Rokester® DP 3500.01 is a polyester polyol. It exists in the form of a viscous liquid. It has hydroxyl value within the range of 330-370 mgKOH/g, and dynamic viscosity up to the maximum of 600-1000 mPas at temp. 25°C.
Rokester® DP 3500.01 is an aromatic polyester polyol made from recycled raw material. It uses waste PET (polyethylene terephthalate) extracted from used plastic beverage bottles and other packaging.
PET (polyethylene terephthalate) is a plastic characterized by high levels of stiffness and hardness, as well as high mechanical and thermal strength. It is easy to process and maintains high shape stability. It is characterized by low water absorption and is resistant to corrosion and weather conditions.
Plastic waste lingers in the environment, releases a variety of harmful substances. These compounds, often highly toxic, enter the soil, air and water, disrupting the natural economy of entire ecosystems. Therefore, it is very important that as much PET waste as possible be recycled and used in the production of other raw materials or products.
As a raw material for polyester polyols, recycled PET requires remelting. The recycled PET pellets are heated and, with the help of appropriate catalysts and auxiliaries, converted into a liquid polyester polyol (in this case Rokester® DP 3500.01) that can be used to produce new polyurethanes.
Rokester® DP 3500.01 is a full-value product that can be used on a par with conventionally made products. It is characterised by low viscosity.
The product is mainly dedicated to the production of adhesives and two-component spray foam. Thanks to the content of aromatic groups, it allows for better flame retardant properties of spray foams.
PCC Rokita SA is one of the largest chemical companies in Poland as well as Central and Eastern Europe. Its activity includes the production of chloroalkali, polyether polyols, polyalkylene glycols and phosphorus derivatives.
