Hydrin T5010 is Zeon’s new product in its flagship Hydrin ECO portfolio and offers much improved processing – to the extent it can be milled on cool rolls without sticking. This new Hydrin can be sulfur or peroxide cured. This elastomer is competitively priced with neoprene and Hypalon, and still offers the resistance of an ASTM CH material.

Hydrin epichlorohydrin elastomers improve the performance of a variety of products. Their mechanical properties are very much like natural rubber and include many of the desirable properties of nitrile, polychloroprene, and polyacrylic rubbers. Additionally, the dielectric characteristics are unique and easily optimized by compounding techniques. These specialty polyether rubbers provide an overall balance of properties not available in other oil-resistant properties.

The unique properties of Hydrin have improved the performance of numerous products. Compounds of Hydrin maintain their hardness and resiliency over a broad temperature range. Permeability of gases is extremely low.

Polymer Properties

Each Hydrin elastomer grade has certain properties unmatched by other grades and other elastomers. Hydrin H is outstanding in its low gas permeability and ozone resistance. It is about three times as impermeable to air as butyl rubber. Ozone resistance is inherent in the polymer – not added by special compounding.

Vulcanizates of both Hydrin H and Hydrin C 2000 exhibit extremely low swell in ASTM oils, aliphatic solvents and aromatic fuels. Both have low hysteresis. Hydrin H has high damping at room temperature. Hydrin C 2000 has low damping, and relatively constant hardness and flexibility over a wide temperature range. It has true low-temperature flexibility, not just a low brittle point. This puts Hydrin C 2000 elastomers in the oil-resistant, low-temperature class with polysulfide and fluorinated rubbers.

Hydrin C 2000 elastomers are inherently static dissipative. They can impart unique dielectric properties to polymer blends and compounds, spanning the range from conductive through static dissipative to highly insulating, while retaining their flexibility, strength, dynamic properties and oil resistance.

Certain grades of the raw polymers are soluble and have sufficient tack to make them of interest for adhesives.

When Hydrin H, Hydrin C2000 series or Hydrin T 3000 series elastomers are blended, the properties are generally intermediate and proportional to the amount of each polymer. Properly formulated compounds have the smooth mill processing and good building tack of polychloroprene and natural rubber.

Hydrin T 3000 can be blended with conventional elastomers such as SBR or nitrile becasue of its similar cure characteristics. This allows compounding at maximum cost efficiency, using only the amount of Hydrin rubber necessary to obtain desired properties. Hydrin T 3000 rubbers can also be used to improve the properties of conventional rubber without adding excessive costs.

The low-temperature properties and fuel and oil resistance of Hydrin T3000 are the same as for Hydrin C 2000. While compression set is reduced with sulfur cures, these properties are improved when a peroxide cure is used.
