PP – Polypropylene

A polymer of ethylene with isostatic arrangement of methyl groups. It does not belong to the family of fluoroplastics. PP can be autoclaved (at +121 °C) and is distinguished by good mechanical and chemical properties almost up to its softening point. PP labware is unbreakable and an economical alternative with, however, restricted chemical and thermal resistance.



PS – Polystyrene

A polymerisation product of styrene. Polystyrene is one of the most commonly used plastic materials. For many years it has been processed by injection moulding, extruding or blowing. Because of its structure, it belongs to the family of amorphous thermoplastics and is transparent, inflexible and brittle. Polystyrene has a low thermal and chemical resistance. New developed PS-HI types provide an increased impact strength (HI = High Impact).
