Thus the sandwich panels can be used where strong, stiff, lightweight panels are required. They support the properties like the rigidity, strength, compressibility, and flexibility; also maintain the shape, size, thickness, and weight. The main motive is to build or construct a panel that is light weighted. They can be formed by using thin plastic sheets as the as the core area. They should have broad bonding areas at their free ends and also to bond with outer areas. The projections can be made out of different shapes, heights, spacing, tilts etc. These different projections help to produce different characteristics in the panel being made.
As many of the characteristics can be well known at the beginning, it can be designed on the computer itself. With use of this many useful applications such as the airplane wings and the thermal boards can be designed. Thus the panels are widely used in many industrial and commercial applications of the day-to-day life. Thus, each panel possessing some different characteristics suitable for that particular environment. |

The Sandwich Panels are used mostly in huge industries and companies for their internal fixtures. These panels basically consist of two outer layers that are interconnected by another layer called the core layer. The outer layer can be sheets, slabs of wood, metal or paper. The inner material is made out of plywood, plastic sheeting or the honeycomb structure. Many of the panels of this category are also formed of inner cores made out of plastics. Placing the plastic sheet between the heated molds forms it. This results into a definite cellular structure.
The description of how this instrument works requires some pre-requisites, i.e. the person with little engineering experience can understand it well. The Sandwich Panel consists of I-beam, where its flanges are bonded to the web so as to create a structural member. The strength that is required between the two edges of the flanges is acquired by keeping the two flanges in compression and tension.
A sandwich panel is very similar to the I-beam. The things that correlate between them are the skin of the panel and the core of the panel. The skin correlates to the flanges of the I-beam where as the core relates to the I-beam Web. The panel bears a bending strength on all the directions of the plane, the X-Y plane, and Z-X plane, except the Y-Z plane. The core has the major functionality of the sandwich panel, i.e. it is responsible for holding the skins together and relative to each other. This helps in avoiding the buckle, snap, deformation or brokerage.
The core of the sandwich panel experiences mainly the shear stress. The stiffness of the material can be known by examining the shear properties. The cores that are more flexible and bend easily are known to have low shear modulus. To avoid this, another material can be bonded to the surface and creating a skin with higher tensile strength. This leads to the construction of Composite sandwich panels.

Sandwich Panel production lines
In general 3 different sandwich panel production line technologies with stone wool cores are used by sandwich panel manufacturers:
Discontinuous lines
Flexible production lines for sandwich panels which also allow for specialties with simple discontinuous press equipment. They are often used a as starter line for the production of niche panel applications - fire doors, cold stores, cabins and shelters, clean rooms, acoustic and marine panels.
Capacity up to 100,000 m² / year
Simple continuous lines
Standardised sandwich panel production lines for rigid core materials with continuous rolls or caterpillar press equipment. These lines enable manufacturers to use low investment start up equipment for the production of large insulated sandwich panels for internal and external applications.
Capacity up to 1,000,000 m² / year
Fully-automatic continuous lines
Sandwich panel production lines for rigid and extruding insulation core materials. The press and curing process operates continuously with up to 40m heated caterpillar systems. All the pre-packaging processes are controlled by a central control station.

Sandwich Panel advantages
For several decades, sandwich panels with stone wool cores have been used successfully in fast track construction, conferring numerous advantages compared to ‘build on site’ systems:
Fast installation and ease of handling
Crane assembly therefore no scaffolding required
No thermal bridges and good thermal insulation properties
Design flexibility with choice of colour finishes
Panels can be installed horizontally or vertically
Reliable robust mechanical performance
Outstanding non combustible and acoustic performance

Sandwich Panel definition
Sandwich panels for building applications are large prefabricated building products.
Sandwich panels generally consist of two outer metal sheets (steel, aluminium, other) with a stabilizing core of insulation sandwiched between them. The metal sheets are bonded to the insulation core with specialised adhesives. The outer surface of the sheets can be flat, slightly corrugated or with a significant profile (eg. for roofs or external façade design). A huge assortment of shapes, coatings and colours is available. Because sandwich panel installation requires only a limited number of mechanical fasteners (eg. screws), the resulting constructions avoid significant thermal bridging. To achieve distinctive architectural features, panels with hidden joints are available

Dedicated research and development in the PU adhesive field has been conducted to address the needs of sandwich panel manufacturers, allowing them to extend and improve their product offering with high performance PU adhesives.
To address sustainability issues regarding renewability and VOC concerns from amine catalysts two technologies has been developed:
Highly hydrophobic system including renewable material
System with innovative reactive profile allowing for faster cure time and higher green strength development

Sandwich Panel Polyurethane Adhesives
Today, because of high level of activity in the global construction industry, there are tremendous needs for high performance and differentiated Sandwich Panels
Because of the wide range of extremely diversified applications; such as cold food storage, sound insulation, or fire resistance, materials used in structural panels have to fulfill expectations and needs, and an integral part of creating a high-performance panel are polyurethane adhesives used to bond inner core foams to outer skin(s) forming composite panels.
Both Sandwich panel manufacturers and end-users will benefit from PU adhesive industry focus

Insulated Concrete Sandwich Panel Wall Ties
HK Composites produces several types of HK™ ties. All ties are designed for use in insulated concrete sandwich wall panels (CIC walls), but each is best suited for a particular application. The ties are manufactured from different high-performance, heat and alkaline resistant, engineered polymers. HK™ ties minimize the energy draining effects of thermal bridging experienced when metal ties or solid concrete sections are used to connect the concrete wythes of sandwich panels through the insulation layer. The use of HK™ low-conductivity ties results in a sandwich panel with maximum thermal performance.
