WebbA brittle material experiences little deformation has poor impact resistance and low tensile strength. It does have a high compressive strength, however, and can be used for purposes such as support columns (though these are often reinforced with ductile alloys to prolong a complete fracture). WebbThermosetting plastics and thermoplastics are both polymers, but they behave differently when exposed to heat. Thermoplastics can melt under heat after curing while thermoset plastics retain their form and stay solid under heat once cured. Because thermoplastics have a low melting point, they are ideal for applications that use recycled materials.
