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.

Automotive Floor Mats

Water and milk tanks are containers used to store and collect water and milk. They 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 and less time consuming.

Gasket Seals

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.

Gasket Seals

Air Filters

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.

Cycle Saddles

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.

Sipolynate® R100HDE, Sipolynate® R100HDFRE

Cycle Saddles

Steering Wheels

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.

Recoil Pads for Guns & Riffles

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.

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 mould conditions. In closed mould conditions, the moulded density can go upto 300 kg/cubic meters. The mould needs to be of heavy duty material which should have the capability to bear good amount of pressure. In open mould conditions, the moulds can be made up of silicone and the foam densities go upto 1000 kg/cubic meters.

Footwear Insoles

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.

Automotive Gear Knobs

Grouting is the process of injecting a polyurethane resin-hardner mix into the ground, walls, and roofs to fill voids, stabilize soil or rock, or to block unnecessary water seepages. Tunneling is the method of injecting polyurethane material into the tunnel walls to stop unwated water flow.

Grouting & Tunneling can only be done via high pressure machine injection process. There are two types of grouting, namely hydrophobic and hydrophilic. 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. This type of grouting can have both fast and slow reaction profiles, depending upon the customer requirements. Hydrophilic grouting refers to the system wherein polyurethane mix does not foam up until there is any water or moisture contact in the cracks, thus ensuring to block the source of water leakeages. This is also called a moisture cure system for grouting purposes.

In-situ applications refer to techniques or methods that are carried out directly on-site, without the need for transporting samples or specimens to a laboratory. 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.
