What is PP-C?
PP-C is propylene copolymerised with ethylene, supplied as impact (block) copolymer or random copolymer under ASTM D4101 (PP0220), with 25 MPa yield, 26 MPa tensile strength, 350 % elongation, 1.1 GPa modulus, Shore D 67 and 0.902 g/cm³ density. It is used where low-temperature impact resistance, living hinges or clarity matter more than stiffness — thin-wall moulded parts, appliance and automotive trim, and PP-R hot-water pipe. Peak service temperature is 95 °C, stiffness and heat resistance are below PP-H, and surfaces need activation before paint; PP-H is the alternative when rigidity governs. PP-C has a density of 0.9 g/cm³ (0.0326 lb/in³), lighter than 82% of polymer grades. Its glass-transition temperature is -18°C (-0.4 °F). PP-C has a yield strength of 25 MPa (3.63 ksi) and a tensile strength of 26 MPa (3.77 ksi) — weaker than 74% of polymer grades. Elongation at break is 350% and the elastic modulus is 1.1 GPa (0.16 Msi).

Working with PP-C
Is PP-C easy to machine?
Machines easily but is soft and gummy — use sharp, high-rake single-flute or O-flute tools, high speed with low feed pressure, air/mist cooling, and expect springback and burring; avoid clamping distortion.
Can PP-C be welded?
Excellent for hot-plate, hot-gas, spin, ultrasonic and IR welding and for extrusion welding of sheet/pipe with matching PP rod; adhesive bonding requires flame, corona or plasma pretreatment plus a polyolefin primer.
Can PP-C be formed, bent or molded?
Injection molds at 200–260 °C melt / 20–60 °C mold with 1.0–2.2 % shrinkage; keep uniform wall, use generous ribs (living hinges from RCP), and dry-free processing — but the narrow thermoforming window and high shrink demand careful gate/cooling design.
PP-C chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |

| ethylene (comonomer)random copolymer typ. 1–7 %; impact/block copolymer typ. 6–18 % present as dispersed EPR/EPDM phase | 1 – 20 | 9 |
| butene-1 (optional termonomer)used in some clarified random copolymers | 0 – 4 | 0 |
| stabilizers / nucleator / antistatphenolic + phosphite AO, acid scavenger, clarifier (sorbitol) or beta-nucleator | 0.05 – 1 | 0.3 |

| propylenepolymer backbone | balance |
What surface finishes work on PP-C?
Cannot be plated or anodized; paintable only after flame/plasma activation with adhesion promoter, so most parts rely on mold-textured or gloss surfaces, in-mold decoration, pad printing or laser marking.

PP-C — frequently asked
What is PP-C used for?
PP-C is typically used for automotive bumpers and interior trim, living-hinge containers, hot-water piping (PP-R), appliance housings, thin-wall injection molded parts and food packaging tubs. In short: impact-tough PP; living-hinge grade; cold-service polyolefin.
What is the yield strength of PP-C?
PP-C has a typical yield strength of 25 MPa (3.63 ksi) and a tensile strength of 26 MPa (3.77 ksi) — weaker than 74% of polymer grades. Strength varies by condition: see the 7 listed tempers.
Is PP-C easy to machine?
Reasonably — machinability is rated good (65/100, better than 66% of polymer grades). Machines easily but is soft and gummy — use sharp, high-rake single-flute or O-flute tools, high speed with low feed pressure, air/mist cooling, and expect springback and burring; avoid clamping distortion.
Can PP-C be welded?
Yes — weldability is rated excellent (88/100). Excellent for hot-plate, hot-gas, spin, ultrasonic and IR welding and for extrusion welding of sheet/pipe with matching PP rod; adhesive bonding requires flame, corona or plasma pretreatment plus a polyolefin primer.
What surface finishes work on PP-C?

What is the maximum service temperature of PP-C?
PP-C is rated for continuous use to about 95°C (203 °F), and briefly to 120°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between PP-C ICP and PP-C FR-V0?
ICP is the default condition — default choice when low-temperature toughness matters: automotive interior parts, crates, battery cases, thin-wall housings. FR-V0: electrical enclosures and appliance parts requiring UL 94 V-0 at 1.5–3 mm. Yield strength is 25 MPa in ICP versus 22 MPa in FR-V0.
How much does PP-C cost?
PP-C is a budget-cost polymer ($), cheaper than about 90% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
