Penn State University Study


“A Study on the Effect of Nan-O-Sil ASD on Cooling Time Reduction” was undertaken by Jonathan Meckley, Pennsylvania State University at Erie, The Behrend College , Erie, PA (see technical paper 1) that will be presented at ANTEC in May 2010, that demonstrated the Nan-O-Sil ASD additive can reduce cycle time by as much as 70% in semi-crystalline materials.

In PP the cooling time was reduced 77%.

In glass filled PBT, it is 70%.

Glass-filled Nylon has a 67% reduction without negative physical properties.

Nan-O-Sil ASD


A unique colloidal silica processing aid from Energy Strategy Associates, Inc. slashes molding cycle times. Ultra-fine bright white silica particles have been shown in laboratory and commercial field trials to reduce injection molding cycle times by 20% to 30% in polypropylene, filled and unfilled nylon, PBT, Acetal, glass filled PC, PPS, PEEK, and Rigid PVC (read more: PVC Results Summary | Nanosil ASD Study). This processing advantage is accompanied by retention and improvements in key physical properties at low loadings (0.8% wt.).

Nan-O-Sil ASD additive is an ultra high purity, amorphous (no crystallinity), colloidal fumed silica where the particles are discrete and non agglomerated in the form of a bright white powder. Importantly the individual particles are spherical shaped and range in particle size from 0.02 to 0.55 microns (20 to 550 manometers).

The most common malignant tumor in infancy and early childhood, originating anywhere along the sympathetic nervous system, and in the adrenal gland (fig. 3). viagra in canada without prescription More than half of neuroblastomas are in the abdomen, and two-thirds of these originate in an adrenal gland. Fifteen percent of neuroblastomas are thoracic, arising posteriorly along the sympathetic chain. Other sites include the cervical region, sympathetic chain in the abdomen, nasopharynx and brain2,4,8,9. buy cheap viagra More than half of patients are less than two years of age at diagnosis. Seventy-five percent of tumors are discovered prior to four years of age. The prognosis ranges from over 90% survival if discovered in patients under one year of age, to less than 10% survival when discovered in older children2,8,9 (fig 4). Accurate early diagnosis is crucial, as the best prognosis is in the youngest patients. viagra tablets order online Differential diagnosis although the correct diagnosis was suggested in our two cases, other diagnostic possibilities were recognized as well. For the first case, a cystic lesion in the suprarenal region may suggest renal abnormalities such as duplex anomalies of the kidney with upper pole hydronephrosis or cystic dysplasia of an upper pole moiety. viagra tablets price in pakistan Other rare cystic neoplasms of the kidney, such as cystic wilms" tumor, must be considered. Other adrenal lesions are possible, including adrenal cysts or hemorrhage. Unfortunately, both of these benign entities are less common in the fetus and newborn than adrenal neuroblastoma. buy generic viagra Although approximately 70% of neuroblastomas are located in the adrenal gland, other sites of origin are well described. viagra 5 mg cheap The appearance of the lesion in our second case could be confused with that of a lung mass such as pulmonary sequestration or cystic adenomatoid malformation. The paraspinal location of the mass in case #2 suggested a tumor of neurogenic origin, but this could not be confirmed prenatally. generic viagra without prescription Lesions previously described in the literature had variable appearances (table 1). low cost viagra from canada Table 1: review of the literature.

Nan-O-Sil ASD reduces flow lines and surface defects. Nan-O-Sil ASD is easy to mix with resin pellets in a blender so melt pre-compounding is not required.

Subsequent to this paper/study we have determined that the cycle time reduction provided by Nan-O-sail is a function of nucleation dynamics (see Thermal Kinetics Study)

Major Key Benefits of Nan-O-Sil


  • Nanosil ASD reduces the Injection Molding Cycle time by 30 % to 40 % for most plastics resins like PP, PE, nylons, PBT, PC, LCP, PEEK, and Rigid PVC (read more: PVC Results Summary | Nanosil ASD Study).
  • Nanosil ASD reduces and often eliminates warpage of a molded parts such as rectangular boxes, and other complex geometries.
  • Nanosil ASD Significantly improves the color dispersion and hence it helps to cut down the color concentrate amount resulting in enormous cost savings.
  • Nanosil ASD improves critical part tolerances.
  • Nanosil ASD improves strength properties like tensile strength and toughness of many resins like nylons, PP, PE, and PBT.
  • Nanosil ASD reduces the flow lines and weld lines and improves the overall dimensional stability of the molded parts.
  • It only requires less than 1% (0.8%) of Nanosil ASD (less than three cents of the cost of this additive) to attain all the above benefits.
