Depron foam is most commonly used to make "Foamies," radio control model planes. Originally developed in the Netherlands, this foam is also used in food packaging and home renovation and insulation. Depron foam has several advantages over other materials including both its cost effectiveness and quality.
Depron B.V. is a company in the Netherlands that originally developed Depron foam decades ago. Depron B.V. currently develops, produces and sells over 800 items for use in packaging, renovation, insulation and graphical purposes.
Two main types of Depron foam are open-cell (EPS) and closed-cell (XPS). XPS, extruded polystyrene foam is water resistant and has a variety of uses. It is used in four types of food packaging trays produced by Depron B.V., to provide freshness and help extend the shelf life of meats and produce. XPS foam is an insulated material that is used in the production of wall and floor renovation products. Depron insulation boards are marketed as easily installed, high quality and cost effective products for the home. EPS, expanded polystyrene, foam absorbs fluids and is used in certain food packaging for this reason.
Depron foam is used in food packaging, floor and wall insulation and renovation, and display and model building. Depron foam is used for four types of food packaging that accentuate freshness: Trays, Dry Trays, Top Seal Trays and (Dry) backing boards. The difference between the Trays and Dry Trays is the ability of the Dry Trays to absorb fluids, making Dry Trays useful in the meat packaging and presentation. Depron insulation boards also insulate walls and floors using XPS foam. Its waterproof and heat-resistant nature provide an energy- and cost-efficient home renovation product, and its easy installation makes it an easy sell to the do-it-yourself customer. Depron foam is widely used in North America for model building, most often for remote control aeroplanes.
Advantages of Depron foam in the food packaging industry include its stable form, light and stackable nature, ecologically sound mono material, hygienic look and it is suitable for packaging machines. In home renovation, Depron foam provides heat insulation with a moisture protective and sound damping barrier, high-compression resistance, it covers cracks and tears and equalises irregularities, is resistant to building materials like limestone, plaster and cement, and is completely odour-resistant. Depron insulation boards are easy to handle, process and cut. For model building, Depron is strong, printable, writeable and paintable, and it punches without problem. XPS closed cell Depron is popular for model planes because it is waterproof and heat-resistant in storage.
"Foamies" are the most common models built today with Depron foam. These remote control planes were formerly built from balsa wood, and then from simple fan-fold foam, but recently Depron has been praised for its consistency and quality. Clubs meet and compete around the world for the best model designs and construction. There are hall of fame websites for the best engineered model planes and models, along with links to download designs for those who are interested.
