Impact-modified
Polypropylene
Impact-modified PP for parts that take hits.
PiroPrene is a family of injection- and extrusion-grade polypropylene compounds — impact-modified, optionally talc-filled, optionally FDA-pathway. The workhorse PP grade for converters who need consistent rheology and a real engineer on the spec call.
