Rubber Chemical Manufacturer's Qualities


Processing Steps


Formic acid is added to latex to coagulate, at this stage, rubber is a form called ribbed smoked sheet. Then it is hot air dried in smokehouses called Air-dried sheet, a better grade than this is called Pale crepe rubber.


1. Compounding


It is the process of adding chemicals like sulfur and fillers to enhance mechanical properties (Eg. carbon black)

Carbon black is a colloidal form of carbon and increases tensile strength and abrasion resistance. Other fillers include China clays, PVC, styrene, etc.


2. Mixing


This step is used to ensure uniform dispersion of ingredients, and premature vulcanization must be avoided by making sure of the absence of vulcanizing agents, which is a common problem that rubber processing industries are facing recently.


3. Vulcanization


Cross-linking of elastomer molecules, so that rubber becomes stiffer and stronger but stays extensible. Several cross-linking are directly proportional to the behavior of thermosetting plastic.
Uses of Rubber chemicals
Since Raw material as such is not suitable for commercial use, in the rubber industry in the production, synthesis, and purification treatments of rubber. The main aim is to identify the right choice for appropriate usage. The category of anti-grandaunts is used to protect the components of the machinery made of rubber and hence prolong its life. The additives that are used to improve the properties of the rubber components are called accelerators.

Rubber Chemicals Include the Following:

     
• Zinc oxide     
• Styrenated phenol     
• Poly Ethylene Glycol (PEG)     
• Dibutyl phthalate     
• Toluene     
• Stearic acid, etc.
Dimethylamine is a major chemical used in synthetic rubber, which possesses superior performance and quality. The other side of its use is that it minimizes the use of ammonia in the industry.

Zinc oxide is generally a feed supplement. It is used in the manufacturing of veterinary products as well as in the process of synthesis of micronutrients. It increases the durability and strength of rubber by linking together the rubber polymers, is used in the manufacture of seven grades of rubber and is used in the making of transparent rubber products.

Zinc stearate is used because it is comparatively light in weight and can be transported quite easily and in large quantities. It is used for chemical coatings and resist moisture."
