"Our company was founded in 1966 as a R&D facility focusing on advances in plastics technologies. In 1998, our company won an award to develop a state of the art syntactic foam to provide improved buoyancy at a lighter weight. This small project eventually led to the development of four grades of Synfoam HP, our first commercial syntactic foam offering. Since that time our company has continued to focus on improving the properties of syntactic foam to both lower costs and enhance the performance for our valued customers. Our company prides itself on working closely with our customers to custom formulate solutions for their various projects.
Synfoam now offers over 50 off the shelf syntatcic foams that have found use in many industries beyond the typical subsea uses that most associate syntactic foam with. We are fully staffed with engineers, scientists, and a manufacturing team to meet the demand for Synfoam and help maintain strict quality controls over our syntactic foam. We are in the process of becoming ISO 9001 certified to further our commitment to operational excellence. Our offices and manufacturing facility are located in Livingston, NJ."

Syntactic foam is a high strength, light weight material that is created by using hollow spheres, typically made of glass, that are bound together with a thermoset polymer. The use of the word foam can be misleading as many people when they think of foam think of something that is weak and flexible. Here the word foam related to the cellular structure of the material, but SynFoam is a material that has incredibly high strength and modulus that makes it useful for many composite applications. SynFoam syntactic foam, with its unique properties of high strength and low density, is widely used in the subsea buoyancy industry. They provide weight reduction and buoyancy for various underwater applications and resist hydrostatic pressure and long term water exposure up to the depth at which the syntactic foam is rated.

SynFoam

SynFoam MW is a moderate cost, high performance syntactic foam designed for the most critical deep water applications. SynFoam MW has an excellent strength to weight ratio and a better cost/performance benefit than SynFoam DW. MW is typically chosen for use where cost rather than density is the primary factor in selection of syntactic foam for deep water applications. MW is offered in densities between 30 and 44 pounds per cubic foot and provides the performance necessary for standard 5K and 6K ROV's as well as other underwater vehicles where a high strength is required. SynFoam MW is available as 6” x 12” x 24” fully cured blocks. The blocks may be further machined into different sizes and shapes by the end user to meet the necessary specific tolerances and requirements. Our syntactic foam is easily bonded together with the use of our syntactic adhesive to form large structures. If you have a specific design for use with SynFoam MW we also provide final module fabrication services. Services include machining, assembly, and finishing with a quality marine based paint.

SynFoam® MW-30

SynFoam AD s a two component, room temperature curing, castable syntactic designed for casting lightweight complex shapes, where the need for acoustic transparency is a priority. Synfoam AD shows high levels of echo reduction both at ambient pressure and at operating depth. It has been used in the manufacture of sonar domes and sonar windows in submarines. The cast product provides an acoustically transparent housing that surrounds and protects a marine ship’s sophisticated sonar transducer array. SynFoam AD is available as 1, 2, and 5 gallon kits. Each kit contains an A and B side that must be mixed together prior to casting. Cure is achieved within 24 hours and full properties will be realized after 7 days at room temperature. Densities can be customized to the user's specifications. Please consult the appropriate instructions for limitations of depth of cure. If you have a specific mold for use with SynFoam AD we also provide final casting and fabrication services. Services include casting and finishing with a quality paint.
