Zotek F Material & Applications

ZOTEK® F

ZOTEK F is a new range of lightweight, closed cell, PVDF (polyvinylidene fluoride) foams based on Kynar® fluoropolymer, a remarkable material that offers a unique balance of properties.

Kynar PVDF fluoropolymer has excellent UV, nuclear radiation and ageing resistance, high dielectric strength and outstanding resistance to a wide range of solvents and aggressive chemicals. It is biologically inert, thermally stable across a wide temperature range (to 160°C) and has a very low order of toxicity. It is inherently flame retardant releasing very little heat and only small quantities of smoke during combustion.

In ZOTEK F, these properties are combined with light weight, flexural response, buoyancy and thermal and acoustic insulation properties derived from the foaming process. Like their parent resins, ZOTEK F foams will exhibit outstanding durability and longevity.

RANGE OF HIGH PERFORMANCE FLUOROPOLYMER FOAMS

The new ZOTEK F HT and ZOTEK F HT LS foams offer an operational temperature limit of 160°C, an improvement of +50°C over the current ZOTEK F range. They also offer enhanced chemical and solvent resistance, combined with higher levels of structural rigidity.

ZOTEK F HT LS (Low Smoke) is recommended for use in a variety of sealing and insulation applications in the semiconductor, pharmaceutical and chemical processing industries, where exceptionally low smoke release is required in the event of fire.

ZOTEK F 40 HT LS is listed to UL 723/ASTM E-84 (Standard Method of Test of Surface Burning Characteristics of Building Materials).

ZOTEK F 42 HT LS is used for conversion into T-Tubes® a revolutionary, advanced insulation system specifically developed for stainless steel process lines in clean environments. This is the first foam insulation that has successfully achieved the approval criteria of the FM Approvals FM 4910 Standard "Clean-room Materials Flammability Test protocol'.

CONVERSION
All ZOTEK F grades can be manipulated using conventional foam conversion methods, such as die-cutting, water jet cutting, sawing, laminating and welding into continuous rolls. They can also be thermoformed into complex single component structures providing benefits over multi-layer foam systems, such as weight and cost reduction.

APPLICATION
ZOTEK F, ZOTEK F HT and ZOTEK F OSU are used extensively in the commercial, business and military aircraft and aerospace industries, having excellent insulation properties and meeting the stringent industry flammability requirements. See our aviation flyer.
Excellent flammability performance also allows ZOTEK F foams to be used as low closure force seals for electrics/electronics applications.ZOTEK F foams have the potential to meet the requirements of UL94 with class V0 (only indicative test results are currently available).
Being unaffected by UV radiation, ZOTEK F can be used for high specification building and construction projects with applications ranging from expansion jointing and ridge closures through to tunnel insulation. ZOTEK F has also been shown to meet the EU Single Flaming Source and Single Burning Item tests with a Euroclass B rating.
The compliant nature and chemical resistance of ZOTEK F HT make it ideally suited to applications such as high and low closure force seals in chemically harsh environments or high purity are essential. ZOTEK F HT grades are recommended for general use in industrial applications such as chemical engineering, pharmaceutical and medical.
The military industry has also shown great interest in ZOTEK F and ZOTEK F HT grades for packaging and thermal insulation purposes. ZOTEK F 38 HT already has NATO codification.
