Two, the introduction
1.O-ring sealing ring series
Owns a variety of materials such as Viton? rubber, butyl rubber, silicone and other materials are widely used in a variety of machinery, resistant to various types of petroleum-based oils. A variety of machinery, resistant to various types of petroleum-based oils and a variety of chemical media: the use of non-
rubber can meet the -60 ℃ - +300 ℃ temperature region, the use of pressure range: & lt; 10MPa (hydraulic), & lt; 1MPa (pneumatic) & lt; 16MPa (static sealing) of the baritone rubber and gasoline resistance
with the (90, 93, 97) expansion rate of 0.
2.Y-type seals
Embrace fluorine rubber, butyl rubber, chlorine rubber and other materials, widely used in hydraulic, mechanical, pneumatic and other industries. Resistant to petroleum-based oils with excellent abrasion resistance
Sex, the selection of different rubber can meet the -60 ℃ - +300 ℃ temperature region.
3. Silicone Rubber Series
Equipped with advanced testing equipment, clean and dust-free workshop. The products are widely used in electronics, medical equipment, food and other industries.
There are many kinds of domestic and imported silicone rubber, the use of temperature can meet the -60 ° - +300 ° C, the products can meet the oil resistance, steam resistance, medical, edible transparent, high strength
degree, flame retardant, conductive silicone rubber and so on.
4. Fluoroelastomer series products
The company's production of fluorine rubber series products, widely used in automotive, shipbuilding, military, electronic and electrical industries, working temperature -40 ℃ +300 ℃, can be resistant to fuel
oil, high temperature, Freon, resistance to hot water, steam and very good chemical corrosion resistance, welcome to customize the purchase of our customers.
5. PTFE series products
PTFE gaskets have high temperature resistance, corrosion resistance, even at high temperatures and concentrated acids, alkalis or strong oxidizing agents do not play a role, it has been widely used as
for sealing materials for pipelines, flanges, kettles, valves and containers on the sealing device. Shaped parts are produced according to the user's design drawings.
6. All kinds of shaped parts
The material used for these parts is butyl, natural, fluorine rubber, silicone, etc., which are widely used in automobile, machinery, valves and other industries, and different kinds of rubber can be used to satisfy the temperature range from -50℃ to +250℃
. The products have good wear-resisting and flexing performance, and can be made and designed according to the needs of the requirements.
