Nano-Composite Nylon6
Characteristics and Basic properties
UNITIKA nanocomposite nylon "M1030DH" is a new-generation composite material superior in rigidity and heat resistance, which is made available by ultra dispersing specially-made layered silicate salt particles into a nylon resin to the nanometer size in the polymerization step using UNITIKA's proprietary method.
Comparison of the Morphology between Nonocomposite Nylon Resins and Conventional Reinforced-Grade Nylon Resins
UNITIKA nonocomposite nylons, reflecting the unique structure above, have the following characteristics
- 1. Low density and high-rigidity
The nanocomposite nylon resins have about twice greater rigidity than the nonreinforced nylon 6 resins, although their densities are similar. - 2. Low opacifying property, surface smoothness, and glossiness
Nanocomposite nylon resins are superior in appearance and surface smoothness, as they only contain small amount of minerals but no glass. - 3. Water-absorbing property
The water-absorbing speed and thus the dimensional change of nanocomposite nylon resins are smaller than general nylon resins, as nanocomposite nylon resins have higher crystallinity. - 4. Moldability
Nanocomposite nylon resins are excellent in flowability and mold replication and allow high-cycle molding, as the resins crystallize very rapidly.
