Recycled HDPE (rHDPE) process: 6 steps from collection to pellets. Saves 88% energy vs virgin. Applications in pipes, bins, plastic lumber. Food contact limitations.

PP vs HDPE: PP has better heat resistance (160 vs 135°C), HDPE better cold performance (-40°C). Full comparison for pallets and industrial use.

HDPE continuous service limit 82°C, short-term max 120°C, cold limit -40°C. Full temperature range guide for HDPE in industrial applications.

HDPE MFI measured in g/10min at 190°C / 2.16kg. Pallet-grade HDPE typically 2-5 g/10min. How MFI affects processing and mechanical properties.

Plastic number 5 is Polypropylene (PP). BPA-free, FDA and EU food contact approved, microwave-safe when rated. Full guide to code 5 plastic.

PET vs PP: PET has better clarity, PP has better heat resistance (160 vs 120 degrees C). Full comparison for packaging and industrial use.

Clear PP sheet: chemical resistance, food safe (code 5), heat resistant to 120 degrees C. Applications in food, medical, and industrial packaging.

PP plastic can be recycled 4-10 times. Virgin PP products last up to 15 years. Full guide to PP lifespan and recyclability.

PP plastic melting point 160 degrees C, continuous service limit 82 degrees C. Full analysis of PP heat resistance vs PE, PET, PC.
