Ultra-tough Makroblend® for the toughest applications
Covestro unites the superior properties of polycarbonate and polyester to give you Makroblend®. It's a family of materials ulta-tough enough for ski equipment, automotive spoilers, lawn and garden equipment, housings for medical, electrical and electronic devices. And a whole lot more.
Makroblend® resins have a property profile that includes high toughness (even at low temperatures); good chemical resistance to many lubricants, solvents and cleaning agents; reduced susceptibility to stress cracking; great paintability and low moisture uptake. Makroblend® resins also offer rigidity with a high tensile modulus of 1,900 to 3,900 MPa, depending on grade. The material has proved its toughness in applications for the lawn and garden, sporting goods, electrical and automotive industries. There also mineral-filled Makroblend® grades with a low coefficient of linear thermal expansion (CLTE) and an excellent surface, which is required for automotive exterior parts like spoilers. Eco-Compliant flame-retardant grades (non-halogenated flame retardant grades) are also available.
