Injection Molding Rubber Compounds

Injection Molding Rubber Compounds

Rubber is a kind of high elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under very small external force. It can restore the original state after removing external force. Rubber belongs to completely amorphous polymer, its glass transition temperature (T g) is low, the molecular weight is often very large, more than hundreds of thousands.

OEM high elastic injection molding rubber compounds with reversible deformation

Product Introduction


injection molding rubber compounds.jpg

Early rubber was made from latex of rubber tree, rubber grass and so on. It was made of elastic, insulating, impermeable and air material after processing. High elastic polymer compounds. It is divided into two kinds: natural rubber and synthetic rubber. Natural rubber is made from rubber tree, rubber grass and other plants after extraction of gum; synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in industry or in all aspects of life.

The word "rubber" comes from the Indian language cau-uchu, which means "weeping tree"". Natural rubber is flowing out from the Hevea latex when tapping after solidification and drying process. In 1770, British chemist J. Priestley discovered that rubber could be used to erase pencil writing, which was called "rubber", which has been in use until now. The molecular chain of rubber can be crosslinked, and the crosslinked rubber has the ability of rapid recovery, and has good physical and mechanical properties and chemical stability when it is deformed by external force. Rubber is the basic raw material of rubber industry. It is widely used in the manufacture of tires, rubber hoses, tapes, cables and other rubber products.

Product Feature And Application


injection molding rubber compounds2.jpgHevea brasiliensis offers the most commercial rubber. It hurt (such as stem bark was cut open) will secrete large amounts of SAP containing rubber emulsion.In addition, the fig tree and some of the plants can also provide rubber. Germany was trying to obtain rubber from these plants in the second world war because of the rubber supply being cut off, but later it was converted to artificial rubber.
The original rubber tree grew in South America, but after artificial transplantation, there were a large number of rubber trees in Southeast asia. In fact, Asia has become the most important source of rubber.Rubber made from silver gum can reduce sensitivity.

Natural rubber is made from latex, and a portion of the non - rubber contained in the latex is left in the solid rubber. In general, natural rubber contains 92%-95% of rubber hydrocarbon, but not of rubber hydrocarbon, accounting for 5%-8%. Because of the different processing methods, different producing areas and different gum picking seasons, the proportion of these ingredients may be different, but basically within the scope. Protein can promote the vulcanization of rubber and delay aging. On the other hand, the protein has strong water absorption, can cause rubber moisture absorption, mildew, insulation degradation, protein and increase heat generation shortcomings.

The acetone extractives are some fatty acids and steroids, some natural antioxidants and accelerators, and can help with the powdery agent in the process of mixing and dispersion of rubber softening effect.
Ash containing mainly magnesium phosphate and calcium phosphate salts, copper, manganese, iron and other metal compounds is very small, because these valence metal ion can promote the aging of rubber, so their content should be controlled. Dry glue in water does not exceed 1%, in the process can be volatile, but the moisture content is too long, will not only make the rubber easy to mildew during storage, but also the impact of rubber processing, such as mixing with the agent is easy to agglomerate; easy to blister calendering and extrusion process, the bubble or a sponge the curing process etc..
