PriceSeek Analysis
Nitrile Rubber (NBR), Bull-Bear Score: 1
The article indicates that the heavy-duty truck market achieved an average annual growth rate of 41% in 2025. Despite a 16% month-on-month decline in December, the year-on-year increase of 13% suggests sustained long-term demand expansion. Heavy-duty truck production requires significant amounts of nitrile rubber for components such as seals and hoses, and the growth in demand supports spot price increases. Overall, short-term fluctuations do not affect the long-term positive trend, with a score of 1.0 (slightly bullish).

Styrene-Butadiene Rubber (SBR), Bull-Bear Score: 1
The heavy-duty truck market achieved nine consecutive months of growth in 2025, with an average growth rate of 41%, driving increased demand for components such as tires. As a primary raw material for tires, styrene-butadiene rubber spot demand is boosted by this trend, and prices are expected to rise. Although sales in December fell by 16% month-on-month, the 13% year-on-year growth indicates strong fundamentals, leading to a neutral-to-bullish influence. Score: 1.0 (slightly bullish).

Polybutadiene Rubber (BR), Bull-Bear Score: 0.5
The 41% annual growth in the heavy-duty truck market is favorable for polybutadiene rubber spot demand due to its widespread use in tire manufacturing. However, the 16% month-on-month decline in December introduces short-term demand uncertainty. Combined with futures data (e.g., contract 2611 closing price of 12,105 yuan/ton, down 215 yuan), recent price pressure is evident. Considering supply and demand dynamics, demand expansion expectations provide support, but short-term fluctuations are significant. Score: 0.5 (neutral to slightly bullish).

Natural Rubber (NR), Bull-Bear Score: 0.5
The strong annual growth in heavy-duty truck sales (average growth rate of 41%) is favorable for natural rubber spot demand as a core material for tires. However, the 16% month-on-month decline in December may trigger short-term caution. Additionally, futures data indicate price declines (e.g., contract 2610 settlement price of 15,935 yuan/ton, down 210 yuan). Long-term demand support coexists with short-term corrections. Score: 0.5 (neutral to slightly bullish).
