Product Detail

Long glass fiber reinforcement compounds


Glass fiber is a kind of inorganic non-metallic material with excellent performance, a wide variety of advantages are good insulation, strong heat resistance, good corrosion resistance, high mechanical strength, but the disadvantage is brittle, poor wear resistance.

Glass fiber is glass ball or waste glass as raw materials by high temperature melting, wire drawing, yarn, weaving and other processes made of the monofilament diameter of several microns to more than 20 microns, equivalent to a hair 1/20-1/5, each bundle of fiber filament are composed of hundreds or even thousands of monofilament.

Glass fiber is usually used as reinforcement materials in composite materials, electrical insulation materials and thermal insulation materials, roadbed panels and other fields of the national economy.



The appearance is cylindrical with smooth surface, the section is complete circle, and the circular section has strong load bearing capacity; Gas and liquid passing resistance is small, but smooth surface makes the fiber holding force small, is not conducive to the combination with resin; The density is generally 2.50-2.70g /cm3, mainly depending on the glass composition; The tensile strength is higher than other natural fibers and synthetic fibers. Brittle material, its elongation at break is very small; Water and acid resistance is good, and alkaline resistance is poor.


PP (long fiber thermoplastic) is the most used basic resin for LFT, by PA, and PBT, PPS, TPU and other resins are also used.

From common consumer goods to consumer durables, plastics are ubiquitous in everyday life. To increase the strength of plastics, thermoplastic materials are usually reinforced with glass or carbon fibers. Faced with the impact stress under high loads and high temperature and low temperature conditions, traditional short glass fiber materials are often unable to match, in this case, the polymer begins to soften or become brittle, long glass fiber reinforced polymer came into being.


Long glass fiber generally refers to the length of 6-25mm glass fiber.

It is usually a cylindrical particle with a length of 12 mm or 25 mm and a diameter of about 3 mm. Among them, the particle with a length of about 12mm is mainly used for injection molding, while the particle with a length of about 25mm is mainly used for pressure molding.

In this particle, the glass fiber has the same length as the particle, the glass fiber content can range from 20% to 70%, and the particle color can be matched according to customer requirements.

As a vehicle module carrier material, the material can not only effectively improve the rigidity, impact strength, creep resistance and dimensional stability of the product, but also can make complex vehicle module products.

Advantages of long glass fiber compounds (compared with short glass fiber compounds)


Why do some areas use long glass fiber reinforced PP instead of short glass fiber reinforced PP?

• Long fiber length, significantly improve the mechanical properties of products.

• High specific stiffness and strength, good impact resistance, especially suitable for automotive parts applications.

• Improved creep resistance, good dimensional stability, high component forming accuracy.

• Excellent fatigue resistance.

• Better stability in hot and humid environments.

• The fiber can move relatively in the molding mold during the molding process, and the fiber damage is small.


The application of long glass fiber reinforcement Polypropylene


Automobile industry
Front end modules, door modules, shift mechanisms, electronic accelerator pedals, dashboard frames, cooling fans and frames, battery brackets, bumper brackets, underbody protection panels, sunroof frames, etc. are used to replace reinforced PA or metal materials.

Home appliance industry
Washing machine rollers, washing machine triangular brackets, one brush machine rollers, air conditioning fans, etc., used to replace short glass fiber reinforced PA, APS or metal materials.

Telecommunications, electronics, electrical industries
High-precision connectors, igniter components, coil shaft, relay base, microwave oven transformer coil frame/frame, electrical connectors, solenoid valve packages, scanner components, etc.

other
Power tool shell, water pump or water meter shell, impeller, bicycle skeleton, skis, ground locomotive pedal, military/civilian safety helmet, safety shoe head, etc., used to replace short glass fiber reinforced PA, PPO, etc.

Glass fiber has many advantages, such as high strength and light weight, corrosion resistance, high temperature resistance, good electrical insulation, etc., and is one of the commonly used composite materials. At the same time, China is also the world's largest glass fiber production country.
