Reliance PPCP Repol MI7035
Reliance Repol MI7035 is a polypropylene impact copolymer (PPCP) engineered for the high-speed extrusion compression moulding (ECM) process, making it the preferred material for moulded caps & closures where fast cycles, process reliability, and regulatory compliance are critical. MI7035 delivers the ideal combination of MFI (7 g/10 min), high flexural modulus (1300 MPa), robust impact strength (Izod 115 J/m), and thermal stability (HDT 115°C). Its natural colour and Shore D 68 hardness ensure both visual appeal and durability. MI7035 conforms to IS 10910, making it suitable for food and pharma contact applications.
