Construction Polyester Fiber Manufacturer

PET is also known as polyester. It is a synthetic polyester fiber made from petroleum-based products. It is a high-performance fiber that offers a range of properties. For example, high tensile strength, thermal stability, and chemical resistance.


Yuanwang is your reliable PET fiber manufacturer in China. Our polyester fiber is commonly used in various applications. With its versatility and durability, Yuanwang polyester material has become an increasingly popular construction material in manufacturing.


  • PET fiebr is thermal stable.
  • PET fiber has a high tensile strength.
  • Polyester fiber has certain chemical resistance.
  • Improve crack resistance at low temperature.

Polyester Fiber Properties and Features

Properties of polyester fiber include high tensile strength, which makes it ideal for use in construction applications where reinforcement is needed. It also has thermal stability. It can stand high temperatures without losing its strength or durability.


Yuanwang construction grade pet polyester fiber is also a resistant chemicals. It is an ideal material for packaging and other applications where chemical exposure is a concern.

Yuanwang PET Fiber Uses in Concrete or Cement

Yuanwang polyester fiber is made of polyethene terephthalate. It is a type of plastic known for its strength and durability.


PET fiber is added to the concrete, asphalt or cement mixture, which helps to reinforce the material and make it more resistant to damage.

Improved Strength

PET fiber helps strengthen the concrete by bonding with the material and adding tensile strength. It makes the concrete more resistant to cracking and other forms of damage.

Reduced Shrinkage

Yuanwang polyester fiber helps reduce shrinkage when the concrete cools after being poured. It also improves the concrete’s resistance to freeze-thaw cycles.

Improved Durability

PET fiber makes concrete or cements more durable. And better able to withstand extreme temperatures, humidity, and other environmental factors.

Which type of fiber is best suited for use in asphalt concrete?

Both PET fibers and PAN fibers are suitable for use in asphalt concrete. The choice depends on the operating temperature:


– For temperatures below 200°C, use polyacrylonitrile fibers(PAN)in the mix.

– For temperatures above 200°C, use polyester fibers(PET) in the mixture.


Main Benefits of Polyester Fibers:

1. Improve High-Temperature Stability:

PET fibers have a three-dimensional distribution frame. Their strong adsorption with asphalt enhances viscosity and cohesiveness.


This reduces asphalt flowability and restricts lateral displacement or flow of aggregates. Improving high-temperature stability and the stability of fiber-reinforced asphalt concrete.


2. Low-Temperature Crack Resistance:

The adsorption effect of fibers increases the optimal asphalt content. Allowing the mixture to maintain flexibility and high tensile strength even at -40°C.


PET fiber resists shrinkage stress. Enhancing low-temperature crack resistance and reducing the occurrence of thermal shrinkage cracks. PET fiber can also prevent the development of reflective cracks.


3. Improve Fatigue Resistance:

Adding polyester fibers uniformly in the mixture increases rigidity. It can improve the asphalt’s resistance to fatigue.


4. Enhance Water Stability:

Water stability means how well asphalt pavement holds up under traffic, and temperature changes when water is present.


Adding PET fibers makes the asphalt coating thicker. Helping prevent water from weakening the pavement and reducing water seepage.


The adsorption effect of fibers increases asphalt viscosity. So, the PET fiber improves the bond strength between asphalt and aggregates. Enhancing the interface film’s resistance to water stripping.

What is PET fiber?

PET fiber is a type of fiber used in concrete or cement. This fiber is made from polyethylene terephthalate, a type of plastic. PET fiber is used to reinforce concrete or cement. It can be used in asphalt as a filler.


PET fiber is strong and durable and is not affected by chemicals or UV light. This type of fiber is also fire-resistant.

How much PET fiber should I use in my concrete mix?

The amount of PET fiber needed will depend on several factors, including the application, the desired performance characteristics, and the properties of the concrete mix. Typically, PET fiber is added at a rate of 0.6-1.5 kg per cubic meter of concrete, but this can vary depending on the specific application.


We recommend consulting with a concrete expert or our Yuanwang technical support team for guidance on the appropriate amount of PET fiber for your project.

How is Yuanwang PET fiber used in construction?

Yuanwang polyester fiber is typically added to concrete during the mixing process. The fibers become dispersed throughout the concrete matrix and help to distribute stress evenly and prevent cracking. PET fiber is often used in slabs, pavements, precast elements, and shotcrete applications.

What are the benefits of using Yuanwang PET fiber in construction?

Using Yuanwang polyester fiber in construction can offer several benefits, including increased crack resistance, improved durability, reduced maintenance costs, and enhanced impact and abrasion resistance. Additionally, using PET fiber can help reduce the amount of steel reinforcement needed in concrete, which can lower construction costs and reduce the project’s environmental impact.

Is Yuanwang PET fiber safe to use in construction?

Yes! PET fiber is considered safe for construction applications. It is a durable and non-toxic polyester material. It is used in various industries, including construction. The polyester fiber offers excellent resistance to moisture, chemicals, and UV radiation. Making it a reliable and safe choice for reinforcing concrete structures.
