Impact Applications

Where K8303 Is Specified

High-impact copolymer grades are chosen wherever toughness under load matters.

Bumper Fascias Door Panels Dashboard Carriers Battery Casings Tool Cases Industrial Crates Lawn & Garden Housings
≥ 480 J/m
Notched Izod impact at 23°C for durable, impact-loaded parts
Processing

Processing Recommendations

Injection

Barrel 200-250°C; lower flow needs slightly higher pressure than high-MFR grades.

Mold Temp

30-60°C; warmer molds improve skin fusion and impact on ribbed parts.

Residence

Keep melt residence under 10 min above 240°C to protect the rubber phase.

Applications
