Glass fibres and articles thereof, except woven fabrics

CPC v2.1 Code: 3712

About glass fibres and articles thereof, except woven fabrics

cpc code 3712 covers the production and manufacturing of glass fibres and various glass fibre-based products, excluding woven fabrics. Glass fibres are an essential material in a wide range of industries, from construction and transportation to electronics and renewable energy. This industry plays a crucial role in the global economy, providing critical components and solutions for numerous applications.

Production process

The production of glass fibres and articles thereof typically involves a multi-step process. First, raw materials such as silica sand, limestone, and other minerals are melted at high temperatures to form molten glass. The molten glass is then extruded through small orifices, creating continuous glass filaments. These filaments are then processed into various forms, such as chopped strands, continuous rovings, or mats, depending on the intended application. Further processing may involve bonding, coating, or other treatments to impart specific properties to the glass fibre products.

Production inputs

The main inputs required for the production of glass fibres and articles thereof include raw materials such as silica sand, limestone, and other mineral additives. Specialized machinery, such as glass melting furnaces, fibre-forming equipment, and processing lines, are also essential for this industry. Additionally, energy sources, such as electricity or natural gas, are needed to power the high-temperature manufacturing processes.

Production outputs

The primary outputs of cpc code 3712 are glass fibres and a wide range of glass fibre-based products, including reinforcement materials, insulation, and specialty composites. These outputs are often consumed by industries such as 3811 Construction materials, 3821 Machinery and equipment, and 3832 Electronic components, where glass fibres are used to enhance strength, durability, and thermal or electrical properties of various products.
