Dynamic vulcanization as a method to improve the mechanical properties of NR-PE blends has been discussed in detail by Choudhary et al. [30]. The physical properties of unvulcanized and vulcanized NR-HDPE blends are given in Table 7 where notations A, B, and C indicate 70 30, 50 50, 30 70 NR-HDPE blends, respectively. The subscripts C and D denote blends containing DCP and high abrasion furnace (HAF) black (40 phr), respectively. 

Now, the dream has become a reality. Figure 19.5 shows 3D-TEM images of three NR vulcanizates, cured by sulfur/N-cyclohexyl-2-benzothiazolyl-sulfenamide (CBS) curing system, CB-10, CB-40, and CB-80 containing 10, 40, and 80 phr high-abrasion furnace (HAF) carbon black. In the black and white images the contrast was reversed, and the white is identified as the carbon black. Association to aggregates is observed even in CB-10 (volume fraction is 0.0498).

Hon et introduced a micromechanical model to predict the stiffness of a filled elastomer. They evaluated a range of 2D and 3D models to predict the stiffness of both medium thermal (MT) and high abrasion furnace (HAF)-filled elastomers. They used a simple Mooney stored energy function to characterize...

A short study was made as to the ability of these reactive particles to act as reinforcing fillers for elastomers. A styrenic filler with peracetate functionality was substituted for a high abrasion furnace black in a typical SBR formulation. Only 28 phr of the styrenic filler was used as compared to 40 phr of the carbon black to compensate for the density differences. As can be seen by the results of Table 9, the reactive styrenic particle acts as a reinforcing filler for SBR. 

The polychloroprene rubber preferred is the Neoprene W type. Neoprene G would perhaps give slightly superior properties, but W-type gives the best compromise between properties and processability, (ref. 3). A special low-viscosity grade, similar to W-Ml is used. The compound contains approximately 40 phr high abrasion furnace (HAF) black to reinforce it.
