TEKCLEAN

TEKCLEAN is a new patented Antibacterial product developed under the request for utilization in human spaceflight environment by the “Cleanliness & Bio Resources” department of Thales Alenia Space. It has been tested according ISO 22196:2007 “Plastics – Measurements of antibacterial activity on plastics surfaces”.

D-TEKBLUE

D-TEKBLUE is a FDA approved blue PTFE detectable using optical scanner, metal detection equipment or X-ray equipment, whatever the type of food has been processed. This ensures that each fragment can be identified rapidly avoiding critical food contamination.

PTFE G673

PTFE G673 is a new patented stainless steel filled PTFE developed to overcome surface finish problems after CNC and mechanical machining of standard SS filled PTFE. Composed of a unique blend of PTFE and special SS 316L powder PTFE G673 defines new standard for PTFE compounds in terms of mechanical strength, toughness, elasticity, durability and surface finish.

TEKPORE

POROUS PTFE Porous PTFE grades are produced from suspension PTFE powders and specifically they are a mixture of different particle size distributions and hardness degrees to achieve the desired level of porosity.

TEKSEALING

HIGH PERFORMANCE SEALING SOLUTIONS Special rings for all hydraulic applications where the PTFE compounds are able to grant high wear resistance, low friction even without lubrication, perfect sealing at low, medium and high pressures. Not only virgin PTFE, but mainly compounds with bronze, carbon glass fiber.

TEKSLIDE

HIGH PERFORMANCE FLUOROPOLYMER MATERIALS Beside the wide range of the existing PTFE products, GUARNIFLON® developed the TEKSLIDE® products, PTFE compounded grades used in the processing of tapes, bearing tapes and machined parts retaining the usual and well known conventional PTFE advantages improved.

Tekbond

PTFE films provide a conformable release surface and exhibit a remarkably low coefficient of friction and nonstick properties. PTFE films have high temperature resistance and are virtually unaffected by all chemicals. At elevated temperatures, PTFE films retain excellent tensile strength.

Film applications include high temperature coil and capacitor wrapping, composite bonding, masking and conveyor release linings.

ADHESIVE SYSTEMS

SILICONE

Perfect for extreme temperature applications, silicone adhesive perform in continuos service temperature from -73°C up to 260°C. Silicone based adhesive system exhibit good chemical resistance, retain electrical properties.

ACRYLIC

Acrylic adhesives perform in continuous operating temperatures from -40 °C to +177 °C. Benefits include exceptional solvent resistance, excellent adhesion to metal, superior weathering and aging characteristics.
Acrylics have an excellent shelf life and when exposed to elevated temperatures their ability to wet-out improves thus increasing both adhesion and tack properties. Acrylic dhesives will generally thermoset when exposed to heat.
The adhesive will then exhibit increased strength and improved thermal capabilities.

RELEASE LINERS

PVC

A general purpose release liner, PVC conforms well to tape and protects the adhesive during handling. Although these liners have good release properties and slit well, they are generally not used for die-cutting. Only available with silicone adhesive tapes, a yellow liner is standard. Corrugated liners are standard on most PTFE coated fabrics, whilst dimpled liners are used on the majority of thermal spray tapes.

POLYETHYLENE

These thin release liners not only conform well to tape, but slit and release easily, making them a sensible choice for die-cutting. Available with acrylic adhesive systems, a smooth blue release liner is standard on most acrylic-adhesive pressure sensitive products.

PAPER (COATED)

Paper is the ideal choice for die- and kiss-cutting. They have the advantage of lost cost and excellent release characteristics. Available with silicone rubber and acrylic adhesive systems, these beige release liners are specially treated to ensure excellent release properties.

FLUOROSILICONE

This release liner incorporates advanced release technology for use with silicone adhesives. As a flat, diecutable liner, it has exceptional release properties, making it an ideal choice for small or complex parts.
