Thermoset Molding for High Temperature Applications

High Temperature Applications

Thermosets are used in molding applications requiring an end-part or product assembly to remain stable within challenging environments. These environments may include exposure to high temperatures, corrosion, or chemicals. Molded thermoset parts exhibit very good dimensional stability, even in high heat and operating temperatures. Thermosets have heat resistance up to 400-500F depending on the material formulation, whereas thermoplastic molding materials such as a nylon or ABS can disfigure, melt, or carbonize and jeopardize the integrity of a product. Parts molded from a thermoset remain dimensionally stable, allowing the molded component or assembly to remain durable over the lifespan of a product. If your part or product assembly must withstand high operating temperatures and aggressive end-use elements, choosing a thermoset as your molding material may help keep your product assembly remain safe and functioning as intended.

What Materials are Thermosets?

Thermoset Plastics are a niche grade of molding material compared to common engineered thermoplastics such as PA66 (nylons), ABS, Polypropylene. While thermosets are much less known, they have actually been around much longer. The first plastic material created, bakelite, created by Leo Baekeland in 1907 was a type of thermoset composite. Despite use dating back a century ago, thermosets are much less widely used in molding applications. For applications that do not require stringent material properties, many designers and OEMs look to thermoplastics, which are commodity grades that can be remelted and remolded. Using thermosets on the other hand require an application needing a material with much stronger properties such as temperature and corrosion resistance, high electrical strength, and low deflection properties.
