Features & Benefits

Superior Flow for Complex Molds

Apec® 1897’s high melt volume-flow rate (18 cm³/10 min) ensures effortless filling of intricate thin-walled designs, reducing cycle times and production costs for detailed parts like lens housings.

UV Resistance for Long-Term Clarity

UV stabilization prevents yellowing and degradation in outdoor exposure, maintaining optical transparency and extending the lifespan of automotive lamp covers and headlamp lenses.

High Heat & Dimensional Stability

With a Vicat softening temperature of 182°C and low molding shrinkage (0.85%), this resin withstands extreme temperatures while retaining shape—critical for components near high-heat sources like bulbs.
