Rubber banding of hydraulic and pneumatic drive system is the most widely used material. Rubber banding has excellent heat, cold, ozone resistance,and have the resistance to atmospheric aging properties. Good insulation properties. But poor tensile strength than ordinary rubber, and non-oil resistance. Suitable for home electric water heaters, electric irons, microwave ovens and other household appliances, but also for a variety of skin and indirect contact with items such as water bottles, drinking fountains and other things like this. Not recommended for use in most concentrated solvents, oils, concentrated acid and sodium hydroxide. Normal temperature range of -55 ℃ ~ 250 ℃. High temperature resistance than silicone rubber, has excellent weather resistance, ozone resistance and chemical resistance, but poor resistance to cold.
For most oils, solvents have the ability to resist, especially acid-class, aliphatic hydrocarbons and animal and vegetable oils. Rubber banding can be used to seal the demand of diesel engines, fuel systems and chemical plants. Excellent mechanical properties of the polyurethane rubber, good resistance, high pressure performance are superior to other rubber. Aging resistance, ozone resistance, oil resistance good, but when the temperature easily hydrolyzed. Suitable for high pressure resistance, wear sealed areas, such as a hydraulic cylinder.
Mainly used in aviation, instruments, electronic appliances, marine, metallurgy, machinery, automotive, medical and health departments can do all kinds of shapes of seals, gaskets, pipes, cables, also do the human body organs, blood vessels, breathable membrane and rubber molds, precision casting release agent, etc..
