What is the difference between polycarbonate and acrylic?

Polycarbonate offers 250 times the impact strength of glass and 30 times stronger than acrylic, making it virtually unbreakable for safety applications. Acrylic provides superior optical clarity and costs 30-40% less than polycarbonate but is more brittle. Choose polycarbonate when impact resistance is critical; select acrylic when clarity and weather resistance matter most.

Which plastics are FDA compliant for food contact applications?

FDA-compliant plastics meeting 21 CFR 177 regulations include natural UHMW polyethylene, white acetal copolymer, FDA-grade HDPE, polypropylene, clear polycarbonate, and acrylic. Port Plastics provides material certification documentation confirming FDA compliance with every shipment.

What temperature can PEEK plastic withstand?

PEEK maintains continuous service at temperatures up to 480°F (250°C) and can withstand short-term excursions to 570°F (300°C) without degradation. PEEK retains 90% of its room-temperature tensile strength at 300°F and performs in extreme cold to -40°F without becoming brittle.
