C Tech Corporation Rodrepel Non Toxic Rodent, animal and Bird repellant

Industries Served

Rodrepel®™ is designed particularly for polymer applications. Rodrepel®™ molecules are stable up to 1400°C which can withstand almost all polymer processing temperatures.

A closer at the table below will give a fair idea how the commercially available rodenticides are not suitable for polymer processing applications. Most of them either decompose at a much lower temperature or emanate toxic fumes at processing temperatures.

Rodenticide	Dosage	Temp. Stability	Toxicity: Effects on human
Brodifacoum	0.005%	Mp- 228-232°C, Decomposes before boiling	Symptoms of acute intoxication by brodifacoum vary from an increased tendency to bleed in less severe poisonings to massive haemorrhage in more severe cases. The signs of poisoning develop with a delay of one to several days after ingestion.
Copper Naphthenate		Bp- 150-250°C	Moderately toxic
Lindane		Mp- 112 °C, Bp- 323°C
Zinc phoshide	10%	Mp-1160°C	Phosphine gas can be hazardous to rodent control officers. 2.8 mg/litre of air is rapidly fatal in less than 30 minutes, but levels of 0.14-0.26 can be withstood for 30-60 minutes without consequences.
Diphacinone		Mp-145-147 C, decomposes at 338° C w/o boiling	PAN bad actor!
Cholecalciferol		Mp- 83–86 °C, Not as labile under dry conditions, but decomposed rapidly at high temperature.	Carcinogenicity, reproductive and developmental toxicity, neurotoxicity, and acute toxicity
Bromethalin		Mp- 151 C, decomposes before boiling, when heated to decomposition it emits toxic vapors of NO x, F −, and Br −	Highly Toxic, Both acute and chronic effects can occur following ingestion
Chlorophacinone	5- 25%	Mp- 140 C, Thermal decomposition products may include toxic oxides of carbon, nitrogen, and sulfur
Warfarin	0.025-0.05%	Mp- 159-161, Bp (760 torr): Decomposes.	Very toxic by inhalation, in contact with skin, and if swallowed
Bromadiolone	0.005%	Stable below 200 ºC, Mp- 200-210°C, flash-point temperature is 218°C

As (air) temperature increases, vapour hazards will increase. The vapours from many pesticides increase three to four times for each 10°C increase in temperature.

This is one reason why pesticides should be stored away from sunlight, and why it is typically recommended that pesticides not be applied when air temperatures are above 30°C.

Extrusion temperatures are as high as 100-300°C
