Thermoset Molding for Corrosive Environments

As a performance-based molding material, thermosets offer strong material properties for molded parts and components such as heat resistance, chemical resistance, and excellent electrical and insulation performance. Aside from the above property benefits, molded thermosets also provide superior resistance to corrosion over metal and many thermoplastic material solutions, making thermosets a material of choice for applications exposed to moisture, water, steam, condensation, and other wet environments. Whereas a metal or thermoplastic product assembly may be susceptible to corrosion or rust in wet environments, potentially jeopardizing the integrity of a product assembly or its internal components; parts and components molded with a thermoset will remain strong and durable, and ensuring user safety during operation and use of the product throughout its life span.

Corrosive Environments

In outdoor applications, products must be meet safety and durability requirements against exposure to aggressive elements including rain, sleet, and snow. Molding products with thermosets allow products to remain dimensionally stable and eliminate the possibility of corroding in wet environments. Applications within the outdoor cookware, outdoor lighting, HVAC, telecommunications, wind turbine, and energy industries all rely on the ability for molded thermosets to keep products, strong, dimensionally accurate, and durable over the life of the product regardless of the geographic location and weather environments the product is exposed to. Indoor applications such as consume home appliances including dishwashers, washers, dryers, and ranges or ovens utilize thermoset materials for bases,

terminal blocks, handles, side walls, and other product applications to protect against water and steam during use or cleaning. For product applications exposed to constant moisture or water, thermosets generally provide a lower water absorption % compared to many engineered thermoplastics such as glass filled nylon and ABS materials.
