Take an Overview of Polyester Resin

What Is a Polyester Resin

Polyester resin is a general term for polymer compounds formed by polycondensation of diols or diacids or polyols and polyacids. Polyester resin is divided into saturated polyester resin and unsaturated polyester resin.

Examples of Polyester Resin

• Water Soluble Polyester Resin

It is the most common polyester resin. It is a type of adhesive that can be dissolved in water. This makes it easy to use and helps it bond well with various materials. It is often used in crafts and other DIY projects and for repairing things around the house. They are water-based dispersions of polymer in an organic solvent. Water-soluble polyester resins can be used to make a water-clear acrylic adhesive with many uses, from bonding woodturning to fixing cracks in bathroom tiles.

• Water Based Alkyd Resin

It is a substance obtained by a reaction of polyols with poly acids by esterification, they are considered polyester resins that can be modified by adding other components, such as fatty acids, this resin is a derivation of polyols and organic acids, among which are dicarboxylic acids, or anhydrides of these acids, and triglyceride oils.

What Are the Properties of Polyester Resin

Polyester resins are the most common type of Ashland resin, and they're also the most affordable. Polyester resins are solid and durable, making them a good choice for projects that require a high level of strength. However, polyester resins are not as resistant to heat as other types of Ashland resins, so they may not be the best choice for projects that will be exposed to high temperatures. Polyester resins are the least expensive and most widely used type of Ashland resin. They are typically used in lower-strength applications such as boat hulls and countertops.

Polyester Resin Market Analysis

◇ Major Raw Material of Polyester Resin is Increasing

It is worth mentioning that, in addition to PTA, Neopentyl Glycol, another major raw material of Polyester Resin, also rose sharply. Neopentyl glycol is a chemical product with isobutyraldehyde as the main raw material. Its main use is polyester resin. The end products are found in the fields of automobiles, textiles, medicine, coatings, pesticides, plastics, and petroleum. Take Wanhua Chemical’s Neopentyl Glycol price as an example. On July 26, Wanhua Chemical’s neopentyl glycol was raised by 500 yuan per ton, and the price was 20,300 CNY/ton. The current price is RMB 19,900/ton at the beginning of the month, an increase of 2%, and RMB 14,300/ton at the beginning of the year, an increase of 42%.

◇ The Supply of Polyester Resin is Tight

The supply of polyester resin is tight, and the sale of the stock is closed. The soaring price of neopentyl glycol has directly caused the price of polyester resin to invert. If the latest quotation is used to calculate the cost, the price of polyester resin will have to rise by 2,000 CNY/ton to absorb the increase in neopentyl. At present, the market price of polyester resin has reached between 17000-17800 CNY/ton, and there is still room for growth in the future. The downstream polyester resins are mainly powder products. At present, the supply of polyester products is tight, and there is a situation of queuing for orders.

◇ Traditional Peak Season is Difficult to Boost the Market Confidence

"Gold nine, silver ten" traditional peak season is difficult to boost the market confidence of polyester resin industrial chain, most of the raw materials collective into the downward channel. The lack of confidence in the industrial chain, operators' enthusiasm for trading is low, the market trading atmosphere is deadlocked, the value of crude oil crash in November, further aggravating the negative atmosphere of the raw material market.

At last, we hereby introduce a good supplier to you-Shandong Qibang Resin Co.,ltd. It is located in Linzi, Shandong. The factory is in the Qilu Chemical industry district close to the famous Qilu Petrochemical Ethylene Plant. The factory was founded in Sep 30th, 2006. To meet the market demand, the company built Branch company with investment of 500 million Yuan in 2009 which next to "CNOOC" Ethylene Plant in DongYing large oil refinery. The main products are C5 and C9 petroleum resin (Solid and liquid), which are used for rubber, tires, hot melt glue, road mark, bonding adhesive areas.
