Thermoplastic fibres such as polyester and nylon soften and flow when heated. In a fire, a garment made from them melts and adheres to skin, continuing to transfer heat after the flame is gone.

Para-aramid has no melting point in that sense. Under sufficient heat it chars and carbonises, forming a rigid layer that stays in place. The fabric remains a barrier rather than becoming a heat source held against the wearer. For protective clothing this distinction is the entire reason the fibre is specified.

Treated FR is an ordinary fibre with a flame retardant chemical applied. The treatment works while it remains present, and it reduces with washing, abrasion and time. Treated garments therefore carry a wash count limit.

Our yarn is inherently flame resistant. The property is in the polymer molecule, so nothing was added and nothing can wear off. It performs identically on its first day and after hundreds of wash cycles. For high risk work or long service life, that difference is the whole argument.

Tenacity is strength, measuring how much force the yarn carries before breaking, expressed relative to its linear density. Ours is 21 cN per dtex. Modulus is stiffness, measuring how much the fibre resists being stretched. Ours is 88 GPa.

They are different requirements. A yarn can be strong but stretchy, or stiff but brittle. Para-aramid delivers both, which is unusual and is often the reason it is chosen over cheaper fibres that match it on one measure alone.

Because of the modulus rather than the strength. Fibre optic cable gets pulled hard during installation and must not stretch, since strain on the glass fibre inside degrades the signal long before anything physically breaks.

Aramid yarn takes that tensile load while adding very little weight and no electrical conductivity, which matters for cables running near power infrastructure. The combination of high modulus, low weight and non conductivity is why it became the standard strength member.

Choose on the function rather than on temperature alone. Para-aramid is light, strong, cut resistant and comfortable enough to wear. High silica is far more heat resistant but heavier, stiffer and not suited to worn garments.

If a person is wearing it or a structure depends on its tensile strength, aramid is usually right. If it sits against a furnace or takes molten metal spatter, high silica is. Where a genuinely high temperature requirement arrives, we will say so rather than push aramid beyond where an organic fibre belongs.

Para-aramid is generally sensitive to prolonged UV exposure. This is a characteristic of the polymer family rather than of any one supplier's product.

In most applications it does not matter, because the yarn sits inside a cable, inside a composite, or beneath an outer fabric layer. Where the fibre would be directly exposed outdoors for years, raise it at inquiry stage so it can be designed around rather than discovered in service.

Natural yellow is the undyed colour of the fibre itself, which is why so much aramid product in the market is that colour and why it is the lowest cost option.

Black and custom colours are available. Colour is introduced during production rather than applied afterwards, so it must be specified at order stage and carries its own minimum quantity.

Yes. We also supply para-aramid fabric for protective clothing and reinforcement, and para-aramid short staple fibre for friction materials, gaskets and dispersion into compounds.

If you are building a product line that needs more than one form, sourcing them from one plant keeps the fibre specification consistent across the range rather than mixing material from several origins.

Yes. For a yarn destined for weaving or braiding we would rather you ran it on your own equipment than took the specification on trust, since machine behaviour varies between workshops.

Tell us the process and the machine when you request a sample so we send something matched to it rather than a generic length.

Protective clothing frequently has to meet a specific standard in the destination market, and the fibre specification forms part of that documentation package.

Tell us at quotation stage which standard your end product is being certified to and what documentation your approval process requires, and we will confirm what we can provide with the shipment rather than after it.

Standard specification in natural yellow carries a lower minimum because the material already exists in that form. Custom colours and non standard specifications need their own production run, which raises both the minimum and the lead time.

Tell us the specification and your rough volume and we will confirm the exact figure with your quotation.

Payment is normally by T/T, structured as a deposit with the balance settled before shipment. We confirm the exact split with your quotation.

EXW, FOB, CIF and DAP terms are all available, so you can pick whichever fits how your freight is already arranged. If you have a nominated forwarder we will work with them directly.
