• Natural product (supply is guaranteed in a short period of time)

FOAM CORES

Foam cores are used in various markets to enhance the overall composite product. Cores are mainly used in sandwich structure and are rigid and closed cells. This means the gas is surrounded by resin and each cell is isolated from other cells, making the foam cores usable for the marine industry (preventing water immigration). Depending on usage temperature, resin compatibility, costs and manufacturing aspects, each one is more suitable for a specific application.

Foams are manufactures from a wide variety of materials, i.e. Polystyrene, Polyurethane, PVC (Polyvinyl Chloride), or PMI (Polymethacrylimide). All of the materials have different characteristics but a common point is lightweight.

 

Polystyrene
Polystyrene, also referred to as Thermocole, is made from petroleum and is one of the most widely used plastics worldwide with several billion kg used per year. Polystyrene can be either a thermoset or thermoplastic. Different degrees of Expanded Polystrene foam exist and are in comparison to other materials lighter and more buoyant. The variety of products Polystyrene can be used for make it versatile and interesting for many sectors, i.e. CD and DVD cases, surfboards or boxes. There are two types of Polystyrene: Open celled and closed celled. Open cell Polystyrene is cheaper but difficult to shape, paint or airbrush. Moreover, the open cells are not water resistant. The closed cell is more expensive but absorbs little water. Furthermore, the life expectancy is much longer in comparison to open celled Polystyrene.

Polystyrene is used in various industries. The characteristic of lightweight in combination with its low acquisition costs. One industry segment benefiting from this material is the surfboard market. Once Polystyrene is sealed with epoxy resin, the surfboards last longer and emit fewer toxic gasses.

One major advantage of Polystyrene is the cost aspect; it is fairly cheap compared to other foam materials. Furthermore, Polystyrene can be used with epoxy resin and can be shaped easily by hand or using a hot wire foam. Polystyrene is moisture resistant and easier to handle. Additionally the material is valued for its insulation qualities.

Nonetheless, the material has some disadvantages as well that impact decisions significantly. The material cannot be used with polyester resin due to the temperature and chemical sensitivity. Furthermore, Polystyrene is flammable and moreover, regarded as pollutant since it takes long to decompose. Another disadvantage to be mentioned is the poor solvent resistance and the fact that homopolymers are brittle.

In summary, polystyrene is a common foam material which is used in many businesses based on its properties:

• Cost (relatively cheap)
• Lightweight
• Moisture resistance
• Transparent Color

Polyurethane
Polyurethane is a closed cell foam that is very common in the composite industry containing a low-conductivity gas mostly hydrochlorofluorocarbons (HCFC). Due to the closed cell structure the water absorption is low making the material suitable

for the marine industry. Contrary to the Polystyrene this material can be used with polyester resin. Furthermore, it is available in ready shapes and can also be cast to a specific shape. The versatility of the materials are a major advantage and make it applicable to various projects within numerous markets.

Polyurethane are used within the composites sandwich structures but also for cushioning, packaging, buoyancy/flotation, SIPs, Insulation and Models. It can be hard like fiber, squishy like upholstery foam, protective like varnish, bouncy like rubber and sticky like glue.

The versatility of Polyurethane is a major advantage and make it suitable for a variety of fields. Furthermore, the material is flexible and durable, advantageous for specific industries. It is very cost effective and fulfills the requirements of lightweight materials needed within specific areas. Moreover, Polyurethane has a high R-value and can be either sprayed, poured or formed into rigid boards.

Polyurethane has some disadvantages that can have an impact on companies’ decisions. For instance, the R-value drops over the time and the chemical release is not environmentally friendly.

In summary, polyurethanes are versatile and can be applied to numerous projects within various sectors.

• Lightweight
• Moisture resistance
• Easy to handle
• Flexible
• Durable

PVC (Polyvinyl Chloride)
Polyvinyl Chloride are largely used in the marine industry as a result of the low water absorption. PVC is one of the most widely used and produced plastics worldwide based on two aspects: the low costs and the versatility of the material itself. The range of products made from PVC is exhaustive ranging from credit cards to toys, pipelines and many more. Moreover, the PVC’s properties can be influenced by adding plasticizers and thereby, soften or harden the material depending on the amount added.

Polyvinyl Chloride is mainly used in the composite sandwich structures based on its advantageous properties. The markets using PVC ranges from marine, aerospace, sporting goods and many more resulting from the materials’ versatility. Furthermore, two types of PVC exist that even broadens the field of application; namely: rigid and ductile. The difference is mainly obvious with regard to temperature resistance, density and physical properties.

PVC has numerous advantages approving its wide usability. First and foremost the material is cheap and cost-effective. Additionally the material has excellent durability and long-life expectancy as well as good electrical and insulation properties. Additionally, PVC has easy processing characteristics to achieve desired specifications. PVC is resistant to many solvents, including styrene and most fuels. Moreover, the material is self-extinguishing and will not rot.

Polymethacrylimide (PMI)
PMI belongs to the family of closed cell foams and is mainly used in high tech sandwich construction, for instance in combination with prepreg systems. The material is produced by mixing methacrylic acid and methacrylonitrile monomers. Due to its good mechanical properties, the foam core material can be processed in an autoclave so they can cope with high pressure without collapsing. As a result of its closed cell structure and thus its limited absorption possibilities, some processes are difficult to apply, for example, the resin infusion process.

As a consequence of the overall costs involved and its performance characteristics, PMI has been used in higher performance composite parts including helicopter rotor blades, ailerons and stringer profiles in pressure bulkheads. Generally speaking the foam core material PMI is used in the aerospace industry in a variety of structural sandwich application in either commercial, military and general aviation aircraft, satellites and helicopters.

PMI is advantageous for many reasons. The foam core material is more water absorbent than other foam cores. Furthermore, the foam core material can withstand processing temperatures up to 176°C. Additionally, PMI foams have some of the highest overall strengths and stiffness of foam cores and moreover, have a high dimensional stability. Its high fatigue life and its cured and elevated temperatures are of great advantage.

The main disadvantage of Polymethacrylimide is the cost aspect; in comparison to other foam cores PMI is very expensive.

In summary, PMI is beneficial for various markets, especially in the high performance segment based on its beneficial properties.
