KEY BENEFITS & ADVANTAGES of HYDRIN C2000:
Hydrin C2000 has several advantages that make it very attractive for high-performance elastomer applications:

*Outstanding Fuel / Oil Resistance: 
Hydrin C2000 is resistant to a variety of hydrocarbon fuels, including gasoline, diesel, bio-diesel.

*Low-Temperature Performance: 
Hydrin C2000 has very good flexibility at low temperatures (because of EO content), enabling use in cold environments.

*High Thermal Stability: 
Hydrin C2000 can withstand prolonged exposure to elevated temperatures (Zeon cites up to 125 °C for many ECO grades).

*Gas / Permeation Barrier: 
Excellent gas impermeability — Hydrin C2000 is useful in fuel lines, diaphragms, and other barrier-requirement parts.

*Inherent Static Dissipation: 
Because of Hydrin C2000's polyether backbone, you can achieve electrostatic dissipation without adding conductive fillers (which might leach or wear off).

*Good Ozone & Weather Resistance: 
Hydrin C2000-based elastomers resist ozone aging quite well.

*CR Replacement: 
Hydrin C2000 can substitute for polychloroprene (CR) in many uses, offering similar or better physical performance + cost benefits.

*Dynamic Property Tuning: 
Hydrin C2000 can be formulated for different mechanical behaviors — from resilient (rubber bounce) to damping (vibration absorption) depending on cure system and compounding.

PERFORMANCE/BENEFITS (WHY FORMULATORS CHOOSE HYDRIN C2000) of HYDRIN C2000:
*Excellent oil/fuel/solvent resistance combined with good heat and ozone resistance.
*Outstanding gas impermeability — important for fuel system components.
*Good low-temperature flexibility (Tg ≈ −41 °C).
*Naturally anti-static (some grades), and good dynamic fatigue resistance in many formulations when properly compounded.

KEY ATTRIBUTES of HYDRIN C2000:
*Low Temperature Fuel Resistance
Hydrin C2000 offers a unique combination of fuel resistance and low-temperature flexibility.
As illustrated, compared to other elastomers of similar cost level, Hydrin C2000 has the best resistance to Fuel C while still possessing a glass transition temperature of -41°C.

*Exceptional Heat Resistance
Standard Hydrin C2000 withstands prolonged heat exposure to 125°C.
Tensile strength is maintained after 1008 hours, 125°C exposure and hardness is minimally changed.
Hydrin C2000 is suggested for applications needing prolonged heat exposure up to 160°C short term.

*Static Dissipative
Hydrin C2000 is inherently and permanently static dissipative.
Its polyether backbone provides conductivity, making Hydrin C2000 one of the most dissipative polymers available.
These electrical properties remain uniform across molded articles.
Hydrin C2000 can be compounded to achieve resistivity values as low as 3 x 10⁵ ohms without the addition of conductive additives.

*Superior Fuel Resistance vs. CSM
Hydrin C2000 is an excellent alternative for chloro-sulfonated polyethylene (CSM) and polychloroprene (CR) rubber.
Hydrin's resistance to diesel and bio-diesel fuels is superior to that of CSM.
Compared to Hydrin C2000, CSM suffers from loss of tensile strength and high level of volume change.
As shown in the second table, heat resistance is similar to CR rubber.

CHARACTERISTICS & MATERIAL BEHAVIOR of HYDRIN C2000:
Some characteristic and performance traits of Hydrin C2000:

*Hardness Range: 
Depending on formulation, you can see a broad hardness range in elastomer parts (typically 40–90 Shore A) for Hydrin C2000 rubbers (general ECO) per rubber-selection guides.

*Elongation & Tensile Strength: 
According to selection guides, elongation can be between ~200 % to ~800%, and tensile strength is quite broad depending on compounding.

*Compression Set: 
Good performance — Hydrin C2000 can maintain sealing / shape under static compression over time in many applications.

*Flex Crack Resistance & Durability: 
Good flex-crack resistance; Hydrin C2000 is suitable for dynamic applications (hoses, diaphragms) where repeated flexing or cycling happens.

*Vibration Damping: 
Useful in mounts and isolators (vibration dampers) thanks to Hydrin C2000's mechanical damping potential.

CHEMICAL RESISTANCE PROFILE of HYDRIN C2000:
*Hydrin C2000 is excellent for many oils, aliphatic hydrocarbons, and fuels.
*Good to fair resistance to some acids; poor to some esters/ketones depending on grade.
*Resistant to ozone, oxidation, and weather.

LIMITATIONS / CONSIDERATIONS of HYDRIN C2000:
*Chemical Limitations: 
While its oil and fuel resistance is excellent, Hydrin C2000 may not resist all solvents.
According to some rubber-material guides, Hydrin C2000 is less resistant to ketones, esters, strong oxidizers — so careful selection is needed if the application exposes the elastomer to unusual or aggressive solvents.

*Compression Set vs. Heat: 
At higher temperatures over long periods, compression set might increase — as with many elastomers, there is a trade-off between flexibility, heat aging, and permanent deformation.
(Depends heavily on cure system and compounding.)

*Cost / Processing: 
Depending on grade and cure system, Hydrin C2000 may cost more than standard rubbers; extruding, molding, and bonding require proper compounding knowledge.

*Residual Monomer: 
As with many Hydrin C2000-based polymers, unreacted monomer (ECH) can be a concern; quality control and appropriate post-processing (venting / extraction) may be needed.

PHYSICAL and CHEMICAL PROPERTIES of HYDRIN C2000:
CAS number: Many supplier/product databases list Epichlorohydrin rubber (polyepichlorohydrin) under CAS 308064-69-9.

Confirm exact CAS/registration with the supplier/SDS for your specific grade/batch. 
EC / EINECS number: No single EC/EINECS number is publicly listed for the trade name — polymers/brand grades often have no unique EINECS entry. 

Molecular formula / molecular weight: Not applicable to a polymer grade — HYDRIN C2000 is a copolymer (repeating units derived from epichlorohydrin (monomer formula C₃H₅ClO) and ethylene oxide).

Appearance / form: Natural (off-white) bale / pellet rubber (raw polymer).

Relative density (specific gravity): ~1.28 g•cm⁻³. 
Glass transition temperature (Tg): ≈ −41 °C (good low-temperature flexibility). 
Chlorine content: ≈ 26 wt% Cl (typical for the C2000 grade) — chlorine in the backbone contributes oil/fuel resistance and gas impermeability. 
Thermal / use temperature: Hydrin ECO grades are specified for service up to ~125 °C (dependent on compound/antioxidants). 
Permeation / barrier properties: Excellent gas and fuel permeation resistance (better than many CR grades; some Hydrin homopolymers rival butyl rubber permeation rates). 
Electrical / surface properties: Naturally static-dissipative (antistatic) in some grades; can impart antistatic properties to plastics.
