Thermosetting plastics

Thermosetting, or thermoset, plastics are synthetic materials that undergo a chemical change when they are treated, creating a three-dimensional network. After they are heated and formed, they cannot be re-melted and reformed. Bakelite is probably the most well-known thermosetting plastic. Thermosetting plastics retain their strength and shape even when heated. This makes ideal for the … Leggi tuttoThermosetting plastics


Thermoplastics are defined as polymers that can be melted and recast almost indefinitely. They are molten when heated and harden upon cooling. When frozen, however, a thermoplastic becomes glass-like and subject to fracture. These characteristics, which lend the material its name, are reversible, so the material can be reheated, reshaped, and frozen repeatedly. As a … Leggi tuttoThermoplastics

Expanded polystyrene (EPS)

Expanded polystyrene, or EPS, is one of the most widely used commodity polymers. It has been a material of choice for more than 50 years because of its versatility, performance and cost effectiveness. It is widely used in many everyday applications. EPS is a thermoplastic product with a unique combination of qualities, including: light weight, … Leggi tuttoExpanded polystyrene (EPS)


A fluoropolymer is a fluorocarbon-based polymer with multiple strong carbon–fluorine bonds. It is characterized by a high resistance to solvents, acids, and bases. Fluoropolymers are a family of high-performance plastics. The most well-known member of this family is PTFE. PTFE is inert to virtually all chemicals and is considered to be the most slippery material in existence. These properties have made … Leggi tuttoFluoropolymers

Polyamides (PA) or nylons

Polyamides (PA), or Nylons, are semi-crystalline polymers with high impact strength (macromolecule with repeating units linked by amide bonds), abrasion resistance, tensile strength, and chemical resistivity. PA was developed in the 1930’s by DuPont through the work of W.H. Carothers. PA is formed via step-growth polymerization of diamine and amino acids. Polyamides occur both naturally … Leggi tuttoPolyamides (PA) or nylons
