FireShield® W: based on ammonium polyphosphate, but a non-hygroscopic form of
the product, so it can also be used in exterior applications where
weathering may be a concern.
FireShield® HT-W: a form suitable for the higher temperature (HT) curing epoxy resins,
common in aerospace, subject to weathering.
ATH – Aluminium TriHydrate
FireShield® ATH: when an ATH-filled composite is subjected to temperatures above
230°C/446°F, the ATH exfoliates 35 per- cent of its weight as water
while the remainder becomes inert (noncom- bustible) aluminum
oxide (Al₂O₃). This reaction is endothermic, or heat absorbing;
the water acts as a heat reducing agent to hinder fire spread.
MDH – Magnesium Hydroxide
FireShield® MDH: MDH decomposes at a higher temperature than ATH, making it
useful when working with engineering thermoplastic resins, such as
polyamides and polypropylene.
Select carrier (substrate) properties to suit needs of laminate manufacture.
Both satin and plain weave glass cloth substrates exhibit some degree of chemical shedding, as the glass area available for bonding is lower than in the case of tissue. The degree of shedding, at around 2% of gross weight, is not sufficient to impact on the fire protection, nor does it provide any health hazards, but it is unacceptable in clean-room situations. In such cases, the FireShield® can be converted into a Pre-Preg form.

A range of chemical types & substrates provides fire protection for most composite laminates, whilst allowing optimum laminate strength and stiffness - no filling required in the base resin.
