|---|---|---|---|---|---|
Impact-modified (elastomer-toughened) PP homopolymer | Use where PP-H's notch and sub-zero brittleness is the limiting factor but homopolymer stiffness/cost is still wanted. | 25 | 26 | 450 | 64 Shore D |
flame-retardant PP homopolymer | Halogen-free or brominated FR compound for electrical housings and battery components requiring V-0 at 1.6 mm. | 26 | 26 | 15 | 70 Shore D |
ESD / conductive carbon-filled PP homopolymer | Carbon-black or carbon-fiber loaded compound for electronics trays, fuel-handling and explosion-risk areas needing static dissipation. | 29 | 30 | 6 | 74 Shore D |
