EVAL™ EVOH for Pipe Barriers

For the oil and gas pipeline industry, the incorporation of a thin layer of EVOH in a multilayer polyolefin pipe can significantly reduce the operational cost associated with the corrosion of metal pipes.

Features of EVAL™ EVOH:
▶ An outstanding barrier to gases: O₂, CO₂, H₂S, CH₄
▶ Excellent barrier to hydrocarbon vapors
▶ Excellent fuel barrier
▶ Excellent chemical resistance to aromatic and chlorinated solvents

Key Benefits of EVAL™ EVOH:
▶ Corrosion resistant
▶ Low-cost alternative vs. engineering resins
▶ Easily co-extruded with HPDE or PP into a stand-alone pressure pipe or a pipeline for a host ferrous pipe
▶ Compatible with standard fusion equipment
▶ Long service life at moderate temperatures

Applications:
▶ Pipe Barrier

SentryGlas® Interlayer

SentryGlas® Interlayer for laminated safety glazing outperforms other current technologies in laminated glass. It offers five times the tear strength and 100 times the rigidity of a conventional PVB interlayer. Because of its added strength, clarity, durability, fabrication and installation ease, it is an excellent candidate for demanding applications where sight is key.

Key Benefits of SentryGlas® Interlayer:
Safety: In the event of breakage, glass fragments remain firmly bonded to the interlayer reducing the chance for injury
Security: SentryGlas® glazing survives hurricane-force winds and a range of other threats
Durability: SentryGlas® interlayer is extremely durable and resistant to clouding, even after years of exposure
UV Control: SentryGlas® interlayer is available with or without UV transmittance

Applications:

▶ Safety glass for rigs, refineries, tankers, and ships
▶ Hurricane Glass
▶ Transportation Glass
▶ Security Glass

KURARAY POVAL™ PVOH for Well Construction

KURARAY POVAL™ PVOH, when mixed with cement powder, water, dispersant and defoamer, will prevent fluid loss to the formation in cementing operations. KURARAY POVAL™ PVOH is an excellent binder, reduces fluid loss, reduces water production in the cementing process, and is compatible with other cement additives. It contributes to cost savings by enabling fast and cost-efficient oil well construction and has shown no retardation effect on the cement setting time.

Key Benefits of KURARAY POVAL™ PVOH:
▶ Reduces fluid loss during cementing up to 150°F
▶ Lower cost than other fluid loss additives
▶ Does not retard the set-time at bottom-hole circulating temperatures
▶ Good compatibility with other cement additives
▶ Improves rheological properties

Applications:
▶ Additive for oil well-cementing operations

KURARAY LIQUID RUBBER & SEPTON™ Elastomers

Our research and development teams have pioneered a range of elastomer grades fit for the unique challenges of the oil and gas industry.

KURARAY LIQUID RUBBER grades function as reactive plasticizers but have a higher molecular weight than normal plasticizers. Used during the rubber compounding phase they significantly reduce processing time, while maintaining the rubber compound’s physical properties.

SEPTON™ thermoplastics act as modifiers and additives in applications such as plastic modifiers, compatibilizers, modification of thermosetting resins or shrinkage control for unsaturated polyester resins. Using elastomers in drilling fluid makes it less flammable, improves freeze resistance, and can be used in various layers of the earth’s crust.

Key Benefits of Kuraray Elastomer Products:
▶ Thermal and chemical superiority
▶ Extreme low-temperature capabilities
▶ Less hazardous in drilling fluids due to the lower flammability
▶ Reduced variation of viscosity with temperature change
▶ Better insulation abilities

Applications:
▶ Flexible Hoses
▶ Rubber Molded Compounds
▶ Sealing Solutions
▶ Oil Spill Clean Up
▶ Drilling Fluid Modification

Vectran™ Fiber

Vectran™ is a high-performance multi-filament yarn spun from liquid crystal polymer (LCP). Vectran™ fiber exhibits exceptional strength and rigidity. Pound for pound, Vectran™ fiber is five times stronger than steel and ten times stronger than aluminum.

The strength and stiffness of Vectran™ fibers satisfy demand for smaller, lighter ropes and cords. Vectran™ fibers enhance product durability with excellent resistance to both creep and flex fatigue, creating more efficient and longer-lasting ropes and cordage.

Key Benefits of Vectran™ Fiber:
▶ High tensile properties which provide thinner cables with high strength and stiffness with low elongation.
▶ Superior abrasion resistance in rugged locations.
▶ Vectran™ fiber helps to maintain strength after multiple reeling cycles or twisted deployments.
▶ Less time-dependent elongation of load-bearing fibers.
▶ Vectran™ fiber reduces blistering during extrusion of coatings and jackets.

Applications:
▶ Mooring Cables
▶ Sensor Cables
▶ Umbilicals
▶ Utility Ropes
▶ Deepwater Lifting

Genestar™ Coatings

Why Genestar™ PA9T? The issues seen with traditional pipe and liners are corrosion, gas permeation, and limited temperature ranges. Genestar™ PA9T is a performance polymer used for coating pipes and flexible tubes in oil and gas applications. Genestar™ PA9T shows superior performance in terms of water absorption, and heat and chemical resistance.

Advantages of Genestar™ PA9T:
▶ The gas barrier performance of the Genestar™ layer meets the specification requirements for flexible pipe design API 17J.
▶ The Genestar™ PA9T layer creates a barrier with low permeation to CO₂, H₂S, and other gases, protecting liners and pipes from corrosion under extreme conditions such as high temperatures (60°C – 120°C) and high pressures.

Applications:
▶ Pipes
▶ Liners
▶ Umbilicals

Kuraray's Advanced Chemicals

Kuraray’s SAL is a multi-purpose FeS inhibitor as well as a H₂S and mercaptan scavenger used by the oil and gas industry. Kuraray’s SAL  slows down or prevents FeS from depositing in the production tubing or on the pipe wall, and accumulating in separators.

Kuraray’s NL/MOL is an oil-soluble H₂S scavenger for the treatment of oil and gas. Kuraray’s NL/MOL used in production facilities reacts selectively with and removes H₂S to help meet specifications of the oil and gas industry.

Applications:
SAL: ▶ Clean up FeS
NL/MOL: ▶ Crude Oil Treatment ▶ Gas Treatment
