Konjac Gum is a plant that is found in China, Japan and Indonesia. The plant is part of the genus Amorphophallus. Typically, it thrives in the warmer regions of Asia. Konjac Extract Glucomannan 

Imidacloprid is a systemic insecticide which acts as an insect neurotoxin and belongs to a class of chemicals called the neonicotinoids which act on the central nervous system of insects, with much lower toxicity to mammals. The chemical works by interfering with the transmission of stimuli in the insect nervous system. Specifically, it causes a blockage of the nicotinergic neuronal pathway. By blocking nicotinic acetylcholine receptors, imidacloprid prevents acetylcholine from transmitting impulses between nerves, resulting in the insect's paralysis and eventual death. It is effective on contact and via stomach action. Because imidacloprid binds much more strongly to insect neuron receptors than to mammal neuron receptors, this insecticide is more toxic to insects than to mammals.

Specification:

Usage: Mainly used as sebacic acid ester plasticizer and nylon moulding resin raw materials, but also used as high temperature resistant lubricating oil raw materials. Its main ester products are methyl ester, isopropyl ester, butyl ester, octyl ester, nonyl ester and benzyl ester, commonly used esters are dibutyl sebacate and dioctyl sebacate. Sebacic acid plasticizer can be widely used in PVC, alkyd resin, polyester resin and polyamide molding resin, because of its low toxicity and high temperature resistance, it is often used in some special purpose resin. The nylon moulding resin produced with sebacic acid has higher toughness and lower hygroscopicity, and can also be processed into many special purpose products. Or rubber softeners, surfactants, coatings and spices.
