How Bakelite Sheet Is Made: Step-by-Step Process

Bakelite sheet manufacturing is a meticulous process that combines precision engineering with chemical expertise. The production begins with carefully selecting and mixing phenol and formaldehyde resins. These raw materials are then combined with reinforcing materials like paper or fabric layers. The mixture undergoes a controlled heating and pressing process, where it's subjected to high temperatures and pressures in specialized molds. This causes a chemical reaction called polymerization, transforming the liquid resin into a solid, durable material. The sheets are then cooled, trimmed, and finished to meet specific dimensional and surface requirements. Quality control measures ensure each Bakelite sheet meets rigorous standards for electrical insulation, heat resistance, and mechanical strength.

How Phenolic Cotton Sheet Is Manufactured?

Phenolic cotton sheet manufacturing is a sophisticated process that combines cotton fabric with phenolic resin to create a durable, versatile material. The process begins with selecting high-quality cotton fabric, which is then impregnated with liquid phenolic resin. This resin-soaked fabric undergoes a carefully controlled drying process to achieve the optimal resin content. Next, multiple layers of the treated fabric are stacked and subjected to heat and pressure in large hydraulic presses. This curing process causes the resin to polymerize, binding the cotton layers together and forming a rigid, laminated sheet. The final product is then cooled, trimmed, and quality checked to ensure it meets the required specifications for electrical insulation, mechanical strength, and dimensional stability.
