1, Natural rubber NR

Introduction: Natural rubber nr is made from rubber latex, which is isoprene polymer. It has good abrasion resistance, high elasticity, tensile strength and elongation. In the air is easy to aging, hot and sticky, in mineral oil or gasoline easy to expand and dissolve, alkali but not resistant to strong acids.

Advantages: Good elasticity, acid resistance.

Disadvantages: No weather resistance, oil resistance (vegetable oil)

Uses: is the production of tape, hose, rubber shoes raw materials, and suitable for the production of damping parts, automotive brake oil, ethanol and other hydroxide with the use of liquid products.

2, hydrogenated butyl fine rubber HNBR

Introduction: Hydrogenated Butadiene rubber HNBR is NBR gum by hydrogenation after the removal of the partial double chain, after the hydrogenation of its temperature resistance, weatherability than the general butadiene rubber to improve a lot, oil resistance and general ding-Qing rubber similar. Generally used temperature range is-25~150℃.

Advantages: Compared to ding-fine gum has a better anti-wear property, with excellent corrosion resistance, tensile, tear and compressive characteristics, and in the ozone and other atmospheric conditions with good resistance, generally applicable to washing or washing the dishes in the detergent.

Disadvantages: Not recommended for use in alcohols, esters or aromatic solutions.

Uses: Widely used in air-conditioning refrigeration industry, environmental refrigerant R134A system seals, automotive engine system seals.

3, Ethylene-Propylene rubber EPDM

Introduction: EPDM ethylene and propylene polymerization from copolymerization, so heat resistance, anti-aging, ozone resistance, stability are very excellent, but can not sulfur sulfide. In order to solve this problem, in the EP main chain to import a small number of the third component of the chain can be added to the sulfur and EPDM, the general use of temperature-50~150℃, polar solvents such as alcohol, ketones and other resistance is excellent.

Advantages: With good weather resistance and ozone resistance, with excellent water resistance and resistance to compound, can be used in alcohols and ketones, and high-temperature vapor, the gas has good permeability.

Disadvantage: Not recommended for food use or exposure to aromatic hydrogen.

Uses: Used in high-temperature steam environment seals, sanitary equipment seals or parts, braking (braking) system of rubber parts, radiator (car water tank) in the seals and so on.
