From the perspective of the market competition landscape, the market for bottle-grade high-viscosity polyester chips is highly competitive and exhibits a certain degree of market concentration. For example, Sinopec, as a long-term leader, possesses profound resources and production capacity in the polyester industry. Although it faces competitive pressures from new entrants, it is expected that through continuous technological innovation and adjustments to market strategies, its market share in the high-viscosity polyester chip market will remain stable and may even increase slightly.

An international enterprise has secured a place in the market with its advanced production technology, high-efficiency environmental protection facilities, and continuous product line expansion. With the growing demand for green products, it is likely to further increase its market share and ranking.

Some domestic enterprises have rapidly emerged in the high-viscosity polyester chip market by investing in research and development and optimizing production processes. It is expected that their market shares will increase significantly in the next few years.

Producers of virgin polyester chips also face a similar competitive environment and need to continuously enhance their competitiveness to establish themselves in the market.
