What is pneumatics?
Pneumatics is the way air pressure propels and moves something, releasing stored compressed air in a controlled manner.
Pneumatics gives practical use to compressed air by moving applications such as tools and machinery used in the engineering, manufacturing, research and construction sectors, among others.
What is a polymer?
From a chemical point of view, a polymer is large molecules, macromolecules, composed by the union of smaller molecules called monomers.
The word polymer comes from the Greek terms Poly and Mers, and means "many parts."
Are a plastic and a polymer the same?
Plastics are a polymer but not all polymers are plastics, and this is because what makes a macromolecule considered a polymeric compound are its characteristics. Among them are: chemical structure, size and intermolecular and intramolecular interactions, having merely linked by covalence.
What are the most common plastics?
The most common plastics are:
- EPDM: Polyethylene-propylene-diene rubber monomer. It is an elastomer endowed with special characteristics against atmospheric agents and water. It has high resistance and elasticity, being used especially for waterproofing surfaces.
- FER Tetrafl uoroethylene-Perfl uorpropylene (Teflon FEP)
- FPM, FKM: Fluorine polymer (Viton)
- HDPE: High density polyethylene
- LDPE: Low Density Polyethylene
- PA: Polyamide
- PC: Polycarbonate
- PFA: Perfluoralkoxy (Teflon PFA). It is a fluoroplastic with good chemical resistance, temperature operation capacity and resistance to aging and time, low friction resistance and good electrical insulation.
- PMP: Polymethyl pentene (TPX)
- PP: Polypropylene
- PS: Polystyrene
- PSF: Polysulfone
- PTFE Polytetra-fluoroethylene (Teflon)
- PVC Polyvinyl chloride
- PVDF Polyvinylidene fluoride
- SAN Acrylnitrile-styrene
- SI Silicone rubber
- TPU: Thermoplastic Polyurethane. It is a variety of polyurethane. Excellent flexibility, durability and abrasion resistance. It is formed by injection molding like the rest of the thermoplastics.
