Flame Retardant PEEK Fill Long Carbon Fiber Reinforced Plastic General Grade

Product information

Polyether ether ketone (PEEK) is a polymer composed of one ketone bond and two ether bond repeating units in the main chain structure. It is a special polymer material. 

With high-temperature resistance, chemical corrosion resistance, and other physical and chemical properties, is a kind of semi-crystalline polymer material, that can be used as high-temperature resistant structural materials and electrical insulation materials, and can be prepared with glass fiber or carbon fiber composite reinforcement material. 

A class of polyaryl ether polymers is generally obtained by condensation with aromatic binary phenols. The material has numerous applications in aerospace, medical devices (as an artificial bone to repair bone defects), and industry.

Product datasheet

PEEK resin also has large rigidity, good size invariance, a small linear expansion coefficient, very close to metal aluminum material. Easy injection molding, extrusion molding, good processing performance, high molding efficiency.

Product application

1. Aerospace filed

Aerospace is PEEK's earliest application area. The general trend of lightweight, reducing CO2 emissions and accelerating processing support the use of PEEK composites in the aerospace sector. The particularity of the aviation field requires flexible processing, low processing cost, and light materials resistant to harsh environments. 

PEEK has many advantages in this field, such as high-temperature resistance, excellent machining, radiation resistance, low smoke, flame retardant, non-toxic, corrosion resistance, hydrolysis resistance, and so on. As a result, PEEK can replace aluminum and other metals to make various aircraft parts, which can be up to 70% lighter than metal and improve fuel efficiency.

2. Medical filed

PEEK has the advantages of non-toxicity, excellent biocompatibility, lightweight, and corrosion resistance, so it is a potential biological prosthesis material.

According to Mapp Medical Research, PEEK material has been approved by FDA (Food and Drug Administration) for market application in bone transplantation. It has effectively solved the problems of traditional titanium materials such as thermal expansion and cold contraction, fast thermal conductivity, and metal artifacts, and has become the first choice of titanium materials.

3. National defense materials

PEEK has been used as an important strategic defense material since its invention. Due to the characteristics of PEEK resistance to high and low temperatures, easy hydrolysis, radiation resistance, etc., cables, wires, coil skeletons, connectors, and valves have been successfully applied to nuclear power plants, oil exploration, and the exploitation industry.

Frequently asked questions

Q:

The product is easy to brittle, so does change to use long fiber-reinforced thermoplastic materials can solve this problem?

A:

The overall mechanical properties must be improved. The characteristics of long glass fiber and long carbon fiber are the advantages of mechanical properties. It has 1-3 times higher (toughness) than short fiber, and the tensile strength (strength and rigidity) is increased by 0.5-1 times.

Q:

After the long glass fiber is reinforced, the glass fiber content of the material increase. The resin fat solubility reduces the flow performance, and the injection pressure is much higher than that without the glass fiber. How to solve the problem of poor molding and lack of fluidity in injection molding?

A:

In the early stage, we must understand the size of the customer's product structure firstly, whether the number of holes and the gate will affect the molding of the product. Whether the material fluidity will affect the injection molding temperature, whether the setting of injection pressure and mold temperature setting is reasonable, etc.

Q:

How to choose the reinforcement method and length of the material when using long fiber-reinforced thermoplastic material?

A:

The selection of materials depends on the requirements of the products. It is necessary to assess how much the content is enhanced and how much length is more appropriate, which are depending on the performance requirements of the products.
