Thermoset and Thermo-plastics are two different forms of polymer, which can be differentiated based on the behavior when reacting to the purpose of heat. The fundamental difference between those two are, Thermoset is a material that hardens when heated, but cannot be remolded/reshaped or re-heated after the initial forming, while thermo-plastics can be reheated, remolded, and cooled as necessary without change any chemical changes. Except for temperature changes, physical and chemical properties of thermoplastic materials have low-melting points while the thermoset plastics products can withstand higher temperature without loss of its structural integrity.
1. Type of Thermoset Materials
Thermosetting polymers are made from various types of material that assist key roles and applications in the plastics fabrication industry. The two kinds of thermoset molding compound processes are Reaction Injection Molding (RIM) and Resin Transfer Molding (RTM).
Specific types of thermoset materials that are in use within the plastics fabrication industry include the following:
RIM Thermosetting Plastics:
RTM Thermosetting Plastics (Fiberglass-reinforced):
Other Types of Thermosets and Thermoset Resins:
Polyvinylidene fluoride (PVDF)
2. Types of Thermoplastic Materials
Types of thermoplastics commonly employed for manufacturing include polyethylene (PE), polyvinyl chloride (PVC) and polystyrene (PS), which oftenly used for packaging. Other groups of thermoplastics are acrylics, fluoropolymers, polyesters, polyimides, and nylons. All of these types can be melted down repeatedly and re-shaped into different forms. For example, a foam cup is a thermoplastic material man be re-melted and fabricated into a dish.
Some of the most common thermoplastic materials in use include:
Acetal Copolymer Polyoxymethylene
Acetal Homopolymer Polyoxymethylene
Polyvinyl chloride (PVC)
