Different Applications

Insulated Panels

Insulated panels, also known as sandwich panels, are a type of building material consisting of two outer layers and a core of polyurethane insulating material. They are commonly used in construction for their thermal efficiency, structural strength, and ease of installation.

Sandwich PUF panels can be made by two distinctive processes, namely via discontinuous and continuous production lines. Discontinuous panel production refers to a manufacturing process for producing insulated panels in batches, as opposed to a continuous lamination process where panels are produced in a continuous roll fashion.

Insulated Panels

Water Tanks & Milk Chambers

Water and milk tanks can vary in size and material, i.e. plastic or steel, and are commonly used for domestic, commercial, and industrial purposes. These tanks are thermally insulated to maintain the desired temperature of the tank ingredients.

These tanks can be insulated by either manual hand pouring process or high pressure machine injection process. Depending upon the size of the tank, manual hand pouring process will be done in batches. Whereas machine injection method is usually a one shot process, which turns out to be more efficient.

Water Tanks

Pipe Section

PUF (polyurethane foam) pipe sections are pre-insulated pipes used for thermal insulation in pipelines, featuring excellent insulation properties due to their low thermal conductivity and high compressive strength.

These sections can be made direct out of mould or can be CNC cut from a block section for the desired PIR properties. Moulding processes can be undertaken both by manual hand pouring and by high pressure machine injection pouring. The chemical system for pipe section moulding needs good flow properties and a short demoulding time.

Pipe Sections

Block Section & Slabs

PUF block sections are used for insulation and construction applications, featuring high insulation properties, lightweight, and easy installation. They can be used as insulation for roofs, walls, and floors, as well as for pipe insulation, cold rooms, and refrigeration.

Block sections are made in big rectangular moulds with high pressure machine injection. The chemical system for block sections generally have a slow reaction profile, which allows for proper material injection. The system usually has a longer demoulding time due to the quantity of the chemical poured into the mould.

Block Sections

Load Bearing Supports

Load bearing supports are thermal insulation materials used to prevent heat loss in piping systems. They are made of polyurethane foam and are designed to provide structural support and prevent deformation of pipes under heavy loads.

These supports can be made directly out of moulds or be CNC cut from high density block sections. The foaming process is undertaken by high pressure machine injection. The chemical systems for high density load bearing supports usually have a moderate to slow reaction profile for proper mould filling.

Supports

PIR Blocks & Slabs

PIR block sections are high-performance thermal insulation materials used for a variety of applications, including building and construction, cold storage, and industrial processes. They are made of polyisocyanurate foam, i.e. 100% fire proof, and offer excellent thermal insulation properties with high compressive strength.

PIR block sections are highly specialized foams to manufacture and require a supervised production mechanism. The chemical systems for PIR block sections generally have a moderate to fast reaction profile. But due to high index PIR formulations, the curing time for such blocks is considerably long.

PIR Blocks

Boat Hulls & Buoyancy

Boat hulls are the watertight structures that form the outer shell of a boat or ship. Buoyancy is the upward force exerted by water on a submerged object, and it allows subjected object to float on the water.

Buoyancy foams can be made directly out of moulds or can be filled in the air gaps of boat hulls, buoys, ships, life jackets, etc. The foaming can be done either via manual hand pouring or via high pressure machine pouring. The foam has a closed cell structure and very low water absorption to support buoyancy.

Boat Hulls

Wood Imitation

PU (polyurethane) wood imitation is a synthetic material that resembles the appearance and texture of real wood. It is often used in construction and furniture manufacturing as a cost-effective and low-maintenance alternative to natural wood.

Wood imitation products can be made in both closed and open moulds. Closed mould can be made up of alluminium, steel, and FRP, and should have the capability to bear good amount of pressure with foams going upto 300 kg/cubic meters of density. Open moulds can be made up of silicone rubber and the foam density is roughly 1000 kg/cubic meters.

Wood Imitation

Thermoware Containers

Thermoware containers are food storage containers designed to keep food hot or cold for an extended period. They are typically made of PUF insulated materials such as plastic or stainless steel.

Themoware containers like tiffin boxes, ice boxes, thermos bottles, water jugs, etc. can be insulated via both manual hand pouring and low pressure machine injection processes. The chemical systems for thermoware applications have a relatively faster reaction profile with low free rise densities.

Grouting & Tunneling

Grouting & Tunelling is the process of injecting a polyurethane resin-hardner mix into grounds, walls, and roofs to fill voids, stabilize soil or rock, or to block unnecessary water seepages.

Grouting & Tunneling can only be done via high pressure machine injection process. Hydrophobic grouting refers to the system wherein polyurethane mix foams up quickly, irrespective of any water contact in the cracks, to block all the unwated water seeping in. Hydrophilic grouting refers to moisture cure systems, which block the direct source of water leakeages.

Grouting & Tunneling

Refrigeration

Refrigeration is the process of cooling and maintaining a space or substance below the ambient temperature to preserve food, beverages, or other perishable items. It involves the transfer of heat from a low-temperature environment to a high-temperature environment.

Refrigeration or applicance foams are generally made from machine injection processes. The chemical systems have a moderate to fast reaction profiles, depending upon the customer's requirements.

Refrigeration

In-Situ & Gap Filling

PUF (Polyurethane Foam) insitu gap filling is a process of filling gaps or voids in a structure or building using expanding foam made of polyurethane on site. This technique is commonly used in construction, insulation, and air sealing applications.

Both manual pouring and machine pouring can be employed in in-situ gap filling jobs, depending upon the quantum. The chemical systems for in-situ gap filling have a free rise density ranging from 30-35 kg/cubic meters, so as to give an overall density of 40 kg/cubic meters. The reaction profile is slow to moderate, depending upon the pouring process employed.

Insitu Pouring

Solar Water Heaters & Geysers

Solar water heaters are systems that use the sun's energy to heat water for household or commercial use, while geysers are electrically-powered water heaters that use a heating element to warm up the water.

Insulation foams for solar water heaters and geysers are injected via high pressure machines. These foams have a standard density of 40 kg/cubic meters and the chemical system for such foams have a fast reaction profile.

Water Heater & Geyser

Offshore FIeld Joints

Offshore field joint refers to the point where two sections of a subsea pipeline are joined together using welding techniques to create a continuous pipeline, commonly used in offshore oil and gas installations.

The polyurethane foam used in offshore field joints is a very specialized kind of foam. The foam is majorly open celled, but rigid in nature and that too of high densities. The open cell structure of the rigid foam helps the foam to stay underwater, but at the same time offers the required insulation and strengthening properties to the offshore pipeline joints.

Offshore Field Joints

Aerosol Cans

Aerosol PUF cans are containers that use a pressurized propellant to spray a polyurethane foam (PUF) insulation material onto surfaces, commonly used in construction and insulation applications.

The aerosol cans assembler or manufacturer would be given proper guidance for various component proportions and safety guidance for the assembly. These are highly specialised foams and can be used in every household for quick jobs.

Aerosol Cans

Potting Compound

Electric circuitry PUF potting is a process of encapsulating electronic components or circuits with a polyurethane foam (PUF) material to protect them from moisture, shock, and other external factors that could damage the circuitry. This method provides a cost-effective and durable solution for electronic insulation and protection in various industries, including automotive, aerospace, and telecommunications.

These foams are generally of high density and with goof fire resistant properites. The reactivity of the chemical system is moderate to slow.
