Indian PS prices

PS prices declined again in the Mumbai market this week as domestic trading sentiment remained weak and buyers stayed cautious about fresh procurement activity. Market assessments placed PS at Rs 171.00/kg compared with Rs 173.00/kg in the previous week, extending the broader downward trend observed during recent sessions. Indian PS prices have therefore continued to move lower amid reduced upward momentum and cautious market participation.

Monthly comparisons show that PS has fallen by Rs 11.00/kg over the past month, while three-month analysis indicates a decline of Rs 7.00/kg from earlier trading levels. Even with the recent correction, six-month trends remain significantly stronger, with prices still higher by Rs 51.00/kg compared with the low of Rs 120.00/kg. Year-on-year comparisons also indicate a rise of Rs 57.50/kg from Rs 113.50/kg. Indian PS prices continue to trade close to support at Rs 170.00/kg, while resistance remains around Rs 173.00/kg. PS prices in India currently reflect cautious procurement planning and close monitoring of market volatility across domestic trading channels, PS Prices, Polystyrene, Mumbai Market, Chemical Market, Petrochemicals, Commodity Trading.

Indian PS prices

PS prices in Delhi declined further this week as the domestic market extended the softer trend seen during the past month. The latest assessment closed at Rs 197.00/kg, compared with Rs 204.00/kg in the previous week, reflecting a weekly decline of Rs 7.00/kg. Indian PS prices have therefore continued moving lower amid cautious buying sentiment and moderate spot market activity. Traders reported that procurement decisions remained selective as downstream buyers evaluated current inventory positions and short-term consumption patterns.

Despite the latest correction, the broader market structure remains stronger than earlier periods. The current level is Rs 8.00/kg above the three-month average of Rs 189.00/kg, while Indian PS prices are also Rs 61.00/kg higher than the six-month comparison level of Rs 136.00/kg. On a year-on-year basis, the market is higher by Rs 64.00/kg from Rs 133.00/kg. The yearly range has fluctuated between Rs 129.00/kg and Rs 204.00/kg, reflecting continued volatility across the domestic segment. PS prices in India are now tracking support around Rs 189.00/kg, while resistance is observed near Rs 204.00/kg.

Solar energy transforms polystyrene waste into valuable chemicals using sulfur

Turning waste into wealth may no longer be just a marketing slogan, as a team of researchers in China has found an eco-friendly way to do exactly that. The abundant sunlight our planet receives was put to use for transforming polystyrene waste, one of the world's largest plastic polluters, into useful chemicals that can help advance the semiconductor industry. By adding elemental sulfur (S₈), they converted the plastic waste into two useful molecules: 2,4-diphenylthiophene and 1,3,5-triphenylbenzene. The first can be transformed into materials used in optoelectronics and high-performance semiconductors, while the second has a unique, rigid planar structure that makes it a great building block for creating advanced functional materials.

Indian PS prices

Polystyrene has posted another firm weekly move in Ahmedabad. HIPS was assessed at Rs 188/kg on March 16, up Rs 9/kg from March 14, and the latest gain follows a sequence of step-by-step increases that has lifted the market sharply through March.

Indian PS prices are now significantly above both fortnight and month markers. Compared with March 2, the market is higher by Rs 48/kg from Rs 140/kg, and the month view against February 14 shows the same Rs 48/kg increase. The short-term range has widened materially, with prices moving from the lower end near Rs 140/kg over the past month to the latest high at Rs 188/kg. On a three-month basis, the market is up Rs 59/kg from Rs 129/kg on December 16, while the six-month comparison against September 17 shows a rise of Rs 57/kg from Rs 131/kg. Indian PS prices have therefore shifted into a much firmer domestic structure than the one seen through late 2025.

PS prices in India are also well above the historical low around Rs 127/kg visible in the one-year series. Trading stayed flat at Rs 140/kg through March 5 before moving higher in stages to Rs 157/kg, Rs 161/kg, Rs 179/kg and finally Rs 188/kg. That sequence points to wider volatility than the narrow movement seen earlier in the month and leaves the market at the top of the current range, Polystyrene, Polystyrene Market, Polystyrene Prices, Polymer Market, Petrochemicals, Recent Peak.

Domestic PS market climbs to top of range

Polystyrene trading strengthened this week in the domestic polymer market as the benchmark moved sharply higher compared with the previous week’s level. The adjustment places the polymer near the upper side of the recent domestic trading corridor.

Indian PS prices were assessed at Rs 139/kg this week, rising from Rs 121/kg recorded seven days earlier. Over the broader domestic trading period, the polymer has moved between approximately Rs 109/kg and Rs 139/kg. Indian PS prices therefore now sit at the top of the observed range following the latest weekly movement.

Earlier sessions within the period showed smaller daily adjustments, keeping the benchmark within a narrower band before the latest increase expanded the weekly change. Procurement desks monitoring PS prices in India continue to track the benchmark closely as it approaches the upper boundary of the domestic corridor, Polystyrene, PS Market, Domestic PS, Polymer Prices, Petrochemical Market, Market Trend.
