What is "Bycast" - Definition & Explanation

Bycast leather, also known as split-grain leather or PU leather, is a type of synthetic leather material commonly used in the textile industry. It is a versatile and cost-effective alternative to genuine leather, offering similar aesthetics and characteristics at a lower price point. Bycast leather is made by splitting a layer of genuine leather and then applying a polyurethane (PU) coating to the split surface. This process enhances the durability, appearance, and texture of the material.

The production of bycast leather begins with a natural leather hide. The hide is split into two layers: the top grain and the lower split. The top grain, which has a smooth and natural surface, is typically used for the production of genuine leather products. The lower split, which is less uniform and has a rougher texture, is used as the base material for bycast leather.

To create bycast leather, the split surface is coated with a layer of polyurethane resin. This coating provides several advantages. First, it enhances the durability and strength of the material, making it resistant to wear, tear, and abrasion. Bycast leather is known for its high tensile strength, which ensures that it maintains its shape and appearance over time. Second, the PU coating gives the material a consistent and uniform texture, mimicking the appearance of genuine leather. It can be embossed with patterns or grains to imitate various types of animal hides, such as cowhide or crocodile skin.

Bycast leather offers several benefits in comparison to genuine leather. It is more affordable, making it an attractive option for cost-conscious consumers. It is also easier to maintain, as it does not require special leather conditioners or treatments. Bycast leather is resistant to stains and can be cleaned with a damp cloth or mild soap and water. Furthermore, it is available in a wide range of colors and finishes, providing designers with greater flexibility in their creations.

In terms of its top users and manufacturers, bycast leather is widely utilized in various industries. It is commonly used in the production of furniture, including sofas, chairs, and upholstery. The durability and aesthetic appeal of bycast leather make it a popular choice for these applications. Additionally, it is utilized in the automotive industry for upholstery and interior components of vehicles. Bycast leather's resistance to fading, cracking, and peeling makes it suitable for automotive use, where it can endure frequent use and exposure to sunlight.

Several prominent manufacturers specialize in the production of bycast leather. Some of the notable companies include Arjowiggins, Nan Ya Plastics Corporation, Toray Industries, and Hornschuch. These manufacturers have extensive experience in the production of synthetic leather materials and offer a wide range of options in terms of colors, textures, and finishes.

In conclusion, bycast leather is a synthetic leather material made by applying a polyurethane coating to a split layer of genuine leather. It offers the look and feel of genuine leather at a more affordable price point, making it a popular choice in the textile industry. Bycast leather is known for its durability, easy maintenance, and versatility in various applications. Its top users and manufacturers include furniture and automotive industries, where it is valued for its aesthetic appeal and resilience.
This process is usually used on splits, or heavily buffed leather The finishing fim is created on a continuous release paper. An adhesive is applied to the film, and then it is pressed onto the leather. The finished leather is then removed from the paper, leaving a perfectly uniform surface. When stretched one will see a lighter color, that reverts back to the original when the pressure is released. Although stronger than a regular split hide, this is not top-grain. It is inexpensive,
