The sulfone polymer market is witnessing significant growth owing to rising adoption of these polymers in the medical industry for manufacturing various medical devices such as hemodialyzers, artificial kidneys, heart valves and drug delivery systems. Sulfone polymers exhibit excellent biocompatibility and do not leach harmful substances, making them suitable for use in contact with body fluids and tissues. Their chemical resistance allows sulfone polymers to withstand harsh sterilization processes like autoclaving and radiation sterilization. In addition, growing demand from the automotive industry is also driving the market as sulfone polymers are increasingly used in manufacturing automotive engine components owing to their heat resistance and electrical insulating properties.

Sulfone Polymer Market Restrain: High Production Cost

One of the key restrains hampering the growth of the sulfone polymer market is its relatively high production cost compared to alternate engineering thermoplastics. Sulfone polymers require specialized precursors and production processes that make their manufacturing a complex and expensive process.

The production of sulfone polymers starts with diphenyl sulfone, which needs to be reacted with bisphenol to form a polymer. This reaction requires specific reaction conditions and needs to be carried precisely to get high molecular weight sulfone polymers with consistent properties. The specialized equipment, tight process control and quality assurance measures involved lead to increased capital and production costs.

Additionally, sulfone polymers have low melt flow properties requiring higher processing temperatures that further add to the production energy costs. All these factors increase the per unit production cost of sulfone polymers, making them more expensive than other thermoplastics like PEEK, PEI and PPS. This high cost barrier limits their widespread adoption and restrains the market growth potential especially in cost-sensitive applications.
