Plastics are categorized into 2 types: "thermoset plastics" and "thermoplastics".
When speaking of products that are called “plastic”, it generally means thermoplastics, which solidify at room temperature; however, they have the property of liquefying upon the application of heat. Furthermore, they are low in strength, and because they are affected by humid environments, they do not have precise dimensional accuracy.
In contrast to thermoplastics, thermoset plastics are resistant to heat, and have the property of not melting upon being exposed to a small flame. By applying heat and pressure to thermosets, a chemical reaction leads to the plastic curing and hardening. Once hardened, the plastic is transformed into an entirely different state than the resin before molding, and even if subsequently heated, does not soften and melt.
Lighter than metal and harder than ceramics, thermosets are a highly regarded resin material that can be used as a substitute for metals or ceramics, thanks to their superior properties of heat resistance, mechanical strength, dimensional accuracy and convenience of use, and products molded from thermosets are being used for functional parts in all industries.
The reason that our thermoset parts are being used in medical equipment, boat and ship parts, food processing equipment, and other industrial machines which could cause the loss of human life should they malfunction, is because we take pride in standing behind the reliability of our molded products.
The thermosets we handle are as follows.
