Waste rubber is a kind of solid waste,its main source is waste rubber products,such as Scrap tire,bicycle  tire,hose, tape, industrial groceries, etc,In

addition, part of the production process come from the cutout and waste of rubber products factory produced.
(1) classification according to the source of the rubber
According to the original source of rubber, waste rubber can be divided into natural rubber type and synthetic rubber type. Among them,according to its

composition and structure,the synthetic rubber type waste rubber can be divided into styrenebutadiene rubber, butadiene rubber, neoprene, butyl rubber,

butyl rubber, silicone rubber and fluorine rubber, polyurethane rubber, etc.
(2) classification according to Original rubber products
according to Original rubber products,waste rubber can do as follows classification:
Tues:Car tires, tractor tyres, aircraft tires, trolley tyres, etc., and the main tire by use of natural rubber, butadiene rubber, butylbenzene rubber,

etc.
Inner tire:Car tires, tractor tyres, aircraft tires, trolley tyres, etc., and the main tire by use of natural rubber, butyl rubber, styrenebutadiene

rubber.
Hose and duct tape:Main use neoprene, butyl rubber, butylbenzene rubber, butadiene rubber, ethylene-propylene rubber, natural rubber, butyl rubber, etc.
Rubber shoes:Use rubber breed basically is a natural rubber, butylbenzene rubber, butadiene rubber, ethylene-propylene rubber, silicone rubber and

fluorine rubber, etc.
Industrial groceries:Use rubber breed basically is a natural rubber, neoprene, butyl rubber, ethylene-propylene rubber, silicone rubber and fluorine

rubber, etc.
In addition, waste rubber can also according to some other properties do below classification:
According to color: divided into black, white, noise;
According to the stiffness: divided into hard rubber, soft rubber;
According to the content: divided into pure rubber products, high contains gum rubber products, low contains gum rubber products;
According to the aging degree: can be divided into slight aging products, secondary aging products, severe aging products.
Used for regeneration of waste rubber, according to its content, can further hierarchies:
Tues class:
Level 1, Contains natural rubber proportion big inflatable rubber tire tread
Level 2,Contains natural rubber proportion big pneumatic tires, two levels of the following buffer layer tread glue
Level 3, Contains natural rubber proportion big inflatable rubber tyres than cord layer, the carcass glue
Level 4 ,Contains natural rubber proportion big inflatable rubber tire cord layer, less than the carcass glue
Synthetic rubber, Contains synthetic rubber proportion is large tread gum and its carcass glue
Rubber shoes class:
Level 1,Gum rubber adhesive face
Level 2,Cloth cover rubbers glue
Miscellaneous glue class:
Level 1,Soft miscellaneous glue
Level 2,Other miscellaneous glue

Reclaimed Rubber Tires after a report showed U.S. companies created more Regenerated Rubber than expected last month, the concern to facilitate the recovery of the world’s largest economy may be missing, reducing demand for commodities.

Tokyo futures gained as much as 0.8 percent after declining 0.3 percent last week, the first defeat in three weeks. The price and the yen advanced against the dollar, thereby increasing the attractiveness of yen contracts.

investor appetite for riskier assets such as U.S. payrolls private increased from 67,000 in August increased more than the median forecast of a 40,000 increase economists polled by Bloomberg. President Barack Obama this week urged Congress to expand and develop a permanent research and development tax credit to spur job growth.

“U.S. jobs data and expectations for further economic measures to support Obama for equity and commodity markets,” said Kazuhiko Saito, a Tokyo-based analyst at brokerage Fujitomi Co., phone today .

February delivery rose as much as the rubber ¥ 300.3 ¥ 2.3 a kilogram ($ 3,560 per ton) before the start of operations of ¥ 300.2 Stock Exchange Tokyo Commodity clock in 11.44

Asian stock markets extended a global gathering of data easier job in the concern that U.S. economic growth stagnated. The MSCI Asia Pacific index rose 0.9 percent to 121.10, its highest level in four weeks. The yen fell to 84.38 per dollar from 84.31 in New York.

Obama is the presentation of the proposed tax would cost about $ 100 million over the next ten years, in a speech on 08 September, the economy in Cleveland, Ohio, according to two officials speaking under condition of anonymity before the announcement .

Oil falls

The benefits in terms of rubber fell as oil for a second day, reducing the cost of competing synthetic products are of limited use in tires. The October contract lost up to 51 cents, or 0.7 percent, to $ 74.09 a barrel in electronic trading on the New York Mercantile Exchange and was at $ 74.24 at 11:52

January-delivery rubber on the Shanghai Futures Exchange rose to 26 480 yuan ($ 3,901) per tonne, its highest level since July 2008-26425 yuan before trading begins. The price of an expanded wins fourth day that the accelerated growth in sales of passenger cars increased demand prospects of China.

Retail deliveries of cars, sport utility vehicles and multipurpose vehicles has increased 59 percent last month compared with 977,300 the year before, according to the China Automotive Technology and Research Center. The growth of 15.4 percent in July because of the incentives extended by traders outperform government measures to cool the economy.

Stocks of natural rubber in 1119 was extended to 25 tonnes 820 tonnes, based on a survey of 10 stores in Shanghai, Shandong, Yunnan, Hainan and Tianjin, said the third stock exchange in September.

Today’s product designers have a variety of prototyping processes available to them. Some still rely on traditional manufacturing methods, while others use sophisticated technologies that have been improved upon over the years. The objective is to quickly determine which process or technology is best suited for your unique application.

Traditional rapid prototyping processes that use thermoplastics or polycarbonates, i.e. Stereolithography (SLA), Fused Deposition Modeling (FDM) or Selective Laser Sintering (SLS) are great for testing form, but many times these processes are no substitute for testing with real rubber compounds that will actually be used in production.

In the early stages of the design process concept models are very useful. As the design progresses, a prototype that encompasses the size, finish, color, shape, strength, durability and material characteristics of the intended final product becomes increasingly important. Therefore, using the right material and prototyping process becomes critical.

If your prototype can accurately represent the attributes of the end-product, it is by definition functional. These requirements often include material properties (e.g. flame resistance), dimensional accuracy for compatibility with mating parts and aesthetic surface finishes for appearance.

If your prototype design can be reproduced in a manner that supports the requirements of the end-product, it is by definition manufacturable. These requirements include the ability to maintain functionality, keep within the forecasted cost structure, and support the production schedule. No matter how great your design is though, it must still be manufactured for a profit. Make sure your prototyping process takes this into account.

Finally, even though your prototype design may be functional and manufacturable, it doesn’t mean anyone will want to use it. Prototypes are the only way to really verify the viability of the design. If your design can pass the challenges associated with market trials (e.g. tradeshow displays, usability testing) and regulatory testing (e.g. FDA testing of medical devices), you’re well on your way to a successful product launch.

Companies like Vicone, who specialize in high performance rubber materials, can provide product designers the fastest, easiest and most cost-effective method of obtaining low volumes of molded or extruded rubber parts. By streamlining the “CAD model-to-prototype” process you will not only reduce your lead times, but be better able to validate your design and ensure proper fit, form and function in all testing environments.

Over the past month EPDM regrind fell $120.00 USD/TON. Scrap Butyl Tubes decreased $20.00 USD/TON, Tire Derived Fuel (TDF) was $0.57 USD/MT higher and 10 mesh #4 Tire Granule was indicated unchanged .

The Tire and Rubber Recycling Composite Index advanced 0.82% in the past 30 days. The index tracks a basket of benchmark grades of scrap and reclaimed rubber on a daily basis.
