Brief description of the types of waste rubber and identification methods

First, the introduction of waste rubber

Waste rubber is a kind of solid waste. Its main source is waste rubber products, namely scrap tires, human tires, hoses, tapes, industrial groceries, etc. In addition, some of them come from scraps and waste products produced in the rubber product factory.

Second, the type of waste rubber

1. Classified by source of raw rubber:

According to the source of raw rubber, waste rubber can be classified into natural rubber type and synthetic rubber type. Among them, synthetic rubber type waste rubber can be divided into styrene-butadiene rubber, butadiene rubber, neoprene rubber, butyl rubber, nitrile rubber, silicone rubber, fluorine rubber, urethane rubber, etc. according to its composition and structure.

2, according to the original rubber product use classification:

According to the original rubber product use, the waste rubber can be classified as follows.

The tires include automobile tires, tractor tires, aircraft tires, trolley tires, bicycle tires, etc., mainly using natural natural rubber, butadiene rubber, styrene-butadiene rubber, and the like. Inner tube, including automobile tires, tractor tires, aircraft tires, trolley tires, bicycle tires, etc., mainly uses natural rubber, butyl rubber, styrene-butadiene rubber. For hoses and tapes, we mainly use neoprene, nitrile rubber, styrene butadiene rubber, butadiene rubber, ethylene propylene rubber, natural rubber and butyl rubber. Rubber shoes, the main rubber varieties used are natural rubber, styrene butadiene rubber, butadiene rubber, neoprene, nitrile rubber, urethane rubber and so on. Industrial miscellaneous goods, the main types of rubber used are natural rubber, neoprene, nitrile rubber, ethylene propylene rubber, silicone rubber, fluorine rubber and so on.

3. In addition, waste rubber can also be classified according to other properties as follows:

According to the color, it is divided into black, white and mottled colors;

According to the stiffness, it is divided into hard rubber and soft rubber;

According to the content, this pure rubber product, high rubber rubber products, low rubber rubber products;

According to the degree of aging, it can be divided into mildly aged products, medium aged products, and concentrated aged products.

The waste rubber used for regeneration can be further classified according to its content, as listed in Table 1.

Scrap rubber grade classification for reclaimed rubber
