PET Fiber, also known as Polyester Fiber, is a synthetic fiber made from polyester as the main raw material, adding certain functional masterbatch. PET fibers are increasingly being used in concrete as a reinforcement material to enhance its durability, strength, and workability.
The density of PET fiber is 1.36g/cm3. The moisture absorption is very small. The fibers are not brittle or deformed in the temperature range of - 40 250 C. Each fiber is independent. It has strong adsorption with asphalt and good adsorption and dispersion in medium. When 2250 grams of fibers are added to each ton of asphalt mixture, up to 1.8 billion fibers will be reinforced in three-dimensional way, providing huge cohesion and improving the quality and life of highway.
Product Features:
- PET fibers have excellent strength and bonding properties, making them an ideal choice for concrete reinforcement.
- They improve the freeze-thaw resistance of concrete, reducing the likelihood of cracks and damage.
- The fibers are non-corrosive and do not rust, ensuring longevity and durability in concrete structures.
- PET fibers are cost-effective and environmentally friendly, as they are produced from recycled plastic bottles.
- The fibers are easy to mix with concrete and do not clump or ball together during mixing.

Application:
- New and old asphalt concrete pavement cover
- Air film layer (waterproof layer) is built on bridge deck.
- Enhancement of airport runway and apron
- For new and old concrete cover
- For concrete and steel bridge face
- Reinforcement and repair of pavement

Storage:
PET fibers should be stored in a cool, dry place to prevent moisture absorption and maintain their mechanical properties. They should be kept away from direct sunlight, heat, and flames.
FAQ
Q: Are PET fibers stronger than steel fibers?
A: PET fibers have a lower tensile strength than steel fibers, but they are more flexible and do not corrode, making them a better choice in certain applications.
Q: Can PET fiber replace rebar in concrete reinforcement?
A: While PET fibers can improve the strength and durability of concrete, they cannot replace rebar entirely. Rebar provides a primary structural support system and should be used in combination with PET fibers for optimal results.
Q: Can PET fiber be recycled?
A: Yes, PET fibers can be recycled, and many manufacturers produce PET fibers from recycled plastic bottles.
