Product Properties:
Appearance: N,N'-di-n-butylthiourea is a colourless or light yellow crystalline solid.
Solubility: soluble in organic solvents such as methanol, chloroform and ether, slightly soluble in water.
Method of Preparation:
The preparation of N,N'-di-n-butylthiourea is generally obtained by reacting n-butylamine with thiourea under appropriate conditions. The exact reaction conditions may vary depending on laboratory conditions, target purity requirements and other factors.
Properties: white to light yellow crystalline powder, relative density 1.06. soluble in ethanol, soluble in water. Relative density 1.06, soluble in ethanol, insoluble in ether, slightly soluble in diethyl ether, insoluble in water.

Product Usage: It is a fast vulcanisation accelerator for neoprene rubber, with the performance similar to that of ETU and DETU, it is suitable for the rubber with lower vulcanisation temperature, and the products have better physical properties. It can also promote the vulcanisation of natural rubber, styrene-butadiene rubber, butyl rubber and EPDM rubber. It is also the anti-ozone agent of natural rubber, chloroprene rubber, nitrile rubber and styrene butadiene rubber. No pollution, no discolouration. Mainly used in electric wires, industrial products and sponge products.

N,N'-Di-n-butylthiourea can be used as a processing aid for rubber and plastics to improve their strength and hardness.
It can also be used as a cross-linking agent for coatings and paints to increase their durability.
In addition, it can be used in the synthesis of organic catalysts and pharmaceutical intermediates.

Packing: 25kg plastic woven bag, paper-plastic composite bag, 25kg drum.

Storage: It should be stored in a cool, dry and well-ventilated place. Packed products should be stored in a cool, dry and well-ventilated place, avoiding direct sunlight, not overlapping between pallets, overlapping or high temperature will lead to abnormal compression of the products; validity period: 1 year.

Rubber Auxiliaries

Company information

The company's main import and export products include

(1)Rubber is a hot-soluble thermosetting elastomer, while plastics are hot-soluble cold-setting. Rubber because of the different types of vulcanizate body, its molding and curing temperature range, there is a considerable difference, and even due to climate change, indoor temperature and humidity affected. Therefore, the production conditions of rubber products need to be adjusted moderately at any time, if not, it may produce differences in product quality.

(2)Intermediates:It is a very important type of fine chemical products, the essence of a class of "semi-finished products", is the production of some products in the middle of the product, such as to produce a product, can be produced from the intermediates, cost savings, from the synthesis of pharmaceuticals, pesticides, paints, dyes and fragrances are widely used. In the pharmaceutical field, intermediates are an important link in the pharmaceutical industry chain, used in the process of drug synthesis of some chemical raw materials or chemical products, in a word, used to produce APIs.Our Intermediates products include Synthetic material intermediates,dye intermediates, Flavors and Fragrances intermediates.
