But the [T.sub.g] values of all the blends are higher compared to that of the pure NR vulcanizates
. From this observation, we can conclude that at higher proportion of reclaim rubber an incompatible blend is obtained which increases the glass transition temperature of the vulcanizate
Conveyor and transmission belts, hoses, hoisting strips, and drive cables of PP-based thermoplastic vulcanizate
(TPV) reinforced with steel wire and cord can be made more economically with new primer and adhesive tie-layer technology from Advanced Elastomer Systems (AES), Akron, Ohio, and NV Bekaert SA of Belgium.
Key statement: Provided are surface-modified elastic bodies (e.g., gasket for syringes) each obtained by a surface modification method for modifying a rubber vulcanizate
or a thermoplastic elastomer, the method being capable of providing surfaces with excellent properties such as excellent sliding properties, excellent durability against repeated sliding motion, and excellent performance in preventing adsorption and aggregation of proteins, and allowing the surfaces to maintain the sealing properties, without using expensive self-lubricating plastics.
The new compounds are the first vulcanizate
products in the Telcar OBC family of thermoplastic olefin elastomers introduced last year by Teknor Apex.
In the extruder, EPDM vulcanizate
was compressed and conveyed by the screw to the devulcanization zone.
Pasha Rubber Products LLC (firstname.lastname@example.org), Grosse Pointe, MI, announced that its patent-pending thermoplastic vulcanizate
product, made from recycled truck tire rubber, has received approval from General Motors for use in the company's air dams and other exterior automotive parts.
* Uniprene TPV (thermoplastic vulcanizate
) compounds--UN-8045F, UN-8055F, UN-8064F, UN8073F, UN-8080F--offer thermoset rubber-like performance, yet process with the ease and speed of thermoplastics.
Zeotherm, a new high-performance thermoplastic vulcanizate
, or "super-TPV," is now available in a lower-durometer version.
The objective of the present work is to study the effects of mechanically ground fluororubber vulcanizate
powder, abbreviated as FVP, on the processing and vulcanizate
properties of a fluororubber compound based on tetrafluoroethylene/propylene/vinylidene fluoride terpolymer.
As shown in figure 1, the vulcanizate
of NR with sulfur alone shows a very long cure time at 150[degrees]C.
DuPont has designed new grades of Hytrel thermoplastic polyester elastomer and ETPV (engineering thermoplastic vulcanizate
) to meet the growing demand for soft elastomers that combine oil and heat resistance with the cost and design benefits of thermoplastic processing.
A new series of thermoplastic vulcanizate
(TPV) compounds use a special curing system that reportedly improves base color and eliminates the need for predrying.
