We process Expanded Polystyrene (EPS) from its resin form (a small bead resembling sugar). The resin contains a pentane gas. With the addition of steam, the EPS resin expands up to 40% of its original size.
The EPS can be molded into a variety of shapes: large blocks that can be cut into sheeting for roofing, walls , and floor insulation, detail work on on houses and buildings, signage for business or trade shows, floatation for marinas or fish farms, geofoam for roads and lightweight voidfill in landscaping.
The resin can be molded to specific shapes based on the customer's needs, such as fish boxes, insulated concrete forms, packaging, growing containers, etc.
Mansonville Plastics EPS products are marketed under the trade name of "Korolite."
Styrofoam is an extruded board which requires HCFC's to produce.
A common misunderstanding about Expanded Polystyrene (EPS) is that it is referred to by many people as styrofoam. Styrofoam is actually a trademark for a product that is manufactured by Dow Chemical Company.
The most notable difference is that EPS does not, and never has used CFC's or HCFC's, which are harmful to the ozone layer.
Styrofoam is an extruded board, whereas Expanded Polystyrene is a molded cellular board.
