High-Gloss, Scratch-Resistant Finish

POLYLAC PA-707’s mirror-like surface eliminates secondary painting, saving time and costs. Perfect for consumer-facing products like telephone casings or appliance buttons where aesthetics matter.

Ultra-Rigid & Dimensional Stability

With flexural strength of 79 MPa and low mold shrinkage (0.4–0.7%), this resin resists warping, ensuring precision in parts like clock casings or office supplies that require tight tolerances.

Heat & Impact Resilience

Survives harsh conditions: Vicat softening at 104°C and HDT up to 98°C for heat resistance, plus 13 kJ/m² impact strength at 23°C. Ideal for lamp seats near bulbs or toys subjected to rough handling.

Applications

Telephone Casings
Lamp Seats
Toys
Office Supplies
Clock Casings
Appliance Buttons
