However, these blends were not dynamically
vulcanized. Therefore it is interesting to discover the effects of ultrasonic treatment on the properties of these dynamically
vulcanized blends.
And the corrugated cardboard and release paper used to separate stacks of
vulcanized parts also are eliminated.
The
vulcanized master collet, together with a face seal inside the chuck body, completely seals the MicroCentric chuck.
Certain lines of Thermoplastic Rubber Systems (TRS), Inc.'s NexPrene 1200 Series fully
vulcanized EPDM/PP thermoplastic elastomers (TPEs) have achieved USP Class VI Certificate of Compliance for medical product applications, while others comply with FDA regulations for use in products in non-fatty, non-oily food and potable water applications, the manufacturer announces.
Key statement: The subject matter discloses a composite material comprising a first component and a second component, the first component comprising an organic element and a thermoplastic element and the second component comprising at least one element selected from the group consisting of
vulcanized rubber and tire cords.
Uniroyal was a pioneer in demonstrating that, while not possessing all the properties of
vulcanized rubber, such a TPE had sufficient properties for many applications with the added advantage of easy molding of parts and remolding of scrap.
The vulcanization of rubber under shear is called "dynamic vulcanization." Dynamically
vulcanized thermoplastic elastomer blends have been widely used in the plastics industry because of their advantages in processing; even with the presence of crosslinked elastomers, a thermoplastic nature can be obtained by the dynamic vulcanization.
They can be processed like thermoplastics but their properties are close to those of
vulcanized elastomers.
Key statement: The invention relates to a rubber composition having a good processability, and simultaneously having a rolling resistance performance and hardness after vulcanization at high levels, with which the contamination of the mold for processing due to the bleeding-out of the plasticizer can be suppressed, and in which the migration of the plasticizer and so on is suppressed to a low level; a
vulcanized rubber obtained by vulcanizing the rubber composition; and to a tire including the rubber composition as at least a part thereof.
Conventional TPVs combine a PP matrix and a
vulcanized EPDM rubber phase.
When the wet mix elastomer composite is processed with CTV Method 1, the
vulcanized wet mix elastomer composite exhibits a resistivity that A) has a natural logarithm satisfying the equation In (resistivity) [greater than or equal to] -0.1 (loading) + x, where x is 14, or B) is at least 2.9 times greater than the resistivity of a
vulcanized dry mix elastomer composite having the same composition and prepared using Comparative CTV Method 1.
