Thermoplastic Elastomers by Dynamic Vulcanization

Progress in Rubber, Plastics and Recycling Technology, 2005
The present paper introduces various topics and aspects of dynamic vulcanization as applied to thermoplastic elastomers. The classification of polymer blends and thermoplastic elastomers, the development of thermoplastic vulcanizates, and the use of various types of crosslinking systems (with special emphasis on peroxides/co-agents, and phenolic resins

Vulcan

Proceedings of the November 17-19, 1970, fall joint computer conference on - AFIPS '70 (Fall), 1970
The implementation of the man-machine interface for question-answering systems, fact-retrieval systems and others in the area of information management frequently involves a concern with non-numeric programming techniques. In addition, theorem proving algorithms and more sophisticated procedures for processing natural language text require a capability

Dynamic vulcanization and thermoplastic elastomers

Macromolecular Symposia, 2001
Ageing and electrical conductivity of thermoplastic elastomers (TPE) have been studied. It is shown that incorporation of LDPE leads to more stable structure of TPE during ageing. Electrical conductivity of TPE depends on blending condition.

Dynamically Vulcanized Thermoplastic Elastomers

Rubber Chemistry and Technology, 1996
Abstract Thermoplastic elastomers (TPEs) exhibit the functional properties of conventional thermoset rubber, yet can be processed on thermoplastic fabrication equipment. The great majority of TPEs have hetero-phase morphology, whether the TPE is derived from block copolymers, rubber-plastic compositions or ionomers. Generally speaking, the hard

Dynamic Properties of Raw and Vulcanized Polymers

Rubber Chemistry and Technology, 1951
Abstract Theoretical considerations made it probable that the usefulness of measurements of vibrational properties of vulcanizates to evaluate rubberlike qualities and heat generation under flexing might be extended to raw polymers if a suitable technique of measurement could be found.

Intensification of interfacial interaction in dynamic vulcanization

Journal of Macromolecular Science, Part B, 1998
Abstract The mechanical properties of dynamic vulcanizates depend very much on the attractive forces between the thermoplastic and rubber phases. Both in situ and separately formed block and graft copolymers were successfully used to intensify these inter facial interactions in a polymer system of polypropylene and nitrile rubber to gain a ...

Vulcanization: Conventional and Dynamic

Rubber Chemistry and Technology, 1995
Abstract Conventional vulcanization, has a history of over 150 years, during which there have been increasing needs for technology to permit more and more rapid processing before the vulcanization of a rubber article in its final shape. But, at the same time, one desired increased rates of crosslinking after the part was in its final shape, e.g.

Effect of Vulcanization on the Dynamic Properties of Rubber

Rubber Chemistry and Technology, 1959
Abstract It is a known fact that the mechanical properties of rubber depend essentially upon the density (i.e., the crosslink density) of the vulcanization network. The dependence of the “equilibrium” (statistical) modulus of elasticity upon the concentration of crosslinks as well as the dependence of the tensile strength —has been studied in a

Molecular dynamics study of replica symmetry in the vulcanization transition

Physical Review E, 1999
We report on computer simulations of the vulcanization transition of randomly crosslinked polymer melts. We focus on the order parameter between different realizations of the same distribution of random crosslinks, as well as the overlap distribution of these systems.

Dynamically Vulcanized EPDM/PP (40/60) Blends

International Journal of Polymeric Materials and Polymeric Biomaterials, 2006
Dynamically vulcanized thermoplastic elastomer (TPE) blends were first described by Fisher. In the 1960s, the usage of TPE was low. However, the consumption of TPE is increasing today. Due to hard and soft polymer phases in its structure, TPE replaced a lot of materials.
