What Are Polyamides? Polyamides are synthetic or natural polymers. They are made up of amide groups that are repeated and interconnected by amide links. They have increased crystallinity, and thermal and chemical resistance due to the presence of hydrogen bonds. Polyamides generally have poor resistan...
Aramids are man-made fibers with enhanced structural properties, known for their incredible tensile strength. They are used in advanced products where light weight, yet high strength is needed. Aramid fibers are made from long-chain synthetic polyamides. The chemical composition of para-aramid is ...
Synthetic materials, including polyesters, polyamides and elastanes, account for 65% of all fibers produced worldwide*. They offer great versatility of use, but to meet the trajectory of CO2emissions reduction, the use of fossil resources must be drastically reduced. Synthetics derived from renewable...
The family of microplastics includes synthetic-based particles such as polypropylene (PP), polystyrene (PS), polyamides (PA), polyethylene terephthalate (PET), polyvinyl chloride (PVC), polyacrylonitrile (PAN), polymethylacrylate (PMA), elastomers and silicone rubber with particles ranging from 1 ...
electrically nonconductive. Several of these are white and can be used with a range of colorants. for example, is called “white graphite” because it has a hexagonal, platy structure like graphite. The filler is also nonabrasive and has a low density.2Aluminum oxide and nitride are more ...
aAncamide 351A curing agent is a member of anew series of reactive polyamides developedfor use in the curing of epoxy resins in coatingsand adhesives applications. Special featuresinclude good color, color stability, excellentcorrosion resistance and superior adhesion properties. It is freely compatible...

The iron oxides magnetite and hematite are used to add density to such plastics as polypropylene, polyamides (nylons) and polyethylene, giving them the weight of metal but the versatility of plastic. These oxides have high thermal and electrical conductivity (although hematite can conduct more heat...
Several electronic devices, LCDs, gas separations, weapon industries, aerospace industry, and high-temperature polymers are using polyamides. DuPont in 1960 developed Kapton and the specification of Kapton is it remains stable or in isolation under wide ranges of temperature. That’s the reason it ...
