T-Link™ Technology

Beyond Limits

T-Link™ is our advanced engineering thermoplastic resin that combines superior adhesion with the processing characteristics of a thermoplastic.

What is T-Link?

T-Link™ is an enabling technology that helps you go beyond limits

L&L Products meets a long-existing industry need with T-Link™, an advanced engineering thermoplastic adhesive hybrid resin that does not require refrigeration or special handling and – being highly customizable – can be easily and quickly consolidated into a composite structure.

T-Link™ is a good candidate when typical thermoplastic adhesive films are not performing sufficient enough. Due to its thermoplastic nature, T-Link™ is drapable for deep drawn parts allowing for production of irregularly shaped components. T-Link™ is commonly used to replace messy and time-consuming liquid epoxy solutions.

Product Portfolio

T-Link™ is available in a range of melt viscosities, enabling a tailor-made solution in multiple forms*, including resin pellets, transparent film, expanded film, monofilament, multifilament, coated yarns, powder, fiber veil, and unidirectional composite/tape.

* Some T-Link™ technologies in this overview are still in development phase.

Create stronger reinforcement

T-Link™ comes in pellet form and is both injection moldable and extrudable. The recyclable resin is typically used in other formulations as a toughener. T-Link™ is unique in that it has a high strain-to-failure and exhibits excellent adhesive properties.

These attributes make T-Link™ resin an ideal solution for composite manufacturers that are seeking a highly customizable composite reinforcement that will be strong and not suffer from brittle failure.

Dry-to-the-touch for easy handling

T-Link™ film is a dry-to-the-touch, engineered thermoplastic adhesive that demonstrates 99% optical clarity, therefore, it does not disrupt intended color and allows for light transmission where applicable.

T-Link™ film can be processed with traditional press equipment and has a short cycle time for bonding, does not require refrigeration, and has a long shelf life. Additionally, it has low odor and is printable and pigmentable.

Reinforcement for textile applications

Our novel T-Link™ yarn is used as a vehicle to introduce a resin into an advanced composite fabric in order to achieve high strength, toughness, and ease of use. T-Link™ yarn can effectively be co-woven or sewn into textile applications to make a dry thermoplastic composite with targeted and precise control of resin content.

Create stronger composite reinforcement

You can use T-Link™ in powder form as binder resin for textile and nonwoven industry, or as the particulate heat activated adhesive for composite manufacturing. Our resin is unique in that it has a high strain-to-failure up to 40 percent and exhibits excellent adhesive properties.

The recyclable T-Link™ powder offers a particle size distribution of 200-450 microns with an average of 300 microns and has a long shelf life.

Lightweight adhesive layer for stability

T-Link™ veil is a dry-to-the-touch, engineered thermoplastic adhesive that demonstrates 99% optical clarity, therefore, does not disrupt intended color and allows for light transmission where applicable.

T-Link™ veil has a lower areal weight than T-Link™ film, but also offers a short cycle time for bonding, does not require refrigeration, and has a long shelf life. The veil can be used as a stabilizing layer for unidirectional tapes.

Thin and lightweight selective reinforcement

T-Link™ can be used as the matrix resin that impregnates with the fiber to produce unidirectional composites/tapes for selective reinforcement. It is compatible with a variety of structural reinforcement fibers, such as aramid, glass, carbon, etc.

The composite/tape can be used as a selective reinforcement to improve tensile strength and stiffness in one direction while adding minimum thickness and weight.

Potential
Applications

Being an advanced versatile thermoplastic matrix resin, T-Link™ can be used to create lightweight, highly customizable composite structures that empower performance with processibility in a wide range of markets and potential applications.
