Ordering polyurethane foam in Canada has never been easier. Factories mass producing foam sheets are now shipping them both in single and bulk orders all over the world. This factory-direct ordering method offers their foam at competitive prices for bedding, cushions, packaging and insulation. This kind of foam can be used to childproof the home and day care centers. It can also be used to hold jewelry in displays and dampen sound for acoustics. Polyurethane foam sheets are often used for furniture and mattresses, but memory foam is also available.
Polyurethane foam comes in a vast variety of textures and softness, which makes it one of the most popular types of foam available on the market. At a molecular level, it consists of a chain of polymer and urethane links, hence the term “polyurethane”.
It can be both flexible and rigid, but nevertheless, it is incredibly light. This is because polyurethane foam is low-density, which makes it perfect as a floatation device in life jackets. Rigid foam can also be used as thermal insulation and in automobile dashboards.
Semi-flexible polyurethane foam is used largely in automobile interiors. Seats, armrests and headrests all use semi-flexible polyurethane foam. This kind of foam is often placed in a mold, and then upholstered after it is manufactured.
Flexible polyurethane foam is often manufactured in blocks and then cut into a desired shape. Flexible foam is best used in furniture cushions and bedding.
Foam manufactures often offer these sheets in the raw, so customers can order them and replace their foam cushions themselves. This is a much superior method for replacing foam furniture cushions than including a series of dimensions in the order. This can leave room for error due to miscalculations, especially when the cushions are oddly shaped. Inputting three dimensions on a rectangular shaped cushion is easy, but some cushions like T and L shaped cushions require more measurements. Some manufactures offer a how-to guide for a DIY foam cushion replacement project. It mostly consists of tracing your old cushion cover onto a new sheet of foam.
Sometimes, polyester fiber or steel springs are used in place of polyurethane foam, but it does not offer the same comfort or durability. Steel springs recover well after you sit on them, but they wear out easier and become noisy. Polyester does not recover well at all after compression when compared to polyurethane foam. This is why most furniture manufacturers choose to use polyurethane foam.
