Recently, some customers have consulted our engineers that when using teflon high temperature cloth in UV curing machine, why do some teflon high temperature cloth take a long time to use, and some teflon high temperature cloth will break.

Jiujiang PTFE Materials Co., Ltd, we are specializing in the production of Teflon products, we give you some suggestions as following.

The reason why high temp teflon cloth breaks when used in UV curing machine:

  • For some UV curing machines, the length of the roller is not the same on both sides, this situation will be obvious after careful inspection.
  • The active electric drum, the driven roller and the tension roller adhere to irregular drops, easily cause large-area breakage of the high temp teflon cloth.

Therefore, we strongly recommend that you clean drops regularly.

The tips for the use and storage of teflon coated cloth:

  • In the transmission, pad rags, leading, etc. can be used to avoid damage to the ribs; the rigging should not be used during installation, and wooden shafts or steel pipes can be used to avoid damage to the base belt and the ribs.
  • Teflon coated cloth has higher requirements on the drum than the ordinary belt. Under normal circumstances, it is larger than the diameter of the drum used in the ordinary belt, so the large-diameter roller is preferred.
  • The teflon coated cloth must be transported by the roller and the carrier pulley in the UV light curing machine to avoid the slippage of the high temperature cloth during operation.

Jiujiang PTFE Materials Co., Ltd. is a factory that produces and develops PTFE products. In the past, we have been providing OEM processing to foreign trade companies. Now we provide direct sales of products directly on the basis of processing.

All our products are available for free samples and customized services. Whether it is the product displayed on our website or your special requirements for PTFE other products, such as food grade, high temperature resistance, smoothness, etc., as long as you have doubts, you can contact our engineers, we will be provide the most suitable product solution for you.

The fiberglass cloth woven by the loom has good insulation, heat resistance, good corrosion resistance and high mechanical strength. The glass fiber cloth and PTFE emulsion are processed to produce PTFE products, such as common PTFE baking mats, PTFE conveyor belts, and PTFE high temperature tape.

The PTFE high temp fiber glass adhesive tape not only has the physical characteristics of the raw glass fiber cloth, but also possesses the characteristics of the PTFE material. Details as follows:

  • Climatic resistant, anti-aging, working range: -70℃~300℃.
  • Non-sticky, easy to clean.
  • Chemical resistance, resisting the corrosion of strong acid & alkali, organic solvent.
  • Drug resistance, non-toxic, resisting all kinds of pharmaceutic products.
  • Excellent insulation performance, ant-UV, anti-static.
  • Fire retardant.
  • Easy to use, long service life.

Because of these features, the usage value of PTFE adhesive tape is far more than the common high temp fiberglass adhesive tape.

Teflon high temperature cloth can be used as high-temperature cushion in the production process of resin grinding wheel. The anti-viscosity properties of Teflon material are used well in product performance. At the same time, high-strength fiberglass cloth has excellent temperature resistance, tensile strength, breathability and so on. These make the entire grinding wheel manufacturing industry free from the problems existing in traditional technology, and raise its level to a new height.

Using Teflon high temperature cloth as a grinding wheel molding process of high temperature diaphragm has the following advantages.

The surface of the grinding wheel is neat. The surface roughness and self-sharpness is improved, and the heat dissipation is good when cutting.

Because of the thin thickness of Teflon high temperature cloth (only 0.5MM), the low heat capacity makes the heat transfer speed increase, the sintering time of grinding wheel is shortened, and the energy saving is more than 20%.

Workers operating labor intensity is reduced. Work efficiency is improved. Especially the grinding wheel is separated without adhesion phenomenon, so it no longer need beat vibration. The finished product pass rate can be increased by 25% compared with the past.

Teflon high temperature cloth that is invented by the DuPont Company in United States is a new type of demoulding material, which can replace the old-fashioned release agent. It uses PTFE and fiberglass cloth as the main raw materials, and adopts a unique impregnation process.

Teflon high temperature cloth is now widely used in a variety of rubber and plastic molds. For example: synthetic rubber conveyor belt, tires, shoe mold, rubber crawler, rubber pad, manufacturing polyethylene mold, rubber conveyor belt, the mold of epoxy and phenolic resin products and so on.

Several advantages of Teflon high temperature cloth:
1. No release agent, low costs and environmental pollution.
2. It can ensure the complete demoulding, and the scrap rate reduces largely.
3. It is easy to demould is and does not easily bond with the products.

Common PTFE fiberglass adhesive tapes are divided into two kinds: the narrow tapes are normally without release paper and the wide ones are always with release paper as shown below.

Temperature resistance of these both tapes can reach 300°C. Because of their heat resistance properties, they are often used in packaging, thermoplastic, composite, heat sealing, electronic and electrical industries.

PTFE (Teflon) cloth has excellent properties of anti-corrosion, anti-adhesion, high temperature resistance, insulation, which is widely used in industrial production. For example, the food industry, the chemical industry, the machinery industry, the electronics industry, etc. PTFE cloth also can be used as an insulating material, or covered edge material of PTFE (Teflon) conveyor belt.

PTFE cloth and PTFE conveyor belt for drying application

1. Drying conveyor of Urea and NPK compound fertilizer, polyvinyl chloride acetate, polyvinyl alcohol, urea formaldehyde resin, melamine formaldehyde resin, phenol formaldehyde resin, polyacrylate, polycarbonate, styrene butadiene resin and polyoxymethylene.

2. Drying of ceramic raw materials, such as ferrite, tungsten carbide, saponite, kaolin, alumina and titanate.

3. Drying of medicines, such as vitamins, antibiotics, enzymes, dextrin, liver essence, culture medium and Chinese herbal plant extracts, etc.

4. Drying of instant foods, such as whole milk powder, skimmed milk powder, malted milk, soluble fish meal, fish paste and fish protein.

If there in any question during using the PTFE(Teflon) conveyor belt, pls email to, our engineer will reply you within 24 hours.

Teflon mesh belt is food grade with excellent high temperature resistance and large number of users, but it will be worn when it is used, especially 24 hrs continuous working will accelerate the wear and tear of teflon coating.

In order to prevent car engine wearing, people use oil to lubricate machinery equipment. The teflon mesh belt transported all day long without interrupt, what we need to do after the wear and tear is to repair. The repair work is based on the wearing condition of the conveyor belt.

If the main structure is in good condition, only the edge of belt is damaged, then we only repair the damaged part with a high temperature iron & teflon film.

If any big damage in the middle of the mesh belt, please stop using it to avoid breakage.

If there is damage to the joint, it may cause the breakage of the belt if the transmission is continued, in this case, a new joint shall be made and replaced the damaged joint, then you can use the belt.
