Abstract
A drip irrigation emitter includes a cover member, a base member, and a silicone-based membrane containing ferric oxide, the membrane=e located between the two members. The membrane includes liquid silicone rubber (LSR) material and ferric oxide. The ferric oxide in volumetric percentage ranges from about 0.1% to about 0.5% of the overall volume of the LSR material.

A drip irrigation emitter comprising:
- an emitter cover member configured to be attached to an inner surface of an irrigation pipe;
- an emitter base member attached to the cover member and configured to face a lumen of the irrigation pipe and permit irrigation liquid to enter the drip irrigation emitter;
- and
- a membrane positioned between the emitter cover member and the emitter base member, wherein the membrane comprises:
- liquid silicone rubber (LSR) material and ferric oxide, wherein the ferric oxide is in volumetric percentage ranging from about 0.1% to about 0.5% of the combined overall volume of the LSR and ferric oxide materials.
