Major Types of Natural Rubber

1. Hevea Rubber (Hevea Brasiliensis)
- The primary raw material for natural rubber comes from the Hevea tree (Hevea Brasiliensis), mainly cultivated in Southeast Asia, particularly in Thailand.

2. Sumatra Rubber
- Rubber is also produced in Sumatra, Indonesia, serving as another globally significant production region.

Applications of Natural Rubber

1. Automobile Tires:
- Natural rubber is a key raw material for the manufacturing of automobile tires due to its excellent wear resistance and elasticity.

2. Shoe Soles:
- Widely used in the production of shoe soles, providing cushioning and durability during walking.

3. Industrial Products:
- Utilized in a variety of industrial products, serving as vibration control materials and sealing materials.

4. Medical Devices:
- Used in the production of medical gloves and some medical devices due to its flexibility and biocompatibility.

Applications of RSS (Rubber Smoked Sheet) and TSR (Technically Specified Rubber):

1. RSS (Rubber Smoked Sheet):
- Automobile Tire Manufacturing:
- RSS is extensively used in the production of high-end automobile tires due to its excellent physical properties and quality, making it a reliable material for tires that require high wear resistance and durability.
- High-Quality Products:
- Additionally, RSS is employed in the manufacturing of other high-quality rubber products, including industrial goods, luxury consumer goods, and some medical devices.

2. TSR (Technically Specified Rubber):
- Automobile Parts Manufacturing:
- TSR products are widely used in the manufacturing of automobile parts. In components requiring vibration control, such as engine mounts and bushings, TSR is selected for its specific properties.
- Industrial Applications:
- Used in the manufacturing of industrial products, TSR is an ideal material for products where the flexibility and elasticity of rubber are essential.
- Medical Devices:
- TSR is also used in some medical devices, playing a crucial role in the production of medical products due to its biocompatibility.

Quick release thread protector is used to protect steel pipe thread from abrasion and damage in the process of loading, unloading and transportation. It is a kind of manual device and its structure is very simple. It is composed of three parts: main body, link stopper and compressor bar. All of the three parts are made from nr/nbr, so quick release thread protector is highly resistant to oil, abrasion and corrosion. It has solid structure and long life span, and it performs well in protecting casing thread, so it is widely used. Besides, it saves time and lowers cost.

The operation of quick release thread protector is very simple. Place the quick release thread protector at the end of steel pipe thread and then push the handle firmly toward the steel pipe center and the quick release thread protector is fixed on the pipe. You can take the quick release thread protector off steel pipe by pulling the handle up.

Chemical Name: 2-Mercapto benzimidazole

Molecular Formula:C7H6N2S

Molecular Weight: 150.19

CAS NO: 583-39-1

Chemical Name: Dibenzothiazole disulfide

Molecular Formula:C14H8N2S4

Properties: A little bitter taste. Specific gravity: 1.50--1.59. Soluble in chloroform, toluene, benzene, carbon tetrachloride. Insoluble in water and ethyl alcohol.

Application: Given flat, moderately fast cures in NR and SR. Also used in a wide range of general purpose rubber. Non-staining/non-discolouring in "white" socks; use as a plasticiser and/or retarder in polychloroprene rubber. Secondary acceleration is usually required for synthetic polymers. Better scorch safety than MBT.
