The versatile compound with balanced properties
Epichlorohydrin Elastomers have the balanced properties of natural rubber in line with other elastomers such as acrylonitrile butadiene rubber, polychloroprene and acrylate elastomers. Such versatility is usually not available in a single material type. Its major benefit is that it can meet the qualities of a combination of such elastomers. Our Epichlorohydrin-based Epistark™ compounds in elastomers maintain their original properties and shape over various temperatures. In addition, it is rated for continuous and extreme performance in its resistance to gas permeation.
Your choice of properties in your Epistark™ Compound
We offer Epistark™ range of compounds of several different types with exceptional properties. They are typically offered individually in the categories below or even as a combination to expand the requirements of a single Epistark™ compound,
Copolymer of Epichlorohydrin
We can produce and supply Epistark™ Copolymer compounds in a wide range of hardness with good resistance to hot and cold temperatures (operating range -40*c to 150*c), Fuel, Oil and other Solvent and Chemical resistance, & High resilience making it ideally suited for product applications such as Diaphragms, Tubing and Hose in the Fuel System and other Moulded technical products.
Homopolymer of Epichlorohydrin
We can produce and supply Epistark™ Homopolymer compounds in a wide range of hardness with excellent resistance to hot and cold temperatures (operating range -23*c to 162*c), exemplary Impermeability to ozone, and fairly good resistance to making it suitable for applications such as Tubing & Hoses requiring low permeability to gases, products in the oil exploration and other industrial pumps.
Terpolymer of Epichlorohydrin
We can produce and supply Epistark™ Terpolymer compounds in a wide range of hardness with good resistance to temperatures (operating range -40*c to 150*c), resilience making it ideally suited for product applications such as diaphragms, tubing and other moulded technical products.
Epistark™ Compounds range includes materials that deliver to your requirements
- It is about two times as impermeable to air as butyl rubber.
- Products manufactured of both homopolymer, and copolymer exhibit low swell in ASTM oils, aliphatic solvents and aromatic fuels.
- It has true low-temperature flexibility, not just a low brittle point. This puts the copolymer elastomer in the oil-resistant, low-temperature class with polysulfide and fluorinated elastomers.
- Epistark™ Compounds maintain their rubber-like qualities longer in the air than most oil-resistant elastomers.
- Most of the elastomers show a softening behaviour as ambient temperatures increase. However, Epistark™ compounds retain hardness and resilience from room temperature to 177°C (350°F) which is far better than many other elastomer types.
- MOISTURE VAPOR TRANSMISSION RATE (MVTR) Due to the high polarity of Epichlorohydrin, permeability to water vapour is in sharp contrast to the retention of dry gasses.
- Epistark™ Compounds in Copolymer and Terpolymer use amorphous materials; hence we do not see crystallisation at temperatures between 0°C and the compound's freezing point (T100).
- Epistark™ Compound have substantial resistance to motor fuels at both ambient and elevated temperatures, leveraging advantage over most elastomers that have resistance to fuel, allowing greater versatility in the design of fuel-handling equipment.
- Epistark™ Compound does emit lower volume swells in general and common liquids.
