Prepregs & Resins

Solvay is a premier supplier of composite materials for the aerospace and industrial markets. Customers use our advanced material solutions for unique and demanding applications with complex geometries and varied life cycles including: primary and secondary structure, interiors, aircraft engines, tooling and other applications where a combination of lightweighting, mechanical performance and design freedom are required.

Solvay's prepregs and resin systems are the industry standard for stiffness, impact resistance and thermal performance. We offer flexible processing options to enhance design freedom and lower manufacturing costs. Our knowledgeable, experienced technical support and account teams help our customers develop complex and comprehensive aerospace composite solutions. 

Our prepregs and resin systems portfolio includes:

  • Thermoset Prepregs - The majority of our products are thermoset composites used in a variety of applications in  aerospace, automotive, oil and gas, and more. When the resin matrix and fibers are combined, an irreversible chemical bond is created when the molecules cross-link in the curing process and cause the material to be set in its final form. Thus, the material can not be remolded, reused, or recycled. However, the material’s heat resistance, stability, flexibility, and durability make it a prime candidate for cost-effective, yet high-performance design. View our entire portfolio of thermoset products.
  • Thermoplastic Prepregs - Thermoplastics provide efficiency to the aerospace market, environmental resilience to the the oil and gas market, and performance and durability to the automotive market. Because curing is not necessary, the use of thermoplastic composites tend to increase manufacturing rates. Thermoplastic parts are fabricated through rapid consolidation techniques such as compression molding, stamp forming, or pultrusion. High-impact resistance, reshaping capability, and eco-friendly manufacturing options make thermoplastics a leading solution in the composites industry.

Tooling Portfolio

Manufacturing composite parts involves creation of a mold to form the material. For part manufacturers, tooling materials require high dimensional stability and appropriate durability depending on the number of cycles. Solvay offers epoxy- and BMI-based tooling materials. Both types offer superior handling characteristics and molded surface quality, which are important in assuring accurate manufacture of composite parts.

Solvay approaches composite tooling by focusing on developing material to meet future demands. Through our focused engagement in collaborative research and development programs with government, academia and industry bodies, we are able to push the boundaries in function, cost-effectiveness, durability and robust processing. 

Solvay's tooling portfolio was developed to meet the Industrial markets' requirements:

  • Low temperature initial cures enabling our customers to use low cost master models and removes the need for intermediate tooling
  • Vacuum-only (Out of Autoclave) cure formulations being invaluable for marine, wind energy, and large tools where an autoclave would not be viable

Our tooling portfolio includes:

  • Tooling prepregs – epoxy and BMI materials
  • Tooling hardware manufacture (out of our Saint Jean, France site) – composite tools, heated tools, reusable silicone tooling
  • Ancillary products – tooling block, tooling core, backing structures and sealing systems
