DaesangTechlon Co., Ltd. uses a new material named PTFE, based on the highest technology and know-how of the employees. With this, the products create a non-corrosive environment, and by securing the new material ETFE, the company is also capable of erecting chemical plants. GUNHO E&C Co,. Ltd. will provide the best products as a partner of DaesangTechlon Co., Ltd., which focus on customer satisfaction with innovative technologies, in the Ulsan region.
The most typical of the lined product is the insert lining, which has been developed through years of experience and know-how of the technical research team of Daesang Techlon, Chemical, petrochemical, and pharmaceutical, as well as food industries are using these products for processes which require high resistance against high temperature and corrosion, as well as non-adhesiveness.

Thermal Resistance (Max. Operating Temperature) | ![]() |
120°C | ![]() |
The thermal resistance of 100℃ PTFE is rather high. But, the thermal resistance of the adhesive is low. | ![]() |

Adhesion Strength | ![]() |
The resin is welded, making it possible to use the material under negative pressure. | ![]() |
High adhesion strength ensures no local air layers after attachment reducing the risks of separation | ![]() |
The resin is welded, making it possible to use the material under negative pressure. | |
Resistance Against Permeation | ![]() |
No infiltration, as the product is formed as a single piece in a 3mm or higher thickness. | ![]() |
The sheet itself is not permeated. But the welded part can have PIN HOLES |
![]() |
The coating thickness is thinner. Therefore, infiltration is feared after a prolonged usage. (Max.1000㎛) |
|
Non-Adhesion | ![]() |
A single-piece structure. Due to the characteristics of TEFLON, the surface tension is low, improving the non-adhesion property. | ![]() |
Foreign objects may stick to the sheet welding part | ![]() |
