In June, benzene collar company plans to increase PS profit
Rotary Rings are a type of rotating seal widely used in various rotating equipment, such as rotary joints, rotary couplings, rotary connectors, etc. Its main function is to prevent liquid or gas leakage and maintain the normal operation of the equipment. In different applications, the material, structure, sealing method, size, etc. of Rotary Rings vary to adapt to different working conditions.
The materials of Rotary Rings are mainly divided into two categories: metallic and non-metallic.
Metal materials mainly include stainless steel, steel, copper, aluminum, etc., which have characteristics of high strength, corrosion resistance, wear resistance, and are suitable for rotary seals in harsh environments such as high temperature, high pressure, and high-speed.
Non metallic materials mainly include ceramics, silicon carbide, graphite, etc., which have characteristics such as high hardness, high wear resistance, and low friction coefficient. They are suitable for rotary seals under conditions such as low temperature, low pressure, and high speed.
The Rotary Rings with a unidirectional rotation structure can only rotate in one direction and are suitable for devices with only unidirectional rotation.
The Rotary Rings with a bidirectional rotation structure can rotate in two directions, suitable for devices that require bidirectional rotation.
The Rotary Rings with a rotating stationary structure are composed of a rotating ring and a stationary ring. The rotating ring contacts the stationary ring during rotation to achieve sealing, suitable for equipment that requires a rotating stationary seal.
The sealing methods of Rotary Rings are mainly divided into mechanical sealing and liquid sealing.
Mechanical sealing is achieved through the contact surface between the rotating ring and the stationary ring, which has the characteristics of high reliability, long service life, and simple maintenance. It is suitable for rotary sealing in harsh environments such as high speed, high temperature, and high pressure.
Liquid sealing is achieved by injecting liquid between the rotating ring and the stationary ring, which has the characteristics of good sealing performance, low friction coefficient, and preventing dry friction. It is suitable for rotary sealing under low speed, low temperature, low pressure, and other conditions.
The size of Rotary Rings is mainly determined by the equipment requirements, including inner diameter, outer diameter, thickness, shaft diameter, etc.

The contract price of styrene in North-West Europe was set at 1,360 euros/ton FOB Europe ARA three port ($1,850/ton), down 45 euros/ton from May. The May FD North-West European contract price was €1,395/tonne. After announcing a price reduction of 35 euros/ton for GM, Benzene made another statement, saying it plans to increase global profits by 10 euros/ton.
In addition, the company said its high-impact PS resin will rise by €105/tonne in June.
According to market sources, the decline in both PS and styrene prices reflects the decline in raw material costs and the weak market fundamentals.
The contract price of benzene in northwestern Europe was determined at 977 euros/ton ($1,330/tonne) on CIF Europe ARA three ports on Friday, down by 71 euros/ton ($119/ton) from May. The price in May was 1,048 euros / ton (1,449 US dollars / ton) CIF Europe ARA three ports.
“In fact, the outlook for the PS market is still unclear, and the cost of raw materials has dropped by 50-55 euros/ton. The only thing that can be expected is that supply will be tight due to a series of equipment overhauls,†one buyer said.
One producer acknowledged that PS has become the weakest link in the styrenics industry chain due to weak demand in three major consumer sectors. However, EPS is surprising, with a double-digit market share.
The decline in PS prices in June contrasted with the increase in the contract price of PS in May. According to Platts data, the North West European general-purpose PS offer rose from €1,545/tonne in April to €1,565/tonne FD Northwest Europe.
PS resins are used in a wide range of applications, including the construction and automotive industries.
