Key statement: A method for manufacturing a wet rubber masterbatch that will serve as raw material for vulcanized rubber having excellent tensile strength and tear strength
and that will permit wet rubber masterbatch to be molded in a short time.
without post-cure is said to be equivalent to that of a post-cured high-strength standard LSR.
The fabric properties i.e., comfort related (absorbency, air permeability), mechanical (tensile strength, tear strength
) and aesthetic (stiffness, smooth appearance) properties were checked on all treated and untreated fabrics and sustainability of antimicrobial finish to home laundry was checked by five washes interval.
Data on tensile and tear strength
were submitted to analysis of variance (ANOVA) and Tukey's test with Statigrafics Program at a significance level of p [less than or equal to] 0.05.
Officials note that the material has a high tensile strength and a high tear strength
. It reportedly can be stretched up to 400 percent of its original length.
This, in turn, can have an effect on the abrasion and tear strength
of the treated fabric.
The refastenable seams have a shear separation strength that is less than a tensile or tear strength
of the outer cover and/or side panels.
The key production issue stemmed from the fact that the product was a thin wall section membrane material which needed higher tear strength
as the de-molding process generated high levels of scrap due to tearing.
(Akron, Ohio, USA), features low-end durometer (5-20 Shore A) and thus high tear strength
The papers produced were then calendered at two line-loads using a soft-nip laboratory calender and tested with respect to air permeability, water vapor transmission rate, grease resistance, tear strength
, and tensile strength.
The Ultem 5000B has a Tg of 225[degrees]C, offers desirable tear strength
, dielectric strength of 5,300 V/mil, and a dielectric constant of 3.3 with a dissipation factor of 0.006.
The filter's pleat pack is framed in high wet strength beverage board for greater tear strength
in high moisture conditions.
