the Port of Ahmedabad, with buyers arranging freight to their destination. Lead times are not disclosed publicly, so request an estimated production and shipment schedule, as well as payment terms such as T/T or LC. Ensure that the chosen Incoterm aligns with your risk management and insurance requirements.
Upon receipt, conduct a visual inspection for breakage and a bulk density test to confirm the declared true density. Arrange for third‑party testing of crush strength and moisture content if those parameters are critical to your application. Retain the supplier’s test reports and certificates for customs clearance and quality assurance records.
