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.
Tear strength 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.
(Akron, Ohio, USA), features low-end durometer (5-20 Shore A) and thus high
tear strength and viscosity.
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 filter's pleat pack is framed in high wet strength beverage board for greater
tear strength in high moisture conditions.
