Nylon master rheogram

The master rheogram for poly(ethylene terephthalate) (PEI) is shown in Fig. 4.21. cept for 4 data points taken from a research paper by Wu [61], the 169 data points were obtained from a single source, namely, the manufacturer [62]. All types of grades of PET (i.e., fiber, molding, tire cord, bottle) have been unified on the master rheogram [56]. in the case of nylon, the Newtonian plateau is very distinct and covers a wide range of shear rate. The deviation from the Newtonian behavior is also not too pronounced even at considerably higher shear rates. 

Viscosity versus shear rate data from two books [35,59] and two research papers [34,60] were used to form [56] the master rheogram for nylon (PA) shown in Fig. 4.20. A total of 78 data points covering a shear-rate range from 1 to 10,0(X)/s... 

The master rheograms for filled polymers have been given by Shenoy et al. [95] on a limited number of systems. These are for filled systems of LDPE, HOPE, PP, PS, Nylon, PET, and PC using data from Refs. 33, 44, 59-61, 65, 96-102. The various filled polymer systems analyzed by them are summarized in Table B5 of Appendix B.
