For the last 100 years, synthetic polymers have been divided into two general categories: thermosets, which have excellent mechanical properties, but must be irreversibly cured prior to final use; and thermoplastics, which can be melted down and reprocessed, but have inferior thermal and mechanical properties.
Vitrimers represent a new class of polymers based on dynamically exchangeable imine-linked polymer networks. Like thermosets, vitrimers are highly crosslinked network polymers. However, unlike thermosets that are permanently in fixed form after curing, vitrimer chemistry yields a product that can be remolded. When heated above the glass transition, the fully cured network polymer undergoes rapid dynamic covalent bond exchange within the polymer network. This allows for facile processing of thermoset materials that can be heated to a specific temperature after being fully cured and reshaped. Upon cooling the materials retain thermoset-like mechanical performance.

The reversible nature of vitrimers enables covalent welding, molding, reshaping, and solution-based closed-loop recycling of fully cured materials. The chemistry is highly tunable to meet the thermomechanical requirements across industry segments. By way of example, Mallinda has formulated polymers with glass transition temperatures (Tgs) ranging from ~20 C - ~240 C.
Mallinda's patented Vitrimer resin platform eliminates the slow infusion and long curing cycles of today's resins; enabling compression-molding of products in just seconds for high-throughput, high-volume production of structural composites. In addition, our prepreg is pre-cured, shelf-stable, and requires no refrigeration for transport or storage.
Mallinda's vitrimer prepreg is a disruptive platform technology that enables rapid (< 1 minute) compression molding of fully cured thermoset composite parts. It is designed for fiber reinforced composite (FRC) production using rapid compression molding techniques analogous to sheet metal stamping. In addition, Mallinda’s resin can be recovered using reagents utilized in the resin synthesis. This is key to (1) allowing a circular, energy-neutral system for the recovery of resin and woven/full-length fiber that does not require the use of heat nor the introduction of any additional chemical components outside of our formulations for recycling; (2) enabling full recovery and re-usability of our resin.


Mallinda has developed a completely closed loop system for the recovery of both polymer and carbon fiber from CFRC end-of-life products and scrap materials. Our patented recycling process takes advantage of the reversible chemistry of our material, generating no excess waste, and using almost no energy. Both the recovered carbon fiber and the recovered resin can be reused to make fresh composite materials.


Mallinda’s vitrimer resins can be formulated to have a range of vitrimer transition temperatures. Our resins can be molded at temperatures as low as ~20 C and as high as ~240 C, depending on formulation. In some applications, this feature has the benefit of allowing end-users to custom mold our resin or composites derived therefrom, to suit the end user’s needs without the use of expensive and massive industrial equipment.

In addition, Mallinda's material can be formulated for a range of mechanical properties - from elastomeric to crystalline.


Due to the unique nature of vitrimer chemistry our prepreg and resin arrive pre-cured. There is no requirement for refrigerated storage and transport. Mallinda’s materials are indefinitely shelf stable under ambient conditions.


Mallinda’s resin may be recycled many times over. The fully cured resin may be isolated using precursors from the initial resin synthesis. After isolation, simply balancing the resin formulation as needed enables full reusability.


The plastic may also be ground into a powder and reformed into new shapes with heat and pressure. This both increases the input lifetime vis-a-vis recycling and reduces the energy required during re-purposing.

In addition, Mallinda's ability to implement solid state thermoforming could revolutionize production of powder-based composite materials.
