Polyol / Isocyanate(MDI)

Polyurethane is made by reacting two liquids. SK pucore supplies both sides — the polyol, which carries most of the formulation, and the isocyanate that cures it. What the finished foam does, whether it holds a driver in place for ten years or keeps a refrigerator cold, is decided in that formulation rather than in the moulding.

Materials

• Polyol — polypropylene glycol and polyol grades, the base of the formulation
• POP — polymer polyol, used where the foam has to carry load without going hard
• MDI — isocyanate, supplied as solution

Applications

Automotive — seat cushions, seat backs and headrests. Foam for a seat has to return to shape after years of use and stay within its original dimensions, which is a different requirement from comfort alone.

Furniture — sofa cushions and mattresses.

Insulation — rigid foam for heat insulation, including refrigerator cabinets, where the foam both insulates and stiffens the case.

Supply

Shipped in drums or by ISO tanker depending on volume. DIGILOGTECH runs this business for Southeast Asia, supplying producers in Indonesia.
