Rokester® 2600 is a polymer from the group of aromatic polyester polyols. It exists in the form of a viscous liquid, a colour pale straw-to-olive liquid. It has a hydroxyl value within the range of 250-270 mg KOH/g and dynamic viscosity within the range of 2500-4500 mPas at temp. 25°C. It is characterized by relatively low and repeatable reactivity.
Rokester® 2600 is a raw material dedicated mainly to the production of one-component foams (OCF).
Rokester® 2600 is an aromatic polyester polyol produced from recycled PET (polyethylene terephthalate) with a minimum content of 28% in the product (EN ISO 14021:2016).
PET (polyethylene terephthalate) is a plastic characterized by high stiffness and hardness, as well as high mechanical and thermal strength. It is easy to process and maintains high dimensional stability.
It has low water absorption and is resistant to corrosion and weathering.
As a raw material for the production of polyester polyols, recycled PET requires remelting. Recycled PET pellets are heated and, with the aid of appropriate catalysts and additives, are converted into liquid polyester polyol (in this case, Rokester® 2600), which can be used to produce new polyurethanes.
Rokester® 2600 is a fully-fledged product that can be used on par with conventionally produced products. It is characterized by low viscosity.
The product is primarily intended for the production of one-component foam (OCF). Thanks to its aromatic groups, it enhances the flame-retardant properties of OCF foams. Rokester® 2600 is also used in closed-cell 2K spray systems.
