FTR (Tack prevention surface processing)

Most people would imagine that rubber is tacky and is used for non-slip materials.
If tires were slippery, it wouldn’t be possible for vehicles to turn round corners, or even to start up and stop.
Further, some of you may be protecting the screens of your mobile phones or laptop computers by covering them with scratch prevention films. Although the film material itself is not rubber, many of these films are attached to the screen with rubber-related substances. In this way, rubber is originally a non-slip substance that is tacky.
The reality, however, is not that simple. If rubber’s original “non-slip tackiness” is left as it is, rubber bands would end up as a single lump, and once you close gas taps, water taps, or car doors, some trouble would be required to open them.
For this reason, depending on the usage location and component, the rubber’s original “non-slip tackiness” may sometimes be inconvenient.

What is FTR?
Even among rubber products, some products are required to have a good sliding ability or to be non-tacky according to the application.
This difference can be realized using “FTR” surface processing.
FTR takes the initials of “Fujikura Tack Reducer”, and as the name suggests this is Fujikura Rubber’s surface processing that reduces the tackiness of the rubber or promotes sliding. Several types are available according to the application, including fluorine-based, silicone-based, and carbon-based types.

FTR processing is possible for almost all our rubbers. In addition, it has a design which maintains the most important quality of rubber; that it is very hard to peel off, even when stretched, compressed, or bent. For this reason, it is widely used in the following situations.
 ・Prevention of blockages of rubber components in parts feeders
 ・Lowering of the resistance when mounting O-rings, etc.
 ・Check (umbrella) valves of pumps operating at 50-60 hertz
 ・Prevention of tack in bellows made from rubber, etc.

Merits of FTR
 ・Effective for giving rubber non-tackiness and low-friction properties
 ・Follows the deformation and stretching of the rubber
 ・Hard to peel off
 ・Has been extensively applied to rubber products which repeatedly change their shape
 ・Tack prevention (or reduction) and friction reduction achieve a reduction in the required energy, resulting in energy conservation
 ・Tack prevention (or reduction) and friction reduction achieve a reduction of the required energy, which in turn shortens the operation time and reduces noise, resulting in an improvement of the quality of life.
 ・Tack prevention (or reduction) and friction reduction achieve a lengthening of the product life, resulting in improving the eco-friendliness.

FTR Main Applications
 ・Prevention of tack and sticking between rubber components such as valves and opponent materials
 ・Prevention of tack and sticking between rubber components such as shape-changing umbrella valves and the bodies
 ・Prevention of tack and sticking between fellow rubber components such as O-rings
 ・Prevention of tack and sticking of rubber components themselves, such as rubber bellows, which change their shape
 ・Reduction of resistance when mounting rubber components

FTR can be applied to applications other than those described above, and we will support you in response to your requests.
