ISO 180 (Izod Impact)
Pendulum impact test on a notched or unnotched specimen. Reported in kJ/m². Distinguishes brittle GPPS from impact-modified HIPS or ABS.
Why it matters for procurement
Understanding iso 180 (izod impact) matters whenever you need to translate a producer's technical data sheet into a procurement specification. Misreading the term can result in pricing the wrong material or accepting a non-compliant lot.
When you submit an RFQ, naming the relevant standard or property explicitly (rather than relying on a generic equivalent) reduces re-quote cycles and accelerates routing to the supplier with the matching grade in stock.

Homopolymer vs Copolymer
Homopolymers polymerise a single monomer (e.g. PP-H = pure propylene). Copolymers add a second monomer (PP-R random, PP-B impact) for clarity, toughness or processing.
