It also can be blended and compounded
with natural rubber to give lower cost rubber products with good physical properties.
For example, the EVA formulation compounded with the TAC produced the largest decreases in tear strength and Eb compared to the control.
Since the study's experimental CPE formulation was not compounded for a specific industrial application, the water swell numbers are higher than expected for industrial use.
Reactor TPO is less expensive to make than compounded TPO, partly because ethylene monomer is a less expensive feedstock than EP rubber, and partly because compounding has the cost of grinding, blending and extruding the rubber with PP.
I haven't seen anything in writing, but resin companies say they're willing to market at a 10-15% lower price |than equivalent compounded grades~." Processors also save by buying bulk unpigmented material and not having to store many smaller batches precolored black, gray and other colors.
with medium thermal black exhibit a very low degree of compression set.
Depending on the application's requirements and processor's preferences, SFR-100 resin may be compounded
with any number of polyolefin systems, yielding different flame and mechanical properties.
Not only are cost advantages involved, but a molder can have his own scrap custom-ground and treated, thus insuring him control not only of its content, but also any chemical resistance properties he may have compounded
into the original recipe.
Resin, silane, peroxide, and another additive package were compounded
, and melt was sampled by both a Rheometrics on-line melt indexer (introduced at NPE'88 in Chicago) and an Automatik IROS-100 on-line infrared spectrometer.
