Polypropylene price

The cost of propylene monomer is the main pillar of polypropylene economics. Propylene has traditionally been produced as a by-product of naphtha crackers, where ethylene is the main product, so supply depends on activity in the ethylene market. Propane dehydrogenation (PDH) plants, by contrast, produce propylene directly and have become a marginal cost-setter in regions where propane is cheap because of the shale gas boom. The expansion of Chinese PDH capacity has materially changed the global propylene balance: when the propane-propylene spread, or P-P spread, narrows, PDH plant utilisation falls. That tightens the monomer market and pushes PP resin prices higher.

Chinese demand is the second major factor. China accounts for about 30 percent of global polypropylene consumption and is also the largest producer. Demand rests on three pillars: the car industry, including bumpers, interior trim and battery housings in electric vehicles; textiles and nonwovens, including hygiene products, geotextiles and surgical masks; and packaging, including food, beverage and cosmetics packaging. Beijing’s property policy, Chinese vehicle production runs and the order book of the export-oriented textile sector all feed directly into Dalian Commodity Exchange prices.

Demand for automotive lightweighting and medical nonwoven fabrics is the third structural factor. A modern passenger car typically contains 80–100 kg of plastic, much of it polypropylene. Replacing metal parts reduces weight and fuel consumption, and increases range in electric vehicles. In the medical and hygiene segment, PP nonwovens made with melt-blown technology form the filtration layer in surgical masks, FFP2/FFP3 respirators and adult incontinence products. Epidemic cycles have therefore become a direct price factor.
