Whether a product is a […]
Using Phenolics in Thermoset Molding Applications
Phenolic, or phenolic molding compound, is a type of thermoset molding material. Phenolic materials have history dating all the way back to the original plastic, Bakelite, that derived from Leo Baekeland in the early 1900s. Even with a long history, phenolic thermosets are still commonly molded today for different applications and end products requiring heat […]
Using Thermosets in High Temperature Applications
Thermosets are used in molding applications requiring an end-part or product assembly to remain dimensionally stable within challenging and aggressive environments. One of the main benefits of using a thermoset in a molded application is thermosets’ heat resistance and high deflection temperatures that allow the molded components to exhibit excellent dimensional stability, durability, strength, and […]
BMC Thermoset Molding
BMC, or Bulk Molding Compound, is a common type of moldable thermoset material or composite. BMCs are unsaturated polyesters or vinyl esters, and may be injection or compression molded with thermoset molding machines. The properties of BMC molded parts exhibit exceptional dielectric strength, electrical insulation, heat resistance, and chemical resistance. These beneficial material properties lend […]
Using Molded Thermosets in Electrical Applications
Why are thermosets commonly used as a molding material for electrical parts and component assemblies? Thermosets are implemented in electrical applications due to the materials’ exceptional electrical stability, high dielectric strength, and resistance to arc and track which protect internal components from electrical charge and risk of fire or product failure. Parts including circuit breakers, […]
Automotive Applications using Molded Thermosets
Why are thermoset composites like phenolic and bulk molding compound commonly used material in automotive applications? Molded thermoset parts and components have excellent material properties with regards to resistance against high temperatures, corrosion, and chemicals and automotive fluids. Processing wise, thermosets may be injection molded, or compression molded. Thermoset injection molding is a fast-cycle process […]
Phenolic Molding
Phenolics, or phenolic molding compounds, are a type of thermoset composite or plastic molding material. Phenolics have history dating back to the very first plastic, bakelite, that derived from Leo Baekeland in the early 1900s. Despite a long history, phenolics thermosets are still commonly molded today for various applications and end products. The physical properties […]
Injection Molding Thermoset Materials
As a type of plastic material, thermosets can be molded in similar molding processes as thermoplastic materials such as nylon, ABS, and polypropylene. Thermosets can be injection, compression, and transfer molded. Each molding process offers different benefits and disadvantages depending on the finished part’s geometry, assembly, and commercial aspects of the program. OEMs and molders […]
