Characteristics and application of glass fiber chopped strands

一、Glass fiber chopped strand properties

  1. Chopped fiberglass e-glass strands have good corrosion resistance. Because the main raw material of FRP is composed of unsaturated polyester resin and fiber reinforced material with high molecular content, it can effectively resist the corrosion of acids, alkalis, salts and other media, as well as untreated sewage, corrosive soil, chemical wastewater and many chemical liquids. Corrosion, under normal circumstances, can keep running for a long time.

  2. Alkali resistant fiberglass chopped strands have good anti-aging and heat resistance functions. The glass fiber tube can be used for a long time in the temperature range of -40℃~70℃, and the high temperature resistant resin with special formula can also work normally at the temperature above 200℃.

  3. Good anti-freeze function. Below minus 20 ℃, the tube will not freeze after freezing.
  Glass fiber chopped strand material classification
  One is glass plate, which is mainly used for the parts that need lighting in decoration. There are flat glass, patterned glass, frosted glass, coated glass, engraved glass, tempered glass, etc., which can be selected according to the requirements of different parts and different decorative effects. .
The other type is glass bricks, which are mainly used for glass partitions, glass walls and other projects, mainly hollow glass bricks. It can be divided into single-chamber and double-chamber, and has various specifications such as square brick and rectangular brick, and its surface shape is also very rich, which can be selected and used according to the needs of decoration.


二、The difference between glass fiber chopped strands and long fibers

  With the continuous development of the times, the related glass fiber production industry is also constantly improving, and the derivative products of related glass fibers are also constantly innovating and improving. High-quality short glass fibers are very popular in the modern market, and fiberglass filaments are no exception. The application fields of short glass fibers and long glass fibers are different, and they play different roles in different fields. The characteristics of short glass fibers and long glass fibers are different. The best short glass fiber companies in the industry supply short glass fibers that are well-received. So, what are the differences between short glass fibers and long glass fibers that are easy to use?

  1. Different physical lengths
Short glass fibers with good quality are in great demand in the market, as are long glass fibers. The physical length of short fibers is usually less than six millimeters, or even between 0.2 millimeters and 0.6 millimeters; while the physical lengths of long glass fibers are in the range of six millimeters to twenty-five millimeters. Easy-to-use short glass fiber will increase the customer's repurchase rate, and relevant short glass fiber manufacturers that are well-received will also increase the production of short glass fiber to ensure customer demand. Of course, better short glass fibers are usually more popular with customers.

  2. The production process is different
The production process of the well-received short glass fiber is different from that of the long glass fiber. In the production process of short glass fiber with good quality, the size should not be too long, but because of this feature, the easy-to-use 15 oz chopped strands are more flexible in production, with good quality and yield; while long glass fiber In the production process of the fiber, the fluidity of the material is required to be good, and the surface of the glass fiber should be activated, and the phenomenon of glass fiber peeling and leakage should not occur. The difference in production process between short glass fiber and long glass fiber leads to different fields of application.


三、Application of glass fiber chopped strands

  At present, glass fiber products can be basically divided into four categories, namely, glass fiber reinforced materials for reinforced thermosetting plastics, glass fiber chopped strands for reinforced thermoplastics, textile glass fiber chopped strands for electrical insulation and other purposes, and roofing waterproofing materials. Glass fiber chopped strands. Among them, Glass fiber chopped strands reinforcement accounts for about 70%-75%, and Fiberglass Fabric Materials accounts for about 25%-30%.
  There are more than 3,000 varieties of glass fiber chopped strands in foreign countries, with more than 50,000 specifications. In recent years, more than 1,000 specifications have been added every year on average. Foreign experts believe that the development speed of this variety cannot meet the market demand to a large extent, and it can only be regarded as the beginning of development.

Application of glass fiber chopped strands:

  Glass fiber filaments are divided into woven selvedge and non-woven selvedge (fringe tape). The main weaving method is plain weave.
  The three-dimensional fabric is relative to the flat fabric, so that the composite material with this reinforcement has good integrity and profiling, and greatly improves the interlaminar shear strength of the fiber glass raw material.
  Fiberglass chopped strand stitchbonded fabric is also known as Fiberglass Needle Mat or Fiberglass combo mat. It is different from ordinary fabrics and felts in the general sense. A typical stitchbonded fabric is a layer of warp yarns and a layer of weft yarns overlapped together, and the warp and weft yarns are stitched together to form a fabric.
  Unidirectional glass fiber chopped strand fabric is a four-warp broken satin or long-axis satin fabric composed of thick warp yarns and fine weft yarns. It has high strength in the main direction of the warp.
  Glass fiber chopped strands are commonly used as reinforcing materials for composite materials, electrical insulation materials, thermal insulation materials, circuit substrates, etc. Because it plays a very important role in many industries, it is more and more popular.
