STORAGE AND HANDLING: At Emerald Kalama Chemical’s production facility, the K-FLEX® plasticizers are
stored in type 304 stainless steel un-insulated storage tanks. These storage tanks are nitrogen padded to
reduce discoloration of the product. Type 304 stainless steel pipe and valves are also used. High density
polyethylene has been shown to be suitable for product shipment but we have no direct experience in
piping systems. Since K-FLEX ® products are excellent plasticizers for polyvinyl chloride (PVC); PVC piping
systems should not be used. Sliding vane type positive displacement pumps have given us excellent
service. Our engineers are always ready to discuss the storage and handling of any of our products.

Emerald Kalama Chemical is Division of Emerald Performance Materials, a manufacturer of additives and polymers which make

K-FLEX® Dibenzoate Plasticizers and
Coalescents
Products Available
K-FLEX® DE - shows excellent viscosity response when formulated into PVA and EVA emulsions. Although
solidifying at about 20˚C, it does not freeze in the formulated form.
K-FLEX® DP - the most versatile product in the K-FLEX plasticizer product line. In addition to its use in
adhesive applications, K-FLEX DP is a primary plasticizer for PVC resins. K-FLEX DP has additional uses in
personal care and as an inert carrier for pesticides. It has the lowest solidification temperature of any of the
K-FLEX dibenzoate esters, tending to form a glass or a super cooled liquid at around - 30° C (- 22°F).
K-FLEX® 500 - the most widely used of the K-FLEX plasticizers in adhesive applications. It is an excellent
choice for use in latex adhesives and caulks, hot melt adhesives, a variety of coating applications and PVC
formulations. K-FLEX 500 is a very good alternative to fast-fusing phthalates. K-FLEX 500 does not have a
simple freeze point but tends to form a super cooled liquid at around 0° C (32°F).
K-FLEX® 800 - widely used in adhesive applications. It is an excellent choice for use in latex adhesives and
caulks, hot melt adhesives, and in a variety of coating applications and PVC formulations. Like K-FLEX 500,
K-FLEX 800 is a very good alternative to fast-fusing phthalates. This product is specially formulated to meet
the labeling requirements for materials carrying the R52/53 designation of the European Union legislation
67/548/EEC. K-FLEX 800 retains the viscosity enhancing characteristics of K-FLEX DE for PVA and EVA
emulsions while exhibiting improved resistance to freezing while in storage.
K-FLEX® 850S- widely used in price-sensitive applications. It is an excellent choice for use in latex
adhesives and caulks, hot melt adhesives, and in a variety of coating applications. K-FLEX 850S is specially
formulated to meet the labeling requirements for materials carrying the R52/53 designation of the European
Union legislation 67/548/EEC. K-FLEX 850S retains the viscosity enhancing characteristics of K-FLEX DE
for PVA and EVA emulsions while exhibiting improved resistance to freezing while in storage.
