STANDARD PROFILES PolYetHYLENE
Due to the high viscosity of the ultra high molecular weight polyethylenes (low MFI melt flow index), it is not possible to manufacture them by conventional injection or extrusion machines. Thus all LA brand profiles are manufactured from semi-finished products (pressed boards) obtained by sintering and melting the powder (polyethylene granulate) in computer presses at specific pressures and at high press times. The molecular weight of the various grades of polyethylenes used in the manufacture of the profiles may range from 5,000,000 to 9,000,000 g / mol from TIVAR® 1000 to TIVAR® TG1.
