What is ISO 9113 - Isotactic index of polypropylene (PP) and propylene-copolymer thermoplastics about ?
ISO 9113 discusses plastics. ISO 9113 specifies a method for determining the percentage of matter which can be extracted from crystalline propylene plastics by boiling n-heptane under standard conditions of testing. The isotactic index is determined by conventional chemical extraction as an absolute method. This method provides for the identification and coding of types H, B and R propylene plastics according to ISO 190691. This method starts with solid propylene plastics in the form of particles of specified fineness. Note: This method is suitable only for base polymers and is not applicable for mixtures.
