ISO 24022-1 is the first part of the multi-series ISO 24022 on PS moulding and extrusion materials. ISO 24022-1 establishes a system of designation for polystyrene thermoplastic material, which can be used as the basis for specifications.
The types of polystyrene plastics are differentiated from each other by a classification system based on appropriate levels of the designatory properties:
ISO 24022-1 applies to all amorphous polystyrene homopolymers. It applies to materials ready for normal use, unmodified or modified by colorants, additives, fillers, etc.
Note 1: ISO 24022-1 does not apply to expanded polystyrene, styrene copolymers, homopolymers of substituted styrene, or those modified with other polymers such as elastomers.
Note 2: It is not intended to imply that materials having the same designation give necessarily the same performance.
Note 3: IS0 24022-1 does not provide engineering data, performance data, or data on processing conditions that might be required to specify a material for a particular application and/or method of processing.
ISO 24022-1 on polystyrene is useful for:
Polystyrene plastic is a naturally transparent thermoplastic that is available as both a solid plastic as well in the form of a rigid foam material.
ISO 24022-1 specifies polystyrene plastics are differentiated from each other by a classification system based on appropriate levels of the designatory properties:
Using ISO 24022-1 guidelines, you will be in a position to take decisions about the suitability of a specified PS variant for your product.
