The acrylonitrile-butadiene-styrene (ABS) is an amorphous polymer produced by emulsion polymerization or by mass of acrylonitrile and styrene in the presence of polybutadiene. It 's a material mainly used in automotive components, ducts for electrical and electronic assemblies.
Polymer polyamide (PA6) semi-crystalline with good general characteristics and excellent cost / performance ratio. Due to the characteristics and cost it is a material used "for general purposes"; widely used in the mechanical gears and simple cams, pulleys, guides and mechanical parts in general. It is not used in contact with food. Because of the absorption of moisture the use in the electrical industry is limited.
Polyamide 6.6 (PA6.6) is a resin of higher quality, having higher stiffness, wear resistance and lower water absorption compared to the PA6 and a higher resistance to temperature. However, has a lower impact resistance and alower damping power. The greater rigidity than the PA6 makes it preferable in mechanical engineering when you need this feature, at the expense of shock resistance for gears, cams, pulleys, runners wear, wheelsand mechanical parts in general. It can be used, in some cases, in contact with foods.
- PA6.6 FG
FG polymer polyamide 6.6 (PA6.6 FG) is amended with glass fiberin order to increase its workability and to improve the mechanical qualities. It shows, in consequence, a wear resistance and tensile strength among the highest in absolute, it is exceptionally resistant to compression and bending. Excellent dimensional stability, also the mechanical characteristics remain high with temperatures increasing. The material is particularly suitable for the production of gears and mechanical parts to high strength, which can also work in critical environments such as construction sites, or construction equipment without being damaged. It is not used in contact with food.
The polybutylene terephthalate (PBT) is a thermoplastic polymer that is used as an insulator in the electrical and electronic. Industry the PBT is a semi-crystalline thermoplastic polymer and is part of the family of polyester. The PBT is resistant to solvents, has a slight dimensional shrinkage only in the production phase, is mechanically robust and resistant to heat up to 150 ° C (302 ° F) or 200 ° C (392 ° F) if reinforced with fiberglass.
The polycarbonate (PC) may lend itself to the formulation of compounds in different colors, compact and opaque. The aesthetics of the polycarbonate reaches its highest levels in the range of engineered polymers. Among the major applications of this material we find instead paints and sheets for the automotive, optical and computers for the medical field, packaging for electrical and electronic equipment and lighting products.
Acetal (POM) - It 'a thermoplastic material which due to its properties often competes with nylon for many of its applications. Acetals can be treated with both the conventional injection and with extrusion techniques. The material is widely used in the automotive industry and consumer electronics. The acetal polymer class (POM) was introduced in 1956 and has obtained the important application because of a good profile of properties. Two types of available acetal are homopolymer and copolymer , slightly different benefits to each. Acetals are available in fiber-reinforced and lubricated molding grades, as well as extruded shapes for machined parts.
The polyester resin (TPE) is a thermoplastic material of medium form normally used in the production of anti-extrusion rings as support to the sealing elements. Compared to other elastomers, the polyester-based materials offer the most consistent performance across the entire operating temperature range, because their properties little change from one extreme to another. Typical applications are automotive and household appliances.
Thermoplastic polyurethane (TPU) - It's a thermoplastic material used in the manufacture of flexible foam seating, of high elasticity, rigid foam insulation panels, microcellular foam seals and gaskets, wheels filled elastomer bushings for the automotive industry, compounds for electronics, high-performance adhesives, sealants and surface coatings, synthetic fibers, the lower layers of carpets and hard plastic parts.
