“…In most of the studies, the single or twin-screw extrusion has been applied to produce PP/ EPDM blends with enhanced final properties. [34][35][36][37][38][39][40][41][42][43][44][45][46][47] This study is an effort to present an economical design/processing approach for the production of thermoplastic/thermoset polymer blends in a high-shear thermokinetic mixer. PP was chosen as the thermoplastic matrix and vulcanized EPDM was used as thermoset waste with various concentrations ranging from 20 wt% to 80 wt%.…”

“…9 –18 Incorporation of EPDM wastes into PP has been considered for the production of PP/EPDM blends with enhanced impact resistance and/or thermoplastic elastomers. 19 –37 The final material properties mainly depend on the EPDM concentration in the blends. Since EPDM wastes are commonly used in the powder form, size and shape of the particles and their distribution in polymer matrix are the critical parameters that mainly determine the properties of the final products.…”

Polypropylene (PP)-waste elastomer blends are particularly attractive as an economical way of producing sustainable materials, relieving the stress on the environment. Although PP is a commodity thermoplastic finding employment in various applications, its relatively low impact strength might be a significant factor limiting the variety of uses in many industries. Extensive consumption of thermoset elastomers has been a worldwide waste disposal problem. Here, we describe a facile, economical method for reuse of waste ethylene-propylene-diene monomer (EPDM) rubber to produce impact resistant blend materials with the PP via a high-shear thermokinetic mixer. In these blends, waste EPDM was used in various concentrations ranging from 20 to 80 wt%, as the remaining part, PP acts as a carrier matrix or a physical binder depending on the concentration in the blend. Briefly, fivefold increase was achieved in the impact resistance of PP by the addition of 60 wt% EPDM waste. The blend with 80 wt% waste EPDM shows characteristics similar to a thermoplastic elastomer. The conclusion of the study is that the blending method is quite effective to produce high-performance blend materials

“…2 Therefore, it is important to reinforce the strength of PP/ EPDM TPE by improving the interface compatibility between PP and EPDM and endow the TPE with good flame retardancy at the same time. 3 However, traditional methods to prepare PP/EPDM TPE are difficult to balance the flame retardancy and the mechanical properties.…”

A new kind of polypropylene/ethylene-propylene-diene monomer (PP/EPDM) thermoplastic elastomer (TPE) with good mechanical properties and flame retardancy was prepared via in situ peroxide-induced dynamic vulcanization using lanthanum trimethacrylate (LaTMA) as a reinforcing agent. The morphology, structure, and mechanical properties and reinforcement mechanism of PP/EPDM/LaTMA TPE were investigated by scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, rubber process analyzer, cross-link density test, and so on. The flame retardancy was investigated by limiting oxygen index (LOI) test. The results showed that when the amount of lanthanum oxide was 4.96 phr and methyl methacrylate was 7.85 phr, the compatibility between EPDM and PP was greatly improved. Besides, the tensile strength, tear strength, elongation at break, and hardness (shore A) of PP/EPDM/LaTMA TPE were increased from 6.2 MPa, 41.7 kN m À1 , 148%, and 81 up to 11.1 MPa, 77.3 kN m À1 , 365%, and 89, respectively. And the LOI of PP/EPDM/LaTMA TPE was increased to 19.0%. The SEM images, the higher G 0 , and the ionic cross-link suggested that a strong filler-filler network was formed by the polymerization and the grafted of LaTMA in the PP and EPDM phase which enhanced the compatibility between PP and EPDM. The DSC and FTIR results further proved that during the processing.
