Nanospheres are micro particles with sphere shape and hollow gas filled inside. It contains thermal conductivity properties and high strength.

Microspheres are small spherical particles, with diameters in the micrometer range (typically 1 μm to 1000 μm (1 mm)).Microspheres are sometimes referred to as microparticles. Microspheres can be manufactured from various natural and synthetic materials.

We have a large stock of Marine Diesel Generating sets & its spares. All these sets are thoroughly inspected by our technical personnel as and when the vessels arrives at the ship breaking yards & only running condition units are then added to our inventory. All majorMinor spares are available of all types of sets which are therein our stock. Also Brand new spares and Recon are available which are procured from the stores of the vessels. We can also dismantle the sets & supply just the Bare alternators or any engine parts, depending on the requirement of our valuable clients.

Radars, XS-Bands, ARPAsNon-ARPs, Gyrocompass, Repeaters, Autopilots, Course Recorders, Net Recorders, EchoVideo Sounders, GPS, Navtex, Facsimile Receivers, GMDSS Equipments, Spares Antennas, Antenna Tuners, Cables Power Supplies, Battery Chargers, Sextants, Chronometers, Barometers, Anemometers, Bridge Meters, AIS, SSAS, VDR, Ship’s Whistles etc.

We maintain a large inventory of Main Auxiliary engines & spares of 2 stroke & 4 stroke engines. We have our own team of skilled technical workers for dismantling the engines. Our Main engine spares list is updated every week as we have regular shipments throughout the world. These engines & spares are first inspected & then added to our inventory. The running wear of these spare parts are in tolerance with the re-usable standards. We also have Brand new and Recon marine spares procured from the stores of the scrapped vessels. We specialise in supplying engines in one piece to our clients who wish not to dismantle these engines due to their vulnerability for damage & misplacement & can directly be used in their required applications. On the other hand we also dismantle these engines part wise & supply these parts as per the requirements of our clients. The following are the Brands of MainAuxiliary engines we deal in:

We maintain a very large stock of Marine Anchors & Anchors chains which are in reusable condition. We clean, paint & polish these anchors before shipment & all our anchors are non-frozen & without any bend flukes & shanks. We have a wide range of these anchors ranging between 1500 kgs to 17000 kgs & almost all types are available. Most of anchors are spare anchors which are procured from the deck of the vessels at the breaking yards. All anchors supplied from our yard are in ready to use condition & can be supplied to any calling port of your vessels. We have anchor chains of U2 & U3 grade stud links ranging between 28 mm up to 105 mm. These anchor chains can be supplied with certificates procured from the scrapped vessel where these chains are bought.

Hollow Spheres are only a fraction of the density of commonly used resins. It only takes a small addition by weight of Hollow Spheres to displace heavier materials. They simultaneously add volume and reduce density. If you are looking for buoyancy, no filler performs as well as Potters Hollow Spheres. Additionally, they can save material costs; on a volume basis, microspheres are a fraction of the cost of resins.

Hollow microspheres (microballoons), loaded with drug in their outer polymer shells, were prepared by a novel emulsion-solvent diffusion method. The ethanol:dichloromethane solution of drug (tranilast or ibuprofen) and an enteric acrylic polymer were poured into an agitated aqueous solution of polyvinyl alcohol that was thermally controlled at 40 degrees C. The gas phase generated in the dispersed polymer droplet by the evaporation of dichloromethane formed an internal cavity in the microsphere of the polymer with the drug. The drugs incorporated in the solidified shell of the polymer were found to be partially or completely amorphous. The flowability and packability of the resultant microballoons were much improved compared with the raw crystals of drug. The microballoons floated continuously over the surface of acidic dissolution media containing surfactant for greater than 12 h in vitro. The drug release behavior of the microballoons was characterized as an enteric property, and drug release rates were drastically reduced depending on the polymer concentration at pH 6.8.

Hollow ceramic sphere is called cenosphere. it's a dry powder with particle size 10~300 microns having grey color.

We are offering hollow bubbles. Also called 'glass bubbles', hollow glass microspheres are made of soda lime borosilicate. Unlike the cenospheres, these 'lovely bubbles' are totally manufactured based on technical requirements demanded by specific applications. In other words, it is under control all the way from particle size, true density (effective particle density), isostatic crush strength to volume of production.

Floating fly ash is called cenosphere. It is hollow sphere particles. Dry powder with particle range 10~300 microns and grey color.

We offer fillite. Fillite is a ceramic hollow micro spheres. Petra is a largest manufacture for this product in india.

We are offering ceramic microsphere. Ceramic microspheres are unique, semi-transparent fine particle size high-strength ceramic microspheres. Petra microspheres are engineered to help you reduce costs, increase solids, enhance properties, and improve processability.

It is called hollow cenosphere. Including some gases in the balls and clean by cenosphere process. The hollow beads function as pockets of encapsulated air within the explosive matrix. When the explosive is detonated, the pockets of air become hot spots that concentrate the explosive and generate high temperatures.

A cenosphere is a lightweight, inert, hollow sphere made largely of silica and alumina and filled with air or inert gas.typically produced as a byproduct of coal combustion at thermal power plants. Cenospheres are unique free flowing powders composed of hard shelled, hollow, minute spheres. A small proportion of the pulverised fuel ash (pfa) produced from the combustion of coal in power stations is formed as cenospheres. Cenospheres are made up of silica, iron and alumina. Cenospheres have a size range from 1 to 500 microns with an average compressive strength of 3000+ psi. Colors range from white to dark gray. They are also referred to as microspheres, hollow spheres, hollow ceramic microspheres, microballoons, or glass beads.

We have in advance information of the engines & other equipments of the vessels which are scheduled to beach at the breaking yards. So in this way we are able to book the equipments well in advance after consulting with our clients.
