Production and features

The hide material used in the making of bicast is usually a portion of the fibrous, lower grade of leather that remains when the higher-grade grain layer is split off. Bicast leather is produced by building up a layer of plastic (typically

) on top of an embossed release paper known as ''casting paper''. The embossing is usually giving the appearance of top grain leather, although it may be smooth depending on the desired finish. The plastic layer may optionally include: pigment, foams of various consistencies, and adhesives. Split leather is then applied and pressed onto the plastic, which may have been dried. After the resultant bicast leather has cured, the casting paper is removed, and optionally re-used. New bicast leather can have a chemical odor, but this typically dissipates about a week after the piece is exposed to air. The use of terms like "genuine leather" or "100% leather" in relation to bicast treatment is considered a misrepresentation and therefore not permitted in some countries, including the UK, Denmark, and New Zealand. Furniture manufacturers say that the main benefit of bicast leather is its surface appearance at a low price. With constant use, however, the polyurethane layer may crack and split free of its backing, and abrasion may cause large unsightly marks.
