Composite Nylon Plastics Material PA12

Pellets PA12 Polyamide Nylon Composite
Pellets PA12 Polyamide Nylon Composite are good electrical insulators and, like other polyamides, do not affect the insulation properties due to moisture. It has good impact resistance and chemical stability. PA12 has many improved varieties in terms of plasticizing properties and reinforcing properties. And PA6 long glass

Compared to Pellets PA12 Polyamide Nylon Composite, these materials have a lower melting point and density and a very high moisture regain. PA12 long glass fiber pellets are not resistant to strong oxidizing acids. The viscosity of PA12 long glass fiber pellets depends mainly on humidity, temperature and storage time. It is very fluid. The shrinkage is between 0.5% and 2%, depending on the material variety, wall thickness and other process conditions Pellets PA12 Polyamide Nylon Composite polyamide 12 or nylon Pellets PA12 Polyamide Nylon CompositeTypical applications: water meters and other commercial equipment , cable sleeves, mechanical cams, sliding mechanisms, photovoltaic backplanes and bearings.
