Urea is a white dry organic compound and a crystalline substance and has minimum of 46% nitrogen calculated in dry state. 

Urea is made by reacting carbon dioxide (CO2) with anhydrous ammonia (NH3) under pressure of 3000 psi and temperatures of around 350 deg F. Water is removed during processing and the molten matter is either converted to prills or into granules.


It is generally supplied in prills or crystals/grains. Although the colour of urea is white but the crystals are larger than prills.


Commercial Urea is available in any desired packing. However it is generally packed in 50 kg bags or bulk/loose.

Other details:

Excellent stability against polishing, scratch resistance, metal mark resistance, scuff resistance


Polyethylene wax is resistant to water and chemical materials.


Polystyrene is a versatile plastic used to make a wide variety of consumer products. As a hard, solid plastic, it is often used in products that require clarity, such as food packaging and laboratory ware. When combined with various colorants, additives or other plastics, polystyrene is used to make appliances, electronics, automobile parts, toys, gardening pots and equipment and more.

Polystyrene also is made into a foam material, called expanded polystyrene (EPS) or extruded polystyrene (XPS), which is valued for its insulating and cushioning properties. Foam polystyrene can be more than 95 percent air and is widely used to make home and appliance insulation, lightweight protective packaging, surfboards, food-service and food packaging, automobile parts, roadway and road bank stabilization systems and more.

Polystyrene is made by stringing together, or polymerising, styrene, a building-block chemical used in the manufacture of many products. Styrene also occurs naturally in foods such as strawberries, cinnamon, coffee and beef.


Polyethylene (PE), light, versatile synthetic resin made from the polymerisation of ethylene.

Polyethylene is a member of the important family of polyolefin resins.

It is the most widely used plastic in the world, being made into products ranging from clear food wrap and shopping bags to detergent bottles and automobile fuel tanks.

It can also be slit or spun into synthetic fibers or modified to take on the elastic properties of a rubber.


PP, or Polypropylene: is a thermoplastic polymer used in a wide variety of applications including packaging and labeling, textiles (e.g., ropes, thermal underwear and carpets), stationery, plastic parts and reusable containers of various types, laboratory equipment, loudspeakers, automotive components, and polymer banknotes.

Polypropylene is mainly derived from the catalytic cracking of crude oil which results in propylene. This propylene is polymerised in a polymerisation plant to produce polypropylene through linking many propylene monomers into long chain polypropylene.

Melt processing of polypropylene can be achieved via extrusion and molding. 
The most common shaping technique is injection molding, which is used for parts such as cups, cutlery, vials, caps, containers, housewares, and automotive parts.

The large number of end-use applications for polypropylene are often possible because of the ability to tailor grades with specific molecular properties and additives during its manufacture. For example, antistatic additives can be added to help polypropylene surfaces resist dust and dirt. Many physical finishing techniques can also be used on polypropylene, such as machining. Surface treatments can be applied to polypropylene parts in order to promote adhesion of printing ink and paints.
