Glass fiber is a kind of inorganic nonmetallic material with excellent performance. It is often used as reinforcing material in composite materials and is used in aviation, transportation, wind power and building materials. 

According to the Glass Fiber Association, about 35-40% of buildings ,18% of transport ,14% of electronic devices ,11% of pipes.Recently, glass fiber set off a tide of price increases, causing widespread concern in the industry. 

A number of glass fiber enterprises have issued price increases announcement market demand is strong, glass fiber price rise natural.From the market demand, according to industry insiders, the price increase is due to strong wind power, resulting in supply exceeds supply. Glass fiber has the properties of light weight and corrosion resistance. It is a high quality raw material for wind power blade. Affected by wind power subsidy policy, onshore wind power project construction accelerated, blade manufacturers supply demand increased, glass fiber demand also benefited from growth.

In 2019, the supply and demand of the pool kiln yarn market was obviously out of balance, the product price fell sharply, the annual cumulative production capacity of the closed pool kiln was nearly 400000 tons, the upstream supply inventory was insufficient, and the price of the pool kiln yarn had been raised recently, especially the wind turbine demand. At present, domestic demand is boosted, the margin of foreign orders is improved, and the inventory of leading enterprises is lower than that of the previous period. With the arrival of the peak demand season and the approaching inflection point of the foreign epidemic situation, the glass fiber price ushered in the bottom upward inflection point.

In addition, glass fiber can be used in the field of transportation, such as high-speed rail, ships, highways and so on. Glass fiber reinforced plastics weigh 1/3 of steel and can effectively replace parts of cars and reduce weight, especially for new energy vehicles.

From the current situation of the industry, most enterprises maintain a production and sales rate of more than 100% in May and June, and the head enterprise inventory is down 10-15 days compared with April. With the gradual balance of supply and demand, the price increase of glass fiber industry has come to an end.

At the 2020 semi-annual briefing, the general manager of China Stonehenge believes that glass fiber prices have stabilized since June and rebounded in August. In the next two years, a new window of steady growth begins to open.
