Fiberglass rods are widely used in agriculture, construction, electrical and other industries. the performance is very different such as high strength ,anti UV, insulation etc . Every performance are require different raw materials, Most of the fiberglass rods on the market cannot meet special requirements , if you need high strength fiberglass rod or something else you need to customize it , Our factory cover most of the general types of fiberglass rods. Below I will introduce the difference between them, and you will find the fiberglass rod you need here.
Fiberglass rod is made of fiberglass yarn and resin by mold heating and curing. At present, the main production process of fiberglass rod is pultrusion. The worker first calculates the number of yarn required according to the size of fiberglass rod, and then passes a fixed number of yarn through the forming mold Before passing through the mold, the yarn should be contaminated with a certain amount of resin. When the resin is brought into the mold, the resin solidifies due to the high temperature of the mold, thus forming the fiberglass yarn into fiberglass rod.
The length of the fiberglass rod is not limited, we even can make a rod with length more than 1000 meters, if the out diameter you need is not in the below list, please contact us directly !

The performance of fiberglass rods made from different raw materials varies significantly
E-Glass fiberglass rods are made from E-Glass fiberglass yarn. This type of fiberglass yarn is the most common and economical grade of fiberglass yarn. E-Glass fiberglass rods have moderate strength, good electrical insulation properties, and excellent corrosion resistance. They are widely used in construction, marine, and electrical industries for various applications, such as insulation, reinforcement, and structural components. The primary disadvantage of E-Glass fiberglass rods is their relatively low tensile strength and stiffness.
S-Glass fiberglass rods are made from S-Glass fiberglass yarn. This type of fiberglass yarn has higher strength and stiffness than E-Glass fiberglass yarn. S-Glass fiberglass rods have high tensile strength, excellent electrical insulation properties, and good corrosion resistance. They are widely used in aerospace, defense, and high-performance applications that require superior strength and stiffness. The primary disadvantage of S-Glass fiberglass rods is their relatively high cost.
C-Glass fiberglass rods are made from C-Glass fiberglass yarn. This type of fiberglass yarn has higher chemical resistance than E-Glass and S-Glass fiberglass yarn. C-Glass fiberglass rods have excellent corrosion resistance and are widely used in the chemical and petrochemical industries for chemical storage and transportation. The primary disadvantage of C-Glass fiberglass rods is their relatively low tensile strength and stiffness.
Epoxy fiberglass rods are made by combining fiberglass yarn with epoxy resin. These rods have high mechanical strength, excellent dimensional stability, and good chemical resistance. They are widely used in electrical and electronic industries for insulation, as well as in construction and aerospace industries. The primary disadvantage of epoxy fiberglass rods is that they are relatively brittle and can crack under impact.
Phenolic fiberglass rods are made by combining fiberglass yarn with phenolic resin. These rods have excellent electrical insulation properties, high mechanical strength, and good chemical resistance. They are widely used in the electrical industry for insulation, as well as in construction and marine industries. The primary disadvantage of phenolic fiberglass rods is their relatively low dimensional stability and high water absorption.
Polyester fiberglass rods are made by combining fiberglass yarn with polyester resin. These rods have high mechanical strength, excellent electrical insulation properties, and good chemical resistance. They are widely used in the electrical industry for insulation and in construction and transportation industries. The primary disadvantage of polyester fiberglass rods is their relatively low heat resistance and dimensional stability.
Vinyl ester fiberglass rods are made by combining fiberglass yarn with vinyl ester resin. These rods have high mechanical strength, excellent chemical resistance, and good heat resistance. They are widely used in the chemical and petrochemical industries for chemical storage and transportation, as well as in construction and marine industries. The primary disadvantage of vinyl ester fiberglass rods is their relatively high cost.
Besides the fiberglass yarn and resin, filler is also an important raw material
Talc is a common filler used in the production of fiberglass rods. Talc-filled fiberglass rods have good electrical insulation properties and are resistant to impact and abrasion. They are widely used in the electrical and construction industries for applications such as insulation and structural components. The primary disadvantage of talc-filled fiberglass rods is their relatively low tensile strength and stiffness.
Alumina trihydrate is a filler that is often used in fiberglass rods for fire-retardant applications. Alumina trihydrate-filled fiberglass rods have excellent fire-retardant properties and are widely used in the construction industry for applications such as fire doors and panels. The primary disadvantage of alumina trihydrate-filled fiberglass rods is their relatively low strength and stiffness.
Glass microspheres are a lightweight filler that is often used in the production of fiberglass rods. Glass microsphere-filled fiberglass rods have low density and are suitable for applications that require lightweight materials, such as marine and aerospace industries. They also have good insulation properties and are resistant to impact and abrasion. The primary disadvantage of glass microsphere-filled fiberglass rods is their relatively low strength and stiffness.
Light weight and high strength
The relative density is around 1.9, only 1 / 4 ~ 1 / 5 of carbon steel, but the tensile strength is close to or even better, and the specific strength can be compared with high-grade alloy steel. Therefore, it has excellent effect in the application of aviation, rocket, spacecraft, high pressure vessel and other products that need to reduce self weight. The tensile, flexural and compressive strength of some epoxy FRP can reach more than 400MPa.
Good corrosion resistance
FRP is a good corrosion-resistant material, which has good resistance to atmosphere, water, general concentration of acid, alkali, salt, a variety of oils and solvents. It has been applied to all aspects of chemical anti-corrosion and is replacing carbon steel, stainless steel, wood, non-ferrous metals, etc.
Good electrical performance
It is an excellent insulating material, used to make insulators. Good dielectric property can be protected at high frequency. Microwave transmission is good and has been widely used in radome.
Good thermal performance
The thermal conductivity of FRP is low, which is 1.25 ~ 1.67kj / (m · h · K) at room temperature, only 1 / 100 ~ 1 / 1000 of metal, so it is an excellent thermal insulation material. In the case of instantaneous ultra-high temperature, it is an ideal thermal protection and ablation resistant material, which can protect the spacecraft from the erosion of high-speed airflow above 2000 ℃.
Good designability
Excellent technology
Because of its unique performance advantages, fiberglass rods have been widely used in more than ten industries, such as aerospace, railway, decorative architecture, home furniture, advertising display, craft gifts, building materials and sanitary ware, yacht berthing, sports materials, environmental sanitation engineering and so on, and are highly praised. They have become the demand pet of businessmen in the material industry in the new era.
