558 is thermoset fiberglass chopped strand for compression molding process.
The 558 thermoset fiberglass chopped strands from Jushi brand represent a high-performance reinforcement material meticulously crafted to enhance the overall strength and durability of phenolic resin composites. Each strand is treated with a sophisticated silane-based sizing, which not only promotes excellent wettability and adhesion with the resin but also ensures consistent quality and performance across various manufacturing applications.
The 558 thermoset fiberglass chopped strands excel in their ability to maintain good dry flowability, allowing for easy handling and uniform distribution during the mixing and molding processes. This characteristic is crucial in achieving a homogeneous and defect-free final product. Additionally, their superior dispersibility ensures that the strands are evenly dispersed throughout the resin matrix, maximizing the reinforcing effect and improving the mechanical properties of the composite material.
Specifically designed for use in the compression molding process, the 558 thermoset fiberglass chopped strands are the perfect choice for manufacturers seeking to produce high-quality automotive components such as brake shoe facings, clutch facings, and friction plates. These components require exceptional wear resistance, thermal stability, and dimensional accuracy, all of which the 558 fiberglass chopped strands help to achieve. By incorporating these strands into their phenolic resin formulations, manufacturers can confidently produce components that meet the rigorous demands of the automotive industry.
The suitable process for cutting 558 glass fiber strands is mainly compression molding. This process can fully utilize the high hardness, fiber opening resistance, and good compatibility with rubber of 558 glass fiber chopped raw fibers, thereby producing high-quality composite material products.
558 fiberglass chopped strands can be easily handled and mixed into the resin matrix without forming clumps or agglomerations. This promotes a smoother and more uniform blending process.
The reinforcement provided by the 558 fiberglass chopped strands significantly improves the composite's mechanical properties, including its tensile strength, compressive strength, and flexural modulus. This means that the composite material is better able to withstand forces applied in various directions, making it more durable and reliable in demanding applications.
