What does the price increase of fiberglass products (chopped strand mat) mean?

Fiberglass products followed the increase, and the industry's turning point signal was further strengthened. This price increase is the third round of price increases in the fiberglass industry since March 25 and April 13. The price increase mainly covers chopped strand mat products, while the previous two rounds of price increases were mainly for coarse yarn, fine yarn, and thin cloth. Chopped strand mat is a secondary product of fiberglass that is made by chopped fiberglass raw yarn into a certain length, randomly settling on a conveyor belt, and then bonding these chopped fibers together with a powder or emulsion adhesive. The raw yarn for making chopped strand mat is felt yarn, which is classified as twisted yarn. At the bottom of the fiberglass cycle in the past two years, felt yarn and sheet yarn were the most pressured fiberglass yarn varieties, and they were also the first fiberglass varieties to increase in price in this round. Against the background of the price increase of felt yarn, the profitability of fiberglass chopped strand mat is under pressure. This price increase belongs to the price transmission from yarn to products.
