Thermafloc+

We have invented a custom, specifically engineered fibre that drastically improves AGM (Absorbent Glass Mat) batteries. Goonvean Fibres have changed the way batteries perform with Thermafloc+, a precision cut fibre with exceptional characteristics and benefits. The technical battery fibre is a solution for all, tailored specifically to enhance the performance and longevity of batteries – rigorously tested for optimal results.

Thermafloc+ can be produced at any length from 0.1mm – 12mm and in any packaging arrangement to suit. We offer samples, so contact us to make an order.

The technical fibre is ideal for lead-acid battery manufacturers looking for a solution that overtakes standard polymeric fibres. We have shortlisted seven benefits you need to know about our brand-new, engineered fibre Thermafloc+, including:

Low Shrinkage

Thermafloc+ precision cut fibre has low shrinkage properties and can retain its dimensional stability.

High Thermal Stability

Our custom engineered technical fibre can withstand heat for a long time without affecting its performance. Thermafloc+ has been rigorously tested and will retain its dimensional stability at extreme temperatures. That is why we accredit Thermafloc+ as ‘Stability Assured’.

Enhanced Performance

Thermafloc+ is reputable for its enhanced performance properties. Our solution is tailored to the needs of lead-acid battery manufacturers so that batteries are stronger and longer lasting. All our performance tests mimicked real life situations, so you can have confidence that Thermafloc+ will make your AGM battery perform, unlike anything you’ve seen before.  

Increases Longevity

Batteries like AGMs require higher grade, more technical fibres to withstand specific conditions. Combined with the benefits of low shrinkage and high thermal stability, Thermafloc+ will last significantly longer than your average polymeric fibre. This makes it a cost-effective fibre solution.

Specifically Engineered for AGM Batteries

AGM batteries were first developed in the 1970s’, predominantly used as backup power for telephones and computer rooms. However, over the years, their uses have evolved to suit vehicles such as aircrafts, cars, motorbikes, and submarines, as well as power banks and for military purposes. Goonvean Fibres have specifically engineered Thermafloc+ fibres for AGM battery manufacturers.

Good Resistance to Acids

Thermafloc+ has good resistance to acid, a key criteria in the requirements of materials used in battery manufacturing.

Dispersion Properties

Our Thermafloc+ fibre has prodigious dispersion properties. It can evenly disperse through low viscosity fluid to ensure there are no weak spots. Thermafloc+ does this without clumping or ribboning.
