A chemical that causes a pesticide preparation to produce a thick foam, which aids in reducing drift.
a surfactant which when present in small amounts facilitates the formation of a foam, or enhances its colloidal stability by inhibiting the coalescence of bubbles
chemicals which break down to liberate gases during vulcanization, in order to form cells in the viscous uncured rubber matrix which stabilize as curing is completed to produce a rubber foam (formerly referred to as blowing agents)
A chemical used in gas wells to lighten the water column to promote gas production. Also, a chemical used while drilling wells with air or gas as the drilling fluid, to force water with the air and cuttings.
a chemical used to lighten the water column in gas wells, in oilwells producing gas, and in drilling wells in which air or gas is used as the drilling fluid so that the water can be forced out with the air or gas to prevent its impeding the production or drilling rate.
Chemical dry powders (azodicarbonamide, bicarbonate/acids, phenyltetrazoles) that generate gas or physical (compressed carbon dioxide, nitrogen, air or hydrocarbons) that are already a gas in the polymer melt process. Foam concentrates are formulated with chemical foaming agents.
A chemical substance or adjuvant which aids in forming a foam. Also, anti-foam agents reduce or prevent foaming in spray tanks or mixtures.
A foaming agent is a material that will decompose to release a gas under certain conditions (typically high temperature), which can be used to turn a liquid into a foam.
