Molecular evolution during dynamic vulcanization of polyolefin mixtures for lead‐free thermoplastic vulcanized

Polymers for Advanced Technologies, 2019
The preparation process and the final properties of new thermoplastic lead‐free medium voltage (MV) insulation compounds based on the thermoplastic vulcanized (TPV) technology are reported and discussed at molecular level. The TPV MV insulation compounds were prepared starting from a peroxide curable lead free MV insulation, which is the actual market ...

Thermoplastic elastomers by blending and dynamic vulcanization

1995
Thermoplastic elastomers (TPEs) are a class of polymeric materials that have many of the performance-related properties of conventional thermoset elastomers but are melt processable as thermoplastics. Over the years, TPEs have evolved to become high performance TPE materials. Today they are available with a wide range of end use properties.

Properties of dynamically vulcanized EPDM and LLDPE blends

Journal of Applied Polymer Science, 1996
The tensile, rheological, and thermal properties of dynamically vulcanized ethylene–propylene–diene terpolymer (EPDM) and linear low-density polyethylene (LLDPE) blends were reported along with their crystalline structure and morphology. The EPDM/LLDPE blends were prepared in a laboratory internal mixer by simultaneous blending and vulcanization ...

Effect of dynamic vulcanization on PP/EPDM composite

Proceedings of 1998 International Symposium on Electrical Insulating Materials. 1998 Asian International Conference on Dielectrics and Electrical Insulation. 30th Symposium on Electrical Insulating Materials (IEEE Cat. No.98TH8286), 2002
Many papers are involved with the mechanical and electrical properties of rubber or composites cured in traditional way but few involve the properties of dynamically vulcanized composites. The effect of dynamic vulcanization on mechanical and electrical properties of a PP/EPDM composite was studied in our laboratory.

Modeling of dynamic mechanical properties of vulcanized fluoroelastomer

Polymer Engineering & Science, 2007
AbstractThe dynamic mechanical properties of a vulcanized fluoroelastomer (FKM) were studied over a range of temperatures and shear frequencies. Dynamic mechanical analysis and differential scanning calorimetry were used for the purpose of the study. A model was developed in order to describe FKM's viscoelastic behavior at various temperatures.

Dynamic vulcanization of acrylic rubber‐blended PVC

Journal of Applied Polymer Science, 2003
AbstractPoly(vinyl chloride) was blended with an acrylic rubber at a variety of blending ratio using a twin‐screw extruder. The acrylic rubber was compounded with sulfur and sodium stearate in a two‐roll mill prior to the blending. Dynamic vulcanization was performed in a compression mould at 170°C.

Thermoplastic Rubbers via Dynamic Vulcanization

2019
Thermoplastic dynamic vulcanizates (TDV), also called elastomer alloy thermoplastic vulcanizates, belong to a novel family of thermoplastic rubbers. Again, learning from the structure formation of melt-blended impact-modified thermoplastics will help us to understand some basic rules of the microstructure development in TDVs.

Fracture behavior of dynamically vulcanized thermoplastic elastomers

Journal of Applied Polymer Science, 2000
The energetics and micromechanisms of fracture in model dynamically vulcanized thermoplastic elastomers have been studied. Their fracture toughness values have been quantified under mode 1 loading conditions using both the critical J-integral approach and an essential work-of-fracture method.

Recent Developments on Thermoplastic Elastomers by Dynamic Vulcanization

2010
A comprehensive overview is given of the recent developments of thermoplastic vulcanizates (TPVs) with special reference to the technological advancements. TPVs combine the high volume molding capability of thermoplastics with the elastomeric properties of thermoset rubber.

Does dynamic vulcanization induce phase separation?

Soft Matter, 2014
Immiscible and miscible blends of poly(vinylidene fluoride) (PVDF) and acrylic rubber (ACM) were subjected to dynamic vulcanization to investigate the effect of crosslink density on phase separation.
