Think about it: a rat’s front teeth never stop growing. To keep them from getting too long, rodents have to chew on things constantly. Unfortunately, the plastic jackets around cables and wires feel like the perfect chew toy to them. Add in the fact that mice and rats love to strip away that soft plastic to build warm nests in hidden spaces, and you have a recipe for disaster.
The damage from this natural habit is massive. Rodents chewing through power, communication, and fiber optic cables cause severe structural damage to infrastructure. This hidden problem leads to huge headaches:
-
Dangerous Safety Risks: Chewed wires expose bare metal, leading to short circuits, equipment failures, and even electrical fires.
-
Massive Financial Losses: A single chewed control cable can shut down an entire factory line, and telecom companies spend fortunes repairing internet outages caused by a single rat.
-
Repair Nightmares: Because rodents hide inside walls or underground pipes, finding and fixing a chewed wire often costs way more in labor than the price of the cable itself.
While you could wrap cables in thick metal armor, that makes them heavy, stiff, and much more expensive to manufacture. At Hansk New Materials, we’ve developed a smarter defense that gets mixed right into the plastic itself: HanskMB RVA1.
HanskMB RVA1 EVA masterbatch granules, engineered for seamless integration into cable extrusion lines.
What is HanskMB RVA1?
HanskMB RVA1 is a highly specialized Rodent Repellent masterbatch. It is an Ethylene-Vinyl Acetate (EVA) copolymer compound designed to be integrated directly into the polymer matrix during the manufacturing of cable jackets.
How it Works: Sensory Deterrence
Rather than relying on toxic chemicals, RVA1 utilizes a potent capsaicin-based active matrix. When a rodent attempts to chew on a treated cable, the active compound causes extreme, non-lethal irritation to their oral and nasal cavities. This intense sensory shock forces the rodent to immediately terminate its gnawing behavior.
Key Advantages for Manufacturers
-
100% Eco-Friendly: The active compound is nature-identical and completely harmless to animal life. It is non-leaching and leaves no bioaccumulative footprint in the environment.
-
Broad Compatibility: The engineered EVA carrier resin ensures flawless integration into PE, PP, PVC, and EVA base compounds. Crucially, it does this without altering the mechanical parameters of your final product.
-
Additive Co-existence: RVA1 is fully chemically compatible with standard cable compounding additives, including flame retardants, UV blockers, and HALS (Light Stabilizers).
-
Seamless Processing: Supplied as free-flowing granules (2-5mm), the masterbatch allows for simple, direct dosing into standard commercial single or twin-screw extrusion lines. You do not need specialized feed retrofits.
Upgrade Your Product Line
By incorporating HanskMB RVA1 into your cable compounding, you immediately elevate the durability and value of your products, offering your clients true “install and forget” reliability.
