Teflon tape is also called Polytetrafluoroethylene tape(PTFE tape), which is coated with Teflon resin on the basis of fiberglass fabric. It is smooth, anti – stick, bright and resisting all kinds of chemical corrosion. The application range of teflon tape is relatively wide, mainly used in packaging, thermoplastic, composite, sealing thermal bonding, electrical and electronic industries. It can be used in the place where need the anti-adhesive thermal bonding corrosion resistant insulation and where need the repeated paste function.

Standard size of the teflon tape

The standard width of Teflon tape is 1M or 1.25m, which can be cut with small specifications and high-precision. The cutting tape is divided into two types: tape with release paper and tape without release paper. The thickness of common teflon fiberglass tape is 0.13 ~ 0.40mm, and the thickness of pure teflon tapes is 0.08 ~ 0.5mm. Other special specifications can be customized.

Colors of the teflon tape

The colors of teflon tape are: brown, black, white and blue. Special colors can be customized.

The temperature range that teflon tape can be used

Another big advantage of teflon tape is that its excel performance of high temperature resistance. It is different from the impression that the tape shrinks and burns when caught on fire in our traditional understanding. Teflon tape can be used normally at a high temperature of 260 degree. Some customized Teflon tape can be used normally at temperatures of 300 degree.

Teflon tape is very convenient to use, can reduce the labor intensity, it is premium products.

Project aims to realize prepreg substrate materials for automotive applications

DIC announced that its project in partnership with the Fukui Seiren and Fujinsi County Industrial Technology Centre had been selected by the new Energy and Industrial Technology Development Organization (NEDO) as the main research project for the Strategic Innovation Plan for fiscal year 2018. Energy-saving technologies (commercial development phase).The project focuses on the commercialization of fast curing prepreg for the manufacture of carbon fiber composites for automotive applications.

The NEDO program seeks to advance the development of technologies that will contribute to create an energy-efficient economy and society and/or improve the competitiveness of Japanese industry. The program selects and subsidizes technological development project with the potential to significantly reduce energy consumption. (Projects selected in fiscal year 2018 will be subsidized from fiscal year 2018 through fiscal year 2020.)

The project brings individual technologies by three specialists together; DIC’s radical-curing resin (cures in less than one minute at 150°C) that leverages its original polymer design technologies; the Industrial Technology Center of Fukui Prefecture’s tow spreading (processes fiber bundles into flat sheets) and high-speed prepreg processing technologies; and Seiren’s high-quality prepreg processing and quality management technologies. The goal is to develop fast-curing prepreg suitable for mass production that achieves both low production costs and high quality within the world’s shortest production time. The prepreg can also be stored at room temperature.

The project also includes the development of a high-speed manufacturing mass production process for commercialization and mass production of the new prepreg, which reduces the energy consumption required for production and molding and improves vehicle fuel economy by reducing vehicle weight. As a result, the project is expected to yield a 90,000 kl (crude oil equivalent) reduction in energy consumption in 2030.

In recent years, automakers have focused on reducing vehicle weight with the aim of boosting fuel economy. While this trend has driven a steady increase in the use of carbon fiber composite materials in vehicle challenges remain such as the final cost arising from expensive materials and slow molding speeds. DIC, the Industrial Technology Center of Fukui Prefecture and Seiren continue working together to achieve mass production of their new prepreg with the aim of overcoming this challenge and encouraging adoption by automakers. In doing so, the three organizations look forward to realizing a product that helps in further advance the popularity of carbon composite materials.

Because there are many suppliers in current market, Teflon tape’s quality is uneven. Most of customers pay attention to its sticky. For example, customers’ will is to use their own hands to test stickiness once getting a roll of tape. In fact, they certainly cannot test for the moisture, booty on their hands. We use steel to do the test in Teflon production, and the surface of the steel need to be very clean, which is a more formal test method. But many customers cannot do such test for the conditions limits. The best way should be glue itself with the face of adhesion, and then pull open. The greater the intensity of the pull, the greater the viscosity.

Teflon tape has many characteristics like anti-adhesion, high temperature resistance, corrosion resistance and so on, so it is widely used in various industries. Teflon tape has a wide variety, different colors, and different price according to different quality. Today, our Taixing, Yong Sheng fluorine Plastic Products Co., Ltd. specializes in the production of Teflon tape. At present, the thickness of Teflon tape is 0.13mm-0.3mm. Their color has coffee, blue, black, and white. And the black is divided into anti-static and non-antistatic. The price is RMB 40 yuan to 60 yuan. Our products are very popular since the listing.

Let us talk about that how long should the Teflon tape to be used, that the problem has been bothering a lot of customers. After testing and technical discussion, we found that the good-quality tape almost will not happen residual glue degumming in half a year. And the slightly low-quality tape that adhesive is not pure will have residual glue when using after half a year. Even in the moment of ripping off, glue has been falling off.

Some customers would like to order the amount of one year at a time. In fact, it is not beneficial for the usage and storage of tape. Tape will evaporate slowly in contact with the air. So the performance of the tape will reduce with the placement time. In order to make full use of Teflon tape, good-quality Teflon tape should be used in half a year, and the slightly low-quality tape should be used as soon as possible.

Please replace Teflon tape from Taizhou Co., Ltd. after a period of time, so as not to affect the quality of production.

Gasket

Gasket is a mechanical seal between two objects, usually used to prevent pressure, corrosion, and natural thermal expansion and contraction between the two objects. Since the machined surface is not perfect, the gasket can be used to fill the irregularities. The gasket is usually made of a sheet material such as mat paper, rubber, silicone rubber, metal, cork, felt, neoprene, nitrile rubber, fiberglass or a plastic polymer such as polytetrafluoroethylene. Gaskets for specific applications may contain asbestos. Washer is a hole (usually in the middle) of a thin plate (usually round) that is typically a load thread fastener for dispensing. Other uses are as spacers, springs (Belleville gaskets, wave gaskets), wear pads, pre-display devices, and lock devices. Rubber gaskets are also used in faucets (valves) to cut off flowing liquids or gases. Rubber or silicon gaskets can also be used to reduce fan vibration. Usually the outer diameter of the gasket is about twice the inner diameter.

Varnished cloth

First paint the background with oil paint, then add a few layers of tung oil, polish and paint all kinds of patterns with colored paint, and finally cover with a layer of oil. Specifications are generally 2x 3 meters(Equal to Kang size); It has both practical value and beautification. In North of China, fire Kang, with ramming mats, quilts, wool felts or blankets, and varnishes to protect the carpet is very common. This was popular in the 1970s and 1980s. Mostly handmade by folk artists.

Teflon high temperature cloth belt, Teflon high temperature mesh belt and Teflon tape are three extremely familiar words. In this bleak August, every order is really difficult. I always hold an inner gratitude for the customers who believe in me. At the same time, I am introspecting. I really do not know very well about the products I sell. I don’t know all of their uses yet. The longer it takes, the more I feel like a layman!

Was it ever all in vain? Is it just futile to post so much information and make so many calls? Or is it just a way of wrong? The past August makes me nervous. Golden nine silvers ten is a popular phrase. Will it really be great in September? Maybe it is a little self-deception! Time wasted, and I’ve always been the only one who let myself down. Performance has not risen, not because there is no business, but I give up the search!

Come on! September! There are only four months to go in 2018, and I need do something to make a different!
