Hence, at a production level of 500 units, the total electric cost is $8,000 [$3,000 + ($10 x 500)]. The mixed cost illustrated in the above chart is called a step function. An example of such cost behavior would be the total salary expense for shift supervisors.
Product Summary. A plastic tack is a kind of tack made of the material of plastic which is a material of a wide range of synthetic or semi-synthetic organic solids used in the manufacture of industrial products. Plastics are typically polymers of high molecular mass, and may contain other substances to improve performance and/or reduce production costs.
The Polyken probe tack tester is a portable device for measuring the tackiness of pressure-sensitive adhesives and cements. The tester provides a means of bringing the tip of a probe into contact with the adhesive at controlled rates, contact times, and temperatures, and subsequently breaking the adhesive bond thus formed, also at controlled rates. The maximum force during the break is taken as the measure of tackiness.
