RTP Company introduces Nylon 6 nanocomposite for extruded film or sheet

RTP Company : 17 July, 2000  (New Product)
RTP Company, has developed a new product for film or sheet extrusion that incorporates organo-clay hybrids into nylon via the compounding process. This form of lightweight nanocomposite requires a mere 2-8% loading to exhibit equivalent or better properties than typical mineral-filled compounds with 20-30% loadings.
RTP Company, has developed a new product for film or sheet extrusion that incorporates organo-clay hybrids into nylon via the compounding process. This form of lightweight nanocomposite requires a mere 2-8% loading to exhibit equivalent or better properties than typical mineral-filled compounds with 20-30% loadings.

A significant benefit of these materials in film and sheet is a four-fold improvement in oxygen transmission rate over unfilled nylon 6. Extraordinary barrier properties against moisture, gasses, and fragrances make them excellent choices for packaging applications in the cosmetics, food, medical, and electronics industries. In sheet form, the material has good transparency to aid in viewing thermoformed packaging contents.

The compound displays significant improvement in heat deflection temperature by over 35 degrees C, tensile strength by over a third, and flexural modulus by almost 50%. It is an excellent alternative when glass fiber reinforcement cannot be considered due to specific gravity, mold shrinkage/warpage, or wear. At a 5% weight loading, the compound has a stiffness equivalent to a conventional 20% mineral filled nylon with minimal increase in specific gravity.

In addition, the new compounds process as easily as neat nylon. Their viscosity does not degrade over time and is lower at the shear rates due to the orientation of the organo-clay platelets.

RTP Company, headquartered in Winona, Minnesota, is a global leader in specialty compounding. The company has seven manufacturing plants on three continents, plus sales representatives throughout North America, Europe, and Asia/Pacific. RTP Company's engineers develop customized thermoplastic compounds in over 60 different engineering resin systems for applications requiring color, conductive, flame retardant, high temperature, shielding, structural, and wear resistant properties.
