How to make PBO Endless Felt

PBO fiber

PBO material is prepared by solution polycondensation of 4,6-diaminophenol hydrochloride and terephthalic acid with polyphosphoric acid as solvent. It is a reinforcing material for composite materials developed by the United States in the 1980s for the development of the aerospace industry.
The strength is 5.8GPa, the modulus is 280GPa, which is the highest among the existing chemical fibers; the heat resistance temperature reaches 600℃, the limiting oxygen index is 68, it does not burn or shrink in the flame, and the heat resistance and flame resistance are higher than any other An organic fiber. Mainly used in heat-resistant industrial textiles and fiber-reinforced materials.

PBO material


Carding machine opens and combs heat resistant fibers to remove impurities.
The curled or lumpy fiber mass will become a state of a straight single fiber.
And At the same time, in the ginning process, it can remove the impurities and short lint in the fibers.
Ensuring the uniformity of the warp and weft tensile, length, and number of yarns in the base fabrics, under strictly controlled temperature and humidity conditions.
In the final stage of carding, the needle machine will punch the pure PBO fibers to become the high heat felt layer.

How to make high temperature felt

Weaving Laying

The fiber enters the web-laying machine, takes an approach to automation using robots, ensures consistent high quality and productivity.
The web-laying trolley is driven by toothed belts to cross-fold the PBO fiber single web output from the carding machine.
Our weaving employs sophisticated tension management technologies to make it into a multi-layer web with the required width and unit weight.

High temperature felt manufacturer


Full resin or semi-resin treatments are available to improve the wear resistance and durability of the PBO Kevlar conveyor belt. It also prevents aluminum swarf or dirt from sticking to the industrial felt, reducing damage to the surface of aluminum profiles.

Felt manufacturing process


The PBO heat resistant belt is cut with an electric rotating fabric cutting machine. Whether in terms of specifications or quality, Pure® felt tubes can perfectly meet customer needs. Using superb technology and machinery, cut out the size required by the customer, and cut out the edge-free Industrial felt roller.

All the finished products will be inspected by our professional-quality control staff with metal detector equipment, to ensure all products are inspected and there are no broken needles inside the heat proof PBO belt covers. Foshan Pure technology always insists that we’ll only deliver the goods to our customers after our products pass a series of rigorous tests.

Frequently Asked Questions

Q: What information do I need to provide?
A: Need to provide Seamless belt size, machine model and picture, delivery address, and zip code to calculate shipping

Q: What is the process of placing an order?
A: Contact us for PBO conveyor belts size and quotation, We provide you with an invoice-remit the money to the bank account-arrange the heat resistant felt production after receiving the payment-settle the balance before shipment- send out the felt rollers – receive the goods

Q: Are there any additional costs?
A: Additional taxes and fees are determined by your local customs duties

Q: Where is the origin of the fiber?
A: The low-temperature fiber polyester has a temperature resistance of 180 degrees and is produced in Yantai, China.
Nomex, a medium-temperature fiber with a temperature resistance of 280 degrees, comes from the USA.
The high-temperature fiber Kevlar has a temperature resistance of 480 degrees and is produced in the USA.
The PBO fiber has a temperature resistance of 600 degrees and the place of origin comes from Japan.

Q: Will the color of the PBO endless belt conveyor stay the same? What factors determine if the color changes?
A: The PBO conveyor belts will change color regardless of whether it is used or not.
When the PBO felt belt is not in use, it will be affected by light and air oxygen, and it will turn into a darker yellowish brown, but it will not shine.
In the state of use, it will become dark brown under the influence of temperature, and the surface will be shiny.
