Environmentally safe and leach free pest repellent additives for cable application

Many plastic products contain hazardous chemicals that can leach into the surroundings.

Plastics exist in many different chemical compositions and are widespread in society and the environment. Global annual production of plastics has doubled over the past 15 years. The plastic polymers are not regarded as toxic, but there may be toxic residual chemicals, chemical additives, and degradation products in the plastic products that can leach out as they are not bound to the plastic polymer.

Environmental, health, and safety concerns with the basic raw materials used in manufacturing coated wire and cable are driving innovation and change in the industry. These concerns include the life cycle impacts of heavy metals such as lead, brominated flame-retardants, and resin systems, plasticizers, stabilizers, fillers, colorants, etc.

Addressing the various environmental, health, and safety issues of coated wire and cable is not a simple and straightforward process. However, the process of developing and using cleaner alternatives has already begun, spurred by European legislative changes and customer demands.

One major component that has gained a huge demand in recent times is the use of anti-rodent, anti-pest additives. These additives prevent the wire and cable application from pest attacks and thereby help the application in achieving desired longevity.

Although the cost of such compounds is said to be a barrier, the use of pesticides in cable manufacturing has come to attention and that is definitely not an option to non-toxic rodent and pest additives for polymers. 

Pesticides are not designed for polymeric applications and they are definitely not designed for use as a masterbatch as they pose problems during processing via extrusion and also on account of leachability, compatibility, and toxicity.

They have an extremely low thermal stability thus volatilize easily during the manufacturing processes.

These hazardous substances or their degradation products can be released during all phases of the plastic life cycle. This is an unwanted situation for the manufacturer, since the leaching of additives shortens the polymer lifetime, but is certainly harmful also to humans and the environment.

Approximately 8 miles of old Pacific Bell cables are allegedly leaking lead into the waters of Lake Tahoe, and the company has agreed in a lawsuit settlement to remove the old, unused cables, court records show. 

Earlier this month, the California Sportfishing Protection Alliance, a nonprofit organization dedicated to the preservation of California’s waters, received a settlement in a lawsuit it filed in January in the United States District Court against AT&T subsidiary Pacific Bell.

The cables have been in disuse since the 1980s, when Pacific Bell switched to fiber optic cables, the California Sportfishing Protection Alliance said in a press release. They were discovered by local divers working to remove garbage from Lake Tahoe. 

The nonprofit estimates that the cables contain 63 tons of lead — or 3 pounds of lead in each foot. 

“While the amount of lead the cables have leached into Lake Tahoe is unknown, attorneys for CSPA found that three feet of cable left for one day in a tub of Lake Tahoe water leached 4800 times the amount of lead allowed to enter a source of drinking water,” the California Sportfishing Protection Alliance said in the press release. 

Contamination caused by hazardous substances is a major environmental concern. As mentioned earlier, this issue is addressed by a number of EU legislative measures and policies and the rest of the world needs to take some similar actions before it’s too late.

Our products Rodrepel™Termirepel™, and CombirepelTM are one of a kind. Rodrepel™ can be described as a rodent aversive, while Termirepel™ is a termite and insect aversive, while CombirepelTM works on the combined mechanism of Rodrepel™ and Termirepel™ and acts like a rat, insect, animal, and bird aversive.

The product is available in the form of masterbatches and can be incorporated into various base polymers. But this product is even much more than that. It works on the mechanism of repellence. It does not kill the target species that are rodents and other pests but only repels them.

This product also has a very good shelf life and does not leach out in the environment, thus being totally safe for usage. Last but definitely not least this product is also stable at high temperatures.

We also have topical applications like liquid concentrate, lacquer, and sprays that can be used near and over installed near applications.

So basically, this product is low toxic, low hazardous, and completely eco-friendly. And when the world needs a greener solution for each and every aspect of life, this product comes as a breath of fresh air.

Our products are REACH (Registration, Evaluation, Authorization and Restriction of Chemicals), RoHS (Restriction of Hazardous Substances), RoHS2 and RoHS3, APVMA, NEA – Singapore compliant, and are also FIFRA (Federal Insecticide Fungicide and Rodenticide Act) exempted. Ours are the first and only products in the world that are compliant with European Union’s Biocidal Product Regulation (EU BPR).

So, whenever you think repellence; think of us! We have a solution! Always!
