What is the term for a material that allows no measurable movement of the pesticide through it during use?

The term that describes a material which allows no measurable movement of the pesticide through it during use is "Non-permeable material." Non-permeable materials are designed to prevent substances, such as pesticides, from passing through them, ensuring that there is a complete barrier between the pesticide and the environment. This characteristic is crucial for safety and efficacy in pesticide application, as it helps to prevent accidental exposure and contamination.

Chemical resistant materials, while important for protecting against degradation from pesticides, may still not be completely non-permeable. Impenetrable barriers, while conceptually similar, are not the standard term used in this context and could imply other properties that aren't directly linked to movement measurement. Protective equipment encompasses a broader range of protective measures and does not specifically refer to material permeability. Therefore, "Non-permeable material" is the most accurate and specific term related to the question.
