polypropylene/natural rubber thermoplastic vulcanizates
Polypropylene/natural rubber thermoplastic vulcanizates by
A 50/50 blend of natural rubber (NR) and polypropylene (PP) were dynamically vulcanized using Electron Induced Reactive Processing (EIReP) as a function of absorbed dose (150, 250, and 350 kGy) at fixed electron energy (1.5 MeV) and dose per rotation.

Thermoplastic Vulcanizates - Scientific.Net
Abstract: Thermoplastic vulcanizates based on natural rubber and polypropylene blend (NR/PP) was prepared via dynamic vulcanization by melt mixing process at 180°C and a rotor speed of 60 rpm. Three types of vulcanizing agent (i.e., Tetramethyl thiuram disulfide (TMTD), 4,4 Dithiodimorpholine (DTDM) and Dipentamethylene thiuram tetrasulfide (Tetrone A)) were used to cure the rubber phase of NR/PP blends.

MATERIALS. A TPV is a thermoplastic and rubber combination in which the rubber phase is highly vulcanized or cross-linked and finely dispersed in a continuous thermoplastic phase, in order to arrive at properties and performance values closely approaching those of a standard thermoset rubber material.

Abstract: Maleated natural rubber (MNR) was synthesized and formulated to prepare thermoplastic natural rubber (TPNRs) by blending with copolyester (COPE). It was found that tensile strength and hardness of the TPNRs increased with increasing proportions of COPE, while the elongation at break decreased.

Properties of Thermoplastic Natural Rubber (TPNR
Thermoplastic vulcanizate (TPV) based on natural rubber (NR) and polypropylene (PP) blends were successfully prepared through a dynamic vulcanization process using Brabender Plastograph EC Plus with a rotor speed of 60 rpm at 180°C. Sulfur vulcanization system was used to cure rubber phase in the TPVs. Three grades of PP (i.e., PP700J, HP553R and HP544T) were used to blend with NR at a fixed ...

What is Santoprene? | U.S. Plastic
Santoprene™ (TPV) is a thermoplastic vulcanizate. Santoprene is fully dynamically vulcanized ethylene propylene diene monomer (EPDM) rubber in a thermoplastic matrix of polypropylene (PP). It looks, feels and behaves like rubber but, due to the PP content, offers simple, flexible part design and manufacturing.
