Rubber Information

Ceaseless research and development
Varous rubber materials can be
produced from high technical skills

Daeyoung High-Chem has independent key technology made of various rubber material processed.

A rubber material, containing the original property, can be used by itself. But it is produced by adding a lot of chemicals mixed according to the kinds of rubber, the purpose of use, environment usage which is demanded for improving mechanical property, and the extension of durability.
Rubber material is produced by adding organic and inorganic chemicals mixed together, The mixing process is the key technology process to improve of product quality.
NBR Nitrile Butadiene Rubber
NBR contains more ACN, from 18% to 50% which generally makes it different
Generally it has an excellent mechanical property
It uses temperature ranging from -30꼦~100折 but uses until 120꼦 for short term Suitable NBR that are produced use until -60
FKM is mainly used high temperature with oil containing mineral or grease component
FKM Fluorocarbon Rubber
FKM contains more fluorine and structure, chemical resistant and low temperature property of rubber makes it different
It is well known as non-flammability, low gas permeability, ageing resistance, ozone resistance and excellent climate resistance
It uses temperature ranging from -20꼦~200꼦 but uses until 230꼦 for short term. -Suitable FKM that are produced use until -35꼦
FKM is mainly used high temperature with oil containing mineral or grease component
EPDM Ethylene Propylene Diene Rubber
EPDM contains good heat-resisting property, ageing resistance and ozone resistance
It has an excellent tensile strength, insulating property and low temperature property
It uses temperature ranging from -45꼦~150꼦 but uses until 175꼦 for short term Vulcanized EPDM that is shrunk temperature ranging from -45꼦~120꼦 but uses until 150꼦 for short term
EPDM is mainly used with brake oil containing glycol and high temperature water
HNBR Hhdrogenated Nitrile Butadine Rubber
HNBR is made of NBR which is selected from selective HYDRATING.
HNBR property contains more ACN and saturation, from 18% to 50% which generally makes it different.
It has an excellent mechanical property like NBR.
It uses temperature ranging from -30꼦~140꼦 with oil containing mineral or grease component but uses until 160꼦 for short term. Special type can be used until -40꼦
Q Silicone Rubber
Silicone rubber is well known as heat-resisting property, low gas permeability, excellent substance component and it has excellent resistance to special oxygen and ozone
It uses temperature ranging from -60꼦~200꼦 depend on materials but uses 230꼦 for short time. Special type can be used until -90꼦 and some of them are affected by small range of temperature
Silicone generally uses Drug industry and Food industry
CR Chlorprene Rubber
CR is excellent to ozone resistance, chemical resistance, weatherproof and ageing resistance
It has an excellent mechanical property, non-flammability and low temperature property
It uses temperature ranging from -40꼦~100꼦 but uses 120꼦 for short term, special type can be used until -55꼦
CR material uses sealing material and uses like refrigerator and manufacture of adhesives.
ACM Polyacrylate Rubber
ACM's power is in the middle class and low tensile strength, limited low temperature property but it has excellent resistance to ozone resistance, weatherproof, hydrothermal resistance
It uses temperature ranging from -20꼦~150꼦 but uses 175꼦 for short, special type can be used until -35꼦
ACM material usually uses parts of an automobile in need of a special resistance forlubricant containing addictive substances (containing sulfur) in high temperature.
FFKM Perfluoro Rubber
FFKM rubber has wide chemical resistance and strong heat-resisting property like PTFE
It is weak to expansibility of all media
It uses temperature ranging from -25꼦~240꼦 but special type can be used until 325꼦.
FFKM uses high temperature or aggressive circumstance and it generally uses in chemical industry
