Custom foam inserts can be made from several different types of materials, so that anyone’s needs can be met if they have valuable and sensitive equipment to protect within a case. One of these materials, for example, is Gray Polyurethane Foam. This foam is used because its traits are superior as well as predictable in the temperature range from 0° to 250°F. With its great ease of fabrication into an array of different shapes, gray polyurethane foam is particularly adaptable to be a multi-cavity cushion material that can be custom fitted into an array of hard plastic cases. This is a fine example of why custom foam inserts are the best for giving someone’s contents a secure place.
