Prices are at the bottom, inventories are falling for the first time, and future demand is expected to pick upThe market price of glass fiber bottomed out, and the price of electronic yarn rebounded. In the alkali-free yarn market, as of November 11, 2022, the average price of 2400tex winding direct

1. What is pultrusion Pultrusion is a continuous process of manufacturing scrap with constant cross-section. Combining "pull" and "squeeze", pultrusion stretches the material as opposed to the extrusion that pushes the material.

In 2022, the market concentration of glass fiber is relatively high, and the competitive advantage of leading enterprises is expanding Glass fiber (referred to as fiberglass) refers to an inorganic non-metallic material made of pyrophyllite, kaolin, etc. as raw materials, through high temperature me

Domestic: The price of roving is loose at a high level, and the price of glass fiber yarn has bottomed out and rebounded. In terms of roving, as of July 22, 2022, the average price of alkali-free glass fiber roving was 6,117 yuan/ton, with a monthly increase of -332 yuan/ton; the average price of medium-alkali glass fiber yarn was 5,900 yuan/ton, and the price remained unchanged this month. ; The average price of direct yarn is 5650 yuan/ton, and the monthly increase is -350 yuan/ton. Due to the centralized production of new production capacity, the price of roving is loose at a high level.

The majority of artisan concrete projects, including concrete countertops, architectural panels, concrete vanities, and concrete furniture pieces often achieve their primary reinforcement using fiber technology. Understanding which fibers are functional as primary reinforcement, and the reasoning behind which fiber to use in a given situation, is helpful in achieving a well reinforced object. Three of the reinforcing fibers materials that are the most widely used are Alkali Resistant Glass Fibers, PVA Fibers, and AC50 Acrylic Fibers. There are many other fibers that are available, including nylon and polypropylene, but these are typically used for shrinkage control and secondary reinforcement, not as a primary reinforcement. For now we will focus on the benefits and drawbacks of using Alkali Resistant Glass Fibers.

Fiberglass is a form of fiber-reinforced plastic where glass fiber is the reinforced plastic. This is the reason perhaps why fiberglass is also known as glass reinforced plastic or glass fiber reinforced plastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight,
